# Lending Protocol Examples (JavaScript)
|
||||
|
||||
This directory contains JavaScript examples demonstrating how to create a loan broker, claw back first-loss capital, deposit and withdraw first-loss capital, create a loan, manage a loan, and repay a loan.
|
||||
|
||||
## Setup
|
||||
|
||||
Install dependencies before running any examples:
|
||||
|
||||
```sh
|
||||
npm i
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Create a Loan Broker
|
||||
|
||||
```sh
|
||||
node createLoanBroker.js
|
||||
```
|
||||
|
||||
The script should output the LoanBrokerSet transaction, loan broker ID, and loan broker pseudo-account:
|
||||
|
||||
```sh
|
||||
Loan broker/vault owner address: rKL3u76wNGdF2Th4EvCuHV5885T6h2iFTY
|
||||
Vault ID: 33E51DD0333775E37F2CC1EB0DA788F9C663AF919DC23ED595A8D69330E5CD68
|
||||
|
||||
=== Preparing LoanBrokerSet transaction ===
|
||||
|
||||
{
|
||||
"TransactionType": "LoanBrokerSet",
|
||||
"Account": "rKL3u76wNGdF2Th4EvCuHV5885T6h2iFTY",
|
||||
"VaultID": "33E51DD0333775E37F2CC1EB0DA788F9C663AF919DC23ED595A8D69330E5CD68",

|
||||

||||
|
||||

|
||||

## Claw Back First-loss Capital
|
||||
|
||||
```sh
|
||||
node coverClawback.js
|
||||
```
|
||||
|
||||
The script should output the cover available, the LoanBrokerCoverDeposit transaction, cover available after the deposit, the LoanBrokerCoverClawback transaction, and the final cover available after the clawback:
|
||||
|
||||
```sh
|
||||

# Lending Protocol Examples (Python)
|
||||
|
||||
This directory contains Python examples demonstrating how to create a loan broker, claw back first-loss capital, deposit and withdraw first-loss capital, create a loan, manage a loan, and repay a loan.
|
||||
|
||||
## Setup
|
||||
|
||||
Install dependencies before running any examples:
|
||||
|
||||
```sh
|
||||
python3 -m venv .venv
|
||||
source .venv/bin/activate
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Create a Loan Broker
|
||||
|
||||
```sh
|
||||
python3 create_loan_broker.py
|
||||
```
|
||||
|
||||
The script should output the LoanBrokerSet transaction, loan broker ID, and loan broker pseudo-account:
|
||||
|
||||
```sh
|
||||
Loan broker/vault owner address: rBeEX3qQzP3UL5WMwZAzdPPpzckH73YvBn
|
||||
Vault ID: 2B71E8E1323BFC8F2AC27F8C217870B63921EFA0C02DF7BA8B099C7DC6A1D00F

# Single Asset Vault Examples (JavaScript)
|
||||
|
||||
This directory contains JavaScript examples demonstrating how to create, deposit into, and withdraw from single asset vaults on the XRP Ledger.
|
||||
|
||||
## Setup
|
||||
|
||||
Install dependencies before running any examples:
|
||||
|
||||
```sh
|
||||
npm i
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Create a Vault
|
||||
|
||||
```sh
|
||||
node createVault.js
|
||||
```
|
||||
|
||||
The script should output the VaultCreate transaction, vault ID, and complete vault information:
|
||||
|
||||
```sh
|
||||
Vault owner address: rLXZNDSS7gWvQZKunRUFiaViSiHo1yd4Ms

# Single Asset Vault Examples (Python)
|
||||
|
||||
This directory contains Python examples demonstrating how to create, deposit into, and withdraw from single asset vaults on the XRP Ledger.
|
||||
|
||||
## Setup
|
||||
|
||||
Install dependencies before running any examples:
|
||||
|
||||
```sh
|
||||
python -m venv .venv
|
||||
source .venv/bin/activate
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Create a Vault
|
||||
|
||||
```sh
|
||||
python create_vault.py
|
||||
```
|
||||
|
||||
The script should output the VaultCreate transaction, vault ID, and complete vault information:
|
||||
|
||||
```sh
|
||||
Vault owner address: rfsTcqjyg7j2xfJFNbd9u8mt65yrGZvLnu
|
||||
MPT issuance ID: 00385B21AF216177F319AC73F25F0FCBCDA09330D1D50D03

# GPG Key Rotation
|
||||
|
||||
Ripple has rotated the GPG key used to sign `rippled` packages. If you have an existing installation, you should download and trust the new key to prevent issues upgrading in the future. **Automatic upgrades will not work** until you have trusted the new key.
|
||||
|
||||
## Action Needed
|
||||
|
||||
Add Ripple's package-signing GPG key, then verify the fingerprint of the newly-added key.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Red Hat / CentOS" %}
|
||||
|
||||
```bash
|
||||
sudo rpm --import https://repos.ripple.com/repos/rippled-rpm/stable/repodata/repomd.xml.key
|
||||
rpm -qi gpg-pubkey-ab06faa6 | gpg --show-keys --fingerprint
|
||||
```
|
||||
|
||||
{% /tab %}
|
||||
{% tab label="Ubuntu / Debian" %}
|
||||
|
||||
```bash
|
||||
sudo install -d -m 0755 /etc/apt/keyrings && \
|
||||
curl -fsSL https://repos.ripple.com/repos/api/gpg/key/public \
|
||||
| gpg --dearmor \
|
||||
| sudo tee /etc/apt/keyrings/ripple.gpg > /dev/null
|
||||
gpg --show-keys --fingerprint /etc/apt/keyrings/ripple.gpg
|
||||
```
|
||||
|
||||
Ensure the `signed-by` path in your Ripple source list refers to the location the key was downloaded. For example, on an Ubuntu 22.04 Jammy installation, `/etc/apt/sources.list.d/ripple.list` would contain:
|
||||
|
||||
```
|
||||
deb [signed-by=/etc/apt/keyrings/ripple.gpg] https://repos.ripple.com/repos/rippled-deb jammy stable
|
||||
```
|
||||
{% /tab %}
|
||||
{% /tabs %}
|
||||
|
||||
The output should include an entry for Ripple such as the following:
|
||||
|
||||
```

# Introducing XRP Ledger version 3.1.0
|
||||
|
||||
Version 3.1.0 of `rippled`, the reference server implementation of the XRP Ledger protocol, is now available. This release introduces Single Asset Vaults, the Lending Protocol, and bug fixes.
|
||||
|
||||
|
||||
## Action Required
|
||||
|
||||
If you run an XRP Ledger server, upgrade to version 3.1.0 as soon as possible to ensure service continuity.
|
||||
|
||||
|
||||
## Install / Upgrade
|
||||
|
||||

|
||||
## Full Changelog
|
||||
|
||||
|
||||
### Amendments
|
||||
|
||||
- **SingleAssetVault**: Adds vaults, which pool a single asset for use with the Lending Protocol. ([#5632](https://github.com/XRPLF/rippled/pull/5632))
|
||||
- **LendingProtocol**: Adds the ability to create loans on the XRP Ledger. Loan brokers can create fixed-term, uncollateralized loans using the pooled funds from a Single Asset Vault. The protocol is highly configurable, enabling loan brokers to tune risk appetite, depostitor protections, and economic incentives. ([#5632](https://github.com/XRPLF/rippled/pull/5632))
|
||||
- **fixBatchInnerSigs**: Fixes an issue where inner transactions of a `Batch` transaction would be flagged as having valid signatures. Inner transactions never have valid signatures. ([#6069](https://github.com/XRPLF/rippled/pull/6069))
|
||||
|
||||
|
||||
### Bug Fixes
|
||||
|
||||
- Expand `Number` to support full integer range. ([#6192](https://github.com/XRPLF/rippled/pull/6192))
|
||||
- Fix: Reorder Batch Preflight Errors. ([#6176](https://github.com/XRPLF/rippled/pull/6176))
|
||||
- Fix dependencies so clio can use libxrpl. ([#6251](https://github.com/XRPLF/rippled/pull/6251))
|
||||
- Fix: Remove DEFAULT fields that change to the default in associateAsset (was Add Vault creation tests for showing valid range for AssetsMaximum). ([#6259](https://github.com/XRPLF/rippled/pull/6259))

# Pseudo-Accounts
|
||||
|
||||
The XRP Ledger is an account-based blockchain where assets like XRP, trust line tokens, and Multi-Purpose Tokens (MPTs) are held by accounts, and are represented on-chain by an [AccountRoot](../../references/protocol/ledger-data/ledger-entry-types/accountroot) ledger entry. However, certain use cases require assets to be transferable to and from an object, which is why a pseudo-account is needed.
|
||||
|
||||
A pseudo-account is a special type of account that holds assets on behalf of an on-chain protocol. Use cases for pseudo-accounts include:
|
||||
|
||||
- **Automated Market Makers (AMM)**: The [XLS-30 amendment](../../../resources/known-amendments#amm) introduced pseudo-accounts for AMMs by adding the `AMMID` field to the `AccountRoot` ledger entry. This field links a pseudo-account to an AMM instance, allowing it to track XRP and token balances in the pool and issue `LPTokens` on behalf of the AMM instance.
|
||||
|
||||
- **Single Asset Vaults**: A single asset vault pseudo-account is used to store deposited funds and issue MPT shares. A new `VaultID` field is introduced in the `AccountRoot` ledger entry, which links the pseudo-account with the vault.
|
||||
|
||||
- **Lending Protocol**: The Lending Protocol also uses the single asset vault's pseudo-account, with each `LoanBroker` tracked in the pseudo-account's owner directory. The pseudo-account holds first-loss capital that protects vault depositors from loan defaults, as well as the loan funds themselves.
|
||||
|
||||
A pseudo-account has strict limitations. It cannot receive payments from other accounts, cannot send transactions since it has no signing authority, and exists solely to store or issue assets.
|
||||
|
||||
## Reserve Requirements
|
||||
|
||||
The cost of creating a pseudo-account depends on whether it is owned and controlled by another account:
|
||||
|
||||
- **Owned pseudo-accounts**: For objects like a `Vault` where a single account owns and controls the associated pseudo-account, the creation transaction increases the owner's XRP reserve by one [incremental owner reserve](../accounts/reserves#base-reserve-and-owner-reserve) (currently {% $env.PUBLIC_OWNER_RESERVE %}). This is in addition to any other reserve requirements of the transaction (for example, the Vault object itself).
|
||||
|
||||
- **Unowned pseudo-accounts**: For objects like an `AMM` that are not owned by any account, the creation transaction must charge a special, higher-than-normal transaction fee. This fee must be at least the value of one incremental owner reserve. This amount is burned, compensating for the permanent ledger space without tying the reserve to a specific owner.

# Lending Protocol
|
||||
|
||||
The Lending Protocol is an XRP Ledger DeFi primitive that enables on-chain, fixed-term, uncollateralized loans using pooled funds from a [Single Asset Vault](./single-asset-vaults.md). The protocol is highly configurable, enabling loan brokers to easily tune risk appetite, depostitor protections, and economic incentives.
|
||||
|
||||
The implementation relies on off-chain underwriting and risk management to assess the creditworthiness of borrowers, but offers peer-to-peer loans without intermediaries like banks or financial institutions. First-loss capital protection is used to help offset losses from loan defaults.
|
||||
|
||||
The current implementation of the lending protocol doesn't include automated on-chain collateral and liquidation management, instead focusing on on-chain credit origination.
|
||||
|
||||
To ensure compliance needs are met, asset issuers can [claw back](../../references/protocol/transactions/types/clawback.md) funds from the vault associated with the lending protocol. Issuers can also [freeze](./fungible-tokens/freezes.md) individual accounts or issue a global freeze.
|
||||
|
||||
{% amendment-disclaimer name="LendingProtocol" /%}
|
||||
|
||||
## Protocol Flow
|
||||
|
||||
There are three parties involved in the process of creating a loan:
|
||||
|
||||
- **Loan Brokers**: Create asset vaults and manage associated loans.
|
||||
- **Depositors**: Add assets to vaults.
|
||||
- **Borrowers**: Receive loans, making repayments as defined by their loan terms.
|
||||
|
||||
[{% inline-svg file="../../img/lending-protocol-diagram.svg" /%}](../../img/lending-protocol-diagram.svg "Diagram: The lifecycle of a loan.")
|
||||
|
||||
The lifecycle of a loan is as follows:
|
||||
|
||||
1. A loan broker creates a vault.
|
||||
2. Depositors add assets to the vault.
|
||||
3. (Optional) The loan broker deposits first-loss capital.
|
||||
4. A loan broker and borrower create a loan, defining the terms of the loan, and the requested principal (excluding fees) is transferred to the borrower.
|
||||
5. If payments are missed, the loan enters a grace period. Once the grace period expires, the loan broker has the option to default the loan.
|
||||
6. The loan is deleted when matured or defaulted.
|
||||
7. (Optional) The loan broker can withdraw first-loss capital.
|
||||
8. After all loans are paid, the loan broker can delete the `LoanBroker` ledger entry, and then the corresponding `Vault` ledger entry.
|
||||
|
||||
|
||||
## Accounting
|
||||
|
||||
### Risk Management
|
||||
|
||||
#### First-Loss Capital
|
||||
|
||||
First-Loss Capital is an optional mechanism to mitigate the risks associated with lending. To protect investors' assets, a loan broker can deposit assets as first-loss capital, which acts as a buffer in the event of loan defaults. The first-loss capital is placed into the vault to cover a percentage of losses from missed payments.
|
||||
|
||||
Three parameters control the First-Loss Capital:
|
||||
|
||||
- `CoverAvailable`: The total amount of cover deposited by the lending protocol owner.
|
||||
- `CoverRateMinimum`: The percentage of debt that must be covered by `CoverAvailable`.
|
||||
- `CoverRateLiquidation`: The maximum percentage of the minimum required cover _(DebtTotal x CoverRateMinimum)_ that will be placed in the asset vault to cover a loan default.
|
||||
|
||||
Whenever the available cover falls below the minimum required:
|
||||
|
||||
- The loan broker can't issue new loans.
|
||||
- The loan broker can't receive fees. All fees are added to the First-Loss Capital to cover the deficit.
|
||||
|
||||
Below is an example of how first-loss capital is used to cover a loan default:
|
||||
|
||||
```
|
||||
** Initial States **
|
||||

||||

||||

||||

|

|
||||
|
||||
DefaultAmount = PrincipleOutstanding + InterestOutstanding
|
||||
= 1,000 + 90
|
||||

|
||||
|
||||
# The amount of the default that the first-loss capital scheme will cover
|
||||
DefaultCovered = min((DebtTotal x CoverRateMinimum) x CoverRateLiquidation, DefaultAmount)
|
||||
= min((1,090 * 0.1) * 0.1, 1,090) = min(10.9, 1,090)
|
||||

|
||||
|
||||
Loss = DefaultAmount - DefaultCovered
|
||||

|
||||

|
||||
|
||||
FundsReturned = DefaultCovered
|
||||
= 10.9
|
||||
|
||||
# Note, Loss + FundsReturned MUST be equal to PrincipleOutstanding + InterestOutstanding
|
||||
|
||||
** State Changes **
|
||||
|
||||
-- Vault --
|
||||
AssetsTotal = AssetsTotal - Loss
|
||||
= 100,090 - 1,079.1
|
||||
= 99,010.9 Tokens
|
||||
|
||||
AssetsAvailable = AssetsAvailable + FundsReturned
|
||||
= 99,000 + 10.9
|
||||
= 99,010.9 Tokens
|
||||
|
||||
SharesTotal = (UNCHANGED)
|
||||
|
||||
-- Lending Protocol --
|
||||
DebtTotal = DebtTotal - PrincipleOutstanding + InterestOutstanding
|
||||
= 1,090 - (1,000 + 90)
|
||||

|
||||
|
||||
CoverAvailable = CoverAvailable - DefaultCovered
|
||||
= 1,000 - 10.9
|
||||
= 989.1 Tokens
|
||||
```
|
||||
|
||||
#### Impairment
|
||||
|
||||
If the loan broker discovers a borrower can't make an upcoming payment, impairment allows the loan broker to register a "paper loss" with the vault. The impairment mechanism moves the due date of the next payment to the time the loan is impaired, allowing the loan to default more quickly. However, if the borrower makes a payment before that date, the impairment status is automatically cleared.
|
||||
|
||||
|
||||
### Compliance
|
||||
|
||||
#### Clawback
|
||||
|
||||
Issuers (trust line token or MPT, not XRP) can claw back funds from First-Loss Capital. To ensure there is always a minimum amount of capital available to protect depositors, issuers can't claw back the entire available amount. Instead, they can claw back up to a minimum amount of First-Loss Capital that the loan broker must maintain for the lending protocol; the minimum amount is calculated as `LoanBroker.DebtTotal * LoanBroker.CoverRateMinimum`.
|
||||
|
||||
#### Freeze
|
||||
|
||||
Freezing is a mechanism by which an asset issuer (trust line token or MPT, not XRP) prevents an account from sending their issued asset. _Deep freeze_ takes this a step further by preventing an account from sending _and_ receiving issued assets. Issuers can also enact a _global freeze_, which prevents everyone from sending or receiving their issued asset.
|
||||
|
||||
{% admonition type="info" name="Note" %}
|
||||
In all freeze scenarios, assets can be sent back to the issuer.
|
||||
{% /admonition %}
|
||||
|
||||
If a borrower has their account frozen or deep frozen, they can't make loan payments. This doesn't absolve a borrower of their repayment obligations, and they will eventually default on their loan.
|
||||
|
||||
Freezing a borrower's account won't affect a loan broker's functions, but it will prevent them from receiving any lending protocol fees. However, issuers can freeze a loan broker's _pseudo-account_ and prevent the loan broker from creating new loans; existing loans won't be affected. A deep freeze on a loan broker's _pseudo-account_ also prevents loans from being repaid.
|
||||
|
||||
|
||||
### Interest Rates
|
||||
|
||||
There are three interest rates associated with a loan:
|
||||
|
||||
- **Interest Rate**: The regular interest rate based on the principal amount. It is the cost of borrowing funds.
|
||||
- **Late Interest Rate**: A higher interest rate charged for a late payment.
|
||||
- **Full Payment Rate**: An interest rate charged for repaying the total loan early.
|
||||
|
||||
|
||||
### Fees
|
||||
|
||||
The lending protocol charges a number of fees that the loan broker can configure. The protocol won't charge these fees if the loan broker hasn't deposited enough first-loss capital.
|
||||
|
||||
- **Management Fee**: This is a percentage of interest charged by the loan broker. Vault depositors pay this fee.
|
||||
- **Loan Origination Fee**: A fee paid to the loan broker, taken from the principal amount loaned out.
|
||||
- **Loan Service Fee**: A fee charged on top of each loan payment.
|
||||
- **Late Payment Fee**: A fee paid on top of a late payment.
|
||||
- **Early Payment Fee**: A fee paid on top of an early payment.
|
||||
|
||||
|
||||
## Loan Payment Processing
|
||||
|
||||
Loan payments are evaluated and processed around three criteria: amount, timing, and specified flags. The combination of these criteria determine how funds are applied to the loan's principal, interest, and associated fees.
|
||||
|
||||
Each payment consists of four components:
|
||||
|
||||
- **Principal**: The portion that reduces the outstanding loan principle.
|
||||
- **Interest**: The portion that covers the cost of borrowing for the period.
|
||||
- **Fees**: The portion that covers any applicable service fees, management fees, late payment fees, or other charges.
|
||||
- **ValueChange**: The amount by which the payment changes the loan balance.
|
||||
|
||||
When the loan payment is submitted, the lending protocol then checks these parameters:
|
||||
|
||||
- **Timing**: Is the payment on time or late?
|
||||
- **Amount**: Does the payment amount meet the minimum required amount, or exceed it?
|
||||
|
||||
Based on the timing and transaction flags, the lending protocol processes the payment as one of four types:
|
||||
|
||||
- **On-Time Payments**: If the payment is on-time, it's further classified into these payment scenarios:
|
||||
- **Sequential Periodic Payments**: The payment is applied to as many complete payment cycles as possible; cycles are calculated as the amount due each payment period (including fees).
|
||||
- **Overpayments**: After all possible cycles are fully paid, any remaining amount is treated as an overpayment and applied to the principal. This type of payment requires the `lsfLoanOverpayment` flag to be enabled on the `Loan` ledger entry, as well as the `tfLoanOverpayment` flag to be enabled on the `LoanPay` transaction. If these flags are missing, the excess amount is ignored.
|
||||
- **Full Early Repayment**: The payment has the `tfLoanFullPayment` flag set, and the amount covers the remainder of the loan (including fees).
|
||||
- **Late Payments**: The payment is late on a payment cycle. Late payments must be for an exact amount, calculated as:
|
||||
|
||||
`totalDue = periodicPayment + loanServiceFee + latePaymentFee + latePaymentInterest`
|
||||
|
||||
Overpayments aren't permitted on late payments; any excess amount is ignored.
|
||||
|
||||
{% admonition type="info" name="Note" %}
|
||||
In scenarios where excess payment amounts are "ignored", the transaction succeeds, but the borrower is only charged on the expected amount.

# Single Asset Vaults
|
||||
|
||||
A single asset vault is an XRP Ledger primitive that aggregates assets from multiple depositors and makes them available to other on-chain protocols, such as the Lending Protocol. A vault asset can be [XRP](../../introduction/what-is-xrp.md), a [trust line token](../tokens/fungible-tokens/index.md), or an [MPT (Multi-Purpose Token)](../tokens/fungible-tokens/multi-purpose-tokens.md).
|
||||
|
||||
A Vault Owner account manages the vault and can create, update, or delete it as needed. When creating a vault, the Vault Owner can also specify whether shares are transferable or non-transferable. Non-transferable shares cannot be transferred to any other account, and can only be redeemed.

## Public vs. Private Vaults
|
||||
|
||||
A vault can be **public** or **private**, depending on the required level of access control.
|
||||
|
||||
In a public vault, anyone can deposit or redeem liquidity as long as they hold sufficient shares. In contrast, a private vault restricts access, allowing only depositors with the necessary [Credentials](../../concepts/decentralized-storage/credentials.md), managed through [Permissioned Domains](./decentralized-exchange/permissioned-domains.md), to deposit assets.
|
||||
|
||||
{% admonition type="warning" name="Warning" %}
|
||||
If a depositor's credentials expire, they can no longer deposit assets in a private vault, but can always redeem their existing shares.
|
||||
{% /admonition %}
|
||||
|
||||
To prevent the Vault Owner from locking funds away, any shareholder in a private vault can redeem their shares for assets.
|
||||
|
||||
Choosing between a public or private vault depends on your use case. For example, if depositor identity verification is required, use a private vault and issue credentials only to verified accounts.
|
||||
|
||||
## Vault Share Distribution and Redemption
|
||||
|
||||
Depositors can deposit assets to receive shares, which represent their proportional ownership of the vault, or redeem shares for assets.
|
||||
|
||||
[{% inline-svg file="../../img/single-asset-vault-img.svg" /%}](../../img/single-asset-vault-img.svg "Diagram: an example of an asset being deposited into the vault and shares being redeemed.")
|
||||
|
||||
Since the XRP Ledger is an account-based blockchain, all assets must be held by an account. A `Vault` ledger entry cannot hold assets directly, so a [pseudo-account](../accounts/pseudo-accounts.md) is created to hold assets on its behalf. This stand-alone account cannot receive funds or send transactions, and exists solely to store assets and issue shares.
|
||||
|
||||
Each share is represented on-chain as an MPT, issued by the vault's pseudo-account. Since MPTs can only exist as whole number units, the vault uses a `Scale` setting to convert fractional asset amounts into whole number shares.
|
||||
|
||||
The scale behavior varies based on the type of asset held by the vault:
|
||||
|
||||
- **XRP**: Uses a fixed scale that aligns with XRP's native structure, where one share represents one drop.
|
||||
- **Trust Line Token**: Allows configurable precision (default preserves 6 decimal places).
|
||||
- **MPT**: Uses a 1-to-1 relationship between MPT units and shares.
|
||||
|
||||
Depending on the connected protocol, vault shares may be yield-bearing, meaning shareholders could redeem shares for more or less liquidity than they originally deposited. This is because the total asset balance in the vault can grow or shrink over time, affecting the value of each share. However, the vault asset (e.g., USDC, XRP) does not generate yield on its own.
|
||||
|
||||
The value of each share depends on the total assets in the vault:
|
||||
|
||||
- If the vault earns yield over time, shares represent a larger claim, allowing depositors to redeem them for more assets.
|
||||
- If the vault incurs losses, shares hold less value, resulting in lower redemptions.
|
||||
|
||||
A vault could generate yield through mechanisms like lending or staking, with yield paid in the same asset deposited. The specific logic for this depends on how the connected on-chain protocol generates yield. For example, if a vault is used by a lending protocol, it could earn yield from interest paid by borrowers.
|
||||
|
||||
### Exchange Algorithm
|
||||
|
||||
A single asset vault uses an **exchange algorithm** to define how assets convert into shares during deposits and how shares convert back into assets during redemptions.
|
||||
|
||||
A vault's total value can fluctuate due to factors like _unrealized losses_, which impact the exchange rate for deposits and redemptions. To ensure fairness, the algorithm adjusts the exchange rate dynamically, so depositors receive shares or redeem them for assets at a rate that accurately reflects the vault’s true value.
|
||||
|
||||
#### Unrealized Loss
|
||||
|
||||
To prevent depositors from exploiting potential losses by redeeming shares early and shifting the full loss onto the remaining depositors, the vault tracks unrealized losses (or paper loss) using the `LossUnrealized` attribute in the `Vault` ledger entry.
|
||||
|
||||
Because the unrealized loss temporarily decreases the vault's value, a malicious depositor may take advantage of this by depositing assets at a lowered price and redeeming shares once the price increases.
|
||||
|
||||
For example, consider a vault with a total value of $1.0m and total shares of 1.0m. Let's assume the unrealized loss for the vault is $900k:
|
||||
|
||||
1. The new exchange rate is calculated as:
|
||||
|
||||
```js
|
||||
// ExchangeRate = (AssetsTotal - LossUnrealized) / SharesTotal
|
||||
exchangeRate = (1,000,000 - 900,000) / 1,000,000
|
||||
```
|
||||
|
||||
The exchange rate value is now **0.1**.
|
||||
|
||||
2. After the unrealized loss is cleared, the new effective exchange rate would be:
|
||||
|
||||
```js
|
||||
// ExchangeRate = AssetsTotal / SharesTotal
|
||||
exchangeRate = 1,000,000 / 1,000,000
|
||||
```
|
||||
|
||||
The exchange rate is now **1.0**.
|
||||
|
||||
A depositor could deposit $100k assets at a 0.1 exchange rate and get 1.0m shares. Once the unrealized loss is cleared, their shares would be worth $1.0m.
|
||||
|
||||
To mitigate this, the vault uses separate exchange rates for deposits and redemptions.
|
||||
|
||||
#### Exchange Rates
|
||||
|
||||
A single asset vault uses **two distinct exchange rates**:
|
||||
|
||||
- **Deposit Exchange Rate**: Protects new depositors from prior losses and ensures fair share allocation.
|
||||
- **Withdrawal Exchange Rate**: Ensures all shareholders share losses proportionally. Whether redeeming shares or withdrawing assets, the vault always calculates payouts using the actual current value (total assets minus losses), so depositors get their fair share of what's actually in the vault.
|
||||
- **Redemptions**: The vault burns shares so the depositor can receive proportional assets.
|
||||
- **Withdrawals**: The vault determines the shares to burn based on the requested asset amount.
|
||||
|
||||
These exchange rates ensure fairness and prevent manipulation, maintaining the integrity of deposits and redemptions.
|
||||
|
||||
To understand how the exchange rates are applied, here are the key variables used in the calculations:
|
||||
|
||||
- `Γ_assets`: The total balance of assets held within the vault.
|
||||
- `Γ_shares`: The total number of shares currently issued by the vault.
|
||||
- `Δ_assets`: The amount of assets being deposited, withdrawn, or redeemed.
|
||||
- `Δ_shares`: The number of shares being issued or burned.
|
||||
- `l`: The vault's total unrealized loss.
|
||||
- `σ`: The scaling factor (σ = 10<sup>Scale</sup>) used to convert fractional assets into whole number shares.
|
||||
|
||||
{% tabs %}
|
||||
{% tab label="Deposit" %}
|
||||
The vault computes the number of shares a depositor will receive as follows:
|
||||
|
||||
- **Initial Deposit (Empty Vault)**: For the first deposit into an empty vault, shares are calculated using the scaling factor to properly represent fractional assets as whole numbers.
|
||||
|
||||
```js
|
||||
Δ_shares = Δ_assets * σ // σ = 10^Scale
|
||||
```
|
||||
|
||||
- **Subsequent Deposits**: For all other deposits, shares are calculated proportionally. The resulting share value is rounded **down** to the nearest whole number.
|
||||
|
||||
```js
|
||||
Δ_shares = (Δ_assets * Γ_shares) / Γ_assets
|
||||
```
|
||||
Because the share amount is rounded down, the actual assets taken from the depositor are recalculated. This ensures the depositor isn't overcharged and that new shares are valued against the vault's true value, accounting for any unrealized loss:
|
||||
|
||||
```js
|
||||
Δ_assets = (Δ_shares * (Γ_assets - l)) / Γ_shares
|
||||
```
|
||||
|
||||
After a successful deposit, the _total assets_ and _total shares_ values are updated like so:
|
||||
|
||||
```js
|
||||
Γ_assets = Γ_assets + Δ_assets // New balance of assets in the vault.
|
||||
Γ_shares = Γ_shares + Δ_shares // New share balance in the vault.
|
||||
```
|
||||
{% /tab %}
|
||||
|
||||
{% tab label="Redeem" %}
|
||||
The vault computes the number of assets returned by burning shares as follows:
|
||||
|
||||
```js
|
||||
Δ_assets = (Δ_shares * (Γ_assets - l)) / Γ_shares
|
||||
```
|
||||
|
||||
After a successful redemption, the _total assets_ and _total shares_ values are updated like so:
|
||||
|
||||
```js
|
||||
Γ_assets = Γ_assets - Δ_assets // New balance of assets in the vault.
|
||||
Γ_shares = Γ_shares - Δ_shares // New share balance in the vault.
|
||||
```
|
||||
|
||||
{% /tab %}
|
||||
|
||||
{% tab label="Withdraw" %}
|
||||
When a depositor requests a specific asset amount, the vault uses a two-step process to determine the final payout:
|
||||
|
||||
1. The requested asset amount (`Δ_assets_requested`) is converted into shares.
|
||||
|
||||
```js
|
||||
Δ_shares = (Δ_assets_requested * Γ_shares) / (Γ_assets - l)
|
||||
```
|
||||
|
||||
The calculated share amount is rounded to the **nearest** whole number.
|
||||
|
||||
2. The rounded number of shares is used to calculate the final asset payout (`Δ_assets_out`), using the same logic as a redemption.
|
||||
|
||||
```js
|
||||
Δ_assets_out = (Δ_shares * (Γ_assets - l)) / Γ_shares
|
||||
```
|
||||
|
||||
Due to rounding in step 1, the final payout may differ slightly from the requested amount.
|
||||
|
||||
After a successful withdrawal, the _total asset_ and _total share_ values are updated like so:
|
||||
|
||||
```js
|
||||
Γ_assets = Γ_assets - Δ_assets_out // New balance of assets in the vault.
|
||||
Γ_shares = Γ_shares - Δ_shares // New share balance in the vault.
|
||||
```

### Can a Depositor Transfer Shares to Another Account?
|
||||
|
||||
Vault shares are a first-class asset, meaning that they can be transferred and used in other on-ledger protocols that support MPTs. However, the payee (or the receiver) must have permission to hold both the shares and the underlying asset.
|
||||
|
||||
For example, if a private vault holds USDC, the destination account must belong to the vault’s Permissioned Domain and have permission to hold USDC. Any compliance mechanisms applied to USDC also apply to the shares. If the USDC issuer freezes the payee’s trust line, the payee cannot receive shares representing USDC.
|
||||
|
||||
{% admonition type="info" name="Note" %}
|
||||
It is important to remember that a vault must be **configured** to allow share transfers, or this will not be possible.
|
||||
{% /admonition %}
|
||||
|
||||
A depositor can transfer vault shares to another account by making a [Payment](../../references/protocol/transactions/types/payment) transaction. Nothing changes in the way the payment transaction is submitted for transferring vault shares. However, there are new failure scenarios to watch out for if the transaction fails:
|
||||
|
||||
- The vault is private and the payee lacks credentials in the vault's permissioned domain.
|
||||
- The vault shares are configured as non-transferable.
|
||||
- There is a global freeze (trust line tokens) or lock (MPTs) on the underlying asset.
|
||||
- The underlying asset is an MPT and is locked for the payer, payee, or vault pseudo-account.
|
||||
- The underlying asset is a trust line token and the trust line is frozen between the issuer and the payer, payee, or vault pseudo-account.
|
||||
|
||||
If the transfer succeeds and the payee already holds vault shares, their balance increases. Otherwise, a new MPT entry is created for their account.
|
||||
|
||||
## Compliance
|
||||
|
||||
### Frozen Assets
|
||||
|
||||
The issuer of a vault asset can enact a [freeze](./fungible-tokens/freezes) for trust line tokens or [lock an MPT](./fungible-tokens/deep-freeze#how-does-mpt-freeze/lock-behavior-differ-from-iou). When a vault asset is frozen:
|
||||
|
||||
1. Withdrawals can only be made to the asset’s issuer.
|
||||
2. The asset cannot be deposited into the vault.
|
||||
3. Its corresponding shares also cannot be transferred.
|
||||
|
||||
### Clawback
|
||||
|
||||
An asset issuer can perform a [Clawback](../../use-cases/tokenization/stablecoin-issuer#clawback) on vault assets by forcing redemption of shares held by an account. This exchanges the holder's shares for the underlying assets, which are sent directly to the issuer. This mechanism allows asset issuers to recover their issued assets from vault depositors when necessary for fraud prevention or regulatory compliance.
|
||||
|
||||
## Why Use a Single Asset Vault?
|
||||
|
||||
With a single asset vault you don't have to manage liquidity at the protocol level. Instead, you can use the vault to handle deposits, redemptions, and asset tracking separately.
|
||||
|
||||
Vaults handle asset-to-share conversion, ensure accurate pricing, and eliminate the need to add custom logic to calculate exchange rates or account for unrealized losses.
|
||||
|
||||
Depending on the connected on-chain protocol, vaults can be applied to various use cases, such as:
|
||||
|
||||
- Lending markets
|
||||
- Aggregators
|
||||
- Yield-bearing tokens
|
||||
- Asset management
|
||||
|
||||
The only supported use cases right now are _asset management_ and [_lending markets_](./lending-protocol.md).

The response follows the [standard format][], with a successful result containing the following fields:
|
||||
|
||||
| Field | Type | Description |
|
||||
| :--------------------- | :--------------- | :---------- |
|
||||
| `ledger_hash` | [Hash][] | _(Omitted if either `ledger_current_index` or `ledger_index` is provided instead)_ The identifying hash of the ledger version that was used when retrieving this data. |
|
||||
| `ledger_current_index` | [Ledger Index][] | _(Omitted if `ledger_index` is provided instead)_ The [ledger index][] of the current in-progress ledger, which was used when retrieving this information. |
|
||||
| `ledger_index` | [Ledger Index][] | _(Omitted if `ledger_current_index` is provided instead)_ The [ledger index][] of the ledger version used when retrieving this information. |
|
||||
| `validated` | Boolean | True if this data is from a validated ledger version; if omitted or set to false, this data is not final. |
|
||||
| `vault` | Object | The [**Vault Description Object**](#vault-description-object) that represents the current status of the vault. |
|
||||
|
||||
### Vault Description Object
|
||||
|
||||
The `vault` field is an object describing the current status of a `Vault` entry in the ledger, and contains the following fields:
|
||||
|
||||
| `Field` | Type | Description |
|
||||
| :--------------------- | :------------------- | :---------- |
|
||||
| `Account` | String - [Address][] | The address of the vault's pseudo-account. |
|
||||
| `Asset` | Object | The [**Asset**](#asset-object) of the vault. An asset can be XRP, a trust line token, or an MPT. |
|
||||
| `AssetsAvailable` | Number | The asset amount that is available in the vault. |
|
||||
| `AssetsMaximum` | Number | The maximum asset amount that can be held in the vault. If set to 0, this indicates there is no cap. |
|
||||
| `AssetsTotal` | Number | The total value of the vault. |
|
||||
| `Flags` | String | Set of bit-flags for this ledger object. |
|
||||
| `LossUnrealized` | Number | The potential loss amount that is not yet realized, expressed as the vault's asset. |
|
||||
| `ShareMPTID` | String | The identifier of the share `MPTokenIssuance` object. |
|

|
||||
| `shares` | Object | A [**Shares Object**](#shares-object) containing details about the vault's issued shares. |
|
||||
| `Scale` | Number | Specifies decimal precision for share calculations. Assets are multiplied by 10<sup>Scale</sup > to convert fractional amounts into whole number shares. For example, with a `Scale` of `6`, depositing 20.3 units creates 20,300,000 shares (20.3 × 10<sup>Scale</sup >). For **trust line tokens** this can be configured at vault creation, and valid values are between 0-18, with the default being `6`. For **XRP** and **MPTs**, this is fixed at `0`. |
|
||||
|
||||
### Asset Object

A `Loan` ledger entry defines the state of an on-chain loan agreement between a _Loan Broker_ and a _Borrower_. It contains all the details of the loan, such as fees and interest rates. You can create a `Loan` ledger entry with the [LoanSet transaction][].
|
||||
|

The `Loan` ledger entry is tracked in two [Owner Directories](./directorynode.md):
|
||||
1. The owner directory of the _Borrower_ on the loan.
|
||||
2. The owner directory of the `LoanBroker` pseudo-account.

When the loan broker discovers that the borrower can't make an upcoming payment, they can impair the loan to register a "paper loss" with the vault. The impairment mechanism moves up the `NextPaymentDueDate` to the time the loan is impaired, allowing the loan to default quicker. However, if the borrower makes a payment in the subsequent `GracePeriod`, the impairment status is removed.

A {% code-page-name /%} object defines the state of a tokenized vault. It contains key details such as available assets, shares, total value, and other relevant information. You can create a {% code-page-name /%} object with the [VaultCreate](../../transactions/types/vaultcreate.md) transaction.
|
||||
|
||||
The {% code-page-name /%} object is tracked in an [Owner Directory](../../../protocol/ledger-data/ledger-entry-types/directorynode) owned by the Vault Owner account.
|
||||
Additionally, to facilitate `Vault` object lookup, the object is tracked in the owner directory of the vault's [pseudo-account](../../../../concepts/accounts/pseudo-accounts.md).

## {% $frontmatter.seo.title %} Fields
|
||||
|
||||
In addition to the [common ledger entry fields](../../../protocol/ledger-data/common-fields), {% code-page-name /%} entries have the following fields:
|
||||
|
||||
| Name | JSON Type | [Internal Type][] | Required? | Description |
|
||||
| :------------------ | :------------ | :---------------- | :-------- | -----------------|
|
||||
| `PreviousTxnID` | String | Hash256 | Yes | Identifies the transaction ID that most recently modified this object. |
|
||||
| `PreviousTxnLgrSeq` | Number | UInt32 | Yes | The sequence of the ledger that contains the transaction that most recently modified this object. |
|
||||
| `Sequence` | Number | UInt32 | Yes | The transaction sequence number that created the vault. |
|
||||
| `OwnerNode` | Number | UInt64 | Yes | Identifies the page where this item is referenced in the owner's directory. |
|
||||
| `Owner` | String | AccountID | Yes | The account address of the Vault Owner. |
|
||||
| `Account` | String | AccountID | Yes | The address of the vault's pseudo-account. |
|
||||
| `Data` | String | Blob | No | Arbitrary metadata, in hex format, about the vault. Limited to 256 bytes. See [Data Field Format](#data-field-format) for more information. |
|
||||
| `Asset` | Object | Issue | Yes | The asset of the vault. The vault supports XRP, trust line tokens, and MPTs. |
|
||||
| `AssetsTotal` | Number | Number | Yes | The total value of the vault. |
|
||||
| `AssetsAvailable` | Number | Number | Yes | The asset amount that is available in the vault. |
|
||||
| `AssetsMaximum` | Number | Number | No | The maximum asset amount that can be held in the vault. If set to 0, this indicates there is no cap. |
|
||||
| `LossUnrealized` | Number | Number | Yes | The potential loss amount that is not yet realized, expressed as the vault's asset. Only a protocol connected to the vault can modify this attribute. |
|
||||
| `ShareMPTID` | String | UInt192 | Yes | The identifier of the share `MPTokenIssuance` object. |
|
||||
| `WithdrawalPolicy` | String | UInt8 | Yes | Indicates the withdrawal strategy used by the vault. |
|
||||
| `Scale` | Number | UInt8 | No | Specifies decimal precision for share calculations. Assets are multiplied by 10<sup>Scale</sup > to convert fractional amounts into whole number shares. For example, with a `Scale` of `6`, depositing 20.3 units creates 20,300,000 shares (20.3 × 10<sup>Scale</sup >). For **trust line tokens** this can be configured at vault creation, and valid values are between 0-18, with the default being `6`. For **XRP** and **MPTs**, this is fixed at `0`. See [Scaling Factor](#scaling-factor) for more information. |
|
||||
|
||||
### Data Field Format
|
||||
|
||||
While any data structure is allowed in the `Data` field, the following format is recommended:
|
||||
|
||||
| Field Name | Key | Type | Description |
|
||||
| ---------- | --- | ------ | ------------------------------------------------------------------------------------------ |
|
||||
| Name | n | String | Human-readable name of the vault. Should clearly reflect the vault's strategy or mandate. |
|
||||
| Website | w | String | Website associated with the vault. Omit protocol (`https://`) and `www` to conserve space. |
|
||||
|
||||
To fit within the 256-byte limit, vault metadata should use the _compressed_ JSON keys.
|
||||
|
||||
Following this format helps XRPL explorers and other tools parse and display vault information in a standardized way, improving discoverability and user experience.
|
||||
|
||||
#### Example JSON
|
||||
|
||||
For a vault named "LATAM Fund II" with website "examplefund.com":
|
||||
|
||||
```json
|
||||
{
|
||||
"n": "LATAM Fund II",
|
||||
"w": "examplefund.com"
|
||||
}
|
||||
```
|
||||
|
||||
1. Remove any whitespace from the JSON:
|
||||
|
||||
`{"n":"LATAM Fund II","w":"examplefund.com"}`
|
||||
|
||||
2. Hex-encode the JSON. For example:
|
||||
|
||||
```sh
|
||||
# Using xxd (macOS/Linux)
|
||||
echo -n '{"n":"LATAM Fund II","w":"examplefund.com"}' | xxd -p | tr -d '\n'
|
||||
```
|
||||
|
||||
You should see this result: `7b226e223a224c4154414d2046756e64204949222c2277223a226578616d706c6566756e642e636f6d227d`
|
||||
|
||||
### Scaling Factor
|
||||
|
||||
The **`Scale`** field enables the vault to accurately represent fractional asset values using integer-only MPT shares, which prevents the loss of value from decimal truncation. It defines a scaling factor, calculated as 10<sup>Scale</sup>, that converts a decimal asset amount into a corresponding whole number of shares.
|
||||
|
||||
The scaling factor behavior varies by asset type:
|
||||
|
||||
- **Trust line token**: When a vault holds a trust line token, the `Scale` is configurable by the Vault Owner when creating the vault. The value can range from **0** to a maximum of **18**, with a default of **6**. This flexibility allows issuers to set a level of precision appropriate for their specific token.
|
||||
|
||||
- **XRP**: When a vault holds XRP, the `Scale` is fixed at **0**. This aligns with XRP's native structure, where one share represents one drop, and one XRP equals 1,000,000 drops. Therefore, a deposit of 10 XRP to an empty vault will result in the issuance of 10,000,000 shares.
|
||||
|
||||
- **MPT**: When a vault holds an MPT, its `Scale` is fixed at **0**. This creates a 1-to-1 relationship between deposited MPT units and the shares issued. For example, depositing 10 MPTs to an empty vault issues 10 shares. The value of a single MPT is determined at the issuer's discretion.
|
||||
|
||||
{% admonition type="warning" name="Warning" %}
|
||||
If an MPT is set to represent a large value, the vault owner and the depositor must be cautious. Since only whole MPT units are used in calculations, any value that is not a multiple of a single MPT's value may be lost due to rounding during a transaction.

## {% $frontmatter.seo.title %} Flags
|
||||
|

{% code-page-name /%} entries can have the following flags:

|
||||
| Flag Name | Flag Value | Description |
|

| `lsfVaultPrivate` | `0x00010000` | If set, indicates that the vault is private. This flag can only be set when _creating_ the vault. |
|
||||
|
||||
## Vault ID Format
|
||||
|
||||
The ID of a {% code-page-name /%} entry is the [SHA-512Half][] of the following values, concatenated in order:
|
||||
|
||||
- The {% code-page-name /%} space key `0x0056` (capital V).
|
||||
- The [AccountID](../../../protocol/binary-format/#accountid-fields) of the account submitting the transaction (for example, the vault owner).
|
||||
- The transaction `Sequence` number. If the transaction used a [Ticket](../../../../concepts/accounts/tickets), use the `TicketSequence` value.
