# Checks

_(Added by the [Checks amendment][].)_

The Checks feature in the XRP Ledger allows users to create deferred payments that can be canceled or cashed by the intended recipients. Like personal paper checks, XRP Ledger Checks start with the sender of the funds creating a Check that specifies an amount and a recipient. The recipient cashes the check to pull the funds from the sender's account into the recipient's account. No money moves until the recipient cashes the Check. Because funds are not put on hold when the Check is created, cashing a Check can fail if the sender doesn't have enough funds when the recipient tries to cash it. If there's a failure cashing the check, the check's recipient can retry until the Check expires.

XRP Ledger Checks may have expiration times after which they may no longer be cashed. If the recipient doesn't successfully cash the Check before it expires, the Check can no longer be cashed, but the object remains in the XRP Ledger until someone cancels it. Anyone may cancel the Check after it expires. Only the sender and recipient can cancel the Check before it expires. The Check object is removed from the Ledger when the sender successfully cashes the check or someone cancels it.

Checks have some similarities to [Escrow](escrow.html) and [Payment Channels](use-payment-channels.html), but there are some important differences between those features and Checks:

* You can send [tokens](tokens.html) with Checks. With Payment Channels and Escrow, you can only send XRP.

* Checks do not lock up or set aside any funds. The XRP involved in Payment Channels and Escrow cannot be spent until it is redeemed with a claim provided by the sender (Payment Channels), or released by an expiration or crypto-condition (Escrow).

* You can send XRP to yourself through Escrow. You cannot send Checks to yourself.


**Note:** The [Checks amendment][] changes the expiration behavior of the [OfferCreate][] transaction. For more information, see [Offer Expiration](offers.html#offer-expiration).


## Why Checks?

Traditional paper checks allow people to transfer funds without immediately exchanging physical currency. XRP Ledger Checks allow people to exchange funds asynchronously using a process that is familiar to and accepted by the banking industry.

XRP Ledger Checks also solve a problem that is unique to the XRP Ledger: they allow users to reject unwanted payments or accept only part of a payment. This is useful for institutions that need to be careful about accepting payments for compliance reasons.


### Use Case: Payment Authorization

**Problem:** To comply with regulations like [BSA, KYC, AML, and CFT](become-an-xrp-ledger-gateway.html#gateway-compliance), financial institutions must provide documentation about the source of funds they receive. Such regulations seek to prevent the illicit transfer of funds by requiring institutions to know the source and destination of all payments processed by the institution. Because of the nature of the XRP Ledger, anyone could potentially send XRP (and, under the right circumstances, tokens) to an institution's account on the XRP Ledger. Dealing with such unwanted payments adds significant cost and time delays to these institutions' compliance departments, including potential fines or penalties. <!-- SPELLING_IGNORE: cft -->

**Solution:** Institutions can enable [Deposit Authorization](depositauth.html) on their XRP Ledger accounts by [setting the `asfDepositAuth` flag in an `AccountSet` transaction](accountset.html). This makes the account unable to receive Payment transactions. Accounts with Deposit Authorization enabled can only receive funds through Escrow, Payment Channels, or Checks. Checks are the most straightforward, familiar, and flexible way to transfer funds if Deposit Authorization is enabled.


## Usage

Checks typically have the lifecycle described below.

**Step 1:** To create a Check, the sender submits a [CheckCreate][] transaction and specifies the recipient (`Destination`), expiration time (`Expiration`), and maximum amount that may be debited from the sender's account (`SendMax`).


**Step 2:** After the CheckCreate transaction is processed, a [Check object](check.html) is created on the XRP Ledger. This object contains the properties of the Check as defined by the transaction that created it. The object can only be modified by the sender (by canceling it with a [CheckCancel][] transaction) or recipient (by canceling it or cashing it) before the expiration time passes. After the expiration time, anyone may cancel the Check.

**Step 3:** To cash the check, the recipient submits a [CheckCash][] transaction. The recipient has two options for cashing the check:

* `Amount` — The recipient can use this option to specify an exact amount to cash. This may be useful for cases where the sender has padded the check to cover possible [transfer fees](transfer-fees.html) and the recipient wants to accept the exact amount on an invoice or other contract.

* `DeliverMin` — The recipient can use this option to specify the minimum amount they are willing to receive from the Check. If the recipient uses this option, the XRP Ledger attempts to deliver as much as possible and always delivers at least this amount. The transaction fails if the amount that can be credited to the recipient is not at least the requested amount.

If the sender has enough funds to cover the Check and the expiration time has not passed, the funds are debited from the sender's account and credited to the recipient's account, and the Check object is destroyed.



#### Expiration Case

In the case of expirations, Checks have the lifecycle described below.

[![Check flow diagram (expiration)](img/checks-expiration.png)](img/checks-expiration.png)


All Checks start the same way, so **Steps 1 and 2** are the same.

**Step 3a:** If the Check expires before the recipient can cash it, the Check can no longer be cashed but the object remains in the ledger.

**Step 4a:** After a Check expires, anyone may cancel it by submitting a [CheckCancel][] transaction. That transaction removes the Check from the ledger.
