 # ripple-lib Release History
 
+Subscribe to [the **ripple-lib-announce** mailing list](https://groups.google.com/forum/#!forum/ripple-lib-announce) for release announcements. We recommend that ripple-lib users stay up-to-date with the latest stable release.
+
+## 1.9.3 (2021-03-16)
+
+* Expose ripple-address-codec methods. These are static methods on RippleAPI, so you do not need to create a RippleAPI instance.
+  * `classicAddressToXAddress` / `xAddressToClassicAddress`
+  * `isValidXAddress` / `isValidClassicAddress`
+  * `encodeSeed` / `decodeSeed`
+  * `encodeAccountID` / `decodeAccountID`
+  * `encodeNodePublic` / `decodeNodePublic`
+  * `encodeAccountPublic` / `decodeAccountPublic`
+  * `encodeXAddress` / `decodeXAddress`
+
+Example 1. Encode an X-address with tag 4294967295:
+```js
+const RippleAPI = require('ripple-lib').RippleAPI
+const xAddress = RippleAPI.classicAddressToXAddress('rGWrZyQqhTp9Xu7G5Pkayo7bXjH4k4QYpf', 4294967295)
+console.log(xAddress)
+```
+
+Output for Example 1:
+```
+XVLhHMPHU98es4dbozjVtdWzVrDjtV18pX8yuPT7y4xaEHi
+```
+
+Example 2. Encode a test address for use with Testnet or Devnet:
+```js
+const RippleAPI = require('ripple-lib').RippleAPI
+const address = RippleAPI.classicAddressToXAddress('r3SVzk8ApofDJuVBPKdmbbLjWGCCXpBQ2g', 123, true)
+console.log(address)
+```
+
+Output for Example 2:
+```
+T7oKJ3q7s94kDH6tpkBowhetT1JKfcfdSCmAXbS75iATyLD
+```
+
+Example 3. Decode an X-address:
+```js
+const RippleAPI = require('ripple-lib').RippleAPI
+const address = RippleAPI.xAddressToClassicAddress('XVLhHMPHU98es4dbozjVtdWzVrDjtV18pX8yuPT7y4xaEHi')
+console.log(address)
+```
+
+Output for Example 3:
+```js
+{
+  classicAddress: 'rGWrZyQqhTp9Xu7G5Pkayo7bXjH4k4QYpf',
+  tag: 4294967295,
+  test: false
+}
+```

+
+An *address* refers to a specific XRP Ledger account. It is a base-58 encoding of a hash of the account's public key. There are two kinds of addresses in common use:
+
+### Classic Address
+
+A *classic address* encodes a hash of the account's public key and a checksum. It has no other data. This kind of address always starts with the lowercase letter `r`.
+
+### X-address
+
+An *X-address* encodes a hash of the account's public key, a tag, and a checksum. This kind of address starts with the uppercase letter `X` if it is intended for use on the production XRP Ledger (mainnet). It starts with the uppercase letter `T` if it is intended for use on a test network such as Testnet or Devnet.
 
 ## Account Sequence Number
 
-Every XRP Ledger account has a *sequence number* that is used to keep transactions in order. Every transaction must have a sequence number. A transaction can only be executed if it has the next sequence number in order, of the account sending it. This prevents one transaction from executing twice and transactions executing out of order. The sequence number starts at `1` and increments for each transaction that the account makes.

+## computeBinaryTransactionHash
+
+`computeBinaryTransactionHash(txBlobHex: string): string`
+
+Returns the hash (id) of a binary transaction blob.
+
+This is a static method on the `RippleAPI` class.
+
+### Parameters
+
+This method takes one parameter, a string containing a binary transaction in hex.
+
+### Return Value
+
+This method returns a string representing the transaction's id (hash).
+
+### Example
+
+```javascript
+const signed_blob = '120000228000000024000B2E5A201B0066374B61400000003B9ACA0068400000000000000C732102356E89059A75438887F9FEE2056A2890DB82A68353BE9C0C0C8F89C0018B37FC74473045022100B3721EEB1ED6DFF29FB8B209E2DE6B54A0A6E44D52D926342F3D334BE98F08640220367A74107AD5DEAEFA3AB2984C161FC23F30B2704BB5CC984358BA262177A4568114F667B0CA50CC7709A220B0561B85E53A48461FA883142B71D8B09B4EE8DAA68FB936C23E3A974713BDAC'

+## classicAddressToXAddress
+
+`classicAddressToXAddress(classicAddress: string, tag: number | false[, test: boolean]): string`
+
+Convert a classic address and tag to an X-address.
+
+If `test` is `true`, the address with start with `T` and readers of the address will know that the address is intended for use on a test network.
+
+### Example: Encode an X-address with tag 4294967295
+
+```javascript
+const RippleAPI = require('ripple-lib').RippleAPI
+const xAddress = RippleAPI.classicAddressToXAddress('rGWrZyQqhTp9Xu7G5Pkayo7bXjH4k4QYpf', 4294967295)
+console.log(xAddress)
+```

+```
+
+## xAddressToClassicAddress
+
+`xAddressToClassicAddress(xAddress: string): {classicAddress: string, tag: number | false, test: boolean}`
+
+Convert an X-address to a classic address and tag.
+
+Since `0` is a valid tag, use `if (tag !== false)` to you want to check for a tag.
+
+If the address is intended for use on a test network, `test === true`. Otherwise, `test === false`.
+
+### Example
+
+```javascript
+const RippleAPI = require('ripple-lib').RippleAPI
+const address = RippleAPI.xAddressToClassicAddress('XVLhHMPHU98es4dbozjVtdWzVrDjtV18pX8yuPT7y4xaEHi')

 ## submit
 
-`submit(signedTransaction: string): Promise<object>`
+`request('submit', {tx_blob: string, fail_hard: boolean}): Promise<object>`
 
-Submits a signed transaction. The transaction is not guaranteed to succeed; it must be verified with [getTransaction](#gettransaction).
+The `submit` method applies a transaction and sends it to the network to be confirmed and included in future ledgers.
+
+This method takes a signed, serialized transaction as a binary blob, and submits it to the network as-is. Since signed transaction objects are immutable, no part of the transaction can be modified or automatically filled in after submission.
+
+To send a transaction as robustly as possible, you should construct and sign it in advance, persist it somewhere that you can access even after a power outage, then `submit` it as a `tx_blob`. After submission, monitor the network with the `tx` method to see if the transaction was successfully applied; if a restart or other problem occurs, you can safely re-submit the `tx_blob` transaction: it won't be applied twice since it has the same sequence number as the old transaction.
 
 ### Parameters
 
-<%- renderSchema('input/submit.json') %>
+| `Field`     | Type    | Description                                          |
+|:------------|:--------|:-----------------------------------------------------|
+| `tx_blob`   | String  | Hex representation of the signed transaction to submit. This can be a multi-signed transaction. |
+| `fail_hard` | Boolean | (Optional, defaults to false) If true, and the transaction fails locally, do not retry or relay the transaction to other servers |
 
 ### Return Value
 
-This method returns an object with the following structure:
+When successful, this method returns an object containing the following fields:

+| `Field`                 | Type    | Description                              |
+|:------------------------|:--------|:-----------------------------------------|
+| `engine_result`         | String  | Text [result code](https://xrpl.org/transaction-results.html) indicating the preliminary result of the transaction, for example `tesSUCCESS` |
+| `engine_result_code`    | Integer | Numeric version of the [result code](https://xrpl.org/transaction-results.html). **Not recommended.** |
+| `engine_result_message` | String  | Human-readable explanation of the transaction's preliminary result |
+| `tx_blob`               | String  | The complete transaction in hex string format |
+| `tx_json`               | Object  | The complete transaction in JSON format  |
+| `accepted`              | Boolean | The value `true` indicates that the transaction was applied, queued, broadcast, or kept for later. The value `false` indicates that none of those happened, so the transaction cannot possibly succeed as long as you do not submit it again and have not already submitted it another time. [New in: rippled 1.5.0] |
+| `account_sequence_available` | Number | The next [Sequence Number](https://xrpl.org/basic-data-types.html#account-sequence) available for the sending account after all pending and [queued](https://xrpl.org/transaction-queue.html) transactions. [New in: rippled 1.5.0] |
+| `account_sequence_next` | number  | The next [Sequence Number](https://xrpl.org/basic-data-types.html#account-sequence) for the sending account after all transactions that have been provisionally applied, but not transactions in the [queue](https://xrpl.org/transaction-queue.html). [New in: rippled 1.5.0] |
+| `applied`               | Boolean | The value `true` indicates that this transaction was applied to the open ledger. In this case, the transaction is likely, but not guaranteed, to be validated in the next ledger version. [New in: rippled 1.5.0] |
+| `broadcast`             | Boolean | The value `true` indicates this transaction was broadcast to peer servers in the peer-to-peer XRP Ledger network. (Note: if the server has no peers, such as in [stand-alone mode](https://xrpl.org/rippled-server-modes.html#reasons-to-run-a-rippled-server-in-stand-alone-mode), the server uses the value `true` for cases where it _would_ have broadcast the transaction.) The value `false` indicates the transaction was not broadcast to any other servers. [New in: rippled 1.5.0] |
+| `kept`                  | Boolean | The value `true` indicates that the transaction was kept to be retried later. [New in: rippled 1.5.0] |
+| `queued`                | Boolean | The value `true` indicates the transaction was put in the [Transaction Queue](https://xrpl.org/transaction-queue.html), which means it is likely to be included in a future ledger version. [New in: rippled 1.5.0] |
+| `open_ledger_cost`      | String  | The current [open ledger cost](https://xrpl.org/transaction-cost.html#open-ledger-cost) before processing this transaction. Transactions with a lower cost are likely to be [queued](https://xrpl.org/transaction-queue.html). [New in: rippled 1.5.0] |
+| `validated_ledger_index` | Integer  | The [ledger index](https://xrpl.org/basic-data-types.html#ledger-index) of the newest validated ledger at the time of submission. This provides a lower bound on the ledger versions that the transaction can appear in as a result of this request. (The transaction could only have been validated in this ledger version or earlier if it had already been submitted before.) |
+
+Note: Many situations can prevent a transaction from processing successfully, such as a lack of trust lines connecting the two accounts in a payment, or changes in the state of the ledger since the time the transaction was constructed. Even if nothing is wrong, it may take several seconds to close and validate the ledger version that includes the transaction. Do not consider the transaction's results final until they appear in a validated ledger version.

+/**
+ * When implementing Reliable Transaction Submission, there are many potential solutions, each with different trade-offs. The main decision points are:
+ * 1) Transaction preparation:
+ *    - How do we decide which account sequence and LastLedgerSequence numbers to use?
+ *      (To prevent unintentional duplicate transactions, an {account, account_sequence} pair can be used as a transaction's idempotency key)
+ *    - How do we decide how much to pay for the transaction fee? (If our transactions have been failing due to low fee, we should consider increasing this value)
+ * 2) Transaction status retrieval. Options include:
+ *    - Poll for transaction status:
+ *      - On a regular interval (e.g. every 3-5 seconds), or
+ *      - When a new validated ledger is detected
+ *      + (To accommodate an edge case in transaction retrieval, check the sending account's Sequence number to confirm that it has the expected value;
+ *         alternatively, wait until a few additional ledgers have been validated before deciding that a transaction has definitively not been included in a validated ledger)
+ *    - Listen for transaction status: scan all validated transactions to see if our transactions are among them
+ * 3) What do we do when a transaction fails? It is possible to implement retry logic, but caution is advised. Note that there are a few ways for a transaction to fail:
+ *    A) `tec`: The transaction was included in a ledger but only claimed the transaction fee
+ *    B) `tesSUCCESS` but unexpected result: The transaction was successful but did not have the expected result. This generally does not occur for XRP-to-XRP payments
+ *    C) The transaction was not, and never will be, included in a validated ledger [3C]
+ *
+ * References:
+ * - https://xrpl.org/reliable-transaction-submission.html

+ * - https://xrpl.org/get-started-with-rippleapi-for-javascript.html
+ * - https://xrpl.org/monitor-incoming-payments-with-websocket.html
+ *
+ * For the implementation in this example, we have made the following decisions:
+ * 1) The script will choose the account sequence and LastLedgerSequence numbers automatically. We allow ripple-lib to choose the fee.
+ *    Payments are defined upfront, and idempotency is not needed. If the script is run a second time, duplicate payments will result.
+ * 2) We will listen for notification that a new validated ledger has been found, and poll for transaction status at that time.
+ *    Futhermore, as a precaution, we will wait until the server is 3 ledgers past the transaction's LastLedgerSequence
+ *    (with the transaction nowhere to be seen) before deciding that it has definitively failed per [3C]
+ * 3) Transactions will not be automatically retried. Transactions are limited to XRP-to-XRP payments and cannot "succeed" in an unexpected way.

+# XRP Ledger Hashes
+
+Methods to hash XRP Ledger objects
+
+## Computing a transaction hash (ID)
+
+### computeBinaryTransactionHash = (txBlobHex: string): string
+
+Compute the hash of a binary transaction blob.
+
+### computeTransactionHash = (txJSON: any): string
+
+Compute the hash of a transaction in txJSON format.
+
+## [Hash Prefixes](https://xrpl.org/basic-data-types.html#hash-prefixes)
+
+In many cases, the XRP Ledger prefixes an object's binary data with a 4-byte code before calculating its hash, so that objects of different types have different hashes even if the binary data is the same. The existing 4-byte codes are structured as 3 alphabetic characters, encoded as ASCII, followed by a zero byte.
+
+Some types of hashes appear in API requests and responses. Others are only calculated as the first step of signing a certain type of data, or calculating a higher-level hash. Some of following methods internally use some of the 4-byte hash prefixes in order to calculate the appropriate hash.
+
+### computeBinaryTransactionSigningHash = (txBlobHex: string): string
+
+In order to single-sign a transaction, you must perform these steps:
+
+1. Assuming the transaction is in JSON format (txJSON), `encode` the transaction in the XRP Ledger's binary format.
+2. Hash the data with the appropriate prefix (`0x53545800` if single-signing, or `0x534D5400` if multi-signing).
+3. After signing, you must re-serialize the transaction with the `TxnSignature` field included.
+
+The `computeBinaryTransactionSigningHash` helps with step 2, automatically using the `0x53545800` prefix needed for single-signing a transaction.
+
+For details, see [Serialization Format](https://xrpl.org/serialization.html).
+
+_Removed:_ `computeTransactionSigningHash`, which took txJSON as a parameter. It was part of the deprecated ripple-hashes library. If you have txJSON, `encode` it with [ripple-binary-codec](https://github.com/ripple/ripple-binary-codec) first. Example: `return computeBinaryTransactionSigningHash(encode(txJSON))`
+
+### computeAccountLedgerObjectID = (address: string): string
+
+Compute the hash of an account, given the account's classic address (starting with `r`).
+
+### computeSignerListLedgerObjectID = (address: string): string
+
+Compute the hash of an account's SignerList.
+
+### computeOrderID = (address: string, sequence: number): string
+
+Compute the hash of an order, given the owner's classic address (starting with `r`) and the account sequence number of the `OfferCreate` order transaction.
+
+### computeTrustlineHash = (address1: string, address2: string, currency: string): string
+
+Compute the hash of a trustline, given the two parties' classic addresses (starting with `r`) and the currency code.
+
+### computeTransactionTreeHash = (transactions: any[]): string
+
+### computeStateTreeHash = (entries: any[]): string
+
+### computeLedgerHash = (ledgerHeader): string
+
+Compute the hash of a ledger.
+
+### computeEscrowHash = (address, sequence): string
+
+Compute the hash of an escrow, given the owner's classic address (starting with `r`) and the account sequence number of the `EscrowCreate` escrow transaction.
+
+### computePaymentChannelHash = (address, dstAddress, sequence): string
+
+Compute the hash of a payment channel, given the owner's classic address (starting with `r`), the classic address of the destination, and the account sequence number of the `PaymentChannelCreate` payment channel transaction.
