It can be used standalone, but it is also exported as part of Kit [`@solana/kit`](https://github.com/anza-xyz/kit/tree/main/packages/kit). Transactions are created by compiling a transaction message. They must then be signed before being submitted to the network. ## Compiling a transaction ### Functions #### `compileTransaction()` Given a `TransactionMessage`, this function returns a `Transaction` object. This includes the compiled bytes of the transaction message, and a map of signatures. This map will have a key for each address that is required to sign the transaction. The transaction will not yet have signatures for any of these addresses. Whether a transaction message is ready to be compiled or not is enforced for you at the type level. In order to be signable, a transaction message must: - have a version and a list of zero or more instructions (ie. conform to `TransactionMessage`) - have a fee payer set (ie. conform to `TransactionMessageWithFeePayer`) - have a lifetime specified (ie. conform to `TransactionMessageWithBlockhashLifetime | TransactionMessageWithDurableNonceLifetime`) ## Signing transactions In order to be landed on the network, a transaction must be signed by all of the private keys belonging to accounts that are required signers of the transaction. ### Types #### `FullySignedTransaction` This type represents a transaction that is signed by all of its required signers. #### `TransactionWithSizeLimit` This type represents a transaction that is under or equal to the maximum size limit for transactions on the Solana network. #### `SendableTransaction` This type represents a transaction that has all the required conditions to be sent to the network. Namely: - It must be fully signed (ie. conform to `FullySignedTransaction`) - It must be within size limit (ie. conform to `TransactionWithSizeLimit`) The `SendableTransaction` type is a prerequisite of functions designed to land transactions on the network. ### Functions #### `getSignatureFromTransaction()` Given a transaction signed by its fee payer, this method will return the `Signature` that uniquely identifies it. This string can be used to look up transactions at a later date, for example on a Solana block explorer. ```ts import { getSignatureFromTransaction } from '@solana/transactions'; const signature = getSignatureFromTransaction(tx); console.debug(`Inspect this transaction at https://explorer.solana.com/tx/${signature}`); ``` ### `signTransaction()` Given an array of `CryptoKey` objects which are private keys pertaining to addresses that are required to sign a transaction, this method will return a new signed transaction of type `FullySignedTransaction`. This function will throw unless the resulting transaction is fully signed. ```ts import { generateKeyPair } from '@solana/keys'; import { signTransaction } from '@solana/transactions'; const signedTransaction = await signTransaction([myPrivateKey], tx); ``` ### `partiallySignTransaction()` This function is the same as `signTransaction()` but does not require the transaction to be signed by all signers. A partially signed transaction cannot be landed on the network, but can be serialized and deserialized. ## Serializing transactions Before sending a transaction to be landed on the network, you must serialize it in a particular way. You can use these types and functions to serialize a signed transaction into a binary format suitable for transit over the wire. ### Types #### `Base64EncodedWireTransaction` This type represents the wire format of a transaction as a base64-encoded string. ### Functions #### `getBase64EncodedWireTransaction()` Given a signed transaction, this method returns the transaction as a string that conforms to the `Base64EncodedWireTransaction` type. ```ts import { getBase64EncodedWireTransaction, signTransaction } from '@solana/transactions'; const serializedTransaction = getBase64EncodedWireTransaction(signedTransaction); const signature = await rpc.sendTransaction(serializedTransaction, { encoding: 'base64' }).send(); ``` --- _Source: https://npm.io/package/@solana/transactions · Machine-readable twin of the npm.io package page.
