public final class SolanaTransaction

Object
SolanaTransaction

A Solana transaction: a SolanaMessage and one Ed25519 signature per required signer. A slot whose signer has not signed yet holds 64 zero bytes, which is how a transaction is passed between parties that sign it in turn.

Constructors

public SolanaTransaction(SolanaMessage message) An unsigned transaction for a message.

Methods

`public` `SolanaMessage getMessage()`	The message.
`public void sign(byte[] privateKey)`	Signs with the 32-byte Ed25519 seed of one of the message’s signers.
`public void addSignature(SolanaAddress signer, byte[] signature)`	Places a signature made elsewhere, for instance by a hardware wallet.
`public boolean isFullySigned()`	Whether every required signature is present and valid.
`public byte[] getSignature(int index)`	The signature of a signer slot, a copy; all zeros while unsigned.
`public` `String getId()`	The transaction id: the fee payer’s signature in Base58.
`public byte[] getMessageBytes()`	The bytes that are signed.
`public byte[] serialize()`	The wire form.
`public` `String toBase64()`	The Base64 wire form, what `sendTransaction` takes with `encoding: base64`.
`public static` `SolanaTransaction parse(byte[] data)`	Reads a transaction.
`public static` `SolanaTransaction fromBase64(String base64)`	Reads a Base64 transaction.

Constructor details

SolanaTransaction

public SolanaTransaction(SolanaMessage message)

An unsigned transaction for a message.

Method details

getMessage

public SolanaMessage getMessage()

The message.

sign

public void sign(byte[] privateKey)

Signs with the 32-byte Ed25519 seed of one of the message’s signers.

Throws

IllegalArgumentException: if the key is not one of the message’s signers

addSignature

public void addSignature(SolanaAddress signer, byte[] signature)

Places a signature made elsewhere, for instance by a hardware wallet.

Throws

IllegalArgumentException: if the signer is not required or the signature is invalid

isFullySigned

public boolean isFullySigned()

Whether every required signature is present and valid.

getSignature

public byte[] getSignature(int index)

The signature of a signer slot, a copy; all zeros while unsigned.

getId

public String getId()

The transaction id: the fee payer’s signature in Base58.

getMessageBytes

public byte[] getMessageBytes()

The bytes that are signed.

serialize

public byte[] serialize()

The wire form.

toBase64

public String toBase64()

The Base64 wire form, what sendTransaction takes with encoding: base64.

parse

public static SolanaTransaction parse(byte[] data)

Reads a transaction.

Throws

IllegalArgumentException: for malformed data, or a signature count that does not match the message

fromBase64

public static SolanaTransaction fromBase64(String base64)

Reads a Base64 transaction.
