Struct Transaction 

pub struct Transaction;

Transaction construction and serialization.

Use Transaction::builder() for signed transactions, or UnsignedTransaction::builder() for external signing.

Implementations

impl Transaction

pub fn from_parts( tx: UnsignedTransaction, signature: [u8; 64], pub_key: [u8; 32], ) -> SignedTransaction

Assemble a signed transaction from an unsigned transaction, a 64-byte Ed25519 signature, and a 32-byte public key.

Use after signing the bytes from UnsignedTransaction::to_bytes.

pub fn to_bytes(signed: &SignedTransaction) -> SDKResult<Vec<u8>>

Borsh-serialize a signed transaction to bytes.

Useful for byte-level comparison of two signed transactions.

pub fn to_base64(signed: &SignedTransaction) -> SDKResult<String>

Borsh-serialize and base64-encode a signed transaction.

pub fn builder<'f1, 'f2>() -> TransactionBuilder<'f1, 'f2>

Build a signed transaction.

Internally builds an unsigned transaction, serializes it, signs with the provided keypair, and assembles the result.

Example

let signed = Transaction::builder()
    .call_message(call_msg)
    .max_fee(10_000_000)
    .signer(&keypair)
    .client(&client)
    .build()?;

client.send_transaction(&signed).await?;
