Struct UnsignedTransaction 

pub struct UnsignedTransaction { /* private fields */ }

An unsigned transaction with the chain hash baked in.

Created by [UnsignedTransaction::build]. Contains everything needed to produce signable bytes without a client reference.

Implementations

impl UnsignedTransaction

pub fn to_bytes(&self) -> SDKResult<Vec<u8>>

Serialize into the bytes that must be signed.

Borsh-serializes the transaction and appends the chain hash (32 bytes) as a domain separator.

pub fn builder<'f1>() -> UnsignedTransactionBuilder<'f1>

Build an unsigned transaction.

The returned UnsignedTransaction contains the chain hash, so to_bytes() produces signable bytes without needing a client reference.

Example

let unsigned = UnsignedTransaction::builder()
    .call_message(call_msg)
    .max_fee(10_000_000)
    .client(&client)
    .build()?;

let signable = unsigned.to_bytes()?;
let signature: [u8; 64] = external_signer.sign(&signable);
let pub_key: [u8; 32] = external_signer.public_key();
let signed = Transaction::from_parts(unsigned, signature, pub_key);
