Struct Signer

pub struct Signer { /* private fields */ }

A transaction signer for Soroban operations.

The Signer manages an Ed25519 key pair and provides methods to sign Stellar transactions. It handles the conversion between various key formats used in the Stellar ecosystem and implements the Stellar transaction signing protocol.

Implementations

pub fn public_key(&self) -> PublicKey

Returns the public key associated with this signer.

Returns

The Stellar public key

pub fn account_id(&self) -> AccountId

Returns the Stellar account ID associated with this signer.

Returns

The Stellar account ID

pub fn sign_transaction( &self, tx: &Transaction, network_id: &Hash, ) -> Result<DecoratedSignature, SorobanHelperError>

Signs a transaction with this signer’s private key.
