Class KeyChainTransactionSigner

java.lang.Object

org.bitcoinj.signers.StatelessTransactionSigner

org.bitcoinj.signers.CustomTransactionSigner

org.bitcoinj.testing.KeyChainTransactionSigner

All Implemented Interfaces:

TransactionSigner

public class KeyChainTransactionSigner
extends CustomTransactionSigner

Transaction signer which uses provided keychain to get signing keys from. It relies on previous signer to provide derivation path to be used to get signing key and, once gets the key, just signs given transaction immediately.

It should not be used in test scenarios involving serialization as it doesn't have proper serialize/deserialize implementation.
