Field Detail

partialTx

public final Transaction partialTx

keyPaths

public final java.util.Map<Script,java.util.List<ChildNumber>> keyPaths

HD key paths used for each input to derive a signing key. It's useful for multisig inputs only. The keys used to create a single P2SH address have the same derivation path, so to use a correct key each signer has to know a derivation path of signing keys used by previous signers. For each input signers will use the same derivation path and we need to store only one key path per input. As TransactionInput is mutable, inputs are identified by their scriptPubKeys (keys in this map).
