Methods for building transactions.

hash 🔒

Transaction identifiers for Zcash.

joinsplit 🔒

lock_time 🔒

Transaction LockTime.

memo 🔒

serialize 🔒

Contains impls of ZcashSerialize, ZcashDeserialize for all of the transaction types, so that all of the serialization logic is in one place.

Structs

AuthDigest

An authorizing data commitment hash as specified in ZIP-244.

Hash

A transaction ID, which uniquely identifies mined v5 transactions, and all v1-v4 transactions.

HashType

The different SigHash types, as defined in https://zips.z.cash/zip-0143

JoinSplitData

A bundle of JoinSplit descriptions and signature data.

Memo

A 512-byte (plaintext) memo associated with a note, as described in protocol specification §5.5.

SerializedTransaction

A serialized transaction.

SigHash

A Signature Hash (or SIGHASH) as specified in https://zips.z.cash/protocol/protocol.pdf#sighash

SigHasher

A SigHasher context which stores precomputed data that is reused between sighash computations for the same transaction.

UnminedTx

An unmined transaction, and its pre-calculated unique identifying ID.

VerifiedUnminedTx

A verified unmined transaction, and the corresponding transaction fee.

WtxId

A witnessed transaction ID, which uniquely identifies unmined v5 transactions.

Enums

LockTime

A Bitcoin-style locktime, representing either a block height or an epoch time.

Transaction

A Zcash transaction.

UnminedTxId

A unique identifier for an unmined transaction, regardless of version.

Constants
