FfiTransactionSerializer

class FfiTransactionSerializer(networkId: String) : TransactionSerializer

FFI-based serializer backed by the Rust ledger.

Serializes a signed Intent to SCALE codec using the ledger's types. Converts Kotlin models → JSON → Rust FFI → SCALE hex.

Constructors

constructor(networkId: String)

Properties

bindingCommitmentHex

val bindingCommitmentHex: String?

The binding commitment captured by the last getSigningMessageForInput call, or null if none yet. A multi-input signer reads this after the first input and feeds it back as bindingHex for the remaining inputs so all signatures cover one shared binding.

Functions

getSigningMessageForInput

fun getSigningMessageForInput(inputs: List<UtxoSpend>, outputs: List<UtxoOutput>, inputIndex: Int, ttl: Long, bindingHex: String? = null): String?

Public API: Get signing message for a specific input.

getTransactionHash

fun getTransactionHash(sealedTxHex: String): String?

Get the Midnight transaction hash from a sealed transaction.

sealProvenTransaction

open override fun sealProvenTransaction(provenTxHex: String): String?

JNI: Seals a proven transaction by transforming the binding commitment.

serialize

open override fun serialize(intent: Intent): String

Serialize a signed Intent to SCALE codec hex.

serializeWithDust

fun serializeWithDust(inputs: List<UtxoSpend>, outputs: List<UtxoOutput>, signatures: List<ByteArray>, dustState: DustLocalState, seed: ByteArray, dustUtxosJson: String, ttl: Long, currentTimeMs: Long): String

Serialize a signed transaction with Dust fee payment to SCALE codec hex.
