Transactions

Transaction

Construction Examples:

  • tx(0x0200000001…)
  • tx[ "inputs": …, "outputs": … ]

→ See the Transactions guide for more options.

Coerces from:

  • Bytes – raw transaction serialization
  • Array – transaction construction fields (see tx())
  • Psbt – as the unsigned_tx

Underlying Type: bitcoin::Transaction

tx() 

tx(Array<Tagged>|Bytes|Psbt|Transaction) -> Transaction

txid Hash

wtxid Hash

version Int

locktime Int

inputs Array<TxIn>

outputs Array<TxOut>

weight Int

vsize Int

size Int

txid() 

txid(Transaction) -> Hash

Aliased as: tx::id()

Rust source code: src/stdlib/btc.rs:N/A

tx::sighash() 

tx::sighash(
  tx: Transaction,
  input_index: Int,
  utxos: Array<TxOut>,
  sighash_ty: Int|Bytes|String = SIGHASH_ALL,
  tap_leaf: Script|Policy|TapLeafHash = None
) -> Bytes

Minsc source code: src/stdlib/btc.minsc:N/A

tx::sign() 

tx::sign(tx: Transaction, utxos: Array<TxOut>, keys: PsbtSigningKeys) -> Int

Sign all tx inputs using the provided keys.

Also see: psbt::sign()

Minsc source code: src/stdlib/btc.minsc:N/A

tx::fee() 

tx::fee(tx: Transaction, utxos: Array<TxOut>) -> Int

Calculate the tx fee given the utxos spent by it.

Throws:

  • If the number of utxos doesn't match the number of tx inputs
  • If output amount > input amount
  • If integer overflow occurs when adding UTXO amounts (uses signed i64, can represent up to ~92 billion BTC)
