addInput

• addInput(hash, index, sequence?, scriptSig?): number

• Parameters

  • hash: Buffer

  • index: number

  • Optional sequence: number

  • Optional scriptSig: Buffer

  Returns number

addOutput

• addOutput(scriptPubKey, value): number

• Parameters

  • scriptPubKey: Buffer

  • value: number

  Returns number

byteLength

• byteLength(_ALLOW_WITNESS?): number

• Parameters

  • _ALLOW_WITNESS: boolean = true

  Returns number

clone

• clone(): Transaction

• Returns Transaction

getHash

• getHash(forWitness?): Buffer

• Parameters

  • Optional forWitness: boolean

  Returns Buffer

getId

• getId(): string

• Returns string

hasWitnesses

• hasWitnesses(): boolean

• Returns boolean

hashForSignature

• hashForSignature(inIndex, prevOutScript, hashType): Buffer

• Hash transaction for signing a specific input.

  Bitcoin uses a different hash for each signed transaction input. This method copies the transaction, makes the necessary changes based on the hashType, and then hashes the result. This hash can then be used to sign the provided transaction input.

  Parameters

  • inIndex: number

  • prevOutScript: Buffer

  • hashType: number

  Returns Buffer

hashForWitnessV0

• hashForWitnessV0(inIndex, prevOutScript, value, hashType): Buffer

• Parameters

  • inIndex: number

  • prevOutScript: Buffer

  • value: number

  • hashType: number

  Returns Buffer

hashForWitnessV1

• hashForWitnessV1(inIndex, prevOutScripts, values, hashType, leafHash?, annex?): Buffer

• Parameters

  • inIndex: number

  • prevOutScripts: Buffer[]

  • values: number[]

  • hashType: number

  • Optional leafHash: Buffer

  • Optional annex: Buffer

  Returns Buffer

isCoinbase

• isCoinbase(): boolean

• Returns boolean

setInputScript

• setInputScript(index, scriptSig): void

• Parameters

  • index: number

  • scriptSig: Buffer

  Returns void

setWitness

• setWitness(index, witness): void

• Parameters

  • index: number

  • witness: Buffer[]

  Returns void

toBuffer

• toBuffer(buffer?, initialOffset?): Buffer

• Parameters

  • Optional buffer: Buffer

  • Optional initialOffset: number

  Returns Buffer

toHex

• toHex(): string

• Returns string

virtualSize

• virtualSize(): number

• Returns number

weight

• weight(): number

• Returns number

Static fromBuffer

• fromBuffer(buffer, _NO_STRICT?): Transaction

• Parameters

  • buffer: Buffer

  • Optional _NO_STRICT: boolean

  Returns Transaction

Static fromHex

• fromHex(hex): Transaction

• Parameters
