addInput

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

• Parameters

  • hash: Uint8Array
  • index: number
  • Optionalsequence: number
  • OptionalscriptSig: Uint8Array

  Returns number

addOutput

• addOutput(scriptPubKey, value): number

• Parameters

  • scriptPubKey: Uint8Array
  • value: bigint

  Returns number

byteLength

• byteLength(_ALLOW_WITNESS?): number

• Parameters

  • _ALLOW_WITNESS: boolean = true

  Returns number

clone

• clone(): Transaction

• Returns Transaction

getHash

• getHash(forWitness?): Uint8Array

• Parameters

  • OptionalforWitness: boolean

  Returns Uint8Array

getId

• getId(): string

• Returns string

hasWitnesses

• hasWitnesses(): boolean

• Returns boolean

hashForSignature

• hashForSignature(inIndex, prevOutScript, hashType): Uint8Array

• 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: Uint8Array
  • hashType: number

  Returns Uint8Array

hashForWitnessV0

• hashForWitnessV0(inIndex, prevOutScript, value, hashType): Uint8Array

• Parameters

  • inIndex: number
  • prevOutScript: Uint8Array
  • value: bigint
  • hashType: number

  Returns Uint8Array

hashForWitnessV1

• hashForWitnessV1(inIndex, prevOutScripts, values, hashType, leafHash?, annex?): Uint8Array

• Parameters

  • inIndex: number
  • prevOutScripts: Uint8Array[]
  • values: bigint[]
  • hashType: number
  • OptionalleafHash: Uint8Array
  • Optionalannex: Uint8Array

  Returns Uint8Array

isCoinbase

• isCoinbase(): boolean

• Returns boolean

setInputScript

• setInputScript(index, scriptSig): void

• Parameters

  • index: number
  • scriptSig: Uint8Array

  Returns void

setWitness

• setWitness(index, witness): void

• Parameters

  • index: number
  • witness: Uint8Array[]

  Returns void

stripWitnesses

• stripWitnesses(): void

• Returns void

toBuffer

• toBuffer(buffer?, initialOffset?): Uint8Array

• Parameters

  • Optionalbuffer: Uint8Array
  • OptionalinitialOffset: number

  Returns Uint8Array

toHex

• toHex(): string

• Returns string

virtualSize

• virtualSize(): number

• Returns number

weight

• weight(): number

• Returns number

StaticfromBuffer
