signPsbt

This method will traverse all inputs that match the current address to sign.

Parameters

• psbtHex - string: the hex string of psbt to sign
• options
  • autoFinalized - boolean: whether finalize psbt after signing, default is true
  • toSignInputs - array:
  • index - number: which input to sign
  • address - string: (at least specify either an address or a publicKey) Which corresponding private key to use for signing
  • publicKey - string: (at least specify either an address or a publicKey) Which corresponding private key to use for signing
  • sighashTypes - number[]: (optionals) sighashTypes
  • disableTweakSigner - boolean :(optionals) When signing and unlocking Taproot addresses, the tweakSigner is used by default for signature generation. Enabling this allows for signing with the original private key.

Returns

Promise<string>: the hex string of signed psbt

Example

try {
  let res = await signPsbt(
    "70736274ff01007d....",
    {
        autoFinalized:false,
        toSignInputs:[
          {
            index: 0,
            address: "tb1q8h8....mjxzny",
          },
          {
            index: 1,
            publicKey: "tb1q8h8....mjxzny",
            sighashTypes: [1]
          },
          {
            index: 2,
            publicKey: "02062...8779693f",

        ]
    }
