Get Signatures

Similar to signing messages, Panda Wallet can also getSignatures for a raw transaction.

It may look something like:

const wallet = initProvider(); // see "Detecting the Provider"

try {
    const sigRequests: SignatureRequest[] = [
  { 
    prevTxid: // txid string,
    outputIndex: 0,
    inputIndex: 0,
    satoshis: 1,
    address: // ordAddress string,
  },
  { 
    prevTxid: // txid string,
    outputIndex: 0,
    inputIndex: 1,
    satoshis: 1000,
    address: // bsvAddress string,
    script: // script as hex string
  }
];

const sigResponses: SignatureResponse[] = await wallet.getSignatures({
  rawtx: // unsignedTxRawHex string,
  sigRequests
});

// See types below for response

} catch (err) {
    console.log(err);
}

Types:

/** 
 * `SignatureRequest` contains required informations for a signer to sign a certain input of a transaction.
 */
export interface SignatureRequest {
  prevTxid: string;
  outputIndex: number;
  /** The index of input to sign. */
  inputIndex: number;
  /** The previous output satoshis value of the input to spend. */
  satoshis: number;
  /** The address(es) of corresponding private key(s) required to sign the input. */
  address: string | string[];
  /** The previous output script of input, default value is a P2PKH locking script for the `address` if omitted. */
  script?: string;
  /** The sighash type, default value is `SIGHASH_ALL | SIGHASH_FORKID` if omitted. */
  sigHashType?: number;
  /** 
   * Index of the OP_CODESEPARATOR to split the previous output script at during verification.
   * If undefined, the whole script is used.
   * */
  csIdx?: number;
  /** The extra information for signing. */
  data?: unknown;
}

/** 
 * `SignatureResponse` contains the signing result corresponding to a `SignatureRequest`.
 */
export interface SignatureResponse {
  /** The index of input. */
  inputIndex: number;
  /** The signature.*/
  sig: string;
  /** The public key bound with the `sig`. */
  pubKey: string;
  /** The sighash type, default value is `SIGHASH_ALL | SIGHASH_FORKID` if omitted. */
  sigHashType: number;
  /** The index of the OP_CODESEPARATOR to split the previous output script at.*/
  csIdx?: number;
