Connect wallet

1. Example code

import * as TC_CONNECT from "tc-connect";

const CONNECT_URL = 'https://wadary.regtest.trustless.computer/relayer';
const WALLET_URL = 'https://newbitcoinwallet.io';

const connector = new TC_CONNECT.DappConnect(CONNECT_URL, WALLET_URL);

try {
  const account = await connector.requestAccount({
    target: "_blank",
    redirectURL: "",
    signMessage: "",
  });
  console.log("account", account);
} catch (e) {
  // todo handle error
  // Reject | Create transaction error
}

2. Request

  • target: window.open type "_blank" | "_parent" | "_self" | "_top"
  • redirectURL: optional The url you want to redirect to when the request is successful.
  • signMessage: optional Message for sign.

3. Response

  • tcAddress: TC wallet address in use.
  • btcAddress: BTC wallet address in use.
  • accounts: Wallet's list of available accounts.
    • name: The account name.
    • tcAddress: TC wallet address.

Contract Integration

1. Define ABI

const ABI = [
  {
    "inputs": [
      {
        "internalType": "contract WrappedToken",
        "name": "token",
        "type": "address"
      },
      {
        "internalType": "uint256",
        "name": "amount",
        "type": "uint256"
      },
      {
        "internalType": "string",
        "name": "externalAddr",
        "type": "string"
      }
    ],
    "name": "burn",
    "outputs": [],
    "stateMutability": "nonpayable",
    "type": "function"
  },
];

2: Create calldata

import { ethers } from "ethers";

const ContractInterface = new ethers.utils.Interface(ABI);
const encodeAbi = ContractInterface.encodeFunctionData("burn", [
    tokenAddress,
    burnAmount,
    receiver
]);

3. Request sign transaction

import * as TC_CONNECT from "tc-connect";

const CONNECT_URL = 'https://wadary.regtest.trustless.computer/relayer';
const WALLET_URL = 'https://trustlesswallet.io';

const connector = new TC_CONNECT.DappConnect(CONNECT_URL, WALLET_URL);

const toAddress = "0xFC9a05654a5bBaBBc7c230eB718b363C23d833D2";

const response = await connector.requestSign({
    target: "_blank",
    calldata: encodeAbi,
    to: toAddress,
    value: "",
    redirectURL: "https://dapp_url.com",
    isInscribe: true,
    gasPrice: undefined,
    gasLimit: undefined,
    functionType: 'Burn',
    functionName: 'burn(address,uint256,string)',
});

console.log('Sign transaction response: ', response);

4. Request Payload

  • target: window.open type "_blank" | "_parent" | "_self" | "_top"

  • calldata: calldata for sign and send transaction.

  • to: destination address.

  • isExecuteTransaction: optionalTest execute transaction before broadcast, default true.

  • value: optional value TC sending transaction. // 1e18 = 1 TC

  • isInscribe: a flag to check whether to inscribe Bitcoin transaction:

    • isInscribe = true: Sign TC and Inscribe Bitcoin transaction.
    • isInscribe = false: Sign TC and do not Inscribe Bitcoin transaction.

  • gasPrice: optional auto estimated.

  • gasLimit: optional auto estimated.

  • redirectURL: optional The url you want to redirect to when the request is successful.

5. Response Payload

  • tcHash: TC transaction hash.

  • btcHash: optionalBTC transaction hash.

  • to: optionaldestination address.

  • from: sender address.
