多重签名流程示例

TronWeb让开发人员可以使用tronWeb.trx.multiSign方法轻松地执行多重签名。

1. 创建交易

const originalTransaction = await tronWeb.transactionBuilder.sendTrx('41e0d5217904dcb2d5453c2359b86df9673046c4ce', 100000, '4164eb61f763d3374a998989f06929c1bad87175ba');

2. 执行多重签名

let signedTransaction = await tronWeb.trx.multiSign(originalTransaction, '47e5e1a590a44e7e6f4349a4e3ea6a4f9a791e3fccb115ffbddffdbf6d0588e6', 2);

signedTransaction = await tronWeb.trx.multiSign(signedTransaction, 'd5f244307d3ab6dc5739b83ec913b662a24f87e873190e9c1a2d9709f579540c', 2);

signedTransaction = await tronWeb.trx.multiSign(signedTransaction, '9944b7010db0d44a861bca112e40365a934727c5c17f8dfd3b9cc7b31e8aeaf1', 2);

签名结果:

      {

}

这个方法需要传递原始的交易、用来签名的私钥和permission ID。permission ID是更新账户权限时生成的。用户可以通过getAccount来查看账户权限和permission ID。

注意:如果使用active permission,交易ID将被重新计算,将和tronWeb.transactionBuilder.sendTrx或者其他方法执行后的原始交易不同。

3. 检查交易签名权重

tronweb.trx.getSignWeight方法可以查看当前有多少地址进行了签名以及权重。它可以在多重签名过程中或结束后进行调用。

const signWeight = await tronWeb.trx.getSignWeight(signedTransaction, 2);

结果:

4. 检查approve列表

tronWeb.trx.getApprovedList可以查看有多少个地址已经对交易进行了签名。

const approvedList = await tronWeb.trx.getApprovedList(signedTransaction);

结果:

{
  "result": {
    
  },
  "approved_list": [
    "4164eb61f763d3374a998989f06929c1bad87175ba",

5. 广播交易

当多重签名结束后,用户可以把签名的交易广播出去,并通过getTransactionById检查该交易。

const result = await = tronWeb.trx.broadcast(signedTransaction);

结果:

  "transaction": {
    "signature": [
