模拟交易 - Tenderly

Tenderly SDK 提供了 Simulator 类用于模拟交易。有关按步骤的演示，请参见模拟交易教程。要运行模拟，请在 tenderly 实例上调用 simulator 命名空间中的 simulateTransaction 方法：

example.js

const transaction = await tenderly.simulator.simulateTransaction({
  transaction: {
    from: callerAddress,
    to: counterContract,
    gas: 20000000,
    gas_price: '19419609232',
    value: 0,
    input: counterContractAbiInterface.encodeFunctionData('inc', []),
  },
  blockNumber: 3237677,
});

您也可以通过调用 simulateBundle 方法模拟一组交易：

example.js

const simulations = await tenderly.simulator.simulateBundle({
  transactions: [
    {
      from: fromWalletAddress,
      to: myTokenAddress,
      gas: 0,
      gas_price: '0',
      value: 0,
      input: myTokenAbiInterface.encodeFunctionData('approve', [toWalletAddress, 1234567890]),
    },
    {
      from: toWalletAddress,
      to: myTokenAddress,
      gas: 0,
      gas_price: '0',
      value: 0,
      input: myTokenAbiInterface.encodeFunctionData('transferFrom', [
        fromWalletAddress,
        toWalletAddress,
        1234567890,
      ]),
    },
  ],
  blockNumber: 3262454,
  overrides: {
    [myTokenAddress]: {
      state: {
        [`_balances[${fromWalletAddress}]`]: '1234567891',
      },
    },
  },
});
