Simulate Transaction

To simulate a transaction, you can use simulateTransaction method of the simulator namespace:

const callerAddress = '0xDBcB6Db1FFEaA10cd157F985a8543261250eFA46';
const counterContract = '0x93Cc0A80DE37EC4A4F97240B9807CDdfB4a19fB1';

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

  console.log('Simulated transaction:', transaction);
} catch (error) {
  console.error('Error. Failed to simulate transaction: ', error);
}
