Simulate a Transaction

Before sending a transaction, you can simulate it to preview the effects and validate that it will succeed. Transaction simulation shows all asset transfers involved in the transaction.
Transaction simulation uses the currently selected primary wallet. Make sure the user has a wallet connected before attempting to simulate a transaction.
React Native
import { dynamicClient } from '<path-to-your-dynamicClient>';
import { parseEther } from 'viem';

const simulateEvmTransaction = async (to: `0x${string}`, amountEth: string) => {
  const simulationResult = await dynamicClient.wallets.simulateEVMTransaction({
    transaction: {
      from: dynamicClient.wallets.primary.address,
      to,
      value: parseEther(amountEth),
      data: '0x',
    },
    type: 'SignTransaction',
  });

  console.log('Simulation result:', simulationResult);
  return simulationResult;
};
