Integrating Simulation with 1 line of code

Learn how to effortlessly integrate Alchemy's Simulation APIs in your code base using just one line of code.

Implementing Simulation APIs is as easy as adding 1 line to your code base.

If you are already signing transactions via eth_signTransaction or any calling any other method that takes an unsigned transaction object, all you need to do is pass the object to alchemy_simulateAssetChanges.

eth_signTransaction

eth_signTransaction
1{
2  "jsonrpc": "2.0",
3  "method": "eth_signTransaction",
4  "id": 1,
5  "params": [
6    {
7      "from": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
8      "to": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
9      "value": "0x0",
10      "data": "0xa9059cbb000000000000000000000000fc43f5f9dd45258b3aff31bdbe6561d97e8b71de00000000000000000000000000000000000000000000000000000000000f4240"
11    }
12  ]
13}

Replace eth_signTransaction with alchemy_simulateAssetChanges to get simulation results.

alchemy_simulateAssetChanges
1{
2  "jsonrpc": "2.0",
3  "method": "alchemy_simulateAssetChanges",
4  "id": 1,
5  "params": [
6    {
7      "from": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
8      "to": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
9      "value": "0x0",
10      "data": "0xa9059cbb000000000000000000000000fc43f5f9dd45258b3aff31bdbe6561d97e8b71de00000000000000000000000000000000000000000000000000000000000f4240"
11    }

13}

That’s it!
