Write Smart Contract

Create a Solidity contract to store and retrieve data, then set up a deployment script to automate deployment on SupraEVM using Foundry.

Create a Smart Contract File

Set up the SimpleStorage.sol file in the src directory to define a basic Solidity smart contract that allows storing and retrieving a uint256 value on SupraEVM.


// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
contract SimpleStorage {
    uint256 public storedData;
 
    function set(uint256 x) public {
        storedData = x;
    }
 
    function get() public view returns (uint256) {
        return storedData;
    }
}

Create a Deployment Script

Write a deployment script in the script directory (DeploySimpleStorage.sol) to automate smart contract deployment on SupraEVM using Foundry’s scripting tools.


// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
import "forge-std/Script.sol";
import "../src/SimpleStorage.sol";
 
contract DeploySimpleStorage is Script {
    function run() external {
        uint256 privateKey = vm.envUint("PRIVATE_KEY");
        vm.startBroadcast(privateKey);
        new SimpleStorage();
        vm.stopBroadcast();
    }
}
