Contract.sol

and copy the contract below:

// SPDX-License-Identifier: MIT
pragma solidity 0.8.28;

contract SimpleStorage {

    uint256 public storedData; //Do not set 0 manually it wastes gas!

    event setEvent();
    
    function set(uint256 x) public {
        storedData = x;
        emit setEvent();
    }

}

Deploy and Verify​

warning

Note: Blockscout verification might fail during deployment. If this happens, verify the contract after it is deployed.

forge create src/Contract.sol:SimpleStorage \
--private-key $devTestnetPrivateKey \
--rpc-url https://rpc.dev.gblend.xyz/ \
--broadcast \
--verify \
--verifier blockscout \
--verifier-url https://blockscout.dev.gblend.xyz/api/

Verify Contract Already Deployed​

info

Replace variable

<contract_address>

with the deployed contract address on Fluent testnet.

forge verify-contract \
--rpc-url https://rpc.dev.gblend.xyz/ \
<contract_address> \
src/Contract.sol:SimpleStorage \
--verifier blockscout \
--verifier-url https://blockscout.dev.gblend.xyz/api/
