MegaEngage

1) Connect & Add MegaETH Testnet

Chain ID 6342 · RPC https://carrot.megaeth.com/rpc · Explorer megaexplorer.xyz

Get test ETH (faucet):

• Official testnet portal
• Docs: Faucet

2) Fire a Test Transaction

Sends a tiny self-transfer on MegaETH Testnet (needs faucet ETH).

3) Interact with your Counter Contract

Deploy once in Remix (instructions below), paste the address here, then Read / increment().

How to deploy in Remix

1. Open Remix IDE and create MegaCounter.sol.
2. Paste the code below. Compile with Solidity 0.8.20+.
3. In Deploy & run transactions, select Injected Provider – MetaMask and switch MetaMask to MegaETH Testnet (chainId 6342).
4. Click Deploy, copy the contract address, paste it above, then try Read / increment().

pragma solidity ^0.8.20;

contract MegaCounter {
    uint256 public count;
    event Increment(address indexed by, uint256 newCount, string message);

    function increment(string calldata message) external {
        unchecked { count += 1; }
        emit Increment(msg.sender, count, message);
    }
}
