Metamask: Learning to write a basic contract that sends goerli ethereum to another contract

I’d be happy to help you with writing an article on Metamask for smart contracts.

Learning to Write a Basic Contract that Sends GOerli Ethereum to Another Contract

As a beginner in Solidity, learning to write a basic contract that sends GOerli Ethereum to another contract can seem like a daunting task. However, with the right guidance and resources, you can master this concept and start building your own decentralized applications (dApps).

What is Metamask?

Metamask is a popular tool for creating and managing multi-chain wallets, allowing users to store and transfer assets across different blockchain networks, including Ethereum, Binance Smart Chain, and others. In this article, we’ll focus on how to use Metamask to send GOerli Ethereum to another contract.

Setting Up Metamask

To start, you need to set up a Metamask wallet. Here’s how:

• Download the official Metamask wallet from the MetaMask website.

• Launch the Metamask app and connect your computer or mobile device.

• Fund your Metamask account with GOerli Ethereum (GOELF) by sending it to your new wallet.

Creating a Basic Contract

Now that you have a Metamask wallet, let’s create a basic contract in Solidity that sends GOerli Ethereum to another contract. We’ll use the contract function to deploy our contract and send the funds.

First, create a new file called Contract.sol with the following code:

pragma solidity ^0.8.0;


import "


contract MyContract {

    using SafeERC20 for (address, ERC20);


    // Define the contract variables

    address public owner;

    uint public balance;


    function _init(address owner) internal {

        owner = owner;

        balance = 0;

    }


    function sendGOELF() external pure returns (bool) {

        // Send GOerli Ethereum to another contract using Metamask

        address recipientAddress = "0x..."; // Replace with the recipient contract address

        bytes memory recipientAddressBytes = abi.encodePacked(recipientAddress);

        SafeERC20.safeTransferFrom(msg.sender, address(this), recipientAddressBytes);


        balance -= 1; // Subtract 1 from the owner's balance


        return true;

    }

}

Deploying the Contract

To deploy our contract using Metamask, follow these steps:

• Open the Metamask app and connect to your computer or mobile device.

• Fund your account with GOerli Ethereum (GOELF).

• Navigate to the “Deploy” section in the Metamask app.

• Select “Contract” as the deployment type.

• Choose the Contract.sol file we created earlier.

• Fill in the contract variables (owner and balance) and click “Deploy”.

• The contract will be deployed, and you’ll receive a link to view it on the blockchain.

Testing the Contract

To test our contract, navigate to the Metamask app and select “Contract” again.

• Fund your account with GOerli Ethereum (GOELF).

• Select the contract that we deployed earlier.

• Click “Deploy” again.

• The contract will be deployed, and you’ll receive a link to view it on the blockchain.

Sending GOerli Ethereum to Another Contract

Now that our contract is deployed, you can send GOerli Ethereum to another contract using Metamask:

• Open the Metamask app and connect to your computer or mobile device.

• Fund your account with GOerli Ethereum (GOELF).

• Navigate to the “Deploy” section in the Metamask app.

• Select the contract that we deployed earlier.

• Click on the “Send” button next to the contract address.

• Enter the recipient contract address and click “Send”.

Congratulations! You’ve successfully sent GOerli Ethereum to another contract using Metamask.
