Ethereum: Having trouble sending ETH from contract to MetaMask wallet using Remix

Ethereum: A Troubleshooting Guide for Sending ETH from Contract to MetaMask Wallet

As a developer, it can be frustrating to run into issues with your Ethereum-based contracts. A common issue that arises is sending Ether (ETH) from a smart contract to a MetaMask wallet using Remix, the popular web development environment for Ethereum.

In this article, we will go through the troubleshooting process to help you resolve the issue and ensure your contract runs successfully.

Issue: Sending ETH from Contract to MetaMask Wallet

The issue you are facing is likely due to the following reasons:

• Incorrect contract function signature

  : The withdraw function should take a specific set of arguments, but it is possible that the function signature is incorrect or missing.

• Incorrect MetaMask Wallet Configuration: Make sure your MetaMask wallet is properly configured for Ethereum deployment and transaction signing.

Step-by-step troubleshooting guide

• Check contract function signature in Remix

• Open Remix and select your deployed contract.

• Click the “Edit” button to view the contract source code.

• Check if the withdraw function is defined with the correct arguments (e.g. uint256 amount) and return type (address[] eth send).

• Check MetaMask Wallet Configuration

• Make sure your MetaMask wallet is properly configured for Ethereum deployment:

+ Go to MetaMask Settings > Network

+ Select “Ethereum” as your network

+ Click “Advanced” and make sure “Sign with Private Key” is enabled

• Make sure the contract function signature matches the one in Remix.

• Check Contract Permissions

• Make sure your MetaMask wallet has the necessary permissions to deploy and call contracts:

+ Go to MetaMask Settings > Account Settings

+ Click “Manage Wallet” and make sure the account is listed under “Contracts”

• Test the withdraw function in Remix

• Create a new Remix contract project with your deployed contract.

• Deploy a simple contract that calls the “withdraw” function (e.g., “public withdraw() function { … } ).

• Send ETH to the contract using MetaMask and verify that it was received successfully.

Sample Code

Here’s an example snippet in Remix to demonstrate how to deploy a basic contract:

import * as ethers from "ethers";
const contractAddress = "0x..."; // Replace with your contract address
const contractAbi = ...; // Replace with your contract ABI
async function main() {
const contract = new ethers.Contract(contractAddress, contractAbi, {
payable: true,
});
await contract.withdraw(100000000); // Send 0.1 ETH to the contract
console.log("Ether sent:", contract.lastTransactionOutgoing.value);
}
mince();
