Ethereum: Troubleshooting Guide to Send ETH from Contract to Metamask Wallet
As a developer, it can be frustrating to have problems with Ethereum-based contracts. One of the most common problems is sending ether (ETH) from smart contract to Metamask wallet, Remix, Ethereum’s popular web-based development environment.
In this article, we permeate the troubleshooting process to promote the problem solving and to ensure smooth implementation of the contract.
Problem: Submit ETH from contract to Metamask wallet
The problem you face is probably due to the following reasons:
- Incorrect Contract Function Signature : The withdrawal function must make a specific set of arguments, but it is possible that the function signature is incorrect or missing.
2.
Step by step the troubleshooting manual
- Check the contract function signature in remix
* Open the remix and select the installed contract.
* Click « Edit » to view the source code for the contract.
* Make sure the « Undo » function is determined by the correct arguments (such as uint256") and the return type (title [] ETH SEND).
- Check the Metamask wallet configuration
* Make sure the metamask wallet is correctly configured to install Ethereum:
+ Move to Metamask Settings> Network
+ Select "Ethereum" as a network
+ Click "Advanced" and check that "SIGN Private Key" is enabled
* Check that the contract feature signature is the same in the remix.
- Check the contract permissions
* Make sure your Metamask wallet has the necessary permits to install and call contracts:
+ Go to Metamask Settings> Account Settings
+ Click "Manage Wallet" and make sure the account is included under "contracts".
4.
* Create a new remix contract project with your installed contract.
* Install a simple contract that will be subtracted (for example,Function () Public {…}).
* Send some ETH to the contract with the metamask and check that it is correctly received.
Example Code
Here's an example code detail in the remix to show you how to install a basic contract:
Jsx
Import * as ethers from "ethers";
CONST CONTRACTADDRESS = "0X ..."; // Replace the contract title
Const Contractabi = ...; // replace ABI's contract
Async Function Main () {
Const Contract = New Ethers.Contract (Contractaddress, Contractabi, {
Payable: True,
});
Wait for the contract.withdraw (100000000); // Send 0.1 ETH to the contract
console.log ("Ether sent:", contract.lasttransection.value);
}
main();
Conclusion
If none of the above steps solve the problem, please give you more details of the code and configuration, including the following:
- The exact error message you see
- Any relevant code detail or log
