Identification problem of the MetamSk chain in hardhat
Recently I found a problem by configuring my metamask wallet in Hardhat, an environment of popular Ethereum development. Specifically, I was trying to use Chainid: 1337 instead of ‘31337’ planned.
The problem:
My Hardhat.config.js file had already included the following configuration:
`JavaScript
module.exports = {
Solidity: "0.8.17",
Networks: {
Localhot: {
Host: 'localhost',
Port: 8545,
Chainid: 1337
}
},
// ... Other settings ...
};
The solution:
As a result, the problem is due to a difficult coding of the value 'Chainid in the hardhat configuration. Specifically, I had included 31337 instead of ‘1337.
To solve this problem, I simply changed my hardhat.config.js file to its original content:
JavaScript
module.exports = {
Solidity: "0.8.17",
Networks: {
Localhot: {
Host: 'localhost',
Port: 8545,
Chainid: 1337
}
},
// ... Other settings ...
};
What went wrong?
In my attempt to use31337as' Chainid, I inadvertently used a coded value instead of using the imported configuration of Metamask. This led to an error when Hardhat tried to solve the Chainid value.
Prevention and Solutions:
To avoid similar problems in the future, it is essential:
- Care your hardhat.config.js file and make sure all configurations are precise.
- Verify that you are using the chain ID value planned for MetamSk.
- Use a library or configuration tool that can handle the ‘chainid` value of MetamSk.
When taking these precautions, you should be able to configure your hardhat environment with the correct value of ‘Chainid’ and avoid similar problems in the future.
