Importing Custom Tokens into Metamask

If you have a custom ERC20 token that you want to import into Metamask, you will first need to create an ERC20 token contract. For example, if your token is called "MyToken", you will need to create a contract called "MyToken.sol".

Next, you will need to create a file called "config.json" in your project folder and add the following lines:

"tokenContract": "MyToken.sol",

You will also need to add the following lines to your METAMASK.CLI configuration file:

"tokenURI": "https://metamask.io/accounts/0x1234abcd1234abcd1234abcd1234abcd1234abcd1234abcd/tokens",

Once you have added these lines to your configuration file, you can import your custom token by running the following command:

metamask import MyToken

Please note that you will need to replace "MyToken" with the name of your custom token.
