Display in MetaMask

Display icons​

When your dapp makes a login request to a MetaMask user, MetaMask may render a modal that displays your dapp icon.

MetaMask retrieves this icon using the HTML selector <head> link[rel="shortcut icon"], so you can follow the favicon standard to customize your dapp icon. Make sure to have a link tag within your dapp's head with rel = "shortcut icon", as in the following example. The tag's href attribute is used for assigning the dapp icon.

<head>
  <link rel="shortcut icon" href="https://your-dapp.com/your-icon.png" />
</head>

Display method names​

MetaMask uses the Ethereum Signature Database to display method names on the confirmation screen. For many common method names, such as token methods, this allows MetaMask to look up the method names by their method signature. However, sometimes you're using a method that isn't in that database, and MetaMask simply displays Contract Interaction to the user.

To register your contract's method names so they show in the MetaMask interface, submit each method's signature to the Ethereum Signature Database.
