# Customize Dapp Display in MetaMask > Configure your dapp's favicon icon and smart contract method names to improve how transactions and requests appear in the MetaMask UI. # Display in MetaMask Follow these best practices when displaying icons or method names in MetaMask. ## Display icons When your dapp makes a sign-in request to a MetaMask user, MetaMask may render a modal that displays your dapp icon. MetaMask retrieves this icon using the HTML selector ` link[rel="shortcut icon"]`, so you can follow the [favicon standard](https://en.wikipedia.org/wiki/Favicon) to customize your dapp icon. Add 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. ```html ``` ## Display method names MetaMask uses the [Ethereum Signature Database](https://www.4byte.directory/) 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](https://solidity.readthedocs.io/en/v0.4.21/abi-spec.html). 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](https://www.4byte.directory/submit/). ## Next steps - [Production readiness checklist](./production-readiness.md) - [Display tokens in MetaMask](../metamask-exclusive/display-tokens.md) - [Interact with smart contracts](../interact-with-contracts.md)
