# User Identity

## Connect Wallet

Sign-in on Atticc is by connecting your wallet via [MetaMask](https://metamask.io/) or [WalletConnect](https://walletconnect.com/). Currently Atticc only supports [Ethereum](https://ethereum.org/en/learn/) mainnet. We plan to integrate more blockchains in the future.

## Decentralized Social Graph

On Atticc, you own your identity. Atticc uses [CyberConnect](https://cyberconnect.me/) as the underlying decentralized social graph protocol. All your social relationships on Atticc also exist on any other apps built with CyberConnect and vice verse.

## Username

* Atticc recommends using [ENS](https://ens.domains/) as your username, so that your identity is decentralized and interoperable. All users on Atticc with '.eth' at the end of their username are using ENS. 
* Alternatively you can create a username of your choice. However '.' is not an allowed character, differentiating users who are using ENS from the rest.
* If neither is selected, your wallet address will be the default username.

## Profile Picture

* You can select an NFT as your profile picture, which will turn your icon into a hexagon.
* Alternative you can select a picture of your choice, and get a default round icon.
* If neither is selected, your default icon will show the last 4 digits of your wallet address.

## Social Links

Your Twitter link is verified using CyberConnect's [Social Verifier SDK](https://docs.cyberconnect.me/V1/cyberconnect-sdk/connect-with-social-verifier/). Verifying it on Atticc is the same as verifying it on your CyberConnect [profile](https://app.cyberconnect.me/plaza). If you change your Twitter handle you will need to re-verify it.
