You can link your social accounts to your .box name, so apps that show your profile can point people to your other accounts. You manage these on the Social card of the Identity tab.

You can add a handle for each of these:

On the Identity tab, choose Edit Profile. The Social card shows a field for each platform. Enter your handle or username for that platform, not a full web address. To remove one, clear its field with the X next to it. If an entry is not a valid handle, my.box flags it (for example, "Please enter a valid GitHub handle.").

Social links are saved with the rest of your profile when you choose Save Changes. This writes them on-chain in a single transaction you approve in your wallet, so you need a connected wallet and a small amount of ETH for the network fee. See Set your ENS profile for how saving works.
