X (formerly Twitter)

Since SNS is a primitive of Solana that allows the mapping of names to a Solana account. This permits many things including associating your X handle to your Solana address.

Both X handles and .sol domain names are a part of SNS, yet are slightly different. An X handle can only be claimed by the owner of the X account. In order to guarantee this, the user needs to tweet the wallet address they want to associate with the account and then sign a transaction using the same wallet address.
