your x account, your wallet.
every coin that names your account sends all of its creator fees to a solana wallet keyed to your x id, made before you ever showed up. sign in with x and it is yours.
your @ may already have a wallet here.
if someone launched a coin naming your x account, its creator fees have been landing in a solana wallet made for your x id. sign in with x and privy opens that same wallet for you. nothing to link, nothing to prove: signing in is the claim.
