Verify your X profile
Ownership follows the account, even after a rename.
An X username is a readable label. The permanent X account ID anchors fee ownership. Signing into another account or changing wallets does not transfer the entitlement.
Linking a payout wallet
After X verification, request a binding message and sign it with the chosen wallet. The server checks its identity, destination, expiry, nonce and signature before recording the link.
Verification sessions expire. Return through X authorization when the session ends. Keep access to both the recipient account and the wallet chosen for payout.
