Claim your profile
Someone put a curve on your handle. Everything it has collected for you is sitting in the contract, untouched, waiting. Three steps and it is yours: your 5% of every past trade, key #1, and every future trade paid straight to your wallet.
Prove the X account is yours
It has to be the X account linked from your FOMO profile. That link is what ties a handle on this site to a person.

Pick the wallet that gets paid
Take your profile
How this works, without the hand-waving: X tells our server which account you control, the roster says which profile that account is linked to, and the server signs a message saying that profile may be claimed to the wallet you connected. The contract checks that signature and nothing else. That signer key is a centralised part of BigFomo, it can only ever assign a profile to a wallet, and it can never move the curve reserve or anyone's keys. more in the docs.
