Payout timing and the bank check
The bank account is part of going live because a finished gig has to have somewhere to land.
Creators add a bank account before they go live. The account name is resolved against the bank so the payout is not a guess. That check is why 'I'll add my bank after the first job' is not an option. The first job is already too late to discover the account is wrong.
Release queues a payout. It does not promise the same minute. Paystack moves the transfer, and a failed transfer can be retried with a new reference so the provider does not treat the retry as a duplicate of the failure.
The account number is not on the public profile. Brands do not need it. The platform does, and only after the creator has been hired and the work approved. Public cards show the work. They do not show the bank.
