Oncepay is an on-chain payment layer built around creator fees. Oncepay reads fee configurations directly from Solana and shows which tokens have already spent their allocation and which have not. Point a token's creator fees to a registered X handle. Sign in with X, sign a message with your wallet, and your handle becomes linked to your address. Assigning fees to @you resolves directly to that address. Every figure shown by Oncepay is tied to the Solana slot where it was read. If something is not built, Oncepay does not pretend otherwise. Oncepay takes no cut from creator fees. The launch transaction does not include a field that redirects creator fees to Oncepay. Read the data. Route the fees. Get paid.
