pump-fee-sharing

The PumpFees program distributes creator trading fees on-chain using BPS-based shares. It requires a Fee Sharing Config linking a creator, mint, pool, and shareholders with basis point allocations totaling 10,000 BPS.

Set up BPS-based fee-sharing by creating a Fee Sharing Config that links your creator, mint, and pool, then define shareholders with basis point allocations totaling exactly 10,000 BPS.

PumpFees config updates enforce a maximum of 10 shareholders, reject duplicate addresses, and require total shares to equal exactly 10,000 BPS to successfully update the shareholder set.

Fee-sharing supports graduated tokens by performing cross-program fee consolidation across Pump and PumpAMM. Proper pool handling is required to distribute fees for these tokens correctly.

The maximum number of shareholders allowed in a Solana fee distribution config is 10, with input validation also enforcing a minimum shareholder count, no duplicate addresses, and a 10,000 BPS total.

A pool is required for fee distribution when handling graduated tokens. The PumpFees program performs cross-program fee consolidation across Pump and PumpAMM, which requires proper pool configuration.
