Module fees 

Fee math for bonding-curve and AMM quotes (basis points as u64).

Structs

AmmFeeBps

AMM fees split into LP, protocol, and coin-creator components.

BondingCurveFeeBps

Bonding-curve fees split into protocol and creator components. The AMM-style LP fee is not part of the bonding-curve fee model.

Functions

bonding_curve_market_cap

Bonding-curve market cap in lamports. marketCap = virtualQuoteReserves * mintSupply / virtualTokenReserves.

ceil_div

ceil(a / b) for non-zero b.

compute_amm_fee_bps

AMM trade fee bps: tiered for pump pools, flat_fees for others, else globals.

compute_bonding_curve_fee_bps

Resolve the bps for a bonding-curve trade. When fee_config is None, fall back to the flat fees on Global. When provided, use the tiered fees indexed by current market cap.

creator_fee_amount

fee_amount(amount, basis_points), or 0 when creator is Pubkey::default() (the convention for “no creator fee on this trade”).

fee_amount

ceil(amount * basis_points / 10_000).

is_pump_pool

true iff pool_creator matches the canonical pump-program-derived pool authority for base_mint. Used to decide whether a pool gets tiered fees (pump pools) or flat fees (third-party pools).

pool_market_cap

AMM pool market cap in lamports. marketCap = quoteReserve * baseMintSupply / baseReserve.
