Creator fees
Where the reserve's SPYx comes from.
Pump.fun charges a fee on every trade and passes part of it to the coin's creator. For a Flisk coin, that part is the reserve's only income.
Rate
For coins quoted in something other than SOL or USDC, the creator picks the rate at launch through creator_fee_bps, within the maximum set in Pump.fun's global config. The rate is shown on every coin's Flisk page.
Example
At a 1% creator fee, a coin that trades the equivalent of $1M in a day adds about $10K of SPYx to its reserve that day.
Collection
Fees wait in Pump.fun's vaults until someone calls collect_creator_fee_v2 on the curve or collect_coin_creator_fee on PumpSwap. Both are open to any caller and both pay the creator, which is the reserve. Flisk puts the call in front of every redeem.
is_holder_reward flag. With it, fees would go to holders directly and the reserve would get nothing.
