The water only gets deeper.

StonkFun pays every coin's creator a share of the trading fee on every buy and sell. On Narwhal, each coin's creator is its own engine wallet, so that fee lands with the engine instead of a person.

Once a coin graduates to its Raydium pool, the engine collects the waiting fees every few minutes, uses about half to buy the coin from its own pool, then adds the coins and the other half of the SOL to the pool as liquidity. The LP receipt it gets back is burned in the same transaction.

There's no pool to add to yet, so the fees wait with the engine (the tank you see on every coin). When the coin graduates at about 85 SOL, the engine pours the whole tank in.

No. The launcher is never the creator, so creator fees never reach them. The LP receipts are burned, so nobody can withdraw that liquidity. Not the launcher, not Narwhal.

Each engine's key is made when the coin is created and sealed to the engine worker's key. The website can create and seal keys but can't open them, and the worker only ever signs that engine's own collect, buy and add-liquidity transactions. Every one of them is public in the engine log.

StonkFun's own coin creation (about 0.02 SOL of account rent, no platform fee), a 0.01 SOL spark that pays the engine's network fees, and whatever first buy you choose. Narwhal takes nothing.

The more SOL a pool holds, the less any single sell moves the price. Fees from trading slowly turn into permanent depth, so the coin gets steadier the more it's traded.
