Fees

Compulsory 1% take

Every book takes 100 bps on the curve and, after graduation, the hook takes the same bps on swap output (pool fee is 0). Credits sit in SamecaFeeEscrow. Only the credited wallet can call claim. Creator pulls the creator share. The protocol wallet pulls the 10%. A stranger gets nothing.

Of that 1%: creator 90% · platform 10%. Creators cannot opt out or rewrite it. The snapshot is taken at launch. Owner may change the protocol share for future books only. Existing books do not move.

Optional extra creator tax

At launch the creator may add 1%, 2%, or 3% on top of the 1%, or none. 100% of that extra tax is theirs. The cap is 300 bps. It cannot be raised later. It is copied onto the curve and the hook (creatorTaxBps) and shown as part of the trade cost (feeBps + creatorTaxBps).

This is a live take, not a stored slogan. A 3% tax plus the 1% base is a 4% cost on that book. Say that.

Payouts

Fees are not pushed. They sit in escrow until the credited wallet claims. Payout is in that book’s quote: USDG, USDT, or USDC, plus any token-side take after graduation. Creator payout defaults to the deployer. The deployer may setFeeRedirect per token, per chain. That moves future earnings only.

There is no platform launch fee unless owner turns it on. If they do, the form shows it and it is paid with the launch in native gas units (ETH, BNB, or Arc native USDC).

Protocol fees sit on each chain in phase 1. They are not auto-bridged to Arc. Phase 2 is a keeper path, not a promise in v1.
