Where the money sits and how it leaves
The creator share of every curve trade, 0.30% today, accrues inside the FeeCollector per creator and per asset. Nothing is pushed. The creator wallet pulls, and only that wallet has a balance to pull.
claimCreatorFees()Pull accrued native-coin fees to the caller. Only the creator wallet has a balance.
claimCreatorFeesToken(address asset)Same for an ERC-20 quote asset such as a stock token.
Native-coin fees and ERC-20 fees are separate balances, so a creator with an ETH-paired token and a stock-paired token claims twice: claimCreatorFees() for the first, claimCreatorFeesToken(asset) for the second. Each claim emits CreatorFeeClaimed, and the running totals come from FeeCollected on the events page.
The current split and what the platform share pays for are on the fee structure page. Rates are read from GET /config, not fixed here.
