Sweep
Every swap in a ClikodT pool pays one fee on what goes into it. The pawl banks it as a claim against the pool manager, and this lever redeems the claim and hands it to the payee fixed in the contract.
Banked, in ETH
0 ETH
Nothing banked. A pool clicks off its fee when somebody swaps in it: buys pay in ETH, sells pay in the token.
Anyone can pull it
There is no recipient argument on the pawl and the payee is an immutable, so permission would change nothing. Whoever signs pays the gas; the money goes where it was always going. Fees from sells are banked in the token rather than ETH and are swept the same way, several currencies in one call.
