Socket trading fee

Socket trading fee (fee-router v1)

A socket hooklet. It takes a small fee on every buy and sell in one socket pool and sends the income to your team wallet or into a Socket fee splitter.

How it works

1. You set a buy fee and a sell fee, each at most 1%, and a recipient. They never change after deploy. 2. You add the hooklet to your socket pool with a grant. The fee actually taken on a trade is the lowest of your fee, the grant, and the pool cap fixed when the pool was created. 3. On every trade the socket books the fee as a claim for this hooklet. No ETH moves during the trade. 4. Anyone can call `collect` on the socket. The ETH arrives here, Socket's SwapFee is charged once on it, and the rest goes to your recipient.

Roles

- **Owner:** can pause (no fee taken, trading continues) and resume. Cannot change the fee or the recipient, and cannot take the income. - **Anyone:** can route income that has arrived (`onCredit`) and retry a refused payout (`flush`). - **The socket:** the only address that can send this hooklet ETH or tell it about swaps.

Risks in plain English

- Traders pay this on top of the pons fee. The swap page shows them the pons-direct price next to yours, so a high fee just sends them elsewhere. - If your wallet refuses ETH, the income waits here until a retry works. Nobody else can withdraw it. - If the hooklet misbehaves, the socket skips it after three failures in an hour and the guardian can switch it off. The pool keeps trading.

Fee lanes

| Lane | When | Default | |---|---|---| | SwapFee | on the fee income when it is collected | 0.50% of the income |

Nothing is charged on the trade itself by Socket. If the recipient is a Socket splitter, it does not charge again.

What if

- **I want a different fee?** Deploy a new fee router and propose it for your pool. Raising a fee waits the pool delay; lowering or removing applies at once. - **I lose my wallet?** The fee keeps flowing to the recipient you set. Only pausing needs the owner. - **Socket's guardian switches it off?** Trading continues with no fee from this hooklet. Only the Socket owner (48-hour timelock) can switch it back on.
