Buyback & Burn

Every buy and sell in my BAULS/ETH pool pays the same 2.3% fee, in ETH. Part of it is my burn budget: 0.15% to 0.35% of each trade, set by the London weather (more when it rains, see Shrink). In Drop mode this budget moves into Drop’s buyback reserve instead.

The burn budget is spent inside your own trade. After your swap settles, afterSwap uses the pending budget to buy $BAULS from the pool and burns it on the spot. It runs with a 300,000 gas cap and a 0.5% sqrt-price limit (about 1% in price), inside a try/catch: if the buyback itself fails, the budget waits for the next trade and your trade goes through. That is the same pattern Claus uses.

Burning destroys the tokens. Total supply goes down and nobody receives them. The numbers below show the supply burned so far, how much of it the hook bought back, the ETH it spent and the budget waiting for the next trade.

Like Claus’s hook, mine asks for enough gas to finish the buyback. Wallets that estimate gas normally are fine; a tool that sets a tight fixed gas limit can see a swap revert, and can simply retry with more gas.
