Take profits

Tick-walk fill-on-cross take profit on upward price crosses.

First-party rewrite inspired by LearnWeb3 take-profits hook. Mirror of StopLoss: registerProfit at a tick, afterSwap fills on upward crosses with unlock-wrapped swaps. 14 permission fields, OpenZeppelin BaseHook, current v4 API. No ERC1155 layer in this teaching cut. Listing is not an audit. Forge tests under test/TakeProfit.t.sol.

Permission bits

These bits must match the deployed address. Confirm on-chain before you route.

FAQ

Can I paste this into production? The snippet is an excerpt. Use the full file at the source URL, match flags to the address, and treat this page as a map, not a guarantee.

How do I build this safely? Start with secure v4 hooks and the OpenZeppelin hooks guide.
