Index / Full range

Full range

Force v2-style full-range LP: only the hook can modify liquidity, users mint a pool ERC20 instead.

FullRange’s beforeInitialize requires tickSpacing 60 and deploys a per-pool ERC20 receipt. beforeAddLiquidity reverts unless sender is the hook, so LPs must call addLiquidity on the hook (min to max tick). beforeSwap marks that fees have accrued. This is how you wrap a v4 pool as constant-product inventory. UNLICENSED Uniswap example — take the full file, including rebalance/donate dust. Listing is not an audit.

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.
