12mo FeeHookCharges a 10% fee on every swap by computing the fee on the output token (exact-in) or input token (exact-out) amount and minting it as ERC-6909 claims to a fixed fee recipient address via afterSwapReturnsDelta. Base afterSwapafterSwapDelta 1 12mo TELxIncentiveHookTracks LP positions and fee accruals in an external PositionRegistry to support off-chain incentive/reward distribution. Liquidity callbacks are restricted to an authorized position manager address; no swap logic is implemented. Base beforeInitafterAddLiqafterRemoveLiq 1 12mo PhiEthHooksImplements a custom 1:1 ETH/phiEth swap curve that bypasses AMM concentrated liquidity: in beforeSwap, the hook takes the full input from the PoolManager, calls phiEth.deposit or phiEth.withdraw to convert tokens, then settles the full output, returning a delta that no-ops the standard AMM. Direct liquidity addition is blocked. Base beforeInitbeforeAddLiqbeforeSwapswapDelta 1 12mo PhiEthHooksImplements a custom 1:1 ETH/phiEth exchange hook that routes swaps through the phiEth wrapper contract (minting phiEth on ETH input, burning on phiEth input), while blocking direct liquidity additions to the pool.
