Opportunity 3: JIT-via-Hook Liquidity
V3 JIT (just-in-time) liquidity required searchers to wrap a swap with mint and burn in the same block. V4 hooks let a pool internalize JIT — the hook itself adds and removes liquidity around incoming swaps, capturing the LP fees.
For an external searcher, this changes the strategy:
- Pools with internal JIT hooks are harder to JIT-attack — the hook already takes the LP fee. Don't waste gas competing.
- Pools without internal JIT still allow classic V3-style JIT, but you must check the hook flags first (
hasPermission(BEFORE_ADD_LIQUIDITY_FLAG)) to know whether your mint will trigger extra callbacks.
The on-chain check is one storage read. Skip pools where internal JIT is active and focus capital on the half of the market without it. See for the calculation framework.
