| Customization | None | Hooks: plug-in contracts that change pool behavior |
| Multi-hop gas | Tokens move between every pool | "Flash accounting" settles only net balances: lower gas |
| Native ETH | Must wrap to WETH | Native ETH supported |

Estimate impermanent loss and fees for a concentrated-liquidity position (same math for v3 and v4).
Estimates only, not financial advice. Fee estimate assumes the price stays in range, volume is spread evenly, and nearby liquidity is like yours. Actual results vary.
Hooks are plug-ins that change how a v4 pool works. Common types:
Raises fees in volatile markets and lowers them in calm ones, to protect liquidity providers.
Fills an order automatically when the price crosses your target.
Splits big orders into small trades over time to reduce price impact.
Reduces sandwich attacks and returns value to liquidity providers.
Limits trading to approved wallets, for tokenized stocks and real-world assets.
Moves your range automatically to keep earning when the price drifts.

A simple checklist before you move a position.
Check that the v4 pool for your pair has enough volume and liquidity. A thin pool earns less.
If the pool uses a hook, read what it does and whether it has been audited.
Collect fees, remove v3 liquidity, then add to v4 with a range modeled in the calculator above.
