V5 is the current protocol version for LFG.RICH. V3 still exists for legacy tokens, but new integrations should use V5 by default.

​
What changed

​
Dynamic token context

Legacy tokens may report old factory or hook addresses through FACTORY() and hook(). New integrations should read those values from the token and use them when present.

​
Do not hardcode PoolKey

Hardcoding PoolKey values can make swaps fail because PoolManager expects the exact initialized pool. Always call factory.getPoolKey(tokenAddress) using the correct Factory.

​
V5 price scaling

V5 prices are scaled by 1e22. If your integration divides V5 price values by 1e18, token prices, market caps, borrow estimates, and PnL can appear 10,000x too high.
