Reading a pool before you trade

The four questions to answer before your first swap.

  1. Is this the right token? Check the address and chain, never the ticker.
  2. What can the hook do? Decode its permission bits.
  3. What does a buy cost me, now and after any opening window?
  4. Can the liquidity disappear?

On Rule Craft every pool page answers all four. For any other v4 pool, the scanner answers the second and gives a risk read.
