Robinhood Chain hooks
The hook address on a Uniswap v4 pool says which callbacks the pool manager will call. These are the hooks inside swaps on chain 4663. Prices for the same pools are on Robinhood Chain pools.
About this desk
- What you use it for
- See which Uniswap v4 callbacks a hook on Robinhood Chain runs, and which pools use it.
- What the numbers are
- The lowest 14 bits of the hook address are the callback permissions. The list is hooks inside Universal Router swaps in the newest blocks. Bytecode length is read from the address. A pasted address is decoded even when it did not trade in this window.
- What it leaves out
- A hook that has not been in a scanned swap is absent until you paste it. The bits say which callbacks are allowed, not the Solidity source. A delta callback can change the amount you receive. This is chain 4663, not the $VEXUNO ledger.
Every desk is introduced the same way on the desk list.

How to read this
- The bits
- Uniswap v4 stores the callback permissions in the lowest 14 bits of the hook address. Before and after initialize, liquidity, swap, and donate are separate bits. A delta bit means that callback can change the amounts. The pool manager calls the hook only for the bits that are set.
- What this page reads
- The pools come from Universal Router swaps in the newest blocks. The bytecode length is eth_getCode. A pasted address is decoded the same way, even when it did not trade in this window. The quote on Robinhood Chain pools already passes this hook into the quoter.
