Robinhood Chain (4663)

predict FWA — HEY ties this Uniswap v4 hook to it: confirmed by HEY’s review as the project’s hook (not proven on chain).

What it is

A Uniswap v4 hook contract: the PoolManager calls it at the moments its address declares, in every pool created with it.

Contract: 0x0c9ddd9e45817252d56f70ec015a4e828212a0cc
First pool HEY read: block 83,578,385 (time not read yet)

Who built it, and why HEY says so

Tied to: predict FWAShipping
On what basis: Confirmed by HEY’s review · 22 Oct · not proven on chain
How: Confirmed by HEY’s review as the project’s hook: HEY’s review confirmed it as the project’s; it is not proven on chain, and HEY’s own read would supersede it.

Callbacks its address declares

Called before a pool is created, before each swap and after each swap; may change a swap’s amounts before and after it.

beforeInitialize — before a pool is created
beforeSwap — before each swap
afterSwap — after each swap
beforeSwapReturnDelta — may change a swap’s amounts before it
afterSwapReturnDelta — may change a swap’s amounts after it

Decoded from the address itself: what the PoolManager will call, never what the code does and never whether it is safe.

Uniswap’s hooklist

Uniswap’s public hooklist, as HEY last read it, does not carry this hook. Read 17 Oct.

Pools using it

1 pool on tokens HEY tracks use it, initialised between block 83,578,385 and block 83,578,385.

Pools initialised with the hook on a token HEY tracks (HEY keeps no other pool): a count, the first and last init block, and the pools HEY recorded per UTC ISO week over the last 12 weeks. Context only: never an order, a score or a leaderboard.

Pools HEY recorded, week by week

Counted by when HEY recorded each pool, not by its block time: HEY keeps no block-time mapping. A week before HEY began recording is not zero — nothing was recorded then — and the week it began also holds every earlier pool it read back from the chain.
