Nietzschean Penguin’s Uniswap v4 hook

0x8fec…6044

Robinhood Chain (4663)

Nietzschean Penguin — HEY ties this Uniswap v4 hook to it: created by the account that deployed a contract the project lists as its own.

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: 0x8fecfbffd5f5e430d3a375c0af0fdb5a458f6044
First pool HEY read: block 41,623,062 (time not read yet)

Who built it, and why HEY says so

Tied to: Nietzschean PenguinNo builder source linked
On what basis: Created by an address linked to the project
How: Created by the account that deployed a contract the project lists as its own: an address linked to the project — the account that deployed a contract the project lists as its own — created it.

Callbacks its address declares

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

beforeInitialize — before a pool is created
afterSwap — after each swap
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

Listed in Uniswap’s hooklist as PonsV2MemeHook

A third-party listing, shown as context: it does not tie the hook to a project. Read 8 Oct at commit a15ee37.

Pools using it

1 pool on tokens HEY tracks use it, initialised between block 41,623,062 and block 41,623,062.

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.
