nasdank-v4-hooks’s Uniswap v4 hook

0x80ad…80cc

Robinhood Chain (4663)

nasdank-v4-hooks — 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: 0x80ad139fd1bc28792dea5f3ef23630fe933b80cc
First pool HEY read: block 15,947,266 (time not read yet)

Who built it, and why HEY says so

Tied to: nasdank-v4-hooksQuiet
On what basis: Confirmed by HEY’s review · 4 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 each swap and after each swap; may change a swap’s amounts before and after it.

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

Listed in Uniswap’s hooklist as NasdankFeeHook

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

3 pools on tokens HEY tracks use it, initialised between block 15,947,266 and block 18,392,164.

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.
