Sudo Cat — HEY ties this Uniswap v4 hook to it: created by the account that launched the project’s token, before the token.

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
0xa35ebc56f0a1cb4762eabd788dad8606667da0cc

block 59,426,320 (time not read yet)

Who built it, and why HEY says so

Tied to
Sudo CatNo builder source linked
On what basis
Created by an address linked to the project
How
Created by the account that launched the project’s token, before the token: an address linked to the project — the account that launched its token — created it; listed, not counted as a follow-up deployment.

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.

Source

Not read: HEY has not read the explorer’s source record for this hook.

Uniswap’s hooklist

Listed in Uniswap’s hooklist as SudoCatHook · listed as dynamic fee

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 59,426,320 and block 59,426,320.

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.

What HEY does not know

  • Routing allowlist: not known. Whether a router or aggregator routes swaps through this hook: HEY reads no routing allowlist.
  • Audit: not known. Whether its code was reviewed by an auditor: HEY reads no audit report for this hook, and a callback list is never a safety verdict.
  • Dynamic fee, from the chain: not known. Whether its pools use a dynamic fee: HEY does not keep a pool’s fee field. Uniswap’s hooklist lists it as dynamic fee — a third-party listing, not a chain reading.
  • Upgradeability: not known. Not read: HEY’s contract watch has not checked this address for a proxy.
  • Verified source: not known. Not read: HEY has not read the explorer’s source record for this hook.
  • First pool’s time: not known. HEY holds the first pool’s block, not its time.
