Fables’s Uniswap v4 hook

0x594e…a080

Robinhood Chain (4663)

Fables — 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: 0x594e8e6281edf2d363a0293a50004cf868e7a080
First pool HEY read: block 54,583,584 (time not read yet)

Who built it, and why HEY says so

Tied to: FablesShipping
On what basis: Confirmed by HEY’s review · 4 Nov · 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 and before each swap.

beforeInitialize — before a pool is created
beforeSwap — before each swap

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

Source

Pools using it

10 pools on tokens HEY tracks use it, initialised between block 54,583,584 and block 101,581,740.

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.
Published source code: 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.
