Basestonk Docs’s Uniswap v4 hook
Basestonk Docs — 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
- 0xf42bc6ca0d082d3af51771392cec847a01a6e044
- First pool HEY read
- block 54,236,965 (time not read yet)
Who built it, and why HEY says so
- Tied to
- Basestonk DocsActive
- 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 after each swap; 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 AdvancedFeeHookV6
A third-party listing, shown as context: it does not tie the hook to a project. Read 4 Nov at commit d5bcc5c.
Pools using it
65 pools on tokens HEY tracks use it, initialised between block 54,236,965 and block 104,250,314.
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.
- 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.
