Kill Switch’s Uniswap v4 hook
Kill Switch — HEY ties this Uniswap v4 hook to it: made by the project’s factory.
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
- 0x9cac9e13fc10bc7e620cd3e3d89f82b0d7e41000
- First pool HEY read
- block 76,040,467 (time not read yet)
Who built it, and why HEY says so
- Tied to
- Kill SwitchActive
- On what basis
- Made by the project’s factory
- How
- Made by the project’s factory: a factory the account that launched its token deployed created it, as one of the factory’s instances.
Callbacks its address declares
Called after a pool is created.
afterInitialize— after a pool is created
Decoded from the address itself: what the PoolManager will call, never what the code does and never whether it is safe.
Source
- Verified source
- Not read — HEY has not read the explorer’s source record for this hook.
- Proxy
- Not read — HEY’s contract watch has not checked this address for a proxy.
Uniswap’s hooklist
Uniswap’s public hooklist, as HEY last read it, does not carry this hook. Read 28 Oct.
Pools using it
1 pool on tokens HEY tracks use it, initialised between block 76,040,467 and block 76,040,467.
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.
- 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.
