Loom’s Uniswap v4 hook
Loom — HEY ties this Uniswap v4 hook to it: deployed by the account that launched the project’s token, through a deterministic deployer.
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
- 0x3ad87f5b9cf8f17ed39d787eef3d9d19053d28cc
- First pool HEY read
- 30 Sep (block 76,644,461)
Who built it, and why HEY says so
- Tied to
- LoomShipping
- On what basis
- Proven on chain
- How
- Deployed by the account that launched the project’s token, through a deterministic deployer: the account that launched its token created it through a deterministic deployer.
Callbacks its address declares
Called before a pool is created, before liquidity is added, before each swap and after each swap; may change a swap’s amounts before and 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
Uniswap’s public hooklist, as HEY last read it, does not carry this hook. Read 8 Oct.
Pools using it
2 pools on tokens HEY tracks use it, initialised between block 76,644,461 and block 76,676,909.
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.
