Loom’s Uniswap v4 hook

0x37c8…6080

Robinhood Chain (4663)

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: 0x37c86e92a081ae0c1d3ad2ea5b0bb58f56546080
First pool HEY read: 17 Sep (block 65,736,667)

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 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

Verified source: The explorer holds no verified source for it.
Proxy: HEY’s contract read detected no proxy at this address.

Uniswap’s hooklist

Uniswap’s public hooklist, as HEY last read it, does not carry this hook. Read 8 Oct.

Pools using it

6 pools on tokens HEY tracks use it, initialised between block 65,736,667 and block 65,771,725.

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.
