Loom’s Uniswap v4 hook

0x4eaf…60cc

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: 0x4eafa1c72ca13c6a9f93095b686afc7dd5bc60cc
First pool HEY read: 29 Sep (block 75,247,269)

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 each swap and after each swap; may change a swap’s amounts before and after it.

beforeInitialize — before a pool is created
beforeSwap — before each swap
afterSwap — after each swap
beforeSwapReturnDelta — may change a swap’s amounts before it
afterSwapReturnDelta — 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

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

Pools using it

1 pool on tokens HEY tracks use it, initialised between block 75,247,269 and block 75,247,269.

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.
