v4 Builder’s Uniswap v4 hook

0x173f…9280

Robinhood Chain (4663)

v4 Builder — 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: 0x173f9af01270f7c99ad2b4d6c17c248e96d09280
First pool HEY read: block 100,222,941 (time not read yet)

Who built it, and why HEY says so

Tied to: v4 BuilderNot measuredNo builder source linked
On what basis: Made by the project’s factory
How: Made by the project’s factory: a factory the project lists as its own contract created it, as one of the factory’s instances.
Made by: 0x227a…bf4a0x227a41c9b869f7ce396337c88ffd0226917abf4a
The project lists the factory as its own contract.An instance is the factory’s product in use: it is not the project’s shipping and never changes its activity status.

Callbacks its address declares

Called after a pool is created, before liquidity is removed and before each swap.

afterInitialize — after a pool is created
beforeRemoveLiquidity — before liquidity is removed
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.

Uniswap’s hooklist

Uniswap’s public hooklist, as HEY last read it, does not carry this hook. Read 29 Oct.

Pools using it

1 pool on tokens HEY tracks use it, initialised between block 100,222,941 and block 100,222,941.

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.
