A Uniswap v4 hook contract whose address declares 4 callbacks, first read initialising a pool at block 76,905,184. HEY attributes it to flipper-contracts: the account that launched its token created it through a deterministic deployer.

What it is: Uniswap v4 hook
Callbacks its address declares: beforeInitialize, beforeAddLiquidity, beforeSwap, beforeSwapReturnDelta. What the PoolManager will call, not what the hook does.

Attributed to: flipper-contracts: the account that launched its token created it through a deterministic deployer
The deployment: The follow-up deployment record

When it happened: 2026-09-30, dated by the source to the minute
HEY first saw it: 2026-10-01 (2d ago)These are two different clocks: when the work happened, as the source dates it, and when HEY first read it.
How it is backed: Publicly verified
Counts toward building: Yes. It is one of the records HEY’s activity status is built from.
What it does not say: A contract record says what the chain shows about a contract. It is not a safety check, and it does not say who runs the contract.
