How hookcheck checks a coin

Most Elysium coins trade in Uniswap v4 pools with a hook. A hook is code that runs on every swap. It can take a fee, change the price, or stop a trade. hookcheck reads all of it from the chain and shows you what it found.

The verdict

CLEAN: a sell went through in the live pool, costs are normal, and nothing below needs a second look.

CAREFUL: something is worth reading first, like a tax above 5.5%, an owner who can change rules, a few wallets holding most of the supply, or a sell check that couldn't run.

AVOID: a sell or transfer reverted, costs are 25% or more, most of the pool liquidity was removed, or the owner can mint new supply.

What is checked

Buy and sell. A small buy then a sell run through the real PoolManager and the pool's hook with eth_call. The simulator is placed with a state override, so nothing is deployed or sent. Cost is measured against the pool's own price, so it includes the hook fee, the pool fee and any token tax.

Hook flags. A v4 hook's permissions sit in the last bits of its address. beforeSwapReturnDelta and afterSwapReturnDelta mean the hook can take a cut of swaps.

Token contract. Verified source when the explorer has it, otherwise the function list read from the bytecode. Mint, blocklist, pause and fee setters are tried with a simulated call from the owner, so a power is only shown when the owner can really use it. Upgradeable proxies are named with their admin.

Holders. Top 10 wallets as a share of supply, with the pool, the hook, burn addresses and lockers left out.

Liquidity. Every add and removal on the main pool from ModifyLiquidity events.

Launcher. The wallet that opened the pool, what it holds now, and how its earlier coins on the chain look today.

Locks. Supply locked on hypelock is shown when there is some.

Only what was found

If a read fails or doesn't apply, that line is left out. Every line links to the explorer so you can check it yourself.
