How Sniff works

The site calls checkV4 or checkV3 on the SniffCheck contract with eth_call, lending the call a HYPE balance. Inside one call the contract buys the coin in its deepest supported pool, sends 10% of it to a fixed sink address, sells the rest, and then reverts with a report. The chain is left exactly as it was.

The test size is 0.2% of the HYPE side of the pool, between 0.001 and 1 HYPE.

• Plain transfer keeps: what the sink received of the 10% sent. Below 100% means the coin taxes transfers.
• Round trip lost: 1 minus HYPE back ÷ HYPE that went into the sold part.
• Missing beyond fees: what was lost on top of the pool's fee both ways and the price impact of the test size.
• Owner: the coin's owner(), if it has one. Renounced means it's the zero or dead address.

The result is Can't sell if the sale reverted, Taxed if a transfer keeps under 95% or more than 10% is missing beyond fees, otherwise Sells fine.

• A coin can behave differently for different wallets or later in time. A test trade only shows now, for a fresh address.
• Only Uniswap v4 and the KleosSwap, ElysPump and Stockium v3 pools can be traded through.
• Not advice and not an audit of the coin.
