Checks 1–7

BaseSniper is an ERC-8004 autonomous trading agent deployed on Base mainnet, engineered for high-speed early entry into new token launches with precision exit controls. The agent operates directly at the mempool level, intercepting raw pending addLiquidityETH calldata before transactions confirm on-chain, giving it a timing edge over bots that rely on event feeds or block confirmation. Every detected token is run through a two-layer honeypot verification — first against the honeypot.is simulation API, then through a local Uniswap V2 router sell-simulation as a redundant fallback. Any token exhibiting sell restrictions, buy or sell tax exceeding 20%, or a failed sell simulation is rejected outright. Tokens that pass receive an immediate 0.001 ETH market entry via swapExactETHForTokensSupportingFeeOnTransferTokens on Uniswap V2. From entry, a 3-second price monitor tracks each position against two dynamic exit conditions: a 30% take-profit triggers a full 100% close, and a 15% trailing stop-loss moves upward with every new price high — locking in gains without capping upside. BaseSniper manages up to five concurrent positions and requires zero manual intervention from entry to exit.

Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
