• Memecoin/risk
  Memecoin risk verdict for one token on Solana or Base: liquidity counted only against real assets (SOL/USDC, ETH/WETH/USDC), mint and freeze authority, honeypot and sell tax, liquidity lock, holder concentration excluding pools and lockers. One level — LOW, ELEVATED, HIGH, CRITICAL — with every finding behind it; data a source could not supply is reported as unknown, never as a pass. Each verdict is filed as a claim ("loses 90% within 7 days"), anchored on Base and scored publicly at /calibration.
  cryptomarket-datax402
• Memecoin/new
  New memecoin pools on Solana or Base, screened every 15 minutes whether anyone asks or not: the newest pools quoted in a real asset with at least $10,000 of liquidity, each with its risk verdict, the market at screening time, and whether its 7-day claim has resolved yet. This is the population the public track record at /calibration is computed from.
