Feyn is live scam detection for Solana's trenches. It watches every pump fun and PumpSwap trade in real time and flags rugs, bundled launches, wash trading, fake holders and mixer-funded wallets, with the on-chain proof behind every verdict. The scanner is free on the website and Telegram. Bots, terminals, wallets and AI agents pay per request via x402, and 50% of every payment buys and burns $FEYN. More usage, less $FEYN. Check before you buy.
