Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Safe to sign? EVM/Solana/XRPL/Algorand/Stellar txs, permits, tokens; OFAC screen: green/orange/red
CabalLens exposes why 94% of Solana meme-coin traders lose money even on tokens passing static contract checks (RugCheck 100/100). Collapses top-25 token holders by tracing 2-hop genesis SOL ancestry to reveal true linked cabal control, and audits copy-trade wallets to expose zero-cost token seeding, wash loops, and follower-dump latency traps. Zero upstream paid APIs, free $0.00 peek triage, and $0.005 deep proof settled natively via x402 USDC or bearer keys.
