Is this token a rug — and can I sell it again? Signed verdicts before you buy, approve, send or sign: token rug/honeypot check with buy-sell tax, honeypot sell-simulation, pre-sign calldata guard (unlimited-approve / setApprovalForAll / drain-in-multicall), wallet risk with sanctions screening, tx preflight, and a launch feed with safety overlays. Plus unique Bitcoin forensics no RPC gives you: money-graph role, whale and exchange fingerprinting, Satoshi-era provenance, validation-gated block anomalies, and broadcast-fee timing. Every response Ed25519-signed and independently verifiable. Pay-per-call USDC on Base — no keys, no accounts, no signup.
