Cross-chain address & counterparty risk — one call before you send to, approve, or trust an address. EVM chains (ethereum, base, bsc, polygon, arbitrum, optimism, avalanche, …): sanctions, mixer, phishing, drainer, money-laundering & cybercrime flags aggregated from GoPlus, told whether it's a contract or a wallet. XRP Ledger (r-addresses): Cerberus's own engine — the production rug blocklist, live clawback/global-freeze flags (can this address seize or freeze tokens it issues?), burn-address detection, and prior launch history — coverage no incumbent offers. Chain is auto-detected; pass `chain` to pick the EVM network (default ethereum). Verdict: high_risk | caution | safe | unknown, source named. Price: $0.008 USDC. Missing something?
