ADDRESS CHECK · PRE-FLIGHT

Is this payee address safe?

Before you pay, paste the payee address and screen it, free, for sanctions, mixers and scam risk. Usually takes a few seconds. We don't hand you a black-box score: what it hit and why is laid out for you to verify.

Coverage: Ethereum / Polygon / Arbitrum / Base / Optimism / Tron: list hits plus on-chain behaviour analysis (address age, activity, one-hop taint, stablecoin freeze lists). BNB Chain / Avalanche: list hits plus address activity (Avalanche also checks the USDC freeze list). Bitcoin / Solana: verdicts use list matching only; deep trace on request.

By submitting an address you confirm authority to process it. Results are technical risk references, not authoritative legal determinations; no risk signal found ≠ safe.

How is the risk score computed? (0–100)

A 0–100 score (not 1–10): higher = riskier, mapped to three verdicts:

  • 0–29 clear: no list hit, no high-risk signal.
  • 30–69 caution: risk signals present (new address / receive-only / unusual activity), proceed only within your mandate.
  • 70–100 risky · decline: sanctions/mixer/scam list, frozen by Tether/USDC, or one-hop tainted by illicit funds.

Examples: issuer-frozen +92 · list hit → 100 · one-hop taint +60–65 · brand-new empty +24 · new (<7d) +12. Every verdict ships with verifiable evidence.

The other half

Is the URL you are about to call a phishing host?

When an endpoint is spoofed, the payee address it hands back is freshly generated and clean. No address list has ever seen it. This class can only be caught at the endpoint layer.
