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. It usually takes a few seconds. We list what it hit and why, so you can check it yourself.

Coverage: Ethereum / Polygon / Arbitrum / Base / Optimism / TRON / BNB Chain / Arc: list hits plus on-chain behaviour analysis (address age, activity, one-hop taint, stablecoin freeze lists). Avalanche: list hits plus address activity; Avalanche also checks the USDC freeze list. Solana / Bitcoin / XRP Ledger / Monero / Bitcoin Cash / Litecoin / BNB Beacon Chain: 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)

The score runs from 0 to 100. Higher means riskier, and it maps to three verdicts:

  • 0–29 clear: no list hit, no high-risk signal.
  • 30–69 caution: risk signals present: new address, receive-only, or 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?

A fake payment page hands you a freshly created address that no address list has seen. Only a check on the URL itself catches this: is it on a phishing list, and is it pretending to be a brand you trust?
