How this service works
Scan any EVM wallet address or ENS name for on-chain risk signals using Web3 Antivirus. Returns a toxic score, risk level, and the specific risk categories that triggered a flag. Designed for off-ramp compliance: use shouldFlag to block or escalate — any non-zero toxic score means the wallet has been flagged for at least one risk category such as sanctions, scams, mixers, or phishing.
Output
Returns a normalized toxic score (0–1), a risk level enum (PASS/LOW/MIDDLE/CRITICAL), a boolean shouldFlag indicating whether the wallet should be blocked, a list of flagged risk categories (e.g. known_scammer, sanction_address, mixer, rug_pull), whether the address is a smart contract, whether it has on-chain history, and the resolved ENS name if available.
Example use cases
Verify customer wallet before crypto transfer
“I'm about to send funds to this ENS name vitalik.eth for a client. Can you quickly check if that wallet address has any red flags or risk signals I should know about before we proceed?”
Compliance screening for exchange withdrawal
“A user just requested to withdraw to wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f6bEb0. Can you scan this address for any sanctions, mixer involvement, or scammer activity to make sure it's safe for us to process?”
Detect compromised wallet in transaction
“This wallet tried to interact with our protocol and made some suspicious transactions. Run a risk assessment on 0x1234567890123456789012345678901234567890 to see if it's been compromised or is involved in any known scams or phishing schemes.”
Technical details
Endpoint
GEThttps://scan.madhousewallet.com/api/public/scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain wallet risk assessment specifically for EVM-compatible addresses and ENS names, especially for off-ramp compliance where any non-zero toxic score must trigger a block or escalation. Prefer this over generic sanctions screening (like OpenSanctions) when the subject is a crypto wallet address rather than a named person or entity, and when you need Web3-specific signals like mixer usage, rug pull involvement, phishing, or scam transaction initiation.
Side effects
- Invalid or malformed address returns an error — address must be 0x-prefixed checksummed EVM address or valid ENS name
- Unknown or brand-new address with no on-chain history may return addressExists: false with a zero toxic score
- API may return raw integer scores 0–100 for confirmed bad actors instead of normalized 0–1 — caller must normalize
- Payment failure or insufficient USDC balance results in x402 payment required error
- ENS resolution failure if ENS name is unregistered or resolution service is unavailable
