What is Wallet Risk Check?

Wallet Risk Check is an AI-powered API that screens blockchain wallet addresses for fraud risk. It returns a risk score (0–100), risk level (LOW / MEDIUM / HIGH), and a list of behavioral flags. Pre-calculated scores are returned instantly; fresh recalculation takes 3–4 seconds.

What is the difference between Wallet Audit and Wallet Risk Check?

Wallet Risk Check is a focused fraud-screening endpoint — it returns a risk score (0–100), risk level (LOW / MEDIUM / HIGH), and behavioral flags. Built for fast pre-transaction checks. Wallet Audit returns a full behavioral profile of a wallet in one call: trust score, screening across 18 risk categories, experience level, risk profile, predicted intentions, and transaction breakdown. Use Risk Check for high-throughput screening; use Audit when you need a complete picture of the wallet.

What data does the API return?

Every call returns: a risk score (0–100), a risk level (LOW / MEDIUM / HIGH), a list of behavioral flags across 18 risk categories (money laundering, phishing, mixer usage, darkweb, sanctions, and more), sanctions status (OFAC / EU / UN with source URLs), and a flag indicating whether the result is instant or freshly recalculated. All responses are JSON with timestamps.

Which blockchains are supported?

Currently supported networks: Ethereum, BNB Smart Chain, Base, Polygon, and Tron. ENS address resolution is also supported for Ethereum.

How accurate is the fraud detection?

The underlying AI model achieves 98% predictive accuracy. It is trained on 19.7M wallet behavioral profiles and covers the 95–99% of addresses that traditional rules-based risk tools cannot assess.

Does it require users to submit KYC?

No. Wallet Risk Check works purely on-chain — it analyzes publicly available transaction history and behavioral patterns. No personal data or identity documents are required.

What You Get

One Call. Three Layers of Protection.

A single API request returns a trust score, risk screening across 18 categories, and a sanctions check — with instant results for known wallets.

Forensic Screening

18 risk categories

Every wallet is checked against 18 forensic categories: money laundering, phishing, mixer usage, cybercrime, darkweb transactions, sanctions, fake KYC, honeypot, and more. If any flag is detected — trust score drops to 0% automatically.

Sanctions Check

Regulatory compliance

Cross-references the wallet against OFAC, EU, and UN sanctions lists. Returns sanction status, category, entity name, and source URL. Built for compliance teams that need an audit trail.

Predicted Trust Score

AI-powered risk signal

A single score from 0 to 100% calculated by a predictive AI model trained on 19.7M wallet profiles. 98% accuracy on Ethereum, 96% on BNB Chain. Wallets with fewer than 10 transactions get a "New Address" flag — treat with caution.
