How do I check if a crypto wallet is safe?

Paste any wallet address into CryptoCheq's scanner. We run 35+ on-chain checks — including OFAC sanctions screening, threat intelligence cross-reference, DeFi exposure analysis, behavioral fingerprinting, and an AI-powered risk model — and return a composite risk score with plain-language explanations.

What is a blockchain wallet risk score?

A risk score (0–100) reflects the overall safety of a wallet. Scores above 70 indicate low risk; scores below 40 indicate high risk. The score aggregates 35+ heuristics including sanctions exposure, threat intel reports, DeFi liquidation risk, approval footprint, and behavioral fingerprinting.

Which blockchains does CryptoCheq support?

CryptoCheq supports 9 blockchain networks: Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Solana, Bitcoin, and Tron.

How does transaction simulation work?

CryptoCheq simulates any EVM transaction off-chain and shows you the exact outcome — which assets would move, which approvals would be granted, whether the counterparty is risky, and whether the contract is a honeypot — before you commit on-chain.

What is OFAC sanctions screening for crypto?

OFAC (Office of Foreign Assets Control) maintains lists of sanctioned individuals and entities. CryptoCheq cross-references wallet addresses against the SDN list and other global sanctions databases to flag wallets linked to sanctioned parties.

How do I check token approvals for my wallet?

Use CryptoCheq's Token Approval Checker: enter your wallet address, select the chain, and we fetch every active ERC-20 approval. Unlimited allowances and high-risk spender contracts are highlighted immediately.

How do I detect a honeypot smart contract?

CryptoCheq's Contract Inspector simulates buy/sell transactions against the contract bytecode, checks GoPlus token security data, and analyzes owner privileges to detect contracts that prevent selling, implement hidden fees, or are otherwise designed to trap funds.

Is it free to scan a wallet on CryptoCheq?

Basic wallet scanning is free during beta. Scan credits start at $1/scan with no subscription required — credits never expire. See our Pricing page for full details.

What is behavioral fingerprinting in blockchain security?

Behavioral fingerprinting analyzes on-chain patterns — transaction timing, counterparty diversity, gas usage, DeFi interaction history, and mixing service usage — to classify a wallet into a risk persona (e.g., DeFi Trader, Dormant Whale, Bridge Hopper). Unlike sanctions lists, it catches wallets that behave suspiciously even without prior flags.

What is a peeling chain attack in crypto?

A peeling chain is a money-laundering technique where funds are passed through a rapid sequence of single-use wallets, "peeling" small amounts at each hop to obscure the origin. CryptoCheq detects peeling chain patterns by analyzing counterparty graph structure and hop velocity in transaction histories.

How accurate is the CryptoCheq risk score?

The risk score combines 35+ deterministic checks (sanctions, threat intel databases, honeypot detection) with an ML model trained on labeled wallet data. Sanctions and threat intel signals are high-confidence; behavioral signals carry lower weight individually but compound. The score is informational — always review the underlying signals for compliance decisions.

Can I use CryptoCheq API for AML and compliance screening?

Yes. The CryptoCheq REST API returns structured risk data — sanctions exposure, risk score, threat intel matches, and behavioral signals — in JSON format. API key access unlocks at the 100-scan pack ($80 one-time). Enterprise packs include higher rate limits, team seats, and SLA — suitable for exchange onboarding and compliance automation.

WIE VERLUSTE ENTSTEHEN

Der Verlust beginnt vor der Überweisung.

Eine überzeugende Rendite, eine vertraut wirkende Adresse, eine scheinbar normale Freigabe. Solche Muster führen immer wieder zu echten Krypto-Verlusten.
