What is Address Screening

Address screening helps identify fraud and malicious addresses before a destination address is whitelisted or a transaction is executed, preventing financial and compliance risks.

Liminal has integrated with Cube3 and Cyvers to evaluate addresses for fraud and cyber security related risks by screening destination addresses. Address screening has the following features:

• Automated risk evaluation - In Liminal Vaults web and mobile app, when you initiate address whitelisting, approve address whitelisting policy, initiate transactions, and sign transactions, a risk score (low,medium, high, critical) is displayed based on the risk severity. You can make informed decisions and prevent losing funds to malicious addresses.
• API security for withdrawal hot wallets - All destination addresses passed in the request body of the Create transaction requests API will be screened by Cube3 for Cyber, Fraud and Compliance related risks.
• Personalised risk score severity settings - Configure personalised severity range for automatically blocking risky transactions. All risky transactions irrespective of severity will display a warning before approving or canceling the transaction if the settings have been set to “warn only”.

Liminal has partnered with Cube 3 and Cyvers to evaluate your addresses and transactions which are described as follows:

• Cyvers - analyses addresses to identify connections with risky entities, assigning them a risk score to help detect potential threats and ensure safe transactions. It detects potential risks under security, scam, and compliance categories as explained below:
  • Security: Real-time threat detection and prevention for blockchain assets.
  • Scam: Identifying fraudulent transactions and phishing attacks.
  • Compliance: Helping crypto firms meet AML and risk management requirements.
• Cube3 - assigns dynamic risk scores to addresses, smart contracts, and transactions using AI-driven analysis, detecting cyber, fraud, and compliance related risks as explained below:
  • Cyber: Securing blockchain networks from threats like hacking and smart contract exploits.
  • Fraud: Illicit activities such as phishing scams in blockchain transactions.
  • Compliance: Ensuring adherence to regulations (e.g., AML, KYC, Travel Rule) in blockchain operations.

How Address Screening works in Liminal

Address screening via Cube3 and Cyvers will be eventually available at every touch point on the platform such as whitelisting, quorum approvals, transaction initiation and signing for cold multisig, warm mobile MPC wallets and Hot withdrawal wallets.

However, currently the following actions support address screening

1. Whitelist a destination address and Whitelist Approvals (See Section ➡️ Information (Security Screening))

2. Sign MPC transaction on your mobile(See Section ➡️ Information (Security Screening))

3. Create a Hot Wallet transaction request via Liminal Express(See Note for Address Screening and Example Error Response)

📘

Important Note

• You can set customised thresholds to auto-block transactions or warn you depending on the severity of the risk associated with the transaction. See Address Screening Settings.
• Address screening cannot be disabled for Cold Multisig and Warm MPC Mobile Wallets
• Address screening can be disabled for hot withdrawal wallet transactions created via Create a Transaction Request API
