Description
Sentry is a non-custodial, multi-chain crypto wallet enhanced with an AI security layer that monitors every approval and transaction. Acting as a real-time firewall, SentryAI scans wallet interactions to identify phishing links, malicious smart contracts, address poisoning, and known drainer patterns. Instead of exposing users to raw transaction data, the platform translates complex blockchain actions into clear, understandable risk summaries. Private keys remain encrypted on the user’s device, ensuring that security analysis does not compromise ownership or control. When suspicious behavior is detected, features like the Emergency Panic Vault help prevent further losses. The wallet supports major blockchain ecosystems including EVM networks, Bitcoin, and Solana, creating a unified security experience across chains. Users can also export a visual Recovery Card for safer backup management. Live security prompts provide actionable recommendations before transactions are finalized. The built-in SentryAI engine combines on-chain intelligence with real-world incident patterns to explain the “why” behind each warning. Designed for proactive defense rather than reactive recovery, Sentry empowers users to avoid costly mistakes before they happen.
