1inch Security
Trustless. Secure. Compliant.
Multi-surface screening
All interactions are protected by layered controls: real-time screening (geofencing, VPN, device integrity), on-chain analytics and threat profiles, with manual overrides when needed.
Integrated public blocklists
1inch absorbs reputable sanctions and risk blocklists. Updates sync near-real time across all layers and supported chains.
Cybercrime intelligence
Open-source intelligence and trusted threat signals help pre-flag malicious infrastructure and abuse patterns.
Transaction and behavior pattern monitoring
Behavioral analytics highlight suspicious sequences. Risky actions trigger warnings or extra checks before a transaction is signed.
Internal blockchain investigation team
Security analysts investigate high-risk activity across chains, connect addresses and flows, and feed verified findings into warnings, blocks, and incident response.
Advanced wallet & address screening
Interactions are screened against internal research and external intelligence. High-confidence hits trigger immediate protective controls, followed by a defined human review to minimize false positives.
DeFi risk management
We deploy layered strategies to detect and block addresses connected to illicit activity.

Brand abuse takedowns
Comprehensive surveillance detects any attempt to deceive users by exploiting 1inch's identity - then takes proactive measures to intervene.
Built-in security and threat prevention
1inch infrastructure actively detects and prevents malicious activity, with continuous reviews to ensure ongoing safety.
Transaction scanning. Transactions processed via 1inch applications are scanned to detect fraudulent activity, and the user is alerted automatically.
Domain scanning. When a 1inch user connects to a third-party application, a domain scan is activated, and the user is warned of any potential threat.
Malicious token detection. Token and wallet addresses are checked. Scam tokens masquerading as legitimate ones are instantly detected and flagged to the user.
