What is 1inch Shield
When using the 1inch dApp, you may encounter warning messages while interacting with or exporting custom tokens. These alerts are designed to protect you from risky or malicious assets.
Token checks are handled by 1inch Shield, a security framework that currently integrates Web3 Antivirus for real-time threat detection, with support for additional providers planned in the future.
Why are you seeing a warning?
The warning messages are triggered when a token you are trying to export or interact with falls outside of the 1inch whitelist. Tokens that aren't verified undergo a real-time risk assessment and are classified based on their risk level.
These warnings are not errors—they are security alerts to help you make informed decisions.
How 1inch Shield works
The Token Risk Checking System scans every custom token using multiple indicators, and based on its threat profile, assigns one of the following categories:
Sanctioned token
A token is associated with sanctions or other regulatory restrictions. The user is blocked from any action with this token. They receive a corresponding warning.
Restricted token
A token is restricted and cannot be swapped in the 1inch dApp. The user is blocked from swaps involving this token. They receive a corresponding warning.
Malicious token
A token has been flagged as malicious by the 1inch Shield. The user receives a warning strongly discouraging them from transacting with the token. Still, the technical ability to transact with the token remains available, and the user may proceed at their own risk.
Suspicious token
A token has been flagged by the 1inch Shield due to its malintent or association with spam activities. The user receives a corresponding warning but may proceed to transact with it at their own risk.
Availability-risk token
A token is not available on reputable centralized exchanges and platforms. The user receives a corresponding warning but may proceed to transact with it at their own risk.
Unverified token
A token has not been identified as verified or high-reputation by the 1inch Shield. The user receives a corresponding warning but may proceed to transact with it at their own risk.
