# Address Screening

Taurox implements wallet address screening to prevent access from addresses associated with illicit activity. The screening process is designed to meet regulatory compliance requirements while preserving user privacy.

## How Screening Works

When a user connects a wallet to the Taurox protocol, the wallet address is submitted to a third-party blockchain intelligence provider for risk assessment. The screening service evaluates the address against known databases of flagged wallets, sanctioned entities, and illicit activity patterns. Addresses that exceed the risk threshold are denied access to the protocol.

Screening occurs at the point of wallet connection. It does not continuously monitor user activity after access is granted.

## Privacy Protections

The screening process is designed to minimize data exposure:

**No IP Sharing.** The user's IP address is not transmitted to the third-party screening provider. The protocol routes the screening request through a proxy endpoint that forwards only the wallet address.

**No Additional Metadata.** Only the wallet address is submitted for screening. No transaction history, balance data, personal information, or device identifiers are included in the request.

**No Data Retention.** The protocol does not store screening results beyond the immediate access decision. The screening provider's data handling is governed by its own privacy policy.

## Compliance

Address screening supports the protocol's compliance with applicable sanctions regulations and jurisdictional requirements, including OFAC (Office of Foreign Assets Control) designations. Blocking access from flagged addresses reduces the protocol's exposure to regulatory liability and protects users from interacting with compromised or sanctioned counterparties.

## Screening Provider

The protocol integrates with established blockchain intelligence providers that maintain comprehensive databases of flagged addresses. The specific provider and risk threshold parameters are configurable through governance, allowing the DAO to adjust the screening framework as regulatory requirements evolve.

## Limitations

Address screening is a preventive measure, not a guarantee. Sophisticated actors may use new or unlisted addresses to circumvent screening. The protocol treats screening as one layer in a broader compliance and security framework rather than a standalone solution.
