# What is on-chain transaction screening?

> Learn about Spring's screening processes for wallet addresses and transactions to ensure compliance.

All wallet addresses that interact with the Spring platform undergo screening against OFAC crypto-specific sanctions to prevent engagement with individuals or organizations linked to illegal activities.

Spring performs additional on-chain examinations of wallets and transactions for investors flagged as high-risk. This process involves tracing the origin and flow of funds and comparing them against risk categories to determine exclusion eligibility.

## Risk Areas Covered

The screening covers several risk areas:

* Sanctions exposure
* Money laundering and financial crime
* Links to terrorism and terrorist organizations
* Other illegal or illicit activities and content
