What is Sanctions Screening?

Sanctions screening is the process of checking whether a transaction involves entities on government sanctions lists. It is a mandatory compliance requirement for regulated platforms and prevents funds from reaching prohibited individuals, entities, or countries.

How does Sanctions Screening work?

  1. A user initiates a transaction on a regulated platform.
  2. The platform extracts the wallet address and checks it against OFAC, EU, and UN sanctions lists.
  3. If the address matches a sanctioned entity, the transaction is automatically blocked.
  4. All screening results are logged for audit purposes.

Why does Sanctions Screening matter?

It prevents regulated platforms from becoming conduits for money laundering, terrorism financing, or sanctions evasion. Non-compliance can result in severe fines and loss of operating licenses.
