PEP screening checks whether a wallet links to politically exposed persons who warrant enhanced due diligence; Plastron focuses on on-chain AML and sanctions risk free across seven EVM chains, not name-based PEP-database matching.

Politically Exposed Persons — government officials, their immediate family members, and close associates — are classified as high-risk AML subjects under FATF guidelines and implemented into law across most regulated jurisdictions. Regulated financial institutions, including cryptocurrency exchanges, are required to apply enhanced due diligence to PEP-linked accounts and to screen for PEP exposure in depositing wallets. In the cryptocurrency context, PEP exposure arises through several channels: direct transactions with crypto addresses linked to government officials or sanctioned oligarchs, receipt of funds from government-controlled enterprises in jurisdictions subject to comprehensive sanctions (Iran, North Korea, Russia under specific designations), and interactions with addresses that have been publicly identified as being controlled by OFAC-designated PEPs. Russia's 2022 sanctions expansion added dozens of oligarchs and their associated cryptocurrency addresses to the OFAC SDN list — and these individuals had historically used crypto exchanges and DeFi protocols for large-value transactions. A wallet that transacted with any of these addresses before the OFAC designation may carry historical PEP-related sanctions exposure. Beyond Russia, Venezuela, Iran, North Korea, and other comprehensively sanctioned jurisdictions have government and PEP-linked crypto addresses on the SDN list. Understanding whether any of your counterparties fall into PEP or sanctions categories is essential for compliance at exchanges that take these requirements seriously.
