An Ethereum wallet check screens an ETH address for sanctions, mixer and stolen-fund exposure that could freeze an exchange deposit; Plastron checks Ethereum wallets free in seconds, no signup, with no custody of your funds.

Ethereum processes over a million transactions daily. Among those are interactions with sanctioned smart contracts, mixer deposits, and addresses tied to protocol exploits worth billions. The OFAC SDN list targets more Ethereum addresses than any other blockchain — Tornado Cash alone added dozens. If your wallet touched a flagged contract through a DEX aggregator or received tokens from a compromised address two hops back, your next centralized exchange deposit could trigger a freeze. Compliance teams at Coinbase, Binance, and Kraken run automated checks on every incoming ETH transfer. They see what you cannot: the full graph of your counterparty exposure. A single indirect link to a sanctioned entity is enough to lock your funds for months while their compliance department investigates. Plastron runs the same analysis they do, but puts it in your hands first.
