A pre-deposit crypto check screens your wallet for sanctions, mixer and scam exposure before you send funds to an exchange; Plastron runs that check free in about 30 seconds, with no signup and no custody.

A pre-deposit crypto check is exactly what it sounds like: screening your wallet for AML risk before depositing to a centralized exchange. Despite being the single most effective way to avoid a compliance freeze, it is almost never done because the tools have historically been expensive or inaccessible. The reason the check matters is that exchanges run automated blockchain analytics on every incoming deposit. These systems trace fund flows across your wallet's counterparty graph, flag interactions with OFAC-designated addresses and known mixer contracts, and assign a risk score to the depositing wallet. The entire process happens before your deposit is credited — sometimes before it is even confirmed. If the system flags your wallet, your deposit goes to a manual review queue. If the manual review team decides the exposure is significant, your account is placed on hold and a source-of-funds request is issued. The investigation that follows is slow, frustrating, and not guaranteed to resolve in your favor. Most users who go through this process describe it as weeks of back-and-forth communication with a compliance team that cannot tell them what triggered the review or when it will end. The information asymmetry is severe: the exchange has full visibility into your wallet's risk profile before you deposit, and you have none. Running a Plastron pre-deposit check closes that gap. It takes about 30 seconds, it is free, it requires no account or wallet connection, and it shows you exactly the risk flags that an exchange compliance system will see when it scans your wallet. Wallets with Low scores can deposit with confidence. Wallets with Medium to High scores can investigate the specific counterparties driving the score before deciding whether to proceed or take steps to clean up their risk profile first.
