Before depositing to KuCoin, screen your wallet for sanctions and mixer exposure that could freeze your funds; Plastron runs an equivalent free, non-custodial check across seven EVM chains, no account needed.

In September 2020, KuCoin's hot wallets were compromised and approximately $281 million in cryptocurrency was stolen. While KuCoin eventually recovered around 84% of the stolen funds through a combination of law enforcement cooperation and project-level token swaps, hundreds of millions in assets remained unrecovered and continued to move on-chain for months afterward. Blockchain analytics firms tagged these addresses and exchanges including Binance and Huobi froze accounts that received the stolen funds. For ordinary users, the KuCoin hack created a long tail of exposure: wallets that traded tokens during the recovery period, received distributions from pools the attacker interacted with, or simply bought tokens that the hacker had dumped may carry KuCoin hack exposure in their counterparty history. Beyond the historical hack, KuCoin applies standard AML screening to all deposits under its regulatory obligations. As the exchange has expanded to serve over 30 million users across 200 countries, their compliance infrastructure has grown to include automated blockchain analytics and documentation requests for flagged deposits. Screening before you deposit is essential.
