An exchange-hack check traces whether a wallet received crypto stolen in exchange breaches such as Mt. Gox or FTX-era thefts; Plastron flags exchange-hack fund exposure free across seven EVM chains.

The history of cryptocurrency exchange hacks spans over a decade, from Mt. Gox's collapse in 2014 through the Bybit hack in 2025. Mt. Gox alone resulted in 850,000 BTC stolen, most of which has never been recovered and continues to generate compliance concerns as partial distributions to creditors occur. The 2016 Bitfinex hack produced 119,756 BTC in stolen funds that moved slowly through laundering operations until the 2022 DOJ seizure. The 2020 KuCoin hack produced $281 million in stolen tokens distributed through DEX protocols. The 2025 Bybit hack produced $1.5 billion attributed to Lazarus Group. Each of these hacks left on-chain traces that persist in blockchain analytics databases. Funds from exchange hacks move differently from DeFi exploit funds: exchange hackers often hold stolen assets for years before attempting to launder, making the exposure distribution slower and more diffuse. Stolen exchange funds that have been in circulation long enough to reach ordinary DeFi protocols, P2P trades, or exchange deposits create compliance exposure that can surface years after the original hack. Understanding whether any of your counterparties trace back to major exchange hacks is important for anyone who has been active in DeFi or peer-to-peer trading over the past decade.
