|---|---|---|---|
| 2020 | KuCoin | $281 million | In September 2020, KuCoin, a global cryptocurrency exchange, experienced a significant security breach. Hackers accessed the private keys to KuCoin’s hot wallets, resulting in the theft of $281 million in Bitcoin, ERC-20 tokens, and other cryptocurrencies. The exchange worked with various blockchain projects to freeze and recover a substantial portion of the stolen assets. |
| 2021 | Poly Network | $610 million | In August 2021, Poly Network, a decentralized finance (DeFi) platform, was hacked.

This breach underscored the vulnerabilities in cross-chain protocols. |
| 2022 | Ronin Network | $625 million | In March 2022, Ronin Network, the blockchain behind the popular play-to-earn game Axie Infinity, suffered a massive security breach.
