According to a new report by crypto data aggregator Token Terminal, approximately 50% of exploits in decentralized finance, or DeFi, occur on cross-chain bridges. In two years’ time, more than $2.5 billion have been stolen by hackers from exploiting vulnerabilities on cross-chain bridges. The amount is enormous comparison to other security breaches, such as DeFi lending hacks ($718 million) and decentralized exchange exploits ($362 million) in that period. Bridge exploits account for ~50% of all DeFi exploits, totaling ~$2.5B in lost assets These hacks can typically be attributed to smart contract loopholes (e.g. Wormhole & Nomad) or compromised private keys (e.g. Ronin & Harmony).

Cross-chain bridges have been the target of more than a few hacks this year, but new data from blockchain analytics provider Elliptic alleges one has been used to launder over half a billion dollars in ill-gotten crypto assets. According to an Aug. 10 report, crypto bridge RenBridge has facilitated the laundering of at least $540 million in proceeds of crime since 2020 through a process known as chain hopping — converting one form of cryptocurrency into another and moving it across multiple blockchains. Elliptic said that decentralized cross-chain bridges provide “an unregulated alternative to exchanges for transferring value between blockchains.” Rogue states and hacker groups For the most part, cross-chain bridges or blockchain bridges are used for legitimate purposes, en...
