DeFi security: How trustless bridges can help protect users By Cointelegraph

Blockchain bridges allow decentralized finance (DeFi) users to use the same tokens across multiple blockchains. For example, a trader can use (USDC) on the or blockchains to interact with the decentralized applications (DApps) on those networks.

While these protocols may be convenient for DeFi users, they are at risk of exploitation by malicious actors. For example, in the past year, the Wormhole bridge — a popular cross-chain crypto bridge between Solana, Ethereum, and others — was hacked, with attackers stealing over $321 million worth of wrapped Ethereum (wETH), the largest hack in DeFi history at the time.
