Bridge Attacks Continue to Threaten DeFi Industry Security

The decentralized finance (DeFi) industry has faced numerous challenges in terms of security, with hackers stealing over $2.5 billion through vulnerabilities on cross-chain bridges between 2020 and 2022, according to Token Terminal data.

These attacks are particularly concerning due to the inherent exposure of bridges, which connect different blockchains and aim to address the lack of standards between protocols. As Theo Gauthier, CEO of Toposware, explains, any breach or bug within one of the two bridged chains makes the overall bridge vulnerable, regardless of its own level of security. Despite these challenges, the DeFi industry is expected to continue to grow and evolve, with players working to build trust within their respective ecosystems and address ongoing security concerns.

Zero-Knowledge Proofs Offer Solutions for Interoperability and Security in Cryptocurrency Industry

One of the major technologies emerging as a solution for interoperability and security in the cryptocurrency industry is zero-knowledge proofs (ZKPs). These allow data to be verified and proven as accurate without revealing further information, in contrast to typical interoperability solutions that require networks to disclose their states. KPIs can also be used to create a ZK-powered Ethereum Virtual Machine (EVM), enabling developers to launch scalable and completely private Ethereum-compatible smart contracts, according to Mudit Gupta, Chief Information Security Officer at Polygon. The adoption of ZKPs and other technologies that prioritize privacy and security may help to enhance the end-user experience and promote broader adoption of cryptocurrency.

Strategies for Improving Security in DeFi Industry

To address the issue of bridge attacks and improve overall security in the DeFi industry, experts recommend a range of strategies. These include auditing and real-time monitoring standards for bridges' smart contracts, which should be thoroughly reviewed by multiple third parties before being released and updated as needed. Additionally, machine learning technology can be used to flag potentially suspicious patterns of activity and detect attacks before they occur through advanced security monitoring.


Combining security software solutions with blockchain protocols may make the entire space more secure for users and investors. While smart contracts for Bitcoin are in the works as an alternative solution, DeFi players will need to continue working to build trust within their respective ecosystems and address ongoing security concerns.
