Introducing ‘Standard on Security’ Is Key to Thwarting DeFi Hacks: OpenZepplin Security Lead

To stop hacks in decentralized finance (DeFi), the crypto business must decide to universally agreed-upon safety requirements, the safety lead for good contract auditing agency OpenZeppelin advised Decrypt.

Talking at this yr’s EthCC occasion, OpenZeppelin safety options architect Michael Lewellen emphasised the significance of setting a “normal on safety” with a “broad settlement” throughout the auditing companies and builders within the house to guard customers.

Presently, protocols depend on audit experiences from blockchain safety companies. Nonetheless, there have been situations up to now the place an auditor didn’t discover bugs, however the contracts had been hacked regardless.

For example, cross-chain interoperability blockchain Thorchain repeatedly went again on its safety audits after a number of hacking makes an attempt.

Lewellen advised Decrypt that it “appears a bit of loopy to me” that crypto companies take auditors “at their phrase,” including that on many events, builders and customers additionally ignore the vulnerabilities cited in auditors’ experiences.

Currently, many tasks equivalent to BitDAO–rebranded as Mantle Community–and Celo have relaunched as Layer-2 networks on Ethereum. Lewellen mentioned that whereas they’ll proceed with separate approaches, it is necessary to stick to requirements on necessary parts like how they work together with customers, one another, and Ethereum—citing Optimism’s OP stack for instance.

Requirements in the way in which cross-chain purposes work together with one another may assist in stopping bridge hacks, which have been rampant within the house, Lewellen mentioned.

The entire worth stolen from DeFi protocols within the three years because the DeFi summer season of 2020 has reached $6.74 billion, per DeFiLlama knowledge. Cross-chain bridges account for almost 40% of the overall quantity, with the remaining coming from DeFi.

Primarily based on his expertise at an auditing agency, Lewellen mentioned, generally tasks “aren’t prepared to pay for the time to do broad, complete safety.” This results in vulnerability and undue stress on auditing groups.

Lewellen advised Decrypt that “requirements assist” in constructing belief amongst customers, auditors, and builders as a result of it expands past one entity’s opinion. ”It is a broad business normal,” he mentioned, noting that requirements act as a proxy certification of the protocol’s security.
