According to the website DeFiPrime, there are currently over 200 DeFi projects on the Ethereum network. Yet while Ethereum appears to be the most suitable platform for DeFi projects, the network’s vulnerabilities have played a large role in hacks and fraudulent activities.

Smart contract transactions on Ethereum require security

Specifically speaking, the smart contracts that power Ethereum are known for being fraught with security issues, which, in turn, have greatly impacted DeFi projects. In addition, smart contracts being applied to DeFi projects worth billions of dollars are often not audited beforehand.

Tom Lindeman, a previous veteran researcher at Microsoft and the former managing director of the Ethereum Trust Alliance — a group of blockchain companies working on a security system for smart contracts — told Cointelegraph that there is currently no good ways to identify whether a smart contract is secure before initiating a transaction:

“The DeFi space is worth billions of dollars now, but so many of those smart contracts being used a...
