The amount of money lost in hacks decentralized financing (DeFi) projects more than doubled to $ 1.3 billion in 2021, with centralization being the most common vulnerability, Certik said in its first state of DeFi security research report.

For example, some projects were gutted when hackers obtained private keys that gave them full control over smart contracts. This would probably have been avoided by using multi-signature wallets or DAO instead of one or a set of private keys.

It now generates more than 64 times the revenue of Bitcoin and 4 times the number of daily transactions. But Ethereum has also suffered from its success, as high transaction fees sent users to other platforms.
