CUT token holders could use their tokens to participate in yield farming activities, stake them for rewards, or engage with the platform’s gaming features, thereby increasing the demand and potential value of the token.
Overview of the DeFi landscape at the time of the hack
At the dawn of 2021, yield farming and liquidity pools had gained significant popularity and growth within the DeFi community. The concept of supplying liquidity to earn passive income through fees and rewards had attracted thousands of new investors to the decentralized finance space. The total value locked (TVL) in DeFi protocols skyrocketed, reaching new heights and breaking records every month.
Popularity and growth of yield farming and liquididity pools
As users continued to flock to DeFi projects, the demand for stablecoins like DAI and USDC increased significantly. These stablecoins were used as collateral for lending and borrowing activities, providing liquidity to various decentralized exchanges (DEXs) and earning fees in return. The popularity of yield farming led to the emergence of various DeFi projects, each offering unique rewards, incentives, and opportunities for investors.
Introduction to the hacker and their motivations
Amidst this thriving DeFi ecosystem, an anonymous hacker with the alias Mr. White Hat emerged. Mr. White Hat was a well-known figure in the Ethereum community, known for his ethics and white-hat hacking skills. He had previously identified vulnerabilities in other smart contracts and reported them to their respective development teams.
