Decentralized Finance (DeFi) has rapidly gained popularity in recent years, offering users financial services without intermediaries. However, the rise of DeFi has also attracted malicious actors, resulting in numerous high-profile hacks and vulnerabilities. In this blog post, we will explore some of the notable DeFi hacks that have occurred, the lessons learned from each incident, and the ongoing challenges faced by the industry.


$800k Hack – July 2, 2021

The ChainSwap hack exposed a smart contract bug, causing users to lose funds. ChainSwap swiftly responded by shutting down all nodes and deploying a fix within 30 minutes, showcasing the importance of quick response times and effective communication during a crisis.

$4.4M Hack – July 10, 2021

ChainSwap faced another vulnerability just days after the initial incident, resulting in significant financial losses. This incident highlighted the need for continuous security audits and thorough testing of smart contracts to prevent repeat vulnerabilities.


$7.9M Hack – July 10, 2021

Compromised MPC keys due to repeated k-values led to the Multichain hack. This incident underscored the importance of secure key management and the need to regularly review and update cryptographic protocols to prevent key-related vulnerabilities.

$3M Hack – January 17, 2022

The Multichain hack exposed vulnerabilities in approvals, resulting in the draining of funds. Whitehat hackers played a significant role in recovering a portion of the stolen funds. The incident showcased the value of ethical hackers and the potential for bug bounties as an incentive for vulnerability discovery.
