Apart from that, when it comes to the loss of value in DeFi exploits during 2026, Resolv stands in the 3rd position. The platform lost a total of more than $25M. Specifically, a minting vulnerability paved the way for this exploit. In addition to this, SwapNet became the 4th of DeFi entities losing massive capital amounts. So, it lost a cumulative $13.4M due to an arbitrary call.
The next name on the list is YieldBlox, which is the 5th among this year’s leading DeFi exploits up till now.
