Top DeFi Exploits in 2026
KelpDAO ranked first with a loss of $292 million. The attacker targeted the rsETH bridge and drained the funds.
The same material linked the KelpDAO rsETH exploit to the $5 billion Aave liquidity crunch now being watched. It also said bridges and oracles continue to drive losses. The content further stated that 2026 is on pace to cross $3 billion in losses by year-end.
Drift ranked second with a loss of $285 million. The attacker used oracle manipulation and included a fake token. That exploit placed Drift just behind KelpDAO in the 2026 ranking.
Step Finance held third place after losing nearly $40 million. The attacker compromised the platform’s private keys. That incident added to the focus on key-related security failures in DeFi this year.
Truebit ranked fourth with a loss of about $26.4 million. The reported cause was a smart contract bug. That made it the largest contract-related exploit in the top section of the list.
Smaller DeFi Exploits Add to 2026 Losses
Resolv took fifth place with a loss of $25 million. The exploiter compromised the platform’s AWS KMS key.
Rhea Finance stood in sixth place after losing $18.4 million. The exploit involved oracle manipulation and a fake token.
Grinex ranked seventh with a loss of $13.7 million. The reported cause was an exit scam or insider drain. That case differed from the bridge, oracle, and key exploits seen elsewhere on the list.
SwapNet placed eighth after losing $13.4 million. The attacker used approval abuse to extract funds. YieldBlox followed with a loss of $10.2 million tied to collateral or oracle manipulation.
Saga closed the top ten with a loss of $7 million. The reported cause was a bridge exploit. It recorded the smallest loss among the listed DeFi incidents.
The figures show that the biggest damage came from a small group of platforms. KelpDAO and Drift alone accounted for most of the reported losses in the provided breakdown. Their combined total reached $577 million.
