DEX protocol KyberSwap appears to lose $47 million in possible exploit

Quick Take

  • Unexpected wallet movements suggest KyberSwap has suffered a $47 million exploit.
  • The funds seem to have been drained from liquidity providers.

Decentralized exchange protocol KyberSwap appears to have suffered a $47 million exploit, according to on-chain data. The funds were from its Elastic Pools liquidity solution.

Funds have been unexpectedly moved from wallets associated with the protocol into a single wallet, as first pointed out by a user known as Spreek on X.

The funds include $20.7 million Arbitrum, $15 million on Optimism, $7 million on Ethereum, $3 million on Polygon and $2 million on Base.

A large portion of the funds are denominated in various forms of ether, such as wrapped tokens and liquid staking tokens, as well as other tokens including arbitrum (ARB) and various stablecoins.

KyberSwap warned in a post on X that KyberSwap Elastic experienced a “security incident” and advised all users to promptly withdraw their funds. “Our team is diligently investigating the situation, and we commit to keeping you informed with regular updates.”

A message in a transaction that appears to have been sent by the attacker said, “Dear Kyberswap Developers, Employees, DAO members and LPs, Negotiations will start in a few hours when I am fully rested. Thank you.”

KyberSwap Elastic lets liquidity providers choose their preferred price ranges while seeing their yields automatically compound.

"I looked into the [transaction] and dont think it's an approval issue with kyber aggregator, seems like hacker is just draining the kyber [liquidity provider] pools," noted 0xngmi, a pseudonymous employee at crypto data site DefiLlama, on X. He added that the total value locked in the protocol is $72 million. This doesn't appear to have been affected.
