What’s new? Experts from cybersecurity company PeckShield have reached out to the team of multi-chain liquid staking platform Meta Pool with information about the discovered vulnerability. On their X page, the experts warned that a critical bug in the platform’s staking contract allows for the free issuance of mpETH coins, which are made available to users after the original ETH is blocked in staking.

What else is known? In particular, PeckShield detected a suspicious transaction in which an unknown user minted more than 9700 mpETH for free, valued at around $27 million. At the same time, the low liquidity of the asset limited the profit from the transaction to only 10 ETH.

Meta Pool later confirmed an attack on the mpETH contract on the Ethereum network, which allowed unauthorized minting of the asset via the mint function.

Thanks to early detection, the team promptly halted the contract and prevented further damage.

The project’s team has already started studying the potential impact of the exploit on various decentralized crypto exchanges (DEXs) and cross-chain protocols. It is also investigating the attack vector, working on fixing the vulnerability, and preparing a further action plan for the community.

Run by a decentralized autonomous organization (DAO), the Meta Pool platform allows NEAR, ETH, SOL, AURORA, and Q tokens to be placed into staking. It provides users with staking rewards and liquid staking tokens that can be used in DeFi protocols to generate additional yields while the original coins are blocked.

The project successfully passed an audit by IS firm BlockSec in February 2022.

Earlier this month, leading centralized crypto exchange (CEX) MEXC launched a $100 million fund to compensate customers in the event of a hack or outage.
