Midas emphasized that this is a standalone measure for mAPOLLO, and operations of other assets on the platform remain unaffected.

On March 23rd, USR, a stablecoin under Resolv, experienced a major security incident. Attackers exploited a private key leak to mint approximately $80 million in unbacked tokens, causing USR's price to collapse to $0.27, a decline exceeding 70%. Resolv has suspended smart contracts and burned 9 million anomalous tokens, with 71 million unbacked USR remaining in circulation. This incident reflects the fragility of stablecoins in terms of security and transparency, posing challenges to market confidence.

Resolv Labs announces the enablement of redemption functionality for pre-attack USR, scheduled to launch on March 23rd, with affected users required to contact RDAL. This incident stemmed from a third-party attack, with underlying assets remaining uncompromised. The protocol is currently tracking illegally minted USR and recommends users suspend related transactions.

The Fluid team has secured short-term loans covering 100% of non-performing debt to ensure user funds safety. ResolvLabs will handle USR positions prior to the security incident, and investors intend to increase FLUID holdings to strengthen protections. Smart contracts are functioning normally, market operations are stable, with potential interest rate fluctuations possible.

Gate News reported that on March 22, DeFi protocol Fluid released an announcement stating that it learned of the Resolv hacker incident. Fluid's automatic credit limit mechanism prevented excessive borrowing of funds, and the USR market has been suspended from trading with the situation under control. Fluid stated that if there are any bad debts remaining on the protocol, all user losses will be fully compensated. User funds and protocol security are Fluid's top priorities, and a comprehensive review is currently underway. A detailed post-mortem analysis report will be released after the investigation concludes.

Euler Labs confirmed on the X platform that it is aware of a security incident involving unauthorized minting of USR, which is under investigation. It has disabled RLP as collateral and suspended USDC distribution to isolate the risk. Further updates will be provided.

Aave founder Stani.eth stated that Aave has no risk exposure to Resolv's stablecoin USR, and collateral assets are secure. Resolv has begun an orderly exit and debt repayment, with no impact on Aave's liquidity providers or the protocol.
