Today, March 22, 2026, the DeFi sector was shaken by news of a critical vulnerability in the Resolv Labs protocol. The USR stablecoin lost its peg to the US dollar due to a large-scale exploitation of the smart contract.
🔍 What happened?
Attack Mechanics: The attacker used only ~$100,000 USDC as an initial deposit to mint around 80 million unsecured USR tokens due to an authorization error in the exchange (requestSwap to completeSwap).
Price implications: The hacker began mass converting USR into USDC, USDT, and $ETH through liquidity pools (notably Curve Finance). This led to an immediate price collapse: at one point, the rate dropped to $0.025. The token is currently trading around $0.04.
Losses: Analysts estimate the direct losses of the protocol at least $25 million.
🛠 Team Reaction
The Resolv Labs team promptly suspended all protocol functions to prevent further manipulations. An investigation is currently underway in collaboration with cybersecurity experts (notably PeckShield) to recover funds and eliminate vulnerabilities.
💡 Why is this important?
This incident once again highlights the risks of "algorithmic" and delta-neutral stablecoins. Even with low hacking intensity in February, March shows that one mistake in the code can destroy trust and the project's capitalization in a matter of minutes.
Be cautious with assets that demonstrate abnormal profitability! 🛡
