Resolv Labs’ stablecoin, USR, has lost its U.S. dollar peg following an exploit of the token’s contract that allowed attackers to mint millions of tokens.

 

The exploit, which occurred on March 22, 2026, resulted in the creation of 50 million unbacked USR tokens, prompting the team to temporarily pause the protocol’s functions to prevent “further malicious actions.”

 

 

According to YieldsandMore, which first reported the story, the attack began with a 100,000 USDC deposit by the attackers, ultimately causing USR to lose its dollar peg and fall to $0.01.

 

After minting the USR tokens, the attackers converted them into wrapped USR (wstUSR) to access deeper liquidity on decentralized exchanges (DEXs). This allowed them to offload large amounts of wstUSR more gradually, reducing the risk of an immediate price crash of USR.

 

The next phase of the attack involved dumping and selling wstUSR tokens across multiple platforms, including KyberSwap and Velora. Using this method, the attackers swapped wstUSR for USDt and USDC, which were then aggressively converted into Ether (ETH).

 

Although the attack was first made public by the crypto research and analysis group YieldsandMore, the Resolv team was only able to pause the protocol three hours later.

 

“It took ResolvLabs three hours to pause its protocol. Roughly one hour of that delay came from the gap between submitting the multisig transaction and collecting the four required signatures to execute it,” YieldsandMore wrote on X.

 

While 50 million tokens were initially minted by the attackers, blockchain security company PeckShield reported that an additional 30 million USR tokens were later minted, bringing the total to approximately 80 million.

 

 

Price Action of USR in the Aftermath of the Exploit

The minting and dumping of USR tokens triggered a severe depeg, sending its price from $1 to roughly $0.02 to $0.05 within minutes, a decline of about 95 to 97%.

 

Although it briefly rebounded to between $0.14 and $0.20, USR is currently trading at $0.2773, according to data from CoinMarketCap at the time of publication. 

 

The USR depeg ranks among the most severe in recent history, second only to the collapse of Terra's TerraUSD (UST) in 2022, which fell from $1 to $0.02 and lost 98% of its value. Iron Finance also had its IRON stablecoin lose its dollar peg, dropping from $1 to about $0.05.
