Resolv’s USR stablecoin depegged following an apparent smart contract exploit on Sunday that allowed an attacker to mint 80 million USR tokens and dump them across decentralized exchanges, as noted by onchain analysts Ai Yi (@ai_9684xtpa) and PeckShield.
.@ResolvLabs It seems multiple large amounts of $USR have been minted. Stay alert!

USR was rapidly destabilized, dropping to as low as $0.2 before recovering to around $0.8, according to CoinGecko.
In a statement, Resolv Labs, the core developer of the Resolv Protocol, said they had temporarily halted operations following the exploit. The team is investigating and taking steps to contain the situation.
Resolv has experienced an exploit that allowed the attackers to mint 50mn of unbacked USR.
The team has currently paused all the protocol functions to prevent further malicious actions and is actively working on recovery.

USR is a 1:1 dollar-pegged stablecoin built by Resolv to operate entirely on-chain. Rather than holding fiat reserves, it maintains its value using over-collateralized crypto assets such as ETH, staked Ethereum, and Bitcoin.
RESOLV, the protocol’s native token used for governance and value capture, dropped 6% to $0.054 on the news.
