- Resolv Labs lost control of its USR stablecoin after a private key exploit.
- An attacker minted 80 million unbacked tokens with minimal collateral.
- The incident spread losses across multiple DeFi platforms, including Morpho vaults.
Resolv Labs faced a major security breach that disrupted its stablecoin system. The project confirmed that an attacker exploited its minting process and created a large supply of unbacked tokens. The issue surfaced on Sunday and quickly spread concern across decentralised finance markets.
The attacker minted 80 million USR tokens while providing less than 200,000 dollars in collateral. This action broke the core structure of the stablecoin. USR relies on balanced trading strategies to maintain its value near one dollar.
The sudden increase in supply removed that balance and triggered a sharp decline. Market data showed heavy selling pressure. USR dropped below 0.4 dollars and briefly touched 0.02 dollars. Many holders rushed to exit positions.
Resolv Labs Faces Heavy Selling Pressure and Rising Losses
The increased selling further aggravated the losses. The protocol’s response was to disable minting and redeeming. The intention was to limit further damage to the protocol. However, by then, losses had already spread throughout the market.
The investigation into the matter revealed that the attacker had access to the project’s private keys. The private keys provided access to internal operations that can be controlled. The attacker was able to mint more coins because they had access to this part of the system. The private keys are part of the project’s key management system in cloud infrastructure.
The keys are used to manage operations in a blockchain system. Whoever has access to these keys can perform operations without any limits. Security experts identified that the system had no restrictions in its minting contract. The system had no verification process to ensure that no more coins are minted.
DeFi platforms face losses after the USR collapse spreads risk
After doing so, they transferred funds among different assets. They exchanged USR into its staked forms and then into a stable token with a dollar peg. They then used these funds to buy Ether. Data from the blockchain estimated total gains to around 23 million dollars.
The impact was not limited to Resolv Labs alone. Many decentralised platforms that had integrated USR into their systems also suffered losses. Morpho is a lending platform with a curator system. It presents an instance where risks can spread throughout systems that are interconnected.
Morpho is a lending system that allows third-party managers to create customised lending pools. These managers are called “curators.” They are responsible for selecting assets and defining risk settings. Some of these curators had included USR in their lending pools to earn interest. However, they suffered losses due to USR’s collapse. Some systems continued to provide liquidity even after the exploitation.
This caused further losses. It was reported that 15 vaults with considerable liquidity were affected. However, they took prompt action to manage risks and limit further losses. This demonstrates the need to enhance security and manage risks in decentralised finance systems.
