Radiant Capital Freezes Lending and Borrowing After $4.5M Flash Loan Attack
In a gripping turn of events, Radiant Capital, a leading cross-chain lending protocol, has momentarily frozen its lending and borrowing avenues on the Arbitrum network. This decision comes hot on the heels of a meticulously orchestrated exploit, draining a staggering $4.5 million (equivalent to 2337 ETH) from its recently inaugurated USDC Coin (USDC) markets.
Radiant’s tech team, working alongside cybersecurity experts, identified the breach as a flash loan attack. The issue stemmed from a subtle rounding discrepancy in the protocol’s code. Beosin, a leading blockchain security firm, highlighted how this rounding problem led to an unexpected precision error.
Exploiting this error, the attacker adjusted an index parameter. This tweak caused a sharp inflation and resulted in errors during deposit() and withdraw() operations. This flaw gave the attacker a brief yet significant opportunity to gain substantial profits.
Details of the Flash Loan Attack and Its Codebase Connection
PeckShield, an analytics firm, found a connection between this exploit and a vulnerability in the Compound/Aave codebase. Notably, the USDC market was targeted a mere six seconds after its launch. This revelation emphasizes the need for enhanced caution when introducing new markets.

A thorough investigation is underway, and operations will resume once completed. Radiant Capital, known for its cross-blockchain asset trading, is now closely observed by the crypto community.
