Radix blockchain halted for 10 days following $1.3 million exploit

A code refactor in the Radix Engine introduced a vulnerability that went undetected for over three years, allowing an attacker to drain approximately $1.3 million in assets on August 31. The attacker moved funds including USDC, USDT, ETH, wrapped Bitcoin, SOL, and BNB across multiple chains using Hyperlane. To prevent further exploitation while a fix was developed, network validators took the blockchain offline by halting consensus. The flaw had previously passed an independent security audit by Zellic in 2024.
