Cascade Protocol
Summary
Cascade Protocol is a Polychain Capital and Variant-backed perpetual trading platform (self-described as a neo-brokerage) that suffered a $1.34 million USDC exploit of its Cascade Liquidity Strategy (CLS) vault on July 16, 2026. The affected funds came from locked First Wave depositor accounts that users were unable to withdraw prior to the attack, compounding losses. Multiple on-chain analysts had issued public warnings about the protocol's inactivity and declining vault liquidity in the weeks preceding the exploit, but no timely remediation occurred.
