anchored·3yruQw…sxZHSummary
Cashio was a Solana-based algorithmic stablecoin protocol that issued the CASH token, collateralized by Saber LP tokens. On March 23, 2022, an attacker exploited a critical missing validation flaw in the smart contract to mint approximately 2 billion CASH tokens backed by worthless fake collateral, draining roughly $52 million in real assets and permanently destroying the token's USD peg. The protocol was unaudited, never compensated victims in full, and its pseudonymous creator later admitted the code was rushed and insecure.
