The project team commented on the flaw on its Twitter account on Wednesday (23).

According to the project’s website, Cashio is a Solana-based DeFi app that allows users to mint the stablecoin. Cashio Dollar (CASH), launched in November 2021.

At cashio, all deposits are guaranteed by interest-bearing liquidity provider tokens. For example, one can provide liquidity with stablecoins like USDT and USDC to mint CASH.

In this incident, the hacker found a vulnerability that allowed them to mint an infinite supply of CASH without having to provide sufficient collateral.

According to Solscan data, the hacker minted 2 billion CASH stablecoins. He then converted the tokens into other assets, notably other stablecoins. The conversion was done through the decentralized exchange Saber.

After that, the Saber platform reported that it had paused its CASH liquidity pools.
