The Solana Foundation patched a critical vulnerability in its Token-2022 standard in April, preventing potential token minting and fund withdrawal attacks. The flaw was fixed within two days with support from development teams and security firms. The bug affected the confidential transfers feature, causing a slight drop in token value. Critics questioned Solana’s decision to keep the issue quiet, while others defended it as a common practice for handling zero-day bugs. Industry veterans supported the covert fix approach, citing similar instances in Bitcoin and Ethereum. Solana co-founder Anatoly Yakovenko compared the validator coordination process to consensus-building mechanisms on Ethereum.
