Solana is launching privacy tools that can hide token balances and transfer information, while projects like Anoncoin are offering developers up to $10,000 in rewards to create private token issuance tools. These features, based on zero-knowledge cryptography technology, aim to provide optional privacy protection and foster innovation, but they also raise concerns among retail investors. These new features could conceal key information such as token supply and holder distribution, making due diligence more difficult and potentially increasing the risk of hidden malicious activities like "exit scams" in rapidly evolving sectors like meme coins.
