As the cryptocurrency market continues to grow, so too does the need for robust security solutions. The recent concerns raised by SlowMist’s Cosine regarding Privy-based wallets highlight the ongoing risks that crypto users face.
The Growing Threat to Crypto Wallet Security
With hacks becoming more sophisticated, the importance of securing crypto wallets with mechanisms like two-factor authentication (2FA) has never been more urgent.
Cosine’s warning underscores the vulnerability of wallets that do not implement 2FA, stressing that assets could be stolen with just one click.
Crypto wallets have long been a target for hackers. Last year, the hack of WazirX’s wallet made headlines as attackers made off with millions in digital assets.
This breach raised alarm bells across the crypto industry, further exposing the security flaws that can occur when users fail to implement additional layers of protection.
Crypto wallets are an essential tool for users to store, manage, and transfer their digital assets. However, the rising number of attacks on these wallets highlights how essential it is to safeguard them.

Privy Wallets and the Importance of 2FA
SlowMist’s Cosine emphasized that enabling 2FA is vital for users with wallets built on the Privy platform. While Privy uses Shamir’s Secret Sharing (SSS) to split private keys into three shares—device, auth, and recovery—Cosine points out that the real plaintext private key is reconstructed in the target frontend.
This means that without 2FA, the wallet could be compromised easily, leading to a total loss of assets. In a document shared by SlowMist’s Cosine, Privy stated that it has implemented a sophisticated approach to key management.
The wallet creates a public-private key pair, which is then split into three shares: one stored on the user’s device, one encrypted and stored by Privy, and one that can either be managed by the user or stored within Privy’s key management system.
The system is designed to ensure that no single entity holds the full private key, offering an additional layer of security. However, Cosine’s warning suggests that without 2FA, hackers could bypass this multi-share system, gaining access to the assets with minimal effort.
Addressing the Issue of Crypto Wallet Security
The growing issue of wallet security calls for urgent action. Users are encouraged to take responsibility for securing their digital assets. By implementing 2FA and other security measures, such as biometric authentication or hardware wallets, crypto holders can add much-needed layers of protection.
