The Bulk

Phantom is addressing the problematic state of user authentication by introducing a feature called Sign In With Solana (SIWS). This tool will allow apps to authenticate users quickly and securely using only a Solana address.

SIWS comes with a simplified one-click sign-in method, improving the overall experience for both users and developers. Instead of encountering jarring signature requests or confusing authentication flows, users can sign in smoothly with just a single click.

Additionally, this new method removes the burden of message construction from app developers, handing it over to Phantom's wallet. The standardized message construction creates a unified authentication process, eliminating the fragmentation that often causes a poor user experience.

SIWS is fully compliant with the Solana Wallet Standard, making it possible to be easily integrated into other wallets within the Solana ecosystem.
