#What is SolanAuth?

SolanAuth is a free, open-source demo application showcasing responsive Solana wallet authentication and an account modal, integrating NextAuth.js with shadcn/ui components. Its primary goal is to provide developers with a practical example of Solana wallet-based sign-in for decentralized applications (dApps), targeting React developers building Web3 apps on the Solana blockchain, such as NFT marketplaces or DeFi platforms. Built with Next.js, NextAuth.js, Solana Wallet Adapter, shadcn/ui, Tailwind CSS, and TypeScript, it offers a user-friendly authentication flow with wallet connection (e.g., Phantom, Solflare) and a styled account modal. The project, bootstrapped from the next-auth-example repository and adapted from SIWE (Sign-In with Ethereum), supports in-memory auth state persistence, allowing users to stay signed in without constant wallet reconnection. For shadcn/ui enthusiasts, SolanAuth is a perfect fit, delivering accessible, modern UI components for Web3 authentication, hosted on Vercel.
