Web3 ログイン SDK

Web3Auth is a non-custodial authentication infrastructure designed to simplify user onboarding and login for Web3 wallets and decentralized applications. It enables developers to integrate seamless social logins such as Google, Twitter (X), Discord, Email, and Passkeys, combined with advanced cryptographic security through Multi-Party Computation (MPC). This approach allows users to access Web3 applications without managing seed phrases, improving user experience and conversion rates. Web3Auth supports a wide range of blockchains including EVM-compatible chains, Solana, Bitcoin, SUI, Aptos, Cardano, and others, making it blockchain agnostic and suitable for multi-chain projects.

The platform offers two main SDK approaches: Plug and Play SDKs for quick integration with customizable UI components, and Core Kit SDKs for headless, fully customizable implementations. These SDKs cover web, mobile (iOS, Android, React Native, Flutter), and gaming platforms (Unity, Unreal), enabling developers to embed Web3Auth into diverse environments with minimal Web3 expertise. Additional features include native account abstraction for smart accounts, multi-factor authentication, server-side verification, wallet pre-generation, and wallet aggregation with third-party connectors.

Web3Auth differentiates itself by combining enterprise-grade security with user-friendly onboarding, reducing support tickets by 80% through key recoverability and non-custodial 2FA. It also offers post-authentication wallet services such as fiat on-ramp aggregation, NFT minting and checkout, and a whitelabel UI for branding. Trusted by major Web2 and Web3 players, Web3Auth has onboarded over 15 million users globally and supports rapid wallet creation in under a second. Developers can get started quickly with comprehensive documentation, example projects, and a demo app, making it a practical choice for teams aiming to scale user acquisition and retention in Web3 applications.
