Skip to main contentMoonKey provides authentication and wallet infrastructure that empowers developers to build seamless blockchain-powered applications. Whether you’re building for web3-native users or complete newcomers to crypto, MoonKey’s SDK helps you implement secure authentication, wallet management, and transaction signing in just a few lines of code.
What you can build with MoonKey
Seamless authentication flows — Create frictionless login experiences using multiple authentication methods including OAuth providers (Google, Apple, Discord, GitHub, Microsoft), magic links, email/SMS OTPs, passkeys (WebAuthn), TOTP-based MFA, and Web3 wallet signatures. Users can authenticate however they prefer, while you maintain a unified user identity across all methods.
Self-custodial wallet solutions — Generate and manage embedded wallets for your users without compromising on security. Whether users need a single wallet or multiple wallets across different blockchains, MoonKey handles the complexity of key management while keeping users in full control of their assets.
What makes MoonKey different
Security-first architecture
User security isn’t negotiable. Our infrastructure leverages distributed key sharding technology, meaning private keys are never stored in a single location—not even we can access them. Keys are only reconstructed within secure execution environments when transactions need to be signed.
Developer-friendly integration
We designed MoonKey to fit into your existing workflow. Our React SDK provides ready-to-use authentication components that work out of the box, while our REST API gives you complete control when you need custom implementations. Start with our pre-built UI components, then customize or replace them as your product evolves.
Built for scale
From authentication to wallet management, every component is designed to handle production-scale applications. Session management, device fingerprinting for fraud prevention, recovery mechanisms, and comprehensive user management APIs ensure your application remains reliable as you grow.
True multi-chain support
Native compatibility with Ethereum, Solana, and all EVM/SVM-compatible chains means you’re not locked into a single ecosystem. Deploy wallets and manage assets across any blockchain your application needs—today or in the future.
Whether you’re building a DeFi platform, an NFT marketplace, a gaming application, or any product that touches blockchain technology, MoonKey provides the authentication and wallet infrastructure you need to focus on what makes your product unique.
