Web3Auth

Web3Auth is a non-custodial key management infrastructure platform founded in 2019 and now operating as a Consensys formation. The company provides developer SDKs and APIs that enable Web3 applications and wallets to offer familiar, seed-phrase-free onboarding experiences powered by Multi-Party Computation (MPC) and Account Abstraction (AA).

With a mission to make digital ownership and identity human-centric and accessible to everyone, Web3Auth has grown to serve nearly 50 million end users across more than 8,200 decentralized applications (dApps) globally. The platform is trusted by leading Web2 brands and top Web3 applications including Coinbase, Binance, Ronin Wallet, Animoca Brands (Mocaverse), and chess.com.

Core Products/Services

Web3Auth's platform is structured around two core authentication SDK families and a post-authentication wallet services layer:

• Plug N Play SDK: A pre-built, customisable login UI that enables developers to onboard users with social logins (Google, X, Email, Passkey) in minutes, with support for whitelabelling.
• MPC Core Kit SDK: Headless SDKs (Web, iOS, Android, Node.js) that give developers full control over the UX while retaining enterprise-grade MPC key security. Supports tKey JS, single-factor auth, and mobile-native integrations.
• Account Abstraction: Native ERC-4337 smart account creation and management, supporting gas sponsorship, batch transactions, session keys, and EIP-7702/ERC-7579 standards. Compatible with leading AA providers.
• Wallet Services: Post-authentication tooling including a pre-built Wallet UI, Fiat On-ramp Aggregator (100+ local payment methods, up to 70% lower fees), NFT Checkout, and wallet pre-generation for loyalty and airdrop programmes.
• Multi-Party Computation (MPC) Infrastructure: Enterprise-grade distributed key management using MPC-DKLS19, enabling transaction signing in under 1.2 seconds without seed phrases. Blockchain-agnostic, supporting ECDSA, EdDSA, BLS and more.

Key Strengths

• Non-custodial by design: Users retain full control of their private keys; Web3Auth never holds keys on behalf of users.
• 2.3x user conversion improvement: Replacing seed-phrase flows with social logins demonstrably increases dApp conversion rates from ~25% to ~60%.
• Blockchain universality: Supports Ethereum/EVM, Solana, Bitcoin, SUI, Aptos, Cardano, dYdX, THORChain, TON, NEAR, Starknet, and more.
• Security and compliance: SOC2, CCPA, CPRA, and GDPR compliant; codebase is regularly audited internally and externally.
• Fast, scalable infrastructure: Geo-distributed, horizontally scaled nodes deliver MPC login and signing in under 1.2 seconds globally.
• Developer-first: Comprehensive documentation, guides, community forum, and a free tier covering the first 1,000 Monthly Active Wallets (MAWs).

Notable Clients/Projects

• Ronin Wallet (Sky Mavis): Social login integration enabling seamless onboarding for gaming wallet users.
• Mocaverse (Animoca Brands): 1.5 million on-chain mints in 6 months using Web3Auth's AA wallet with gasless capabilities and fiat-to-crypto.
• FanTV: Integrated Web3Auth without requiring technical assistance from the team, citing clear documentation.
• chess.com: Enabled existing chess.com identities to seamlessly mint and create NFTs.

Why Choose Web3Auth

Web3Auth eliminates the primary UX barrier to Web3 adoption — the seed phrase — without sacrificing decentralisation or user ownership. Developers can integrate in as little as 15 minutes using the Plug N Play SDK, or build fully bespoke experiences with the headless Core Kit. The platform's MPC architecture ensures that even if Web3Auth's servers are compromised, user keys remain secure. As a Consensys formation, Web3Auth benefits from deep integration with MetaMask and the broader Ethereum ecosystem, positioning it at the centre of the next generation of Web3 onboarding infrastructure.
