If you've been building with Web3Auth, you already know the product. Now it has a new home, a new name, and a significant upgrade.
MetaMask Embedded Wallets is live and can be managed through the MetaMask Developer Dashboard. The Web3Auth name will be going away, as the wallet infrastructure used by McDonald's, eBay, NBCUniversal, and hundreds of other teams is now fully integrated into the MetaMask developer ecosystem.
This post walks through what Embedded Wallets is, what's new, and how to get a working integration running in minutes.
What is MetaMask Embedded Wallets?
MetaMask Embedded Wallets lets you embed self-custodial wallet infrastructure directly inside your app, game, or platform. Your users sign in with familiar methods like email, SMS, social login, or an existing wallet. A new wallet is created and managed behind the scenes. No browser extension required, which means no secret recovery phrase or onboarding friction.
With tens of millions of monthly active users, MetaMask is the most recognized name in crypto and onchain finance. When you embed our wallet infrastructure, your users onboard with confidence because they already trust the name.
What's new
For teams already building with Web3Auth, today’s version of MetaMask Embedded Wallets consolidates the product under the MetaMask developer platform and introduces several meaningful changes:
A unified developer experience: The new MetaMask Developer Dashboard is the single control plane for your Embedded Wallets integration: Manage API keys, configure authentication flows, control project settings, and monitor analytics, all from one place.
Updated SDK and documentation: All SDK references, quick start guides, and tutorials now live at docs.metamask.io/embedded-wallets. The old web3auth.io/docs URLs are deprecated. Framework-specific guides are available for React, Vue, Angular, React Native, Flutter, iOS, Android, Unity, and Unreal.
Native smart account support: It includes built-in smart wallets powered by the MetaMask Smart Account Kit. Enable account abstraction, gas sponsorship, batch transactions, and configurable permissions directly through the dashboard, no additional infrastructure required.
New access controls: Gate access by email, domain, or wallet addresses. Run closed betas, ship token-gated experiences, or block bad actors with granular policies configured from the dashboard.
Frictionless onboarding customized for your brand
The core value proposition hasn't changed: get users into your app without making them think about wallets.
Your users sign in with email, SMS, social accounts (Google, Apple, Twitter, Discord, and any OAuth2 provider), or an existing web3 wallet. The entire login experience is whitelabeled to your brand, your logo, your colors, your name. Multiple wallets can be linked to a single account with unified user management.
This works across EVM chains, Solana, Bitcoin, and more. Bring your existing authentication system if you have one: Embedded Wallets supports custom OAuth2 providers and existing identity flows, so your users don't need to learn anything new.
Every essential wallet feature in one SDK
Embedded Wallets ships with the infrastructure most teams end up building themselves:
Custom authentication: Bring your existing users to web3 without an additional learning curve. Support for OAuth2, passwordless, and social login out of the box.
Native account abstraction: Activate smart wallets with gas sponsorship and batch transactions. Your users never need to hold native tokens to transact.
Unified identity (or Account Linking): Let users link social logins with external wallets and move across wallets and devices with a single identity for a seamless experience.
Access control: Gate by email, domain, or wallet; useful for closed betas, loyalty programs, and token-gated features.
Funding: One-click fiat-to-crypto via debit cards, Apple Pay, Google Pay, and local payment rails, plus transfers from any external wallet.
x402 payments: Native support for HTTP-native, pay-per-request, and machine-to-machine payment flows.
Granular user management: Know your users: view their identities, auth methods, and activity in one place, right from the dashboard.
Security built for enterprise, simplicity designed for developers
Embedded Wallets use two-layer threshold cryptography, including on-device Shamir's Secret Sharing and a backend distributed key generation for non-custodial key management. A user's key is split into multiple shares distributed across their device, the Embedded Wallets network, and a recovery factor. No single party ever holds the complete key.
The infrastructure is SOC 2 Type II certified, GDPR and CCPA compliant, and backed by a 99.99% uptime SLA. Routine security audits are conducted by Kudelski Security, Cure53, Uniquely and many more.
This is the same architecture trusted by Fortune 500 companies running production workloads at scale.
Chain-agnostic infrastructure
Embedded Wallets are blockchain-agnostic with native support for EVM and Solana chains, plus dedicated integration guides for Bitcoin and other networks. The full list includes Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Chain, Solana, and dozens more.
The MetaMask Developer Dashboard
The new MetaMask Developer Dashboard is where you configure and manage your Embedded Wallets integration. It replaces the previous Web3Auth dashboard as the primary interface for:
Creating and managing projects and API keys
Configuring login methods and authentication flows
Branding the wallet UI with your logo, colors, and copy
Enabling smart accounts and account abstraction
Monitoring Monthly Active Wallets and usage analytics
Managing team members and access
The dashboard is live now. If you have an existing Web3Auth account, your configuration carries over.
