Web3 and decentralized applications on innovative networks like Mantle Network offer immense promise. From next-generation gaming to open financial systems, the potential is clear. Yet despite these possibilities, one persistent barrier continues to block mainstream adoption: complexity.

The entry point to Web3 has long been a confusing maze of browser extensions, app downloads, and the dreaded "seed phrase"—a 12 or 24-word password that, if lost, means your assets disappear forever. This isn't merely a hurdle; it's why, according to some analyses, around 65% of new users abandon platforms after their first dApp interaction. For average users, this complexity simply kills interest.

Mantle Network, in partnership with Para, is introducing the Mantle Passport, which is the MPC (Distributed MPC) wallet to eliminate these complexities while delivering a self-custodial, censorship-resistant universal wallet for dApps across the Mantle ecosystem.

How Distributed Mantle Passport Works

Mantle Passport is powered by Para. Para’s SDKs leverage Distributed MPC which eliminates the single point of failure present in traditional EOAs.

Here's how it works:

1. Key Splitting: Instead of creating a single private key, MPC divides the key into multiple pieces called "shares."
2. Distribution: These shares are distributed across independent parties. A typical "2-of-2" model includes:

• Share 1: Stored on the user's device (phone or computer).
• Share 2: Held by the wallet service provider (like Para).

3. Recovery: A recovery secret, typically linked to a user's social login (Google or Apple) and securely stored. https://docs.getpara.com/v2/concepts/recovery
4. Signing Transactions: To approve a transaction, a threshold of (2 out of 2) signature must cryptographically "sign" it. The critical feature is that the shares never combine to reconstruct the full private key—instead, they interact through a secure protocol to generate the signature.

The system is built on a distributed Multi-Party Computation (MPC) framework that uses distributed key generation (DKG) and signing. This approach ensures that user keys are never stored in a single vulnerable location. Neither applications nor Mantle/Para itself can access users' private keys, creating a robust foundation for secure, non-custodial wallet management. Combing the MPC and DKG is the solid foundation of censorship resistance.

Universal Embedded Wallet for Mantle ecosystem

1. One-click login across favorite apps - users can instantly access all their preferred applications and utilize the same wallet and liquidity they initially established when they first connected to an app.
2. dApps can launch on Mantle to a user base of funded wallets. So instead of starting from 0 and bootstrapping an audience, they can launch to an audience of retained, funded wallets

Summary

Universal Embedded Wallets offer the best of both worlds compared to traditional wallet options. They provide the same unified liquidity and portable reputation across apps as third-party wallets, while matching the smooth user experience and browser extension-free approach of traditional embedded wallets. They also excel with unique advantages including recoverable key management, granular per-app permissions, distributed key generation, and censorship resistance - creating a superior solution for the Mantle ecosystem.
