Overview

Multi-Party Computation (MPC) represents a fundamental shift in how we approach wallet security and user experience. By distributing cryptographic operations across multiple parties, MPC eliminates single points of failure while maintaining the flexibility and usability that modern applications require.

Security Benefits

No Single Point of Failure

Private keys never exist in complete form within Dynamic’s MPC system. Even during signing operations, the complete private key is never reconstructed, significantly reducing the risk of theft or compromise. This architectural approach removes the vulnerability that has plagued traditional single-key wallets.

Distributed Trust

Multiple parties must collaborate for operations to succeed. This means that no single entity—whether it’s the user, Dynamic, or any other participant—can unilaterally control the wallet. The system requires cooperation to function, creating a robust security model.

Compromise Resistance

Individual party compromise doesn’t break the overall security of the system. If one party’s share is compromised, the attacker still cannot access the wallet or perform unauthorized operations. This resilience is crucial for maintaining security in real-world scenarios where individual components may be vulnerable.

Auditable Operations

All operations can be cryptographically verified, providing transparency and accountability. Every signing operation leaves a verifiable trail that can be audited without compromising the underlying security model.

User Experience Benefits

Familiar Authentication

Users can authenticate using methods they already know and trust—email, social login, or passkeys. There’s no need to learn new security practices or manage complex cryptographic material.

Flexible Recovery

Multiple backup and recovery options ensure users never lose access to their assets. Whether through cloud storage, device backups, or enterprise-managed solutions, recovery is designed to be both secure and user-friendly.

Cross-Platform Consistency

The same wallet experience is available across all devices and platforms. Users can seamlessly transition between web, mobile, and desktop applications while maintaining full access to their assets.

No Seed Phrases

Eliminates the complexity and security risks associated with traditional wallet recovery methods. Users don’t need to safely store and manage long strings of random words that could be lost or compromised.

Developer Benefits

Customizable Security

Configure thresholds and party arrangements based on your specific security requirements. Start with a simple 2-of-2 setup and scale to more complex configurations like 3-of-5 for enterprise applications.

Enterprise Integration

Support for customer-controlled shares enables enterprise-grade security and compliance. Organizations can maintain oversight of wallet operations while leveraging Dynamic’s infrastructure.

Scalable Architecture

Handle millions of wallets efficiently without compromising security or performance. The MPC approach scales horizontally, making it suitable for applications of any size.

Compliance Ready

Built-in security controls and audit trails help meet regulatory requirements. The cryptographic nature of MPC operations provides the transparency needed for compliance while maintaining security.

Real-World Applications

DeFi and Trading

High-frequency trading and DeFi operations benefit from MPC’s speed and security. Users can execute complex financial operations without the delays associated with traditional multi-signature schemes.

Gaming and NFTs

Gaming applications can provide seamless wallet experiences while maintaining security. Users can quickly sign transactions for in-game purchases or NFT trades without compromising their overall wallet security.

Enterprise Solutions

Organizations can implement sophisticated wallet management with multiple stakeholders while maintaining security and compliance requirements. The flexible threshold schemes allow for complex organizational structures.

Cross-Chain Operations

MPC’s support for multiple signature schemes enables seamless operation across different blockchain networks. Users can interact with Ethereum, Solana, Bitcoin, and other chains using the same wallet infrastructure.

Comparison with Alternatives

Traditional Single-Key Wallets

  • MPC Advantage: No single point of failure, distributed trust
  • Traditional Limitation: Complete compromise if private key is exposed

Multi-Signature Wallets

  • MPC Advantage: Faster signing, no on-chain transactions for setup
  • Multi-Sig Limitation: Slower operations, higher gas costs

Hardware Wallets

  • MPC Advantage: Cross-platform compatibility, flexible recovery
  • Hardware Limitation: Device dependency, limited recovery options
