MPC-Powered Wallet-as-a-Service Infrastructure

Silence Laboratories provides developer infrastructure and SDKs for embedding advanced MPC wallet functionality into Web3 applications, reducing onboarding friction while maintaining cryptographic security.

Silent Shard Snap: MetaMask Extension Integration

Silent Shard Snap enables distributed self-custodial wallets within the MetaMask browser extension, leveraging ultra-fast MPC technology to provide 2FA-like transaction approval between browser and mobile phone.

User Experience Features

Super Secure Transaction Approval - Browser and phone work together using MPC to generate signatures without ever exposing the complete private key on any single device, eliminating single points of failure.

Utmost Ease of Use - Despite sophisticated cryptography underneath, the experience is remarkably simple - just approve transactions on your phone. No complex seed phrase management required.

Enhanced Recovery Options - Integration with password managers (Google, Apple) for convenient recovery mechanisms while maintaining security through distributed key architecture.

MetaMask Integration - Seamless integration with the world's most popular Web3 wallet, allowing users to leverage MetaMask's extensive ecosystem with enhanced MPC security.

Industry Recognition

Highlighted by Alex Jupiter, Accounts Group Lead at MetaMask/Consensys: "Silent Shard in particular offers a novel 2FA like experience between MetaMask Extension and their Silent Shard app to approve transactions, which is all powered by some cutting edge MultiParty Computation (MPC) Cryptography."

Silent Shard: Wallet Infrastructure SDK

Silent Shard provides developer libraries for building next-generation wallet infrastructure with true self-custody, eliminating single points of failure while maintaining excellent user experience.

Deployment Architectures for Developers

Browser and Plugin Wallets {2,2} - 2FA-like security between browser and mobile with sub-20ms signature generation.

Server + Phone {2,2} - Enterprise-grade mobile authentication for application-embedded wallets.

Server + Phone {T,N} - Flexible threshold configurations for complex organizational requirements.

Use Cases

Universal MPC 2FA Authenticator - Brings 2FA security to Web3 through simple 'swipe to approve' transactions from browser-based wallets and dApps.

Wallet Infrastructure - Powers next-generation crypto wallets with distributed control over digital assets and seamless user experience.

Silent Network: Customized Onboarding Infrastructure

Silent Network enables developers to build wallet experiences with flexible authentication mechanisms and permissionless access.

Onboarding Capabilities

Customized Authentication - Organizations can choose authentication mechanisms including social login, passkeys, FaceID (coming soon), and biometrics (coming soon). Users can access wallets from any device.

Permissions and Automations - Library of pre-created permissions or custom permission creation for user wallets. Integrates with external APIs and device data.

Session Key Networks - Temporary signing keys with MPC security for application-specific operations, enabling gasless transactions and improved UX.

Chain Agnostic - Supports all blockchain networks and signature types (ECDSA and EdDSA), enabling true multi-chain keyless wallet infrastructure.

Technical Performance

Leverages the world's fastest MPC-TSS implementation with <20ms compute time for {3,5} sign operations, enabling real-time transaction processing for embedded wallet applications at scale.
