Web Authenticator Migration to Sealed-Messages Library

Integration: Web Authenticator migrated to shared sealed-messages library for encrypted communication between wallet and applications.

Technical Relationship: Web Authenticator requires secure, encrypted communication with dapps for identity proofs, transaction requests, and sensitive data exchange. Originally implemented custom encryption. Sealed-messages library provides shared, tested encrypted messaging using blockchain keys.

How They Work Together:

  • Sealed-Messages Library: Implements encryption/decryption using blockchain key pairs (no additional key management)
  • Web Authenticator (PR #76): Migrated to sealed-messages replacing internal encryption implementation
  • Communication Flow: Applications encrypt messages using recipient’s public key → Web Authenticator decrypts using private key
  • Blockchain Key Reuse: Leverages existing blockchain keys for encryption, no additional key management burden

Encryption Architecture:

  1. Key Material: Uses existing blockchain key pairs (Antelope keys, WebAuthn keys)
  2. Message Sealing: Sender encrypts message with recipient’s public key
  3. Message Unsealing: Recipient decrypts with their private key
  4. Use Cases: Secure wallet-dapp communication, private account-to-account messaging, confidential data exchange

Benefit: Eliminates duplicate encryption implementations across products. Any Greymass product can now use sealed-messages for encrypted communication ensuring consistent, tested cryptography. Web Authenticator gains reliability from shared library. Library enables new use cases beyond wallet communication - any blockchain account can send encrypted messages to other accounts using existing keys.

Unicove Architecture Improvements

Context: July included two significant architectural improvements enhancing Unicove’s security and maintainability.

Coinbase Onramp Security Migration

Business Need: Unicove integrates Coinbase onramp for fiat-to-crypto purchases. Initial integration exposed credentials client-side creating security risk. Heavy SDK dependencies bloated bundle unnecessarily. Production deployment requires secure credential handling and optimized bundle size.

Technical Challenge: Coinbase onramp integration initially exposed appId and address parameters client-side allowing credential exposure. cdp-sdk library included dependencies for all supported networks (Ethereum, Polygon, etc.) despite Unicove only needing Antelope support - unnecessary bundle bloat. Refactoring required without breaking existing functionality.

Solution - PR #515: Major refactoring moving credential handling server-side:

  • Created API route generating sessionToken server-side
    • Sensitive credentials never exposed to client
    • Server-side JWT generation for secure tokens
  • Removed cbpay-js convenience library
    • Manual URL building provides better control
    • Eliminates unnecessary abstractions
  • Replaced cdp-sdk with minimal no-dependency JWT library
    • Significant bundle size reduction
    • Only includes what’s needed for Antelope
    • No unnecessary network dependencies
  • Closed issue #512

Technical Impact:

  • Critical security improvement - credentials never exposed client-side
  • SessionToken approach more secure than parameter passing
  • Significant bundle size reduction eliminating heavy SDK
  • Better security posture for fiat onramp integration
  • Manual URL building provides better control and transparency
  • Reduced dependencies lower maintenance burden

Component Library Integration

Business Need: Unicove contained duplicate UI components also existing in other projects. Code duplication creates maintenance burden. Component improvements must be replicated across projects. Inconsistent implementations lead to bugs. Shared component library provides single source of truth for UI components.

Technical Challenge: Unicove built custom components over time creating implementation duplication. Component library (unicove-components) developed separately. Integration requires identifying shared components, migrating to library versions, ensuring visual/functional consistency, removing duplicate code. Large refactoring touching many files across project.

Solution - PR #504: Major refactoring integrating unicove-components library:

  • Replaced custom components with shared library components
    • Button components
    • Input components
    • Display components
    • Layout components
  • Established consistent component usage across projects
  • Reduced code duplication significantly
  • Consolidated UI component development in shared library

Technical Impact:

  • Significant maintainability improvement through shared components
  • Component library provides tested, consistent implementations
  • Component improvements benefit all consumers automatically
  • Reduces Unicove codebase size through deduplication
  • Establishes foundation for shared design system across ecosystem
  • Future UI work happens in library benefiting multiple projects

Timing: Coordinates with unicove-components PR #8 adding warning/destructive color themes. New themes immediately available in Unicove through integration.

Link: https://github.com/greymass/unicove/pull/504

Work Completed: 2 major architectural PRs improving security and maintainability.

Technical Significance: Both improvements represent mature architectural thinking. Security migration demonstrates proactive security posture preventing credential exposure. Component library integration shows commitment to reducing technical debt through shared infrastructure. Investments pay dividends long-term through reduced maintenance burden, improved reliability, and faster feature development through shared components.

Architectural Maturity: Refactoring existing working code for security and maintainability demonstrates mature development priorities. Short-term effort investment for long-term reliability and maintenance benefits. Both changes improve code quality without adding user-facing features - important maintenance work strengthening foundation.

WharfKit Sealed Messages Library Creation

Context: New sealed-messages library created July 26 extracting encrypted messaging into shared infrastructure. Web Authenticator migrated same day demonstrating immediate production usage.

Business Need: Encrypted communication between wallets and dapps requires consistent, secure implementation. Multiple applications need encrypted messaging (Web Authenticator, other wallets, dapps). Duplicating encryption implementation across applications creates maintenance burden and security risk through implementation drift. Shared library ensures consistent, well-tested encryption across ecosystem.

Technical Challenge: Implementing secure encrypted messaging using blockchain key infrastructure. Sender must encrypt message that only receiver can decrypt. Must use existing Antelope public/private keys avoiding separate encryption key management. Cryptographically secure approach preventing eavesdropping. Shamir’s secret sharing provides appropriate cryptographic foundation.

Solution Implemented: New sealed-messages repository providing encryption library:

The Technology:

  • Uses Shamir’s secret sharing cryptographic algorithm
  • Integrates with WharfKit Antelope public/private key system
  • Sender encrypts message using their private key, receiver’s public key, and nonce
  • Receiver decrypts using their private key, sender’s public key, and same nonce
  • Cryptographically secure approach leveraging existing blockchain key infrastructure

The Integration:

  • Web Authenticator immediately migrated to use library (PR #81)
  • Migration same day as repository creation
  • Demonstrates library created to extract functionality from existing implementation
  • Shared library ensures consistent encryption across ecosystem

The API:

// Encryption
sealMessage(
  senderPrivateKey: PrivateKey,
  receiverPublicKey: PublicKey,
  nonce: string,
  message: string
): string

// Decryption
unsealMessage(
  receiverPrivateKey: PrivateKey,
  senderPublicKey: PublicKey,
  nonce: string,
  encryptedMessage: string
): string

Work Completed: Repository created July 26, Web Authenticator migrated PR #81 same day.

Technical Impact: Establishes encrypted messaging foundation for WharfKit ecosystem. Enables secure communication features across wallets and dapps. Shared implementation ensures interoperability - different applications can communicate using same encryption standard. Reduces duplication by extracting into reusable library. Foundation for future encrypted features (private messages, secure metadata, confidential transactions). Leverages existing key infrastructure avoiding separate key management.

Architectural Pattern: Follows WharfKit pattern of shared infrastructure libraries. Similar to earlier extractions:

  • wharfkit/webauthn (June 2025) - WebAuthn key management
  • wharfkit/antelope - Core blockchain primitives
  • wharfkit/session-kit - Session management

Demonstrates maturity in recognizing reusable patterns and extracting into shared code. Benefits entire ecosystem not just single application. Concentrated testing effort ensures reliability. Consistent behavior across products.

Cryptographic Foundation: Shamir’s secret sharing established cryptographic algorithm providing security properties needed for encrypted messaging. Using blockchain keys directly avoids separate encryption key management simplifying UX. Nonce prevents replay attacks and provides message uniqueness.

Future Potential: Foundation enables encrypted features across ecosystem:

  • Wallet-to-dapp secure communication
  • Wallet-to-wallet private messaging
  • Encrypted metadata storage
  • Secure parameter passing in URLs
  • Confidential transaction data

  • User clicks login, scans QR with PayCash wallet, authentication completed
  • Cloud-only solution requiring no mobile app installation
  • Supports light/dark themes, TypeScript, cross-platform browsers
  • Clear documentation of authentication-only limitation

The Limitation: Important notice in README:

  • Plugin only supports authentication (login), NOT transaction signing
  • PayCash wallet doesn’t currently support ESR for transaction signing via QR
  • Plugin can identify users but cannot sign transactions
  • Can be updated if PayCash adds ESR support in future

The Value Despite Limitation: Authentication-only support still valuable for use cases:

  • Identifying users without requiring transaction signing
  • Gating content or features by account ownership
  • Reading user data without modifying blockchain
  • Regional wallet support where PayCash popular
  • Dapps with readonly functionality not requiring transactions

Work Completed: Repository created July 13, implementation pushed July 22.

Technical Impact: Expands WharfKit wallet plugin ecosystem adding regional wallet support. Demonstrates plugin system flexibility - can support authentication-only wallets. Limitation clearly documented preventing user confusion about capabilities. Can be updated if PayCash adds ESR support showing extensibility. Regional wallet support improves adoption in PayCash-popular markets supporting global reach.

Plugin Ecosystem Growth: Adds to growing list of WharfKit wallet plugins:

  • Anchor (full-featured native wallet)
  • Web Authenticator (browser-based cloud wallet)
  • MetaMask Snap (browser extension)
  • Wombat (mobile/web wallet)
  • TokenPocket (multi-chain wallet)
  • Ledger (hardware wallet)
  • CloudWallet (cloud-based)
  • PayCash (authentication-only, QR-based)

Each plugin expands user choice and adoption potential. Regional wallets like PayCash important for global reach. Diverse wallet support accommodates different user preferences and security requirements.

Authentication Flow:

  1. Dapp presents wallet options including PayCash
  2. User selects PayCash login option
  3. Plugin displays QR code
  4. User scans with PayCash wallet app
  5. Authentication completes, user identified
  6. Dapp can read user account data but cannot request transaction signatures

Technical Details: Implements WharfKit Session Kit wallet plugin interface for authentication-only flow. Uses QR code authentication mechanism. Proper session management and cleanup. Includes test application for development. TypeScript support with full typing.
