Unified Account Creation Infrastructure Integration
Anchor Mobile Android integrated with centralized account creation infrastructure:
Integration Stack:
-
greymass/account-creation-portal - Centralized account creation service
- #26: Account name validation improvements
- Provides consistent validation, premium name handling, resource provisioning
- Centralized error handling and retry logic
-
greymass/anchor-mobile-android - Mobile wallet integration
Technical Relationship: Mobile wallet connects to centralized account creation infrastructure:
- Portal layer: account-creation-portal provides centralized account creation logic (validation, premium names, resource provisioning)
- Mobile layer: Anchor Android consumes portal API for streamlined account creation flow
- Infrastructure layer: Portal connects to backend services (Sextant) for blockchain provisioning
Strategic Pattern: Unifying account creation across all Greymass products (Anchor, Web Authenticator, Unicove, MetaMask Snap) using shared infrastructure. Single codebase for complex account creation logic ensures consistency and enables rapid deployment of improvements across all products.
Impact: Consistent onboarding experience across all products. Centralized maintenance reduces duplicate code. Bug fixes and improvements benefit entire product ecosystem simultaneously.

Major Changes
#384 - Adding support for multisig accounts (link)
Merged: 2025-02-24 | Comments: 21
Description: Major feature addition bringing comprehensive multisig functionality to Unicove, including:
- Multisig wallet plugin for WharfKit session management
- Account authority page for visualizing permission structures and hierarchies
- Multisig session display for managing connected multisig accounts
- Multisig configuration options in settings page
- Rework of resources display to accommodate multisig contexts
- DateTime input components for time-delayed proposals
- Support for time.eosn contract checktime action in multisig transactions
- Improved activity filtering to prevent duplicate transaction display
- PWA manifest reference cleanup
Discussion (21 comments): The PR included 1 general discussion thread and 20 review comments addressing implementation details, edge cases, and UX considerations for complex multisig permission structures.
Impact: This work transforms Unicove into a full-featured multisig account management interface, eliminating the need for command-line tools or separate interfaces. It complements existing msigs.io integration. Users can now view permission hierarchies, create proposals, manage approvals, and interact with complex authority structures directly through Unicove’s interface.
Technical Context: Multisig accounts on Antelope blockchains use complex permission structures with multiple authorities, weighted keys, thresholds, and time delays. This implementation required careful state management, robust ABI decoding (see PR #392), and sophisticated UX design to make these capabilities accessible to non-technical users.
#355 - Network Abstraction (link)
Merged: 2025-02-07 | Comments: 1
Description: Architectural change to abstract network configuration, making it easier to support multiple Antelope blockchains with different configurations, features, and capabilities.
Impact: This architectural change makes Unicove truly multi-chain capable by removing hardcoded network-specific logic. It enables dynamic configuration through environment variables, chain-specific feature flags, flexible token and resource handling per network, and easier addition of new Antelope chains. Follow-up work in PR #361 (Additional chain abstraction) and PR #359 (Reworked environmental variables) extended these capabilities.
Breaking Changes: None for end users, but developers/operators now configure network capabilities through environment variables rather than code changes.
#374 - Actions/transactions rework (link)
Merged: 2025-02-19 | Comments: 1
Description: Architectural rework of how actions and transactions are handled within Unicove, improving the underlying transaction composition and submission flow.
Impact: Improved transaction handling architecture supporting the multisig functionality and future transaction-related features. Lays groundwork for more complex transaction types and better error handling.
#371 - Gifted RAM + State refactoring (link)
Merged: 2025-02-17
Description: Added gifted RAM functionality allowing users to purchase RAM for other accounts, along with state management refactoring to support the new feature.
Impact: Enables users to provision resources for new accounts or help other users, improving the onboarding experience and account management capabilities.
#344 - Smart Contract API (link)
Merged: 2025-02-04
Description: Continued integration of smart contract-based API endpoints from the unicove-contracts repository (created January 2025).
Impact: Reduces dependency on native blockchain APIs by moving functionality to smart contracts. This approach provides more reliable, cacheable data access and enables features not available through standard RPC APIs.
Technical Context: Part of ongoing architectural shift toward contract-based data access initiated in January with the unicove-contracts repository.

greymass/web-authenticator
Repository: https://github.com/greymass/web-authenticator
Activity: 2 PRs merged | Cloudflare edge backend completion
Overview
February completed the major backend infrastructure transition started in January 2025, moving Web Authenticator from a purely client-side application to a hybrid client-server architecture deployed on Cloudflare’s edge network.
Pull Requests
#4 - Adding Cloudflare backend (link)
Merged: 2025-02-21 | Comments: 2
Description: Implemented Cloudflare-based backend infrastructure, building on the Express backend work from January. Enables Web Authenticator to run on Cloudflare’s edge network (Workers/Pages) while maintaining database connectivity for account tracking.
Impact: Provides scalable, globally-distributed backend infrastructure for Web Authenticator’s account management features while maintaining WebAuthn security benefits. Enables features like account recovery and cross-device access by storing encrypted account data on the backend, while keeping private keys exclusively in user devices via WebAuthn.
Architecture:
- Cloudflare Workers/Pages for edge deployment
- Database connectivity for account tracking and recovery
- WebAuthn security model preserved (private keys never leave device)
- Global edge distribution for low-latency access
#9 - Refactoring state (link)
Merged: 2025-02-26
Description: Refactored state management architecture to support the new backend infrastructure and improve data flow throughout the application.
Impact: Completes the architectural transition by adapting the client-side state management to work with the Cloudflare backend, enabling proper synchronization between client and server state.
Technical Context
Previous Architecture: See January 2025 for the Express backend infrastructure transition initiated last month.
February Completion: Migrated January’s Express backend to Cloudflare edge deployment (PRs #4, #9), completing the architectural transition to hybrid client-server with global edge distribution.
Status: Architecture transition completed February 2025. WebAuthn security model preserved (device-resident private keys) while enabling backend-assisted recovery and cross-device access.
