The Challenge: Contract deployment requires:

  • ABI (Application Binary Interface) file upload
  • WASM (WebAssembly) bytecode upload
  • Target account specification
  • Transaction signing with proper permissions
  • Clear feedback on success/failure

The Solution: Graphical contract upload interface:

  • Basic ABI/WASM file upload (PR #451)
  • Standalone /upload page for dedicated workflow (PR #453)
  • Session-based visibility (PR #454)
  • Upload to any account (not just user’s accounts)
  • Visual upload zone with dashed outline (PR #487)

Work Completed:

Technical Impact: Empowers developers to deploy contracts through graphical interface without command-line tools. Generic /upload endpoint supports multisig deployments and managing accounts without direct key access. Improves developer onboarding by reducing technical barriers. Continues Unicove’s evolution into comprehensive development platform.

Context: Blockchain transactions contain technical action data difficult for non-technical users to understand.

The Business Need: Transaction transparency essential for user trust and security. Users must understand what they’re signing. Technical action data (JSON with type names and hex data) incomprehensible to most users.

The Solution: Human-readable action summaries:

  • Transform technical action data into plain language
  • Structured table presentation for complex data
  • Context-appropriate descriptions
  • Integration throughout transaction views

Work Completed:

Technical Impact: Major usability improvement making blockchain transactions understandable to non-technical users. Users can review transaction contents in plain language before signing. Essential for mainstream adoption - users won’t sign transactions they can’t understand. Improves security by enabling informed consent.

Dynamic Open Graph Images for SEO

Context: Social media sharing and SEO require Open Graph metadata with preview images.

The Business Need: Links shared on Twitter, Discord, Telegram show rich previews when proper OG metadata present. Static OG images don’t reflect page content. Dynamic images with page-specific content improve click-through rates and professional appearance.

The Solution: Dynamic OG image generation:

  • Serialize page data into URI parameters
  • API endpoint proxies to unicove-og-image-gen service
  • Generator creates custom images with page data
  • Returns generated image for social preview
  • Each page type can have custom OG template

Work Completed:

Technical Impact: Significant SEO and social media improvement. Shared links display rich previews with context-specific information (account names, transaction IDs, block numbers). Professional appearance on social platforms. Improves click-through rates from social media. Demonstrates Unicove’s attention to marketing and growth details beyond core functionality.

Mnemonic Recovery in Web Authenticator

Context: Web Authenticator needed account recovery mechanism for production deployment.

The Business Need: Users must be able to recover accounts if they lose device, switch browsers, or clear browser data. Without recovery mechanism, account loss means permanent loss of funds. Recovery capability critical for production deployment.

The Challenge: Web Authenticator uses WebAuthn (biometric) authentication. WebAuthn credentials tied to device/browser. Credentials cannot be exported or transferred. Need separate recovery mechanism independent of WebAuthn.

The Solution: Mnemonic phrase backup and recovery:

  • Generate BIP39 mnemonic (12/24 word phrase) from account key
  • Users write down mnemonic for backup
  • Recovery flow accepts mnemonic to restore account
  • Import account on new device using mnemonic
  • Complements WebAuthn convenience with recovery safety net

Work Completed:

Technical Impact: Critical production readiness milestone. Mnemonic recovery provides familiar, industry-standard account restoration method. Users can confidently use Web Authenticator knowing they can recover accounts. Essential for production deployment - users won’t adopt wallet without recovery mechanism. Balances WebAuthn convenience with traditional crypto recovery approach.

The Business Need: Some users require hardware wallet security for high-value accounts. Hardware wallets provide maximum security through offline key storage. Web Authenticator focused on convenience (WebAuthn), but professional users need hardware security option.

The Solution: Ledger plugin architecture:

  • Created wharfkit/wallet-plugin-ledger package
  • Support multiple transport methods (WebUSB, WebHID, WebBLE, node-hid)
  • Integrated into Web Authenticator
  • Users can sign with Ledger while using cloud wallet interface
  • Bridges convenience and maximum security

Work Completed:

Technical Impact: Expands Web Authenticator security options. Users can combine cloud wallet convenience with hardware wallet security. Attractive to institutional users and high-net-worth individuals requiring hardware security. WebBLE support enables mobile Ledger connectivity. Demonstrates flexible plugin architecture supporting multiple security models in single interface.

Status: IN DEVELOPMENT - not production-ready yet, but foundation established.

Anchor Mobile Android Stability Sprint

Context: May saw unusual high activity in Anchor Android (17 PRs) addressing accumulated technical debt and stability issues.

The Challenge: Maintenance mode applications still accumulate bugs and issues. User reports indicated memory leaks, authentication hangs, key handling failures, and translation errors. Vaulta rebrand needed implementation.

The Solution: Focused maintenance sprint addressing backlog:

  • Memory Management: Fixed camera listener leak (PR #739)
  • Authentication Reliability: Fixed JS hang during auth (PR #740), proper async key handling (PR #741)
  • Key Management: Never delete keys policy (PR #735), allow deleting accounts without OKC (PR #734)
  • Vaulta Migration: Complete EOS→Vaulta rebrand (PR #728)
  • UI/UX: Alignment fixes (PR #744), PIN label updates (PR #729)
  • Localization: Critical Chinese translation fixes (PR #742)
  • Data Integrity: Fixed settings date handling (PR #743)

Work Completed: 17 PRs total in May addressing stability, reliability, and branding.

Technical Impact: Significantly improved Anchor Android stability and user experience. Memory leak fix prevents gradual performance degradation. Authentication hang fix prevents frustrating app freezes. Key management improvements protect users from data loss. Vaulta migration aligns with ecosystem rebrand. High PR count suggests focused maintenance sprint clearing accumulated backlog. Demonstrates ongoing commitment to maintenance-mode products.

Vaulta Rebrand Completion Across Stack

Context: April began Vaulta rebrand in Unicove. May completed rebrand across full stack.

The Coordination Challenge: Rebrand requires changes across multiple layers:

  • Frontend applications (Unicove, Anchor Mobile)
  • SDK/Library layer (WharfKit common)
  • Backend services and configurations
  • Documentation and external materials

The Solution: Coordinated rebrand across stack:

  • WharfKit SDK: Added Vaulta chain definition (wharfkit/common PR #4)
  • Mobile Apps: Anchor Android Vaulta migration (greymass/anchor-mobile-android PR #728)
  • Web Apps: Unicove already completed in April (PR #430)
  • Network Configurations: Chain metadata, endpoints, token info

Work Completed:

Technical Impact: Completes Vaulta rebrand across entire product ecosystem. Users see consistent Vaulta branding across web, mobile, and SDK layers. Central chain definition in wharfkit/common ensures all WharfKit-powered dapps support Vaulta with standard configuration. Demonstrates coordinated execution across multiple teams and repositories. Reflects network’s post-VF evolution and new identity.

WharfKit Wallet Plugin Ecosystem Expansion

Context: May created two new wallet plugins expanding WharfKit’s supported wallet ecosystem.

The Strategy: Comprehensive wallet support through plugin architecture. Each wallet plugin enables WharfKit dapps to support different user preferences and regional ecosystems.

New Plugins Created:

  • wallet-plugin-ledger: Hardware wallet security for institutional/high-value users
  • wallet-plugin-imtoken: Popular Asian mobile wallet expanding regional reach

Technical Impact: Expands potential user base for WharfKit-powered dapps. Developers using WharfKit can support diverse wallet preferences with minimal integration effort. Plugin architecture demonstrates extensibility - adding wallet support doesn’t require core library changes. Ledger plugin brings maximum security option. imToken plugin enables Asian market access.
