Technical Activity Report

February 2026

February 2026 delivered session keys across the full application stack, from WharfKit core libraries through the Web Authenticator and its wallet plugin. Roborovski matured with a CI/CD pipeline, performance tuning, and new API endpoints on the dev branch. Unicove continued on its robo2 branch with a redesigned contract table browser, premium account names, reworked transaction summary pages, and a MetaMask-to-Vaulta wallet rebrand. Several new prototype repositories explored real-time chat, forum, and light account use cases built on the emerging session key and streaming infrastructure.

Key Achievements:

  • Implemented session keys in Web Authenticator with security hardening for signing request context detection (PRs #226, #228)
  • Coordinated session key support across wharfkit/session (send_transaction2), wharfkit/antelope (error handling), wharfkit/web-renderer (prompt reset), and wallet-plugin-web-authenticator (key rename + multichain)
  • Established Roborovski CI/CD pipeline via GitHub Actions, fixing a bad allocation growth OOM bug discovered during test runs
  • Added Roborovski /usage and /action API endpoints on dev branch; extracted streaming proxy into standalone service
  • Redesigned Unicove contract table browser with large data field handling and reworked transaction summary page
  • Released wharfkit/transact-plugin-resource-provider v2.0.0-rc1 with RAM-aware fee calculation

Technical Significance: The session key rollout completed a coordinated feature that originated in WharfKit during December 2025, now reaching the Web Authenticator application layer where signing request security and trusted origin handling required careful design. The 30-comment discussion on PR #228 shaped the security model for automatic signing across popup, mobile, and direct ESR link contexts. New prototype repositories (chat, forum) validated the session key and streaming infrastructure under real-time messaging workloads.

Session Keys Across the Stack

Repositories: greymass/web-authenticator, wharfkit/session, wharfkit/antelope, wharfkit/web-renderer, wharfkit/wallet-plugin-web-authenticator

Previous Context: See December 2025 for initial session key implementation in WharfKit session, web-renderer, and signing-request packages.

December 2025 introduced session key logic in the WharfKit SDK layer. February brought that feature into the application tier:

  1. greymass/web-authenticator received session key support (PR #226) followed immediately by security hardening (PR #228) that added context detection for signing requests arriving via popups, mobile apps, or direct ESR links
  2. wharfkit/session added send_transaction2 support on its sessionkey branch (PR #102), providing improved error handling for session key transactions
  3. wharfkit/antelope standardized send_transaction2 error handling in the core library, released as v1.2.0-rc2
  4. wharfkit/web-renderer updated session key prompt handling with conflict/mismatch reset logic, released as v2.0.0-rc7
  5. wharfkit/wallet-plugin-web-authenticator added multichain support and key rename (PR #13), released as v0.5.1

The security discussion on Web Authenticator PR #228 (30 comments) shaped the trust model for automatic signing: sealed messages provide a security layer over raw ESR payloads, and a dApp registry concept was discussed for verified application badges.

Roborovski Infrastructure and Unicove Integration

Repositories: greymass/roborovski, greymass/unicove

Previous Context: See January 2026 for open-source migration and full-stack integration across four layers.

February advanced both the infrastructure and consumer sides of the Roborovski stack:

  1. greymass/roborovski established CI/CD with GitHub Actions, applied performance tuning (buffer sorting for GC pressure reduction, Pebble tuning), and extracted the streaming proxy into a standalone service. New /usage and /action endpoints landed on the dev branch.
  2. greymass/unicove continued on its robo2 branch with 28 commits: ABI decoding fallback, multisig proposal loading from the msig API with chain fallback, contract table browser redesign, and transaction summary page rework.

The Unicove msig proposal loading now sources data from Roborovski’s msig API first, falling back to direct chain queries, demonstrating the API-first architecture where Roborovski serves as an indexing layer between the blockchain and application.

Communications Proof-of-Concept

Repositories: greymass/chat-prototype, greymass/forum-protoype

Two new repositories were created as proof-of-concept messaging applications built on a smart contract designed to showcase recent network features under demanding, real-time conditions. Both the chat-prototype and forum-protoype exercise the combined infrastructure stack: Web Authenticator onboarding, session keys for low-security actions, resource provider for transaction resources, and Roborovski-based real-time streaming APIs for live updates.

Resource Provider Stack

Repositories: greymass/resource-provider, wharfkit/transact-plugin-resource-provider

The server-side resource provider received a major rewrite during the same week the client-side WharfKit plugin shipped v2.0.0-rc1. The server added transaction cosigning with usage tracking, rewrote the contract cache, and added v1/provider API compatibility. The client plugin updated fee calculations to account for RAM actions and improved token detection. Together these form the full stack for fee-free transaction support.

Light Account Prototype

Repositories: greymass/lightaccountdemo, greymass/faucet

A separate prototype explored light accounts — no-account addresses capable of receiving tokens without a full blockchain account. The lightaccountdemo provides the front-end prototype while the faucet service distributes tokens for testing.

Repository: https://github.com/greymass/web-authenticator Activity: 2 PRs merged Previous Context: See December 2025 for Ledger no-op transaction fix Related Work: See wharfkit/session, wharfkit/wallet-plugin-web-authenticator

Overview

February introduced session keys into the Web Authenticator, followed by security hardening that addressed signing request trust across different embedding contexts (popups, iframes, mobile apps, direct ESR links).

Pull Requests

Major Changes

#226 - Session Keys (link) Merged: 2026-02-12 | 2218 additions, 555 deletions across 22 files

Description: Session key implementation in the Web Authenticator. Session keys allow applications to sign certain actions automatically without requiring user approval for each transaction. This builds on the session key feature introduced in WharfKit during December 2025. Includes split signing paths for session key flows and custom session key request handling.

Impact: Applications integrating with Web Authenticator can now request session keys for low-security actions, reducing wallet prompt fatigue for high-frequency use cases.

#228 - Session Keys + Security (link) Merged: 2026-02-13 | 2404 additions, 553 deletions across 29 files

Description: Security hardening on top of the session keys implementation. Added security context detection, trusted origin handling via TRUSTED_ORIGIN, and request safety classification for signing requests arriving from different contexts.

Discussion (30 comments): See Notable Technical Discussions for full summary.

Impact: Establishes the trust model for automatic transaction signing. Sealed messages replace raw ESR payloads for security. Debug page retained for testing across embedding environments (Unicove, iframe, popup, mobile).

Notable Technical Discussions

Discussion: Web Authenticator Security Model for Session Keys

Location: greymass/web-authenticator PR #228 Comment Count: 30 comments

Topic: How to handle transaction signing request security across different embedding contexts (popups, mobile apps, direct ESR links).

Key Points:

  • Whether signing requests arriving without an opener context (e.g., ESR links on business cards or websites) should be treated as unsafe by default
  • Whether to disable request signing entirely outside mobile app or popup contexts
  • Concept of a dApp registry for trusted application verification, providing verified badges rather than showing warnings for unregistered sources
  • The approach favors instilling trust for verified apps over creating friction for unverified ones

Decision: Merged with sealed messages replacing raw ESR payloads as the security layer. The TRUSTED_ORIGIN mechanism provides consistent origin validation. The dApp registry concept remains a consideration for verified application badges. The consensus favored preserving the open nature of ESR links while adding security through sealed message verification.
