Project Overview 📄​

Overview​

Enhancing Ledger Polkadot Universal App Compatibility for Emerging Substrate Ecosystems​

This project expands the compatibility of the Polkadot Universal App to support the evolving landscape of Substrate-based blockchain networks, particularly those with specialized configurations. This initiative addresses the growing need for secure hardware wallet support for projects like Mythical Games and the future AssetHub evolution, codenamed "Plaza,".

Project Details​

This upgrade will deliver the following key enhancements:

  • Expanded Cryptographic Support: Implement alternative cryptographic signature methods, specifically ECDSA and Keccak-256 hashing, to accommodate the requirements of emerging networks. This involves modifications to both the Ledger app and the associated JavaScript (JS) package.
  • Variable Account Identifier Support: Adapt the application to handle varying account identifier lengths, including the 20-byte address format, which is essential for compatibility with specific networks. This will require changes to both the Ledger app and the JS package.
  • Adaptation of signRaw function Extend signRaw functionality to support ecdsa
  • Testing and Integration: Develop comprehensive integration tests and implement Continuous Integration (CI) pipelines to ensure the stability and reliability of the enhanced application.
  • Third Party Security Audit: Conduct a thorough security audit by an auditor selected from Ledger SAS's approved list. This audit is a requirement for publication on the Ledger Live platform, as per Ledger's established procedures. Ledger's Third-Party Security Assessment Report Guidelines
  • Ledger Release Management: Manage the submission process and release process through Ledger, ensuring effective communication and coordination. While Zondax will facilitate the review process, Ledger's release timeline remains outside of Zondax's direct control.

Note: This upgrade maintains the existing Polkadot derivation path within the Ledger app; no modifications are required.
