DiosDelRayo submits CCS proposal to create offline signing library for XmrSigner

DiosDelRayo (vThor)¹ has submitted a new CCS proposal² looking to create an offline signing library³ in an effort to bring XmrSigner⁴ to production readiness and also provide a foundation for future hardware wallet development:

This proposal aims to create a minimal library for offline signing on air-gapped devices, focusing on essential features [..] This library will significantly improve XmrSigner’s performance, security, and usability while opening doors for more diverse Monero hardware wallet solutions in the future.

Total funding: 97 XMR (240 hours).

ETA: 2 months.

Proposed objectives overview

• Comprehensive documentation
• Quick start guide for offline and hardware wallet developers
• Documentation of challenges in stripping down and cross-compiling
• Buildroot package for easy target system integration
• Python module for library usage
• Test code
• Modification of XmrSigner to use this new library

It is worth noting that DiosDelRayo has recently closed their previous proposal⁵ to modularize the Monero codebase, but is still working on completing the XmrSigner CCS⁶.
