CB-2Q23-04.2 : sBTC Stacks-Signer Support for Mobile
Discussed in https://github.com/stacksgov/Stacks-Grant-Launchpad/discussions/843
Originally posted by will-at-stacks March 17, 2023
Introduction:
Maintaining a well-decentralized graph of Stacks follower and mining nodes is important to the health of the Stacks network. Stacks 3.0 will require stackers to run a new signing application. Current users who are unable to securely run a signer application may be incentivized to delegate their signing responsibility. While potentially more convenient, delegating signing responsibility reduces the number of independent entities responsible for securing the sBTC threshold wallet and lowers decentralization.
Critical Bounty Mission Statement:
To address these challenges, this Critical Bounty seeks a solution that provides sBTC Stacks-Signers a simple web-app interface by which they can sign transactions related to:
- Depositing funds
- Withdrawing funds
- Casting votes
- Propose elections (related to sBTC script security, fee recovery parameters, and Nakamoto release related block production rules)
This will allow a wide range of Stackers/Signers to participate directly in the sBTC Threshold Signature protocol in a trustless manner. This application will have a high security consideration.
Functionality / Deliverables (shall include, but not be limited to):
- Mirror functionality outlined in CB-23Q2-02.1
- Debugging issues with building on iOS and Android
- Packaging and deploying to the iOS and Android App Store
- Building a UI app to manage the signer
- Notification & Alert system
- Product 'roadshow', feedback, and improvements: All recipients will be responsible for demonstrating functionality, championing early adoption, gathering feedback, and making one to two rounds of high-impact, feedback-based improvements.
Required Knowledge / Skills:
- Expertise with React Native and Hooks for Cross-Platform Android and iOS App development
References:
- sBTC Whitepaper
- Stacks Nakamoto Release Whitepaper
- sBTC project dashboard
- Clarinet Docs (reference for design system req’d for Typescript applications wrapped within a Rust application)
- TM Repo (code & documentation standard)
- Host a Web Server on Android
Critical Bounty Fee:
- Maximum Fee: $30,000
Reviewers / Advisors:
Igor Sylvester, Core Engineering Lead, Trust Machines Friedger Müffke Jude Nelson, Research Scientist, Stacks Foundation Jesse Wiley, Integration and Security Lead, Stacks Foundation Kenny Rogers, Developer Advocate, Stacks Foundation Will Corcoran, Grants Lead, Stacks Foundation
