Flow Providers: Non-custodial wallets

[srinjoyc]

👋   If you are interested in working on this issue, please check out the Getting Started guide on HackerEarth!

⚠️   This is a special project outside of the existing format of FLIP Fest and requires an application to receive a custom grant structure to work on it.

Description (Problem Statement)

Flow is looking for wallet providers to join the ecosystem.

Please review our RFP (Request for Proposal) document to understand the current ecosystem and its gaps new wallets should ideally fill.

Experience Required

• Previous or current experience on blockchain wallets and their use in production environments
• Team capacity to build, support and maintain support on Flow into the long term
• Strong design, technical, and legal experience within the team

Milestone Requirements

A custom structure will be set for successful applications on a case-by-case basis.

Application

Hi guys, our team would like to add flow support in our non-custodial smart wallet solution of UniPass.
Team name: Lay2
Team repo: github.com/lay2dev

[srinjoyc]

For the ZayCodes Team, here are the milestones:

Milestone 1
Create an architectural diagram along with any relevant documentation to describe how custody, signatures, UI, and any other services need to interact in order to meet the requirements of the other milestones.

Milestone 2
Meet any of the FCL service specs for authorization and authentication (IFRAME, TAB, POP, etc.)

1. Create an authentication endpoint and view

   • Collect the user information and authenticate them against the wallet's database to provide back the authentication response.
   • Must support both existing and new users in the same user flow

2. Create an authorization endpoint and view

   • Show relevant transaction information

3. Create a pre-authorization endpoint

   • Replace the payer role

Milestone 3
Demonstrate storage of private keys in a non-custodial manner (client-side) using secure web crypto apis or otherwise. At this milestone, there should be an end to end flow for both authentication and authorization that can be demoed in some environment.

Milestone 4
Optimize the user experience and attempted to solve the problems listed in the Flow Wallet RFP. Provide documentation for both developers and end-users.
