Flow Providers: Non-custodial wallets - Milestone 1

Description

This PR is for issue #28.

• We have complete the design of the wallet.
• Brief introduction of the features we'll cover and how we'll achieve them.
• Details about the architecture of key management and user flow.
• Prospects to the future when we can implement the full version of UniPass on Flow to present a keyless experience for users in an non-custodial way.

Submission Links & Documents

• Document link: https://lay2.notion.site/UniPass-Flow-Wallet-Design-4b165a80e5ba4e64b7051461fab3a0cf.

Requirements Check

• Have have you met the milestone requirements?
  • Yes
• Have you included tests (if applicable)?
  • No tests for this milestone
• Have you met the contribution guidelines of the repos you have submitted code to (if applicable)?
  • No code for this milestone

Other Details

• Is there anything specific you'd like the PoC to know or review for?

  • UniPass has one of the best account abstraction design, yet it requires RSA signature verification ability from the Layer1 to make it possible.
  • For now we have to use mnemonics as the backup method, which we think is too much for ordinary users.
  • We would like to bring an Internet experience also to Flow users, so maybe we can discuss about this feature after we complete this request.
  • Introduction ariticle about UniPass: https://medium.com/unipass/unipass-your-universal-crypto-identity-in-metaverse-b8b932f9313f

• Are there other references, documentation, or relevant artifices to mention for this PR (ie. external links to justify design decisions, etc.)?

  • UniPass adheres to a pure web format, so as to achieve maximum compatibility and cross-platform ability, and significantly reduce user cost with instant access through links.
  • We are not compromising on security because of convenience, because we manage the keys through built-in managers of the browsers(SubtleCrypto) and even the devices(Webauthn).
