Multichain support - design research

[theblockstalk]

we want to allow Tonomy ID to support transactions signing on multiple blockchain networks (e.g. sign a Hedera trx). We will leveraged the existing Tonomy ID and Tonomy Developer Console to allow this to happen but need to design screens on both platforms to facilitate this.

In this task, we will research existing multi-chain wallets and how they are facilitated by the network apps, and create a set of user stories or wireframes to define these flows in Tonomy.

This is the general idea to support:

• in the Tonomy Developer Consol, developers will be able to log in and create an app where they can specify What networks they would like to sign transactions on (e.g. Hedera). Creating an app designs exist, choosing a network does not. See https://www.figma.com/file/7Qg0z3dTuxVtijUdikgEbP/Tonomy-Developer-Console?type=design&node-id=1167-197&mode=design&t=a9QSlS7nR2Zg68AG-4
• after a user signs into this created app, during the SSO flow that has requested a key for a specific network e.g. Hedera, Then they will use the app and when the app developer once the user designer transaction, a screen will be displayed on the users Tonomy ID app on their phone, with a consent screen To ask if they want to sign the transaction and what network they're signing the transaction. This is already partially designed, assuming the transaction is on the Pangea blockchain, here https://www.figma.com/file/cvV48t0f7O2znT6QBxK0Zj/Tonomy-ID?type=design&node-id=772-7949&mode=design&t=q9XqssHCPHtaA1LV-4
• in Tonomy ID: the user should be able to see what networks they are on, and what their account name is on each network

Acceptance criteria

• [x] Research existing multi-chain wallets
• [ ] One or both of the following (Whatever quickest)
  • Created of wireframes that show the changes in the flow in Tonomy ID
  • great a set of user stories that describe the new behaviours in Tonomy ID
