Explore ways to setup a client library for kuber-hydra

[mesudip]

Scope of this Ticket:

• Determine external library dependencies required.
• Determine changes required in kuber-client and libcardano pacakages.
• Determine how to integrate with both browser and serverside NodeJs in single package

[reeshavacharya]

To Do:

• generate private key from wallet seed phrases and use it to run the hydra node.
  - This is needed for the browser wallet signature to be validated in hydra

Changes in kuber-Client

• Add the hydra comnand functions (init, abort, close, etc.)
• Add function to commit and de-commit UTxOs
• Add function to sign and submit hydra transaction

Changes in libcardano

• TBD

External Library Dependency

• This will be discovered as the project is being built

[mesudip]

Update

• Added hydra lifecycle endpoints in client
• WIP hydra wallet

[mesudip]

Update

What has been done in Libcardano

• [x] created a module 'libcardano-wallet' in the libcardano repo
• [x] 2 interfaces. QueryAPIProvider and SubmitAPIProvider
• [x] a CIP30 wallet class with wallet features. The constructor of this class requires query api provider and submit api provider instances
• [x] PR: https://github.com/cardanoapi/libcardano/pull/15

What has been done in kuber-client-js

• [x] class KuberHydraService implements SubmitAPIProvider, QueryAPIProvider (makes calls to api provided by kuber-hydra-server)
• [x] class KuberNodeService implements SubmitAPIProvider, QueryAPIProvider (makes calls to api provided by kuber-server)
• [x] Simple implementation of hydra wallet (CIP30Wallet class imported from libcardano)

  •   export class HydraWallet extends CIP30Wallet {
          constructor(hydraService: KuberHydraService) {
              super(hydraService, hydraService);
          }
      }  
    

• [x] WIP test and setup instructions
