FCL Functionality Implementation

[maggo]

This issue tracks FCL functionality as seen in the FCL API Documentation and its implementation in use-flow.

The issue will be updated as new abstractions are being added, the completion of all items concludes Milestone 1.

Wallet Interactions

• authentication – Wallet authentication and unauthentication
• currentUser – Information and helper functions of the connected user
• discovery – Functionality to discover compatible wallets (eg. for custom login pages)

On-Chain Interactions

Builder functions (send, decode, getAccount, etc) will be left out in the first release for ease-of-use. The library will provide a useFCL hook to access the native fcl object and its functionality.

• query – Read-only access of on-chain data #3
• mutate – Write-access transactions that can mutate on-chain data
• AppUtils – Utility functions to verify signed messages and account ownership

Pre-built Interactions

• account – Information about a Flow on-chain account
• block – Information about a Flow block
• tx – Information about a Flow transaction, including polling for completion
• events – Functionality to subscribe to Flow events
