Action Items

• O3: Remove friction from building dApps

  • KR1: FT / NFT information is easily available for the developers

    • Complete NFT events support for Indexer for Explorer (@telezhnaya)

  • KR3: Release near-jsonrpc-client-rs

    • Drop the old near-jsonrpc-client from nearcore (@miraclx)
      • Incremental developments here, but still inconclusive. Working with the new near-jsonrpc-client-rs in the context of which the old client was used is slightly tricky due to being properly typed but it's coming along good.
    • Migrate near-cli-rs to the new near-jsonrpc-client to take advantage of better strict typing as well as the new authorization support (@miraclx)
    • Fuzz testing RPC (@miraclx)
