As discussed in this Polkadot forum thread and elsewhere, it would be useful for the staking pallet to expose a few runtime APIs that can be called through the state_call RPC to help UIs and clients to query dynamic onchain data that is required for showing stats in UIs and help building extrinsic parameters.

Examples of RPC methods:

  • StakingApi_nominationsQuota: Returns the number of nominations quota per bonded balance, to help UIs calculating the max nominations for the account (implemented in this PR);
  • NominationPoolsApi_balance_to_point
  • NominationPoolsApi_points_to_balance
