Apollo

The Oracle pallet provides functionality for setting up and maintaining an Apollo Oracle and submitting prices.

Overview

The Oracle pallet provides functions to:

  • Add assets and their respective data, and submit prices for those assets
  • Set a signer to ensure proper calls for transactional functions
  • Manage stake associated with signer for operating an Oracle
  • Adjust reward configuration for Oracles

Workflows

Oracle Configuration

Setting up an Oracle for operation requires three steps:

  1. add_asset_and_info to configure the asset to get prices for
  2. set_signer to uniquely identify the operator of an Oracle requires a call to add_stake to run it.
  3. adjust_rewards to configure rewards for Oracles

After successfully setting up the Oracle, you can submit prices using the submit_price extrinsic. For more information refer to the Oracle Set-Up Guide

Stake Management

The Oracle pallet provides basic functionalities to manage the stake needed to run an Oracle:

  • add_stake to add more stake
  • remove_stake claim to remove stake immediately
  • reclaim_stake reclaim stake after proper time has passed
