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

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