Methodology

  • Moving Average Price with Interquartile Range (MAIR) will be used to calculate the price for the asset. Learn more about it here.

  • 1% deviation threshold for updates trigger will be applied

  • 120s trades aggregation window size will be applied

  • The feed will be updated every 24h period if there are no deviation based updates

DELIVERY INFORMATION

Delivery Method Oracle on Avalanche
Is testnet deployment required? No
2

Thank you for requesting a data feed via DIA CDR. We confirm the CDR specifications were requested correctly. Find the oracle information below:

Oracle

The oracle is deployed and can be accessed here.

You can query for assets by calling the read function getValue() with parameters such as “BTC/USD”. It will return two values:

  1. The price of the asset queried with 8 decimals
  2. The unix timestamp of the last update

You can see Solidity and Vyper code integration examples here or use a dedicated DIA oracles integration library described in detail here.

Funding

Each deployed oracle has a separate gas wallet which is the only entity allowed to update oracle values based on selected parameters. To find out more information on how it works, visit the following link.

Please make sure to top up the gas wallet, as we only put in some gas to deploy and start the oracle.

Gas Wallet address: 0x349b8cD4A65e1a306cBa29f47722cD2729a9734E

Note: DIA uses Blockchain-Address querying formatting to ensure asset selection precision (token symbols might duplicate)

You can also query current asset prices and find other market information on the asset by using the DIA API as described here.
