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:
Testnet
Mainnet

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 addresses:
Testnet: 0xE59DD28E89e1088f5b7be1335885EC501b562B58
Mainnet: 0x0E5c034130E60EA37e2F41E3dB8B7D90362C902C

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