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 0xf93205bf6f61bce30eab03584d7ba17ef874ef68.

You can query for assets by calling the read function getValue() with parameters such as “rsETH/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: 0x002f6efb18e333465a13928f448113b16d4ef6ee

Markets

You can view the markets included for each feed by pressing on a link to DIA App in the deployed assets list:

  1. Ethereum-0xA1290d69c65A6Fe4DF752f95823fae25cB99e5A7
  2. Ethereum-0xCd5fE23C85820F7B72D0926FC9b05b43E359b7ee

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.
