CDR #087 Gravita Protocol | Token Price Feed [Arbitrum]


Protocol: Gravita Protocol


Integration: GRAI price feed

Use case: Lending and Borrowing

Blockchain: Arbitrum



The following assets will be included in the Oracle:


  • Moving Average Price with Interquartile Range (MAIR) will be used to calculate the price for the asset. Learn more about it here.
  • 0.5% 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


Select if the feed should be delivered on-chain via oracle and if so, which network:

  • Delivery method: Oracle on Arbitrum
  • Testnet required: No

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


The oracle is deployed and can be accessed here.

You can query for assets by calling the read function getValue() with parameters such as “GRAI/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.


Each deployed oracle contract 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: 0xd0aeb2c8a4e625cae813c567d3a7f665da96ad49


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

  1. Ethereum-0x15f74458aE0bFdAA1a96CA1aa779D715Cc1Eefe4
  2. Arbitrum-0x894134a25a5faC1c2C26F1d8fBf05111a3CB9487

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.

Hi, we really appreciate your product. We would like to have a GRAI oracle also deployed on Linea with the same parameters.
