DIA

DIA is a cross-chain, trustless oracle network delivering verifiable price feeds for Aurora. DIA sources raw trade data directly from primary markets and computes it onchain, ensuring complete transparency and data integrity.

Key Features​

  • Complete verifiability from source to destination smart contract.
  • Direct data sourcing from 100+ primary markets eliminating intermediary risk.
  • Support for 20,000+ assets across all major asset classes.
  • Custom oracle configuration with tailored sources and methodologies.

How to Access Price Feeds​

Call the getValue(string memory key) function on the oracle contract with the Query Symbol (e.g., BTC/USD). The function returns the asset price with 8 decimal precision and the timestamp of the last update. DIA maintains the supported assets here. We'll use this oracle address on Aurora testnet: 0xf4e9C0697c6B35fbDe5a17DB93196Afd7aDFe84f.

pragma solidity ^0.8.13;

interface IDIAOracleV2 {
    function getValue(string memory) external view returns (uint128, uint128);
}

contract DIAOracleV2Consumer{
    /**
     * @notice The DIA oracle to read from.
     * Network: Aurora Testnet
     * Address: 0xf4e9C0697c6B35fbDe5a17DB93196Afd7aDFe84f
     */
    address constant ORACLE = 0xf4e9C0697c6B35fbDe5a17DB93196Afd7aDFe84f;

    function getPrice(string memory key)
    external
    view
    returns (
        uint128 latestPrice,
        uint128 timestampOfLatestPrice
    ) {
        (latestPrice, timestampOfLatestPrice) =
                 IDIAOracleV2(ORACLE).getValue(key);
    }
}
