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

How to Access Data

​
getValue Method

To consume price data, you’ll need to invoke the getValue method on the oracle contract which you can access through the DIA Oracle library or the interface. Below is an example of a contract consuming data from the oracle on Sei Mainnet. If you pass USDr/USD as the key, it will return the most recent price of USDr in USD with 18 decimal places (e.g. 994895326000000000 is $0.994895326000000000) along with the Unix timestamp of the last price update. 
pragma solidity ^0.8.13;

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

contract DIAOracleV2Consumer{

    address immutable ORACLE = 0x32fFe7A0A14F95373bd720Be210AA6C2E94eFCEA;

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

​
Adapter contracts

To consume price data from our oracle, you can use the adapter smart contract located at the adapter address for each asset. This will allow you to access the same methods on the AggregatorV3Interface such as getRoundData & latestRoundData. You can learn more here. This is a sample contract for consuming the USDr/USD price feed: 
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.13;

interface DiaAssetSpecificCallingConvention {
    function latestRoundData() external view returns (
        uint80 roundId,
        int256 answer,
        uint256 startedAt,
        uint256 updatedAt,
        uint80 answeredInRound
    );
}

contract DIAOracleSample {
    address usdrAdapter = 0x42D1059364DF819Ae90bD86Dc2E80e7C28D1beD7;

    function getUSDrLatestPrice() external view returns (
        uint128 latestPrice,
        uint128 timestampOfLatestPrice
    ) {
        // Call the Chainlink adapter's latestRoundData function
        (, int256 answer, , uint256 updatedAt, ) =
            DiaAssetSpecificCallingConvention(usdrAdapter).latestRoundData();

        latestPrice = uint128(uint256(answer));
        timestampOfLatestPrice = uint128(updatedAt);

        return (latestPrice, timestampOfLatestPrice);
    }
}
