DIA is a cross-chain oracle provider that sources granular market data from diverse exchanges, including CEXs and DEXs. Its data sourcing is thorough, enabling unparalleled transparency and customizability for resilient price feeds for 20,000+ assets. Its versatile data processing and delivery ensures adaptability and reliability for any decentralized application.

How to access data

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 our oracle on Polygon. If you pass BTC/USD as the key, it will return the most recent price of BTC in USD with 8 decimal places (e.g. 9601458065403 is $96,014.58065403) 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 = 0x0000000000000000000000000000000000000000; // To be deployed

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