Oracles

Chronicle (opens in a new tab)

The first Oracle on Ethereum, Chronicle Protocol's decentralized Oracle network was originally built within MakerDAO for the development of DAI and is now available to builders on Superseed. For more info explore Chronicle's documentation: https://docs.chroniclelabs.org/ (opens in a new tab).

How to Access Data

Accessing the oracle on-chain (Solidity)

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 (opens in a new tab) or the interface (opens in a new tab).

Below is an example of a contract consuming data from our oracle on Sepolia testnet. If you pass WETH/USD as the key, it will return the most recent price of WETH in USD with 8 decimal places (e.g. 177101990135 is $1,771.01990135) 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 DIAOracleSample {
 
    address immutable ORACLE = 0x6f021bF081840F96bdd90fd756b700072C7E68A5;
 
    function getPrice(string memory key)
    external
    view
    returns (
        uint128 latestPrice,
        uint128 timestampOflatestPrice
    ) {
        (latestPrice, timestampOflatestPrice) =
                 IDIAOracleV2(ORACLE).getValue(key);
    }
}

See the full example here (opens in a new tab).

Adapter contracts

To consume price data from our oracle, you can use the adapter smart contract located above 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 (opens in a new tab).
