Witnet Price Feeds on Conflux Network

Witnet Foundation operates a series of public price feeds in cooperation with Conflux Network both for showcasing the capabilities of the Witnet oracle,and as a public service for the broader Conflux community.

All Witnet price feeds comply with the ERC-2362 interface: a standard interface for price feeds, cooperatively envisioned by Witnet, Tellor, Band, Razor and other oracles.

Therefore, using any of these price feeds is as simple as:

pragma solidity >=0.5.0 <0.9.0;

import "ado-contracts/contracts/interfaces/IERC2362.sol";

contract MyContract {

    function readFromPriceFeed() external view returns(int256) {
        IERC2362 priceFeed = IERC2362("<address of the price feed>");
        bytes32 assetID = bytes32(hex("<asset ID>"));
        int256 value = priceFeed.valueFor(assetID);

        return value;
    }

}

The available asset IDs for each of the public price feeds are also listed down below. A full list of asset IDs can be found in ADOIP-0010.

Floats and decimal digits

As Solidity does not currently support float types, all prices are provided as int256, with a specific number of decimal digits. For example, if the BTC/USD price is 31371.21, the BTC/USD contract below will give31371210 because it is using 3 decimal digits.
