NChainlink

NChainlink a library made for Nethereum to help work with chainlink smart contract

How to use NChainlink

Basic example

using System;
using Nethereum.Web3;
using NChainlink;
using System.Threading.Tasks;

//Ethereum endpoint URL.
var web3 = new Web3("https://mainnet.infura.io/v3/<key>");

//Pass web3 to chainlink to access Ethereum
var chainlink = new Chainlink(web3);

//Address of price feed oracle.
var pricefeed = chainlink.Pricefeed("0xDC530D9457755926550b59e8ECcdaE7624181557");

//Description, this address contract will return Token pair name.
var description = await pricefeed.GetDescriptionAsync();

//get all information about the last data.
var lastRoundData = await pricefeed.GetLatestRoundDataAsync();

//Show the last price.
Console.WriteLine($"Latest Price { lastRoundData.Answer} of { description }");

Comple example with domain Ens and price in Eth

using System;
using Nethereum.Web3;
using Nethereum.ENS;
using NChainlink;
using System.Threading.Tasks;

 //Ethereum endpoint URL.
var web3 = new Web3("https://mainnet.infura.io/v3/97c8a7fd43b149d9a7b31ffd4894dfd9");

//Create a Ens service; 
var ensService = new ENSService(web3);

//Turn an Ens URL into contract address.
var address = await ensService.ResolveAddressAsync("link-eth.data.eth");

//Pass web3 to chainlink to access Ethereum
var chainlink = new Chainlink(web3);

//Address of price feed oracle.
var pricefeed = chainlink.Pricefeed(address);

//Description, this address contract will return Token pair name.
var description = await pricefeed.GetDescriptionAsync();

//get all information about the last data.
var lastRoundData = await pricefeed.GetLatestRoundDataAsync();

//Convert last price in wai to eth
var LastPriceInEth = Web3.Convert.FromWei(lastRoundData.Answer);
//Convert unix time to datetime
var LastUpdateDateTime = DateTimeOffset.FromUnixTimeSeconds((long)lastRoundData.UpdatedAt);

//Show latest name,price and time
Console.WriteLine($"Description: { description }\nPrice: {LastPriceInEth}\nTime: { LastUpdateDateTime}");

Goals

• Read pricefeed contract
• build a website for the documentation
• Add support to chainlink market
• Read VRF contract
