JKorf.Lighter.Net 1.5.1

Lighter.Net

Lighter.Net is a client library for accessing the Lighter DEX REST and Websocket API.

Features

• Response data is mapped to descriptive models
• Input parameters and response values are mapped to discriptive enum values where possible
• High performance
• Automatic websocket (re)connection management
• Client side rate limiting
• Client side order book implementation
• Support for managing different accounts
• Extensive logging
• Support for different environments
• Easy integration with other exchange clients based on the CryptoExchange.Net base library
• Native AOT support

Documentation

The Lighter.Net documentation is the main resource for installing, configuring, and using the library.

Supported Frameworks

The library is targeting both .NET Standard 2.0 and .NET Standard 2.1 for optimal compatibility, as well as the latest dotnet versions to use the latest framework features.

Install the library

NuGet

dotnet add package JKorf.Lighter.Net

GitHub packages

Lighter.Net is available on GitHub packages. You'll need to add https://nuget.pkg.github.com/JKorf/index.json as a NuGet package source.

Download release

The NuGet package files are added along side the source with the latest GitHub release which can found here.

How to use

Basic request:

// Get the ETH/USDC ticker via rest request
var restClient = new LighterRestClient();
var tickerResult = await restClient.ExchangeApi.ExchangeData.GetSymbolDetailsAsync("ETH/USDC");
if (!tickerResult.Success)
{
    Console.WriteLine($"Error: {tickerResult.Error}");
    return;
}

var lastPrice = tickerResult.Data.SpotSymbols[0].LastPrice;

Place order:

var restClient = new LighterRestClient(opts => {
    opts.ApiCredentials = new LighterCredentials(EthKey.FromPrivateKey("KEY"), 123, 5, "APISECRET");
});

// Place Limit order to go 0.1 long for ETH at 2000
var orderResult = await restClient.ExchangeApi.Trading.PlaceOrderAsync(
    "ETH",
    OrderSide.Buy,
    OrderType.Limit,
    0.1m,
    2000m,
    timeInForce: TimeInForce.GoodTillTime
    );

WebSocket subscription:

// Subscribe to ETH/USDC ticker updates via the websocket API
var socketClient = new LighterSocketClient();
var tickerSubscriptionResult = socketClient.ExchangeApi.ExchangeData.SubscribeToSpotTickerUpdatesAsync("ETH/USDC", (update) =>
{
    var lastPrice = update.Data.Ticker.LastPrice;
});

For more examples and explanations, continue with the Lighter.Net documentation or browse the compilable repository examples.

NOTE
Lighter.Net uses the Integrator Code mechanism for Lighter, which means that an additional 1bps / 0.01% fee is charged on top of orders placed with the library to fund development. This is entirely optional and can be disabled in the client options by setting IntegratorFeePercentage to 0 or null in the client options.

AI / LLM documentation

Lighter.Net includes AI-oriented documentation and examples for code generation tools:

See cryptoexchange-skills-hub for installable skills.

Shared / unified API

The CryptoExchange.Net Shared APIs provide exchange-agnostic, unified interfaces for common operations such as retrieving tickers, order books and balances, placing orders, and subscribing to market updates.

This allows the same application code to work with different exchange libraries. The supported Lighter API surfaces expose their shared functionality through a SharedClient property. Because support differs between exchanges and API surfaces, call Discover() to inspect the available trading modes, environments, endpoints, and subscriptions at runtime.

Supported shared interfaces

Discover supported functionality

var sharedClient = new LighterRestClient().ExchangeApi.SharedClient;
var clientInfo = sharedClient.Discover();

Console.WriteLine(clientInfo);

Example

using Lighter.Net.Clients;
using CryptoExchange.Net.SharedApis;

var sharedClient = new LighterRestClient().ExchangeApi.SharedClient;
ISpotTickerRestClient tickerClient = sharedClient;

var symbol = new SharedSymbol(TradingMode.Spot, "ETH", "USDT");
var result = await tickerClient.GetSpotTickerAsync(
    new GetTickerRequest(symbol));

if (!result.Success)
{
    Console.WriteLine(result.Error);
    return;
}

Console.WriteLine(result.Data.LastPrice);

The request and response models belong to CryptoExchange.Net.SharedApis, so the same pattern can be used with another exchange's SharedClient.

CryptoExchange.Net

Lighter.Net is based on the CryptoExchange.Net base library. Other exchange API implementations based on the CryptoExchange.Net base library are available and follow the same logic.

CryptoExchange.Net also provides shared access to different exchange APIs.
