Lion Swap Documentation - Developer Resources

Getting Started

Welcome to the Lion Swap API documentation. Our API enables you to integrate cross-chain swaps into your application.

Installation

                        npm install @lionswap/sdk
                        # or
                        yarn add @lionswap/sdk

Authentication

All API requests require authentication using API keys. You can generate API keys from your dashboard.

const LionSwap = require('@lionswap/sdk');
const client = new LionSwap({
    apiKey: 'your-api-key',
    environment: 'mainnet' // or 'testnet'
});

API Reference

Endpoints

Endpoint	Description
/v1/quote	Get quote for token swap
/v1/swap	Execute token swap
/v1/status	Check swap status

SDK Integration

Our SDK provides a simple way to interact with the Lion Swap protocol.

// Initialize the SDK
const swap = await client.createSwap({
    fromToken: 'ETH',
    toToken: 'USDC',
    amount: '1.0',
    fromChain: 'ethereum',
    toChain: 'polygon'
});

WebSocket API

Real-time updates for swap status and price feeds.

const ws = new LionSwap.WebSocket('wss://api.lionswap.com/ws');
ws.subscribe('PRICE_FEED', {
    pairs: ['ETH/USDC', 'BTC/USDT']
});

Code Examples

Simple Swap Example

// Complete swap example
const swap = await client.createSwap({
    fromToken: 'ETH',
    toToken: 'USDC',
    amount: '1.0',
    fromChain: 'ethereum',
    toChain: 'polygon'
});

// Wait for confirmation
const receipt = await swap.wait();
console.log('Swap completed:', receipt);
