Swagger API Integration guide can be found here:

https://gasyard.github.io/gasyard-sdk-documentation/

Installation

Install the Gasyard SDK via npm:

npm install gasyard-sdk

Quick Start

const { GasyardSDK } = require('gasyard-sdk');

// Initialize the SDK
const sdk = new GasyardSDK({
  apiKey: 'your-api-key' // Use 'trial' for testing
});

Supported Networks

The SDK supports bridging across the following networks:

Important Notes:

• Use Gasyard Chain ID in all SDK method calls (not Network Chain ID)
• Native tokens always use address 0x0000000000000000000000000000000000000000
• Token addresses are listed in the same order as the supported tokens column

Core Methods

1. Get Network Configuration

Retrieve all supported networks and their configurations:

async function getNetworkConfig() {
  try {
    const config = await sdk.getConfig();
    console.log('Supported networks:', config);
    return config;
  } catch (error) {
    console.error('Error fetching config:', error);
  }
}

2. Get Bridge Quote
