CrossFi API Quickstart
Get started building on CrossFi and using the JSON-RPC API
To use the CrossFi API you’ll need to create a free Alchemy account first!
Introduction
CrossFi is a blockchain platform built to enable seamless cross-chain asset transfers and decentralized finance (DeFi) applications. With a focus on interoperability, security, and scalability, CrossFi provides developers and users with a powerful ecosystem for deploying decentralized applications (dApps) that can operate across multiple blockchain networks.
What is the CrossFi API?
The CrossFi API facilitates interaction with the CrossFi network through a collection of JSON-RPC methods. Given its developer-friendly design, those familiar with Ethereum’s JSON-RPC APIs will find working with CrossFi intuitive and straightforward.
Getting Started Instructions
1. Choose a Package Manager (npm or yarn)
Your first step involves selecting a package manager, which will be crucial for managing your project’s dependencies. The choice between npm
and yarn
depends on your personal preference or project requirements.
2. Set Up Your Project
To kickstart your project, open your terminal and execute the following commands:
This creates a new directory named crossfi-api-quickstart
and initializes a Node.js project within it.
3. Make Your First Request
For making API requests, we’ll use Axios, a widely-used HTTP client. Install Axios with the following command:
Next, create an index.js
file in your project directory. Paste the following code to send a request to the CrossFi network:
Remember to replace yourAPIKey
with your actual Alchemy API key that you can get from your Alchemy dashboard.
4. Run Your Script
To execute your script and make a request to the CrossFi network, run:
You should see the latest block information from CrossFi’s blockchain outputted to your console:
Next Steps
Well done! You’ve just made your first request to the CrossFi API. With this foundation, you can dive deeper into the array of JSON-RPC methods available on CrossFi and start building your dApps on it!
