Alchemy RPC

Overview

Alchemy provides scalable RPC infrastructure and developer tooling for interacting with blockchain networks.

On Pharos, Alchemy can be used to access reliable RPC endpoints for both Pacific Mainnet and Atlantic Testnet, making it suitable for application development and production use.

Getting Started with Alchemy

To use Alchemy with Pharos, you’ll need to create an Alchemy account and generate an API key.

Here are some prerequisites before you start interacting:

1. Sign up or log in to Alchemy
2. Create a new app
3. Select the Pharos network
4. Generate your API key

Once done, the API key will let you interact with the Pharos network through a set of JSON-RPC methods. Follow the guide below to start interacting with Pharos.

Step 1. Choose a package manager (npm or yarn)

Choose between npm and yarn based on your preference or project requirements.

npm

# Begin with npm by following the npm documentation
# https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

yarn

Step 2. Set up your project

Run the following commands to create and initialize your project:

npm

$ mkdir pharos-api-quickstart
$ cd pharos-api-quickstart
$ npm init --yes

yarn

This creates a new directory named pharos-api-quickstart and initializes a Node.js project within it.

Step 3. Make your first request

Install Axios, a popular HTTP client, to make API requests:

npm

$ npm install axios

yarn

Create an index.js file in your project directory and paste the following code:

const axios = require('axios');
 
const url = 'https://pharos-mainnet.g.alchemy.com/v2/your-api-key';
 
const payload = {
  jsonrpc: '2.0',
  id: 1,
  method: 'eth_blockNumber',
  params: []

Replace your-api-key with your actual Alchemy API key from the Alchemy Dashboard

Step 4. Run your script

Run your script to make a request to the network:

$ node index.js

You should see the latest block information from Pharos's network outputted to your console:

$ Latest Block: 0x...

Next Steps

You've made your first request to the Pharos using Alchemy API. You can now explore the various JSON-RPC methods available on Pharos and start building your dApps.
