To set up the application, follow the instructions below.
- Create a package.json file as below
npm init -y2. Install moralis and @moralisweb3/common-sol-utilsdependency as follows
npm i moralis @moralisweb3/common-sol-utils3. Your package.json should contain the following
{
"name": "moralis-solana-balance",
"version": "1.0.0",
"description": "",
"main": "server.js",
"scripts": {
"start": "node server.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"@moralisweb3/common-sol-utils": "^2.7.4",
"dotenv": "^16.0.3",
"express": "^4.18.2",
"moralis": "^2.7.4"
}
}4. Create a .env file which contains the Moralis API_KEY
API_KEY = “Your Moralis API Key”5. Start the server in server.js
require('dotenv').config();
const express = require('express');
const app = express();
app.use(express.json());
app.listen(8080, async () => {
console.log('server started');
});6. Start Moralis in server.js
require('dotenv').config();
const express = require('express');
const Moralis = require('moralis').default;
const app = express();
const { API_KEY } = process.env;
app.use(express.json())
async function startMoralis() {
try{
await Moralis.start({
apiKey: API_KEY,
});
}catch(err) {
console.log(err);
}
}
app.listen(8080, async () => {
startMoralis();
console.log('server started');
})7. Add a GET endpoint /sol-balance to get the native solana balance
require('dotenv').config();
const express = require('express');
const Moralis = require('moralis').default;
const { SolNetwork } = require('@moralisweb3/common-sol-utils');
const app = express();
const { API_KEY } = process.env;
app.use(express.json())
async function startMoralis() {
try{
await Moralis.start({
apiKey: API_KEY,
});
}catch(err) {
console.log(err);
}
}
app.get('/sol-balance', async (req, res) => {
const network = SolNetwork.MAINNET;
const { address } = req.body;
try{
const response = await Moralis.SolApi.account.getBalance({
address,
network,
});
res.status(200).send(response.toJSON());
}catch(err) {
console.log(err);
}
})
app.listen(8080, async () => {
startMoralis();
console.log('server started');
})8. Test the endpoint using Postman
The test result is given below. Give the wallet address in req.body
Summary
Up to this point, we have talked about utilizing the Moralis Solana API and NodeJs to obtain the native balance of a solana wallet. Open a Moralis account and play around with their APIs.
