What Is Moralis?

Moralis is a unified Web3 data API and development platform that provides developers with real-time access to blockchain data. Founded in 2021, it has grown to become the infrastructure backbone for over 100,000 DApps, ranging from small indie projects to enterprise-grade DeFi protocols. Moralis handles the heavy lifting of indexing, normalizing, and serving blockchain data through clean, well-documented REST APIs and SDKs.

The platform supports Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, Avalanche, Base, and several other EVM-compatible networks. It also offers non-EVM support for Solana and other chains. The core value proposition is simple: instead of operating complex node infrastructure and building custom indexers, developers can call a Moralis API endpoint and receive structured, human-readable data.

Moralis provides several key API groups: - Web3 API — General blockchain queries, block data, and transaction details

Token API — Token balances, transfers, price data, and metadata
NFT API — NFT ownership, metadata, transfers, and collection statistics
Wallet API — Portfolio tracking, net worth calculations, and transaction history
Streams API — Real-time webhooks for on-chain events
Auth API — Web3 authentication and user session management

Why Choose Moralis in 2026?

The Web3 infrastructure landscape has matured significantly, yet Moralis continues to lead for several compelling reasons.

Unified API surface. Rather than juggling multiple providers for different data types, Moralis offers a single API key that unlocks token data, NFT information, wallet portfolios, and real-time event streams. This reduces integration complexity and keeps your codebase cleaner.

Cross-chain compatibility. Moralis supports ten-plus EVM chains out of the box. Queries use the same endpoint structure regardless of which chain you target. Switching from Ethereum to Polygon requires changing a single chain parameter, not rewriting integration logic.

Real-time data delivery. The Streams API delivers webhooks within seconds of on-chain events confirming. For trading applications, portfolio trackers, and alert systems, this latency advantage is critical.

Enterprise-grade reliability. Moralis processes billions of API requests per month with a 99.9% uptime guarantee. Its infrastructure auto-scales to handle traffic spikes during NFT drops, token launches, and market volatility.

Rich SDK ecosystem. Official SDKs for JavaScript, Python, and Unity allow you to integrate Moralis in your preferred environment. React hooks and Next.js bindings further accelerate frontend development.

Setting Up Your Moralis Account

Before writing any code, you need a Moralis account and API key.

Step 1: Visit the Moralis admin console at admin.moralis.io and register a new account. You can use an email address or connect with a Web3 wallet.

Step 2: After logging in, create a new project from the dashboard. Give it a descriptive name such as ```defi-dashboardornft-tracker````.

Step 3: Navigate to the API Keys section and copy your default API key. Moralis uses a tiered pricing model. The free tier includes a generous number of API calls per month, which is sufficient for development and small production applications.

Step 4: Secure your API key using environment variables. Never commit API keys directly into your source code repository.

# .env
MORALIS_API_KEY=your_api_key_here

Load this variable in your application using dotenv or your runtime’s built-in environment variable support.

// server.js
require(dotenv).config();
const apiKey = process.env.MORALIS_API_KEY;
if (!apiKey) {
  throw new Error('MORALIS_API_KEY is not defined');
}

Installing the Moralis SDK

Moralis offers official SDKs for multiple programming languages and frameworks. Choose the one that matches your stack.

JavaScript / Node.js

npm install moralis

// Initialize Moralis in your Node.js application
const Moralis = require(moralis).default;

await Moralis.start({
  apiKey: process.env.MORALIS_API_KEY,
});

console.log('Moralis SDK initialized successfully');

Python

pip install moralis

# Initialize Moralis in Python
from moralis import evm_api
import os

api_key = os.environ.get(MORALIS_API_KEY)
if not api_key: raise ValueError("MORALIS_API_KEY environment variable is required")

print("Moralis Python SDK ready")

Unity

For Unity developers, Moralis provides a dedicated SDK package available through the Unity Package Manager. Import the package from the official Moralis GitHub repository, then initialize it in your game startup script.

// Unity C# initialization
using MoralisUnity;
using MoralisUnity.Web3Api.Client;

async void Start()
{
    MoralisClient moralis = new MoralisClient(
        hostUrl: "https://deep-index.moralis.io/api/v2",
        applicationId: "your_app_id"
    );
    await moralis.StartAsync();
    Debug.Log("Moralis Unity SDK initialized");
}

Fetching Token Data with the Token API

The Token API is one of the most frequently used components of Moralis. It provides endpoints for querying ERC-20 token balances, transfer history, price data, and metadata.

Get Token Price

Fetching the current price of any token is straightforward. Moralis aggregates price data from multiple decentralized exchanges and liquidity pools.

const priceResponse = await Moralis.EvmApi.token.getTokenPrice({
  address: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48,
  chain: 0x1, // Ethereum mainnet
});

console.log('Token Price:', priceResponse.result.usdPrice);
console.log('Price Change 24h:', priceResponse.result.usdPricePercentChange24h);

Get Wallet Token Balances

Retrieve all ERC-20 tokens held by a specific wallet address with a single API call.

const balances = await Moralis.EvmApi.token.getWalletTokenBalances({
  address: 0x1234567890123456789012345678901234567890,
  chain: 0x1,
});

balances.result.forEach((token) => {
  console.log(````${token.name}: ${token.balance} (${token.symbol})````);
});

Get Token Transfers

Track incoming and outgoing token transfers for a wallet or a specific token contract.

const transfers = await Moralis.EvmApi.token.getWalletTokenTransfers({
  address: 0x1234567890123456789012345678901234567890,
  chain: 0x1,
  limit: 10,
});

transfers.result.forEach((tx) => {
  console.log(````From: ${tx.fromAddress} To: ${tx.toAddress} Amount: ${tx.value}````);
});

Get Token Metadata

Retrieve detailed metadata for any ERC-20 token including name, symbol, decimals, and logo.

const metadata = await Moralis.EvmApi.token.getTokenMetadata({
  addresses: [
    0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48,
    0x6B175474E89094C44Da98b954EedeAC495271d0F,
  ],
  chain: 0x1,
});

metadata.result.forEach((token) => {
  console.log(````${token.name} (${token.symbol}) - ${token.decimals} decimals````);
});

Working with the NFT API

The NFT API provides comprehensive coverage for querying NFT ownership, metadata, transfers, and collection-level statistics. It supports both ERC-721 and ERC-1155 standards.

Get NFTs Owned by a Wallet

const nfts = await Moralis.EvmApi.nft.getWalletNFTs({
  address: 0x1234567890123456789012345678901234567890,
  chain: 0x1,
  limit: 20,
});

nfts.result.forEach((nft) => {
  console.log(````Collection: ${nft.name} Token ID: ${nft.tokenId}````);
  console.log(````Metadata: ${nft.metadata}````);
});

Get NFT Metadata by Token ID

const nftMetadata = await Moralis.EvmApi.nft.getNFTMetadata({
  address: 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D,
  tokenId: 1,
  chain: 0x1,
});

console.log('Name:', nftMetadata.result.name);
console.log('Image:', nftMetadata.result.metadata?.image);
console.log('Attributes:', nftMetadata.result.metadata?.attributes);

Get NFT Transfers for a Collection

const transfers = await Moralis.EvmApi.nft.getNFTContractTransfers({
  address: 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D,
  chain: 0x1,
  limit: 10,
});

transfers.result.forEach((tx) => {
  console.log(````Token ${tx.tokenId}: ${tx.fromAddress} -> ${tx.toAddress}````);
});

Python Example: Get Floor Price

from moralis import evm_api

params = {
    "address": "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D",
    "chain": "eth"
}

result = evm_api.nft.get_nft_floor_price(
    api_key=api_key,
    params=params,
)

print(f"Floor Price: {result[floor_price]} ETH")

Real-Time Webhooks with the Streams API

One of Moralis’s standout features is the Streams API, which enables real-time webhooks for on-chain events. Instead of polling for changes, your application receives push notifications when specific events occur.

Setting Up a Stream

const { EvmChain } = require('@moralisweb3/common-evm-utils');

const stream = {
  chains: [EvmChain.ETHEREUM, EvmChain.POLYGON],
