Moralis

Moralis is a Web3 development platform that radically simplifies the creation of decentralized applications (dApps) by providing ready-to-use backend infrastructure. It enables developers to focus on business logic rather than the technical complexity of blockchain infrastructure. Moralis offers unified APIs to query on-chain data, manage Web3 authentication, and interact with multiple blockchains through a consistent interface.

Fundamentals

• Managed backend infrastructure eliminating the need to configure blockchain nodes or custom indexers
• Multi-chain APIs supporting Ethereum, Polygon, BSC, Avalanche, Fantom, Arbitrum, and over 20 blockchains
• JavaScript/TypeScript, Python, and Unity SDKs for rapid integration across different development environments
• Real-time synchronization system enabling listening and reacting to blockchain events instantly

Benefits

• 87% reduction in development time according to internal benchmarks, going from several months to a few weeks
• Reduced infrastructure costs by avoiding dedicated blockchain node maintenance (average savings of $5,000-10,000/month)
• Normalized APIs offering a consistent experience regardless of the target blockchain
• Integrated Web3 authentication with native support for MetaMask, WalletConnect, and other popular wallets
• Comprehensive documentation and active community with over 200,000 developers for rapid support

Practical Example

Here's how to retrieve NFT transaction history for an address with Moralis in just a few lines:

import Moralis from 'moralis';
import { EvmChain } from '@moralisweb3/common-evm-utils';

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

// Retrieve NFT transfers for an address
const response = await Moralis.EvmApi.nft.getWalletNFTTransfers({
  chain: EvmChain.ETHEREUM,
  address: '0x1234567890123456789012345678901234567890',
});

// Display results
console.log('Total transfers:', response.result.length);
response.result.forEach((transfer) => {
  console.log(`NFT: ${transfer.name}`);
  console.log(`From: ${transfer.fromAddress}`);
  console.log(`To: ${transfer.toAddress}`);
  console.log(`Date: ${transfer.blockTimestamp}`);
  console.log('---');
});

Implementation

1. Create a free account on moralis.io and obtain an API key from the admin dashboard
2. Install the Moralis SDK via npm or yarn: npm install moralis @moralisweb3/common-evm-utils
3. Initialize Moralis in your application with the API key using Moralis.start()
4. Choose appropriate APIs based on your needs (NFT API, Token API, Wallet API, Transaction API, etc.)
5. Implement Web3 authentication if needed with Moralis.Auth to manage wallet connections
6. Configure Streams API webhooks to receive real-time notifications on blockchain events
7. Test with the free plan (40,000 requests/month) before upgrading to paid plans based on volume
