How to get all the NFTs owned by an address cross chain

Prerequisites

Before getting started, make sure you have the following ready:

• Node v.14+ or Python
• NPM/Yarn or Pip

Step 1: Setup Moralis

First register your Moralis account and get your Moralis API Key.

Once you have your Moralis API Key, install the Moralis SDK in your project.

npm

npm install moralis @moralisweb3/common-evm-utils

yarn

yarn add moralis @moralisweb3/common-evm-utils

pnpm

pnpm add moralis @moralisweb3/common-evm-utils

pip

pip install moralis

Step 2: Get All NFTs Owned By An Address

In order to get all the NFTs owned by an address, Moralis provides you with a getWalletNFTs endpoint to do so.

Here you'll need two parameters: address and chain (add as many blockchains as you want to the allNFTs array).

Once you've obtained both the address and chain, you can copy the following code:

index.js (JavaScript)

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const allNFTs = [];

  const address = "0xd8da6bf26964af9d7eed9e03e53415d37aa96045";

  const chains = [EvmChain.ETHEREUM, EvmChain.BSC, EvmChain.POLYGON];

  for (const chain of chains) {
    const response = await Moralis.EvmApi.nft.getWalletNFTs({
      address,
      chain,
    });

    allNFTs.push(response);
  }

  console.log(allNFTs);
};

runApp();

index.ts (TypeScript)

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

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const allNFTs = [];

  const address = "0xd8da6bf26964af9d7eed9e03e53415d37aa96045";

  const chains = [EvmChain.ETHEREUM, EvmChain.BSC, EvmChain.POLYGON];

  for (const chain of chains) {
    const response = await Moralis.EvmApi.nft.getWalletNFTs({
      address,
      chain,
    });

    allNFTs.push(response);
  }

  console.log(allNFTs);
};

runApp();

index.py (Python)

from moralis import evm_api
import json

api_key = "YOUR_API_KEY"
params = {
    "address": "0xd8da6bf26964af9d7eed9e03e53415d37aa96045",
    "chain": "eth",
    "format": "decimal",
    "limit": 1,
    "token_addresses": [],
    "cursor": "",
    "normalizeMetadata": True,
}

result = []
for chain in ('eth', 'bsc', 'polygon'):
    params['chain'] = chain
    result += [evm_api.nft.get_wallet_nfts(
    api_key=api_key,
    params=params,
    )]

# converting it to json because of unicode characters
print(json.dumps(result, indent=4))

Step 3: Run the script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

In your terminal, you should see the following JSON response:
