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

Step 1: Setup Moralis

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

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 = "0x26fcbd3afebbe28d0a8684f790c48368d21665b5";

  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 = "0x26fcbd3afebbe28d0a8684f790c48368d21665b5";

  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": "0x26fcbd3afebbe28d0a8684f790c48368d21665b5",
    "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:
