ERC-721 Tokens: A Complete Guide
In the world of blockchain and cryptocurrencies, tokens are a crucial element. ERC-721 has gained significant attention among the various token standards, particularly in non-fungible tokens (NFTs). Unlike fungible tokens like Bitcoin or Ethereum, which are interchangeable and hold the same value, web3 tokens represent unique assets. This uniqueness makes them ideal for digital collectibles, art, gaming, and more.
What is ERC-721?
ERC-721 is a standard for creating non-fungible tokens on the Ethereum blockchain. It was proposed by William Entriken, Dieter Shirley, Jacob Evans, and Nastassia Sachs in January 2018. The main features include:
- Each token has a unique, distinct value and cannot be replaced with another token.
- The ownership of each token is recorded on the blockchain, providing proof of authenticity and ownership.
- Ethereum Standard tokens can be used across various platforms and applications that support the standard.
How ERC-721 Tokens Work
Smart Contracts: A smart contract defines ERC token functionalities by directly embedding the terms of the agreement into code. This contract manages the creation, ownership, and transfer of NFTs, wherein smart contract engineers programmatically handle smart contracts.
Uniqueness: Each token in an ERC-721 smart contract has a unique identifier (token ID) to distinguish it from other tokens. This ID is typically an unsigned integer.
Metadata: Ethereum tokens can include metadata describing the specific asset the token represents. The creator can store this off-chain (e.g., in a database) or, in some cases, on-chain, depending on their implementation.
Ownership and Transfer: The smart contract ensures that the ownership of tokens is tracked and can be transferred between users, ensuring that the ownership history is immutable and transparent.
Compatibility: ERC-721 crypto tokens are compatible with existing wallets and marketplaces that support the standard, facilitating transactions.
To better understand how ERC-721 tokens work, let’s explore a real-time example: the ERC-721 NFT Marketplace.

The contract imports OpenZeppelin’s ERC721 implementation and an Ownable contract to handle basic ERC-721 functionalities and ownership.
Deploying the Smart Contract
To deploy this smart contract, you would typically use a development environment Remix IDE, or a framework like Truffle or Hard Hat. Once you deploy the contract, various wallets or decentralized applications can interact with it.
