How Does an ERC-721 Token Work?
ERC-721 tokens, commonly referred to as Non-Fungible Tokens (NFTs), are distinctive digital assets that reside on the blockchain. If you’re curious about the workings of ERC-721 tokens, take a look at the mechanism outlined below, as explained by a mobile app development company.
1. Ownership and Verification
Each ERC-721 token is distinct and signifies ownership of a particular digital asset, which may include digital artwork, collectible items, virtual real estate, or any other one-of-a-kind entity. Users have the ability to confirm the authenticity and ownership of their NFT through the blockchain.
2. Buying and Selling
Users can trade ERC-721 tokens on various online platforms that act as marketplaces. These platforms streamline the transaction process, guaranteeing secure and transparent transfers of ownership. Notable NFT marketplaces include OpenSea, Rarible, and Axie Infinity.
3. Trading and Collecting
NFTs can be exchanged between users in much the same way as physical collectibles. Individuals have the opportunity to curate their own collections of NFTs that reflect their personal interests, which may include areas like digital art, sports memorabilia, or virtual real estate.
4. Using in Applications
Some NFTs provide functionality that extends beyond simple ownership. For instance, in blockchain-based games, NFTs can signify in-game assets that come with distinct features or capabilities. Additionally, in various applications, NFTs may offer access to special content or membership within exclusive communities.
5. Creating and Minting
Developers and companies specializing in cryptocurrency token development have the ability to design their own NFTs and mint them onto the blockchain. This process transforms digital assets into ERC-721 tokens, which can subsequently be sold or distributed to users.
Different Types of ERC Tokens
Before delving into ERC-721 token development, it is essential to have a solid understanding of the various types of ERC tokens. In essence, there are five key categories of ERC tokens that you should familiarize yourself with:
1. ERC-20 Tokens
On the Ethereum blockchain, ERC-20 is the predominant token standard used for the creation of fungible tokens. These tokens are interchangeable, meaning that each token holds the same value as any other token of its kind, allowing for easy swapping. ERC-20 tokens can serve various purposes, such as functioning as currency, representing shares, or acting as reward points. For instance, EIP-20 outlines the guidelines for approving and transferring tokens between addresses, as well as retrieving token balances and determining the total supply available.
2. ERC-721 Tokens
Another widely used standard on the Ethereum blockchain is ERC-721. Unlike ERC-20 tokens, each ERC-721 token is unique and holds its own distinct value. This feature makes ERC-721 ideal for representing assets such as real estate and in-game items. According to the guidelines established in EIP-721, the standard provides the necessary rules for aspects such as token ownership, moving tokens, and approving transfers, in addition to defining the total supply of unique tokens available.
3. ERC-777 Tokens
Initially, ERC-777 was developed to enhance the functionality of the ERC-20 standard. This new standard incorporates hooks that allow smart contracts to have greater control over the actions triggered when fungible tokens are sent or received. It was also designed to be compatible with ERC-20, enabling a way to react to these events. As such, contracts can indicate their support for this standard, ensuring that mistakenly sent tokens to incompatible contracts do not become locked—a common issue with ERC-20 tokens. The ERC-777 standard aims to simplify the process by allowing token approvals and transfers to occur in a single transaction, thereby streamlining interactions with numerical values.
4. ERC-1155 Tokens
ERC-1155 represents a newer standard for tokens on the Ethereum blockchain, facilitating the management of both fungible and non-fungible tokens within a single contract. This standard aims to improve upon the functionalities of ERC-20 and ERC-721 by offering enhanced capabilities. One of its key advantages is the ability to handle tokens in batches rather than individually, leading to cost savings. Additionally, ERC-1155 introduces a mechanism for token reception, further streamlining the transactional process.
5. ERC-4626 Tokens
ERC-4626 establishes a standardized API for tokenized or yield-bearing vaults, enabling the creation of smart contracts on the blockchain that facilitate token payments within these vaults. This standard simplifies the process of managing deposits and ensures that users receive tokens in return for their contributions. Essentially, these tokens are shares of a single ERC-20 token, representing an extension of that standard. The introduction of ERC-4626 addresses the challenges frequently encountered in lending and borrowing platforms, as well as market aggregators, enhancing the overall usability and effectiveness of such financial operations.

The `OwnerOf` method serves to identify the unique ID of a token, enabling the determination of its current owner. This is similar to how a specific address can be used to locate the owner of a house, linking the distinctive characteristics of the token to its rightful possessor.
3. SafeTransferFrom (without data)
The `SafeTransferFrom` function ensures that the ownership of a specific token can be securely transferred from one address to another. Additionally, it verifies whether the recipient is an NFT smart contract, confirming that it is capable of receiving the token without issues. This built-in safeguard helps to prevent any errors during the transfer process, promoting a seamless exchange of ownership.
4. TransferFrom
To modify the ownership of a token from one address to another, developers must utilize essential programming languages for implementing these changes. This process typically occurs when the developer has received the necessary permissions to execute the transfer.
5. Approve
The `Approve` function grants a designated address the authority to transfer a specific token on behalf of its owner. This capability allows for trusted transfers within the ERC-721 token framework, enabling the token owner to delegate the handling of their asset to another party while retaining ultimate ownership rights.
6. GetApproved
The `GetApproved` method retrieves the address that has been authorized to transfer a specific token. If no address has been approved, it returns a null address, indicating that no permissions have been granted for that token.
7. SetApprovalForAll
The `SetApprovalForAll` function allows the owner of one or multiple tokens to grant or revoke permission for an operator to manage all of their tokens. This can be likened to the process of appointing or dismissing a manager responsible for overseeing a collection of digital assets.
8. IsApprovedForAll
The `IsApprovedForAll` function determines whether an operator has been granted permission to manage all tokens belonging to a specific owner. If the operator lacks the requisite authorization, this function will return false, indicating that the user is not permitted to oversee the entire ERC collection.
9. SafeTransferFrom (with data)
The `SafeTransferFrom` function with an additional data parameter operates similarly to the standard `safeTransferFrom` function, yet introduces an extra data argument. This capability allows users to send a token to another party, particularly when interacting with smart contracts, while also including supplementary information that may be useful for processing the transaction or providing context.
