An NFT smart contract is a self-executing contract with the terms of the agreement directly written into code. These contracts are deployed on a blockchain, most commonly Ethereum, and they govern the creation, transfer, and verification of NFTs. Unlike fungible tokens like Bitcoin or Ethereum, which are identical and interchangeable, each NFT is unique and cannot be replaced with another token.

NFT smart contracts utilize standards such as ERC-721 and ERC-1155 on the Ethereum blockchain. The ERC-721 standard defines a minimum interface a smart contract must implement to allow unique tokens, specifying methods for transferring tokens and checking ownership. ERC-1155 goes a step further by enabling contracts to manage multiple types of tokens, including both fungible and non-fungible tokens.

How does NFT Smart Contracts work？

uring the uniqueness and authenticity of each token.

When an NFT is minted, a smart contract is deployed on the blockchain that assigns a unique identifier (token ID) to the digital asset. This token ID, along with metadata such as the asset's name, description, and often a link to the digital file (e.g., artwork, music, or video), is stored on the blockchain. The metadata provides detailed information about the asset, although it is usually stored off-chain due to the large size of digital files. The smart contract guarantees that each token is unique by ensuring that no two tokens have the same ID, thus preventing duplication.

Transferring ownership of an NFT involves several steps facilitated by the smart contract. The current owner initiates the transfer by calling a function within the smart contract, specifying the recipient's address and the token ID of the NFT being transferred. The smart contract then verifies that the sender is indeed the rightful owner of the token by checking the blockchain records. Once ownership is confirmed, the smart contract updates the blockchain to reflect the new owner's address. This process ensures that all transactions are transparent and verifiable by anyone on the blockchain, thereby maintaining trust and security within the system.

NFT smart contracts typically conform to standards such as ERC-721 or ERC-1155 on the Ethereum blockchain. The ERC-721 standard defines a set of rules for creating non-fungible tokens, including methods for transferring tokens and checking ownership. ERC-1155, on the other hand, allows for the creation of contracts that can manage multiple types of tokens—both fungible and non-fungible—within a single contract, offering greater flexibility.
