The key difference between creating an NFT as a single (ERC-721) on Polygon and using ERC-1155 with a quantity of 1 lies in the underlying token standards and their functionalities:

ERC-721 (Single NFT)
- Uniqueness: ERC-721 is designed for non-fungible tokens (NFTs), meaning each token is unique and cannot be replicated. It is ideal for assets like digital art or collectibles where uniqueness is the primary feature.
- Smart Contract Deployment: Each ERC-721 NFT requires its own smart contract, which can lead to higher deployment costs and complexity.
- Efficiency: ERC-721 transactions are slower and require more gas because only one token can be transferred at a time.
- Use Case: Best suited for individual, one-of-a-kind items like digital art or unique in-game assets.
ERC-1155 (Multiple NFTs with Quantity 1)
- Flexibility: ERC-1155 supports fungible, semi-fungible, and non-fungible tokens within a single smart contract. Even with a quantity of 1, it allows batch management and transfers.
- Smart Contract Deployment: A single ERC-1155 contract can manage multiple token types, reducing deployment costs and storage requirements.
- Efficiency: Transactions are faster and cheaper due to batch processing capabilities, even for single tokens. This makes it more cost-effective on networks like Polygon.
- Use Case: Suitable for managing collections or scenarios where scalability and efficiency are important, even if each token is unique.
Comparison Table
| Feature | ERC-721 | ERC-1155 (Quantity 1) |
|---|---|---|
| Token Type | Non-fungible | Non-fungible (with flexibility) |
| Smart Contract | Separate contract per token | Single contract for multiple tokens |
| Gas Efficiency | Higher | Lower |
| Transfer Speed | Slower | Faster |
| Use Case | Unique items like digital art | Collections or scalable systems |
In summary, if you need a purely unique NFT without scalability concerns, ERC-721 is ideal. However, ERC-1155 offers greater efficiency and flexibility even when minting a single NFT.
