NFToken is a simple, cheap NFT standard for Solana.
Creating an NFT with NFToken costs about 2M Lamports or $0.08.
With Metaplex, this costs about 10M Lamports or $0.32.
Metaplex requires 4 separate accounts for each NFT. This makes it incredibly difficult to do simple queries like finding all NFTs and owners for a collection. In addition, this complex structure has caused security issues.
NFToken is simple which makes it easy to build on top of and query.
These docs are interactive. That means you can get started without even opening the terminal. You can even create a primary drop (equivalent of Candy Machine) without installing anything.
You can create an NFT in just a few seconds.
If you're a developer, this is easy to understand and code up. Check it out the code in the next section.
