NFT Creation (ARC3)

NFTs on Algorand are created using the Algorand Standard Assets (ASAs), which are part of the core protocol and created using a special type of transaction. This makes Algorand different to other chains where smart contracts are needed for the creation of an NFT. You can learn more about it here.

ARC Standards we support:

• ARC-003 Standard
