NFT - How to Create NFT Collections

To mint an NFT, first you need a Collection to which said NFT must belong. To create your own NFT Collection, you have to deploy your own SmartContract. Tatum makes these steps easy.

Creating an NFT Collection

1. Select the network you want the NFTs to exist.
2. Have ready an address with its privatekey with native assets. Required to pay for the SmartContract deployment.
3. Pick on a "name" and "symbol" for your collection.
4. Deploy the NFT SmartContract to get your Collection.
5. (Optional) Add a Tatum minter address
   1. If a Minter address is added to the Collection SmartContract, Tatum pays on your behalf. Your account will be charged accordingly.
