People found it easy to create NFTs but there were some questions about the steps to enter by submitting the transaction IDs for creating the NFTs and then sending the NFT to the registration wallet address. Both those steps are completed on the blockchain by sending a transaction, which creates a unique transaction ID. Creating vs. sending and NFT can be distinguished because creating the NFT requires about 240,000 to 300,000 gas (to power the smart contract) while sending the NFT requires about 30,000 to 54,000 gas:

Create NFT Gas Used 243,359, Send NFT Gas Used 53,709

The gas used is shown after the transaction is published in the next block.

Another issue people encountered was the “status code 404” error. After sending a transaction, if you immediately click on the green transaction ID link the transaction has not yet propagated through the Web Wallet backend to the blockchain. The transaction is not even in the “mempool” (waiting to be published), so the explorer can’t display the transaction and gives this error. If you encounter this “status code 404” error, wait a few seconds and refresh the browser to see the transaction. Once the transaction publishes in the next block it will show a confirmation and (for smart contract transactions) the gas used.
