Is there a tutorial anywhere on creating an NFT on TON?

This is a good suggestion for a dedicated step-by-step tutorial. I imagine that the TON community will focus on this in the coming months.

Here are some resources to help with creating NFTs:

  • TON-NFT-deployer: created by TON Diamonds, this is a complete project that can help the technically minded developer deploy an NFT
  • Disintar: an NFT marketplace for TON. You might want to look into here if you want to work as a creator instead of being more technically minded.
  • TON NFT Documentation: TON's documentation provides links to a lot of NFT resources.

Since smart contracts were mentioned, I'd like to include information on the standard and a smart contract implementation.

The standard is lengthy, and you can read the entire analysis on its GitHub page. Officially, the standard for NFTs on TON are TEP-62 (as opposed to ERC-721 on Ethereum).

As for the smart contract implementation, here is a simple one that the TON documentation provides, but there are many versions of it as well:

;;  TON NFT Item Smart Contract


    NOTE that this tokens can be transferred within the same workchain.

    This is suitable for most tokens, if you need tokens transferable between workchains there are two solutions:

    1) use more expensive but universal function to calculate message forward fee for arbitrary destination (see `misc/forward-fee-calc.cs`)

    2) use token holder proxies in target workchain (that way even 'non-universal' token can be used from any workchain)
