DAML and NFTs

Hi, Can anyone explain how to use DAML to create an NFT of a data object, such as a PDF file?one signatory is clear but how would this DAML contract interact with an exchange wanting to list it? easier done as an ERC 20 token?

if not, how would a DAML NFT get traded?

ERC 721, Sorry

Which ledger are you thinking about as the DAML runtime?

If the exchange implements ERC 721 (which is an Ethereum API) you need a bridge between DAML and the exchange.

You could build your own exchange with an ERC 721 like DAML contract, but then no one could interact with it, unless you create something Metamask like.

Maybe DAML + Besu could make this easier as it is Ethereum → Ethereum?

Thank you

Bridge between DAML and the Exchange?

seems it would be easier to just do a a native token rather than use DAML.

I wrote something on NFTs in Daml here. But @perbergman is right, a Daml NFT is a Daml NFT, not an ERC 721 token on Ethereum. If you want an ERC 721 token on Ethereum to trade on a public crypto exchange, I’d use a different technology made for that specific purpose.
