is there a spec that tells me to like where to put the asset data uri, the layer name, the trait name, layer id, trait id, etc.?

thanks

Here: https://github.com/sea-snake/ICRC/blob/fda2baab98434928f57a595f8ab94273f1f063b0/ICRCs/ICRC-97/ICRC-97.md

It’s linked in the WG overview as ICRC-97 here: https://github.com/dfinity/wg-token-standards

hi, on the 1st link, the status is still “draft” but on 2nd link the status is “approved”. may i know which one?

It’s approved as-in WG approved, not NNS approved yet as far as I’m aware.

Not sure what the current ICRC-7 adoption is on the IC currently, as far as I’m aware OISY only supports ETH (ERC-721/1155) and IC (EXT), not ICRC-7 yet.

  • Support for NFT collections from the ICRC-7 standard.

Not sure about the metadata part.

Thanks for all your feedback on Toko lol. ICRC-7’s gone the way of the dodo.

You’re right, seems like I missed that part :sweat_smile:

Diving a bit further into the code, OISY seems to have a specific set of icrc-7 metadata fields it reads for token details (e.g. image): https://github.com/dfinity/oisy-wallet/blob/712f4c297c600360c930281820e92dbb5c6a741f/src/frontend/src/icp/utils/icrc7.utils.ts#L348

So it’s likely ICRC-97, isn’t used by OISY at this moment. I’ll double check things with the OISY team, since I’m not actively involved with tokens related developments these days.
