Property Version of an NFT

[Pelumi527]

Hi, is there way to use the property version of an NFT to know if it is V1 or V2?

[gregnazario]

Property version is associated with V1, and doesn't apply to V2.

Additionally, if you're using the indexer, there should be a field for token standard which is "v1" or "v2".

Yes, you could use indexer to figure out the token standard as we expose this field for tokens. An example query is here.

We also expose indexer queries through Aptos SDK, so that you could easily query it.

Oh Ok, but I am using nft-scan api, and all the token has a property version
This a V2 token but it has a property_version

Not familiar with what NFT scan uses for that field, especially since 1398 is a really arbitrary number.

(Also good to see you're snooping on my NFTs :) )

Oh alright thanks
😂😂 Oh didn't know it was your address, just picked a random address on Aptoscan
