NBA Top Shot architecture reverse engineering

1

Hello,
we’re trying to reverse engineer how NBA Top Shot is working and one of the main things is to understand where certain resources (metadata) are stored and what is stored on-chain and what off-chain.
Example:
Series - are they stored in private storage of the Admin account only?
Sets - same question
Plays - are they stored within the Moment NFT or?

Account Details - I guess those are stored off-chain inside a DB

Series, Sets, Plays all stored on contract.

Tnx @bluesign that makes sense. Is there a simple “storage explorer” out there or do I need to build my own to see the metadata?

metadata is on contract, with script you can get all.

ok, tnx @bluesign - I’ve build a basic NBA Top Shot explorer
