I am trying to display data on my front-end to help users comprehend how the smart contract works instantly.
To achieve that, we can call RPC from TonCenterAPI to get
net_item_index on the Collection Contract (followed the TEP62).
But the problem is, if I have 100+ users (customers) refreshing my website, then it's impossible for me to call an API for 100 times to get on-chain data. I must store the data in a database. Or, maybe there is something like TheGraph?
