We are building a Discord holder verification tool on solana and we are almost done with 80% work
We are using metaplex SDK to find nfts in the wallet of users.
But we have one query how to have a watch on wallet activity ?
How to know if one user has sold his nft and how will it triggers in discord that the role is removed ?
We know how to remove role in discord but we don't know how to remove users role within minutes if nft owner gets changed.
We have an route that does all the conditions check for all the user ?
But how is that possible to hit that route every 5 seconds for 1000 of users ?
