With Blockfrost, I can easily query which assets belong to a staking address using /accounts/{stake_address}/addresses/assets
. I would like to use this approach to allow users to associate their accounts with an ADA Handle. However, I don't see an easy way to check when the Handle has been moved to a different wallet (besides querying Blockfrost every x hours). Is there a better approach using Blockfrost? Should I look into hosting a node instead?
Using Tango (so not Blockfrost), this should be possible in two weeks. See here.
