Description

We should add filters to the ListAssets call, so that only assets that satisfy certain criteria are returned.
Examples of such filters could be:

• GroupKey: only return assets that belong to the group with this key
• MinAmount: only return assets with amount greater or equal to this value
• MaxAmount: only return assets with amount less or equal to this value
• ScriptKey: return all assets that use this script key
• AnchorOutpoint: return all assets that are currently anchored on this outpoint
