@Christoph We have discussed a solution that would enable a user to visualize their VTXOs’ branches, without revealing the rest of the associated transaction trees. Essentially, the user could copy-paste their VTXO data to the end of a URL on a block explorer, which would be everything the browser needs to render the exit information. Something like: https://blockexplo.rer/api/ark#<hex_encoded_vtxo_data>.
Could be useful for users wanting to analyze their exit situation, costs, etc. with a third party.
Something we’re working on in the background, but it won’t be ready till post-launch.
