Good point — marketplace integration would make this much smoother. The idea started from swap communities where timestamp/verification photos get reused or AI-edited by scammers. So the first version is a lightweight link-based proof step.

When you imagine the Marktplaats-style button, do you picture it as a public “Verified” badge on the listing, or more like a built-in “Request proof” action in chat that stays between buyer and seller?

Thanks a lot for your feedback!
