<p>Yes, there is. Anyone with synced blockchain can verify that a transaction took place.<br>
Grin Documentation - Proof of Payment</p>
<p>EDIT: In that Bisq forum thread posted by <a class="user-mention" data-hovercard-type="user" data-hovercard-url="/users/m52go/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/m52go">@m52go</a> above, someone suggest a website that can also provide proof of payments, if syncing Grin blockchain should be an issue for mediators. However, it is quite an old post and I don't have any experience with that.</p>

<p>Just a short update on this topic:</p>
<p>Yes we from <a href="https://grinnode.live/" rel="nofollow">Grinnode.live</a> are still working on a solution for this problem.<br>
At the moment we are developing a public API which anyone can query, when activated and use it to verify of a payment. This can be useful when you are a <code>mediator</code> or <code>arbitrator</code><br>
It can be activated via GRIN and has a standard <code>JSON API</code> to query if a transaction did take place and we might also provide a front end for it if required.</p>
