createCrosspost requires a fully loaded comment with comment.cid and comment.raw.comment. Publish the returned payload through the existing action hook:

const crosspost = createCrosspost(sourceComment);
const { publishComment } = usePublishComment({
  communityAddress: targetCommunityAddress,
  title: sourceComment.title,
  crosspost,
});
await publishComment();

Render the author-signed embedded record immediately with useCrosspost. The referenced community is only confirmed after its signed CommentUpdate has loaded, exposed as isCommunityVerified:

const original = useCrosspost({ crosspost: post.crosspost });

return <CrosspostCard comment={original} verified={original.isCommunityVerified} />;
