How post verification works

FRONTIER reads your public post from X on its own server and checks it carries your claim code.

When you submit a post link, FRONTIER’s server fetches the post from X itself. Nothing your browser says about the post is trusted. The post must contain your claim code and mention $FRONTIER, and when X provides a timestamp, it must be newer than the claim.

Protected accounts can’t be read, so claim posts must be public. Deleting the post afterwards doesn’t undo a claim, but a post can only ever be used once. The code only unlocks a claim for the wallet that requested it, which still has to sign.
