Prove what you hold, without handing over your wallet
Sign a message with your wallet — it costs nothing and moves nothing — and get a link you can send to whoever asked. You choose whether the page shows the exact figure, a bracket, or only that you are above a number.
Your address never appears on the page, and links expire — seven days by default, or whenever you revoke them.
Sent here by a link? Each proof page lives at its own long, unguessable address like fundz.cc/l/…, so you need the whole thing. There is no directory here, on purpose: a list of who holds what is exactly what those long addresses exist to prevent.
