Rehearsal

Can your wallet howl?

On August 28, 2026 at 04:18 UTC, a one-hour window opens. In it, you send a marked transaction to yourself — your $DOG never leaves your wallet — and the Pack Book records that you were there.

This page builds that exact transaction now, with your real address and the real marker, and stops before anything is signed. It answers one question: whether your wallet can take part.

Nothing here is signed. Nothing is broadcast. This page runs no analytics and sets no cookies — open your browser tools and check. To answer the question it asks two public sources about your address: mempool.space and our own endpoint. We build no profile and keep no account for you. Like any website, a request reaches a server and a host keeps its own logs — that part is not ours to promise, so we don't.

What a howl requires

  • 100,000 DOG held in your own wallet at the snapshot block. This is the backing that makes the Scoreboard hard to fake — an address below it cannot howl, however early it arrives.
  • A small amount of BTC in the same wallet, to pay the miner fee. See the cost below.
  • Self-custody. DOG on an exchange cannot howl — the transaction has to come from an address whose keys are yours.

The window opens once and closes in an hour. Put it in your calendar first — that is the part that decides whether you are there.

The address types above are what the code accepts, proven by test. Which wallet produces which type is inferreduntil someone rehearses and says so — that is why the failure message asks for the wallet's name. We would rather publish an honest gap than a guessed table.
