Your payout address
Where the prize lands if your machine finds the key. No wallet? Any wallet app gives you an address free.
finder takes all
On a win, the transaction is built locally and submitted privately (never the public mempool, which gets front-run). No address? The prize routes to the pool address as a safety fallback so a win is never lost — set your own to keep it. The optional split (a share to the pool/supporter) is off by default and shown before anything is signed.
