Your machines mine with YOUR Bitcoin address. Read the five lines below, then sign with your wallet.
- Your machines mine with YOUR Bitcoin address. If a block comes, the satoshi go straight there, not to the manager.
- If your part is below 5,000 sat, you do not receive it: it stays in the pool fee.
- A long time can pass without any block. Nobody guarantees a payment, not even the manager.
- The manager can remove you only after 14 days without shares and must write the reason. You can ask to leave at any time from your page.
Transaction fees are added to the subsidy: the real block is worth more.
Your machines point here as pool 1 and 2. Each server keeps its own round: shares sent to another server during a failover count only in that server's round.
The Bitcoin address that receives your part of every block and that your machines use as username. It must be yours: you will sign a message with it.
Mainnet address starting with bc1q or bc1p (bech32). Legacy addresses (1… / 3…) are not accepted for now.
Pre-filled by the manager. Correct it if it is wrong: the manager sees both values.
Different from what the manager declared: the manager will see your value next to his.
Copy the message (or scan the QR), sign it with the wallet that holds the address, paste the signature here. Nothing is spent.
A signature cannot spend or move funds. It only proves the address is yours.
Scan with the wallet app to sign on the phone.
What the 5 lines mean
The message contains no amounts, recipients or transactions. If your wallet shows anything other than these 5 lines, do not sign.
How to sign with your wallet
Sign the message with the address you entered above: the wallet returns a signature (one line of text) and no key ever leaves the wallet. Copy the message with the button, do not retype it.
- Sparrow (PC · software wallet or hardware: Ledger, Trezor, Coldcard, BitBox, Jade): Tools → Sign/Verify Message → pick the address → paste the message → Sign (confirm on the device) → copy the Signature.
- Electrum (PC): Addresses tab → right-click the address → Sign/verify message → paste → Sign → copy.
- Electrum (Android): Addresses → tap the address → Sign/Verify → paste → Sign → copy.
- BlueWallet (Android/iPhone): open the wallet → ⋯ → Addresses → tap the address → Sign/Verify → paste the message → Sign → copy.
- Trezor Suite: account → ⋯ → Sign & Verify → pick the address → paste → Sign (confirm on the Trezor) → copy.
- Ledger: Ledger Live cannot sign messages. Connect the Ledger (Bitcoin app open) to Sparrow or Electrum and sign from there.
- Bitcoin Core: its “Sign message” window only accepts 1… addresses, so it cannot be used for bc1q/bc1p.
bc1p (taproot) addresses need a BIP-322 signature: today Sparrow with a software wallet does it. Hardware wallets do not sign taproot messages yet — use a bc1q address instead.
Before pasting: same address as above; message identical (use Copy); whole signature (it often ends with “=”). If it expires (15 min) press “New message” and sign again.
Verified by SoloFury: Ledger via Sparrow (October 2026). The other steps follow the wallets’ own documentation.
The signature was already accepted: finish the entry.
Point your machines to the home server with the settings below. The group is copied to the other servers within a few minutes.
Replace worker1 with a name for each machine. Pool 3 is the same group on another server: never use a plain solo port.
No account, no email: only your address and a signature. Questions: [email protected]
