Solo mining

Connecting a miner to the OverBuild Labs pool

The OverBuild Labs pool is a solo pool. Block rewards are paid directly to your wallet by the Kaspa network — we never take custody of your coins, and there are no pool fees.

Before you start

You need a Kaspa wallet address. Any Kaspa wallet works; the address is the only thing the pool needs from you.

Double-check the address before you start mining. Rewards are paid by the network to whatever address you configure, and a block sent to a wrong address cannot be recovered.

Choose the right port

The pool runs three stratum endpoints. They differ in starting difficulty, and picking the wrong one will cause problems — a high-hashrate ASIC pointed at the lowest-difficulty port can be overwhelmed by share submissions.

Your hardware Endpoint Starting difficulty
OverMiner, OverMobile, other low-hashrate devices stratum+tcp://pool.overbuildlabs.com:5558 0.0000001
KS0, KS0 Pro, KS0 Ultra stratum+tcp://pool.overbuildlabs.com:5559 8
KS1 and higher ASICs (1+ TH/s) stratum+tcp://pool.overbuildlabs.com:5560 128

Configure your miner

  1. Open your miner's configuration screen — for an ASIC this is its web interface; for an OverMiner device it is the setup portal.
  2. Set the pool URL to the endpoint from the table above that matches your hardware.
  3. Set the worker or username field to your Kaspa wallet address. You can append a worker name after a dot if your firmware supports it.
  4. Leave the password field at whatever default your miner uses. The pool does not check it.
  5. Save and restart the miner.

Confirm it is working

Within a minute or two your device should appear on the pool statistics page. If it does not:

  • Check that the port matches your hardware tier.
  • Confirm the wallet address has no leading or trailing whitespace.
  • Make sure outbound connections on the stratum port are not blocked by your firewall or router.

What to expect

Solo mining is all-or-nothing. You are not earning a share of someone else's block — you are trying to find a whole block yourself. For lottery-tier hardware this can mean years without a single block. Mine because you want to support the network and enjoy the hardware, not because you expect a return.
