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
- Open your miner's configuration screen — for an ASIC this is its web interface; for an OverMiner device it is the setup portal.
- Set the pool URL to the endpoint from the table above that matches your hardware.
- 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.
- Leave the password field at whatever default your miner uses. The pool does not check it.
- 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.
