⛏️ Bitcoin Cash SHA256 Connection Guide
Choose the right lane, configure your miner, and connect to bch.hmpool.io with confidence.
⚠️ IMPORTANT: Choose the correct port for your miner's hashrate. Sending a stronger miner to a low-difficulty lane can produce unstable share timing and poor routing.
Choose Your Port

💰 Hybrid Payout System
HashedMax BCH Pool uses a hybrid PPLNS + finder's bonus system. When the pool finds a block:
- 1% Dev Fee — covers infrastructure, development, and transaction fees
- 5% Participation Bonus — split equally among miners connected 1+ hour before the block
- 20% Finder's Bonus — 20% of the full block reward goes to the miner who found the block
- 74% PPLNS Share Pool — distributed to all miners proportionally based on shares in the last 7 days
The block finder also receives their normal proportional share — the bonus is extra. This means every hash you submit is both a contribution to your steady earnings and a lottery ticket for the finder's bonus.
📊 Pool Information
- Pool Fee: 1%
- Payout Scheme: Hybrid PPLNS + Finder's Bonus
- Minimum Payout: 10,000 sats (0.0001 BCH)
- Force Payout: 90 days (balances above dust)

💡 Pro Tip: If you are unsure, start with the wizard on the homepage. It maps your max hashrate into the best starting lane and still lets vardiff fine-tune afterward.
