Connect a miner

Point any Stratum v1 miner at BitcoinII SOLO Pool, or use the new encrypted Stratum V2 endpoints. There are no accounts. The username is your payout address.

Quick start

  1. Pick a tier below close to your hashrate, or use the vardiff tier if unsure.
  2. Set username to your-payout-address.worker. For example: YOUR_ADDRESS.rig01.
  3. Password is ignored by default, unless you specify custom parameters (e.g. custom static difficulty like d=524288).
  4. Hit start. Stats appear in seconds on the Address page.

For most home miners like Bitaxe, Nerdaxe, Avalon, etc; you should use vardiff port. For rental marketplaces like Braiins, Nicehash, MiningRigRentals, you should choose fixed difficulty ports.

vardiff
Auto-adjusting difficulty based on rolling dual-EMA hashrate calculations. Highly recommended for small to medium miners like Bitaxes, Nerdaxe, Avalon Nano, etc.
💡 Custom Static Difficulty Supported:Pass d=524288 or diff=524k in the password parameter to lock in your own custom static difficulty (clamped between 1,024 and 1,000,000).
