Credentials

Miner configuration (most coins)

Username:  YOUR_WALLET_ADDRESS.workerName
Password:  x

Litecoin + Dogecoin merge (AuxPoW)

Username:  YOUR_LTC_ADDRESS.workerName
Password:  doge=YourDogeAddress

The part after the dot is your worker name — use any label you want (e.g. antminer-s21, garage-rig). For LTC, set password to doge=YourDogeAddress to earn LTC + DOGE via AuxPoW merge mining. Direct DOGE mining on the DOGE stratum (password x) still works.

Configuration examples

Miner web interface / software (ASIC, GPU, or CPU)

Pool URL:  stratum+tcp://btc.bitmernsolo.com:3132
Worker:    YOUR_WALLET_ADDRESS.worker1
Password:  x

CGMiner / BFGMiner (command line)

cgminer -o stratum+tcp://btc.bitmernsolo.com:3132 \
  -u YOUR_WALLET_ADDRESS.worker1 \
  -p x

Worker Configuration

Workers are identified by the label after the dot in your stratum username.

Naming format

WALLET_ADDRESS.workerName

Use letters, numbers, and hyphens. Keep names short and descriptive — they appear in your dashboard exactly as entered.

Multiple workers

Run as many workers as you want under the same wallet address. Each gets its own hashrate chart and status. Use a different name for each machine.

bc1q...abc.s21-pro
bc1q...abc.s19k-garage
bc1q...abc.bitaxe

Dashboard visibility

Each worker appears as a separate row in your Miners page with its own hashrate, shares per second, and online/offline status. Click into any worker to see its 24-hour hashrate chart and connection details. Workers are automatically detected when they connect — no manual registration required.

Open the Miners page in the dashboard for the live worker table and per-worker 24-hour charts.

VarDiff

Variable Difficulty automatically adjusts the share difficulty sent to your miner based on how fast it's hashing.

How it works

VarDiff monitors how quickly your miner submits shares and adjusts difficulty up or down to maintain a steady submission rate. This prevents flooding the pool with easy shares (wasting bandwidth) or struggling with shares that are too hard (making stats laggy).

Starting difficulty

Each port has a different starting difficulty — this is just where VarDiff begins. It adjusts to your actual hashrate within minutes. If unsure which port to use, pick the default (highest starting difficulty) port. It works for everyone.

Port selection guide

Your hashrate	Recommended port	Examples
Low / entry-level	Lowest available port	Bitaxe, small GPUs/CPUs, older ASICs
Mid-range	Low or medium port	Single mid-range ASIC, typical GPU/CPU rigs
High / multi-unit	Default (highest) port	Flagship ASICs, large GPU farms, multi-CPU setups

Fees & Payouts

1% flat fee — deducted only when you find a block. No block, no fee. No hidden charges, no subscription, no withdrawal fees.

When is the fee deducted?

When your miner finds a block, the pool deducts 1% from the block reward before sending the remaining 99% to your wallet.

Payout flow

Block found → confirmations accumulate → coinbase matures → 99% sent to your wallet automatically. No manual action needed.

Payout examples
