Credentials

Miner configuration

Username:  YOUR_WALLET_ADDRESS.workerName
Password:  x

The part after the dot is your worker name — use any label you want (e.g. antminer-s21, garage-rig). Password can be anything.

Configuration examples

ASIC web interface (Antminer / Whatsminer)

Pool URL:  stratum+tcp://btc.bitmernsolo.com:3102
Worker:    YOUR_WALLET_ADDRESS.worker1
Password:  x

CGMiner / BFGMiner (command line)

cgminer -o stratum+tcp://btc.bitmernsolo.com:3102 \
  -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.

Bitmern miners page showing a table of 8 workers, each with name, online status, current hashrate, 24-hour average, reject rate, and last share time — The Miners page lists every connected worker with live stats.

Worker detail view for s9vbos showing current hashrate of 10.82 TH/s, 1h and 24h averages, shares per second, last share time, and a 24-hour hashrate area chart — Click into any worker to see its 24-hour hashrate chart and detailed stats.

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
< 10 TH/s	Lowest available port	Bitaxe, NerdMiner, older ASICs
10–100 TH/s	Low or medium port	Single mid-range ASIC
100+ TH/s	Default (highest) port	Modern flagship ASICs, multiple units

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

Coin	Block Reward	1% Fee	You Receive
BTC	3.125 BTC	0.03125 BTC	3.09375 BTC
LTC	6.25 LTC	0.0625 LTC	6.1875 LTC
DOGE	10,000 DOGE	100 DOGE	9,900 DOGE
BCH	3.125 BCH	0.03125 BCH	3.09375 BCH
DGB	665 DGB	6.65 DGB	658.35 DGB

Confirmation requirements

Blocks must reach these confirmation counts before the coinbase reward matures and payout is sent.

Coin	Confirmations	Approx. time
BTCBitcoin	100	~16 hours
LTCLitecoin	60	~2.5 hours
DOGEDogecoin	40	~40 minutes
BCHBitcoin Cash	100	~16 hours
DGBDigiByte	240	~1 hour
