How to Connect

← 88pool

No registration. Your BTC address is your account. The block reward is paid straight to your address in the coinbase — the pool never custodies your coins.

💸Pool fee is 2%. When a block is found the coinbase is split on the spot: 98% to your address, 2% to the pool. There are no other charges, no payout schedule and no minimum.

1. Pick an endpoint

Use Stratum V1 on port 3333 unless your firmware supports Stratum V2 on 3346.

2. Username = your address

Optionally append .workerName, e.g. bc1q…rig01. The password is ignored.

3. Start mining

Your rig shows up on the stats page within a few minutes after its first share.

Endpoints

Mining URL (Stratum V1)
stratum+tcp://solo.88pool.com:3333
Username = your BTC address, password can be anything
Mining URL (Stratum V2)
stratum2+tcp://solo.88pool.com:3346/9cUhuBpM8KakJgZHJruzSBwLtWCKuqRGfENV4ESToJbqBfuvhdc
Requires SV2 firmware, otherwise use V1 above
Rentals

Mining rentals (high-diff port)

Pointing rented hashrate (NiceHash, MRR, etc.) at this pool? Use the high-difficulty port below. Username is still your BTC address, password can be anything.

Mining URL (Stratum V1)
stratum+tcp://solo.88pool.com:4334
Mining URL (Stratum V2)
stratum2+tcp://solo.88pool.com:4336/9cUhuBpM8KakJgZHJruzSBwLtWCKuqRGfENV4ESToJbqBfuvhdc

Why: rented hashrate can be tens of TH/s. On the normal port every share is tiny and would flood the pool, so share difficulty is pinned at 1,000,000 here.

Command line example

cgminer -o stratum+tcp://solo.88pool.com:3333 -u <YOUR_BTC_ADDRESS>.rig01 -p x
bfgminer -o stratum+tcp://solo.88pool.com:3333 -u <YOUR_BTC_ADDRESS>.rig01 -p x

FAQ

Why is my hashrate not showing?

The pool raises share difficulty to match your hashrate. A low-power rig may take 10+ minutes to submit its first share, and stats only appear after that. You can also set a lower client difficulty in your firmware (minimum 1). Shares are feedback only — they do not change your odds of finding a block.

What do I put as username?

Your BTC address. You may append .workerName. The password is ignored.

How much hashrate makes sense for solo?

Below roughly 100 GH/s you will realistically never find a block. Treat it as a lottery ticket, not income — check the block-chance table on your stats page.

Where do the rewards go?

The coinbase pays your address directly. The pool never custodies your coins and there is no payout schedule or minimum.

Stratum V1 or V2?

Use V2 on 3346 if your firmware supports it — better security, less bandwidth. Otherwise V1 on 3333 works with every ASIC.

Heads-up: Solo mining is high variance. With a small hashrate you may mine for months without a block and then receive a full reward at once.
