SHA-256 and Scrypt pool for ASICs: merged mining, per-block autoswitch, fee from 2.9% down to 0.4%

Website · Coins · Calculator · FAQ · News · Telegram · Discord

Hi everyone,

We are the team behind Hash-Hut. We have been mining since 2015, and the pool started as a tool for our own farms: we wanted the hardware to move to the most profitable coin at the moment profitability changes, not a few minutes later. When it kept beating the pools we had used before, we opened it to everyone. Scrypt came first, SHA-256 was added in September 2025.

This thread is for questions, bug reports and criticism. The developers read it and answer here.

In short

Algorithms: SHA-256 and Scrypt, ASIC only
Coins: 30+. BTC, BCH, BSV, XEC, DGB, FB, QUAI and others on SHA-256; LTC + DOGE and a long list of merged coins on Scrypt
Autoswitch: on every new block, priced from the exchange order book, one stratum address per algorithm
Pool fee: 2.9% at the start, down to 0.4%. The grade goes up with hashrate, mining time, promo codes and invited miners, by public rules that apply automatically
Promo code for this forum: BITCOINTALK, +1 grade from the first day
Withdrawals: 0%, the pool pays the network fee. Daily payouts to your own wallet, no KYC
Servers: Europe, Asia, Russia, Belarus. Plain stratum and TLS on the same port
Languages: the site and the dashboard in 15 languages: English, Russian, Ukrainian, Belarusian, Kazakh, German, Spanish, French, Norwegian, Turkish, Arabic, Thai and Chinese (Simplified, Traditional for Taiwan and for Hong Kong)
Right now (mid-November 2026): about 1.27 EH/s on SHA-256 and 1.46 TH/s on Scrypt, around 7,000 workers online

1. Own nodes and large pools behind one address

A mid-size pool has a problem with big coins: it finds a BTC or LTC block rarely, so income swings a lot. We split the coins into two groups.

Smaller networks, where a pool of our size finds blocks often enough, run on our own nodes with a backend we wrote from scratch. BTC, BCH and LTC are forwarded to large public pools, so income on them does not depend on our luck. For you it is still one stratum address, one dashboard and a separate balance for each coin.

SHA-256
Our nodes	BSV, XEC, DGB, FB, BC2, BTCS, FIX, QUAI
Merged bonus	DOI, FB, ROD, TRC
Partner pools	BTC, BCH

Scrypt
Our nodes	DGB, CAT, FBX, SOH, QUAI
Merged bonus	B1T, BELLS, BQC, CRC, CY, DINGO, DOGE, FLIN, FLOP, JKC, LKY, MARS, MEWC, PEP, SHIC, TRMP
Partner pools	LTC with DOGE, PEP, BELLS, LKY, DINGO merged

QUAI is mined without merged coins.

We say this openly on purpose. Forwarding hashrate to a bigger pool is common in this business, and it is often not mentioned anywhere. With us you can see it: three primary coins, BTC, BCH and LTC (with the coins merged into LTC), are proxied to partner pools, and everything else is mined on our own nodes. Every coin page shows how the coin is mined ("Our nodes" or "Partner pool"), its reward system, pool hashrate and the latest blocks, so you always know which coins are proxied and how the reward for them is calculated: hash-hut.net/mining

Behind that one address is the largest and most complex part of our code. It moves every worker between our own nodes and several partner pools, compares their profitability on every block, checks the work coming from partner pools against our own full nodes, and takes the worker to another coin if a partner pool goes down. All of this happens without reconnecting the ASIC. For you it looks like one pool.

2. Autoswitch that follows blocks, not a timer

Most profit switching re-checks profitability every few minutes. Until the timer fires, the ASIC keeps hashing a coin that may no longer be the best one, and the switch itself often costs a reconnect and some stale shares.

Ours is driven by events:

Our nodes report every new block on every network we follow.
Profitability is recalculated at that moment from the block reward and the current difficulty.
The price is not the last trade. It comes from the buy side of the exchange order book at a depth you choose: Real (best bid), Deep (enough to fill a small one-off sale) or Deepest (enough to fill a large one). A coin with a thin order book will not look more profitable than it is when you actually sell it.
If the leader has changed, the ASIC gets work for the new coin at the moment it would receive a new job anyway. No reconnect, no hashrate dip, no stale shares caused by the switch.

You can exclude coins for a worker, or turn autoswitch off and pin the worker to one coin. This is done in the dashboard, nothing changes on the ASIC. There is no extra charge for autoswitch. Details: hash-hut.net/autoswitch

3. Fee: from 2.9% down to 0.4%, and not only by hashrate

2.9% is the fee you start with, not the fee you stay on. The table below is sorted by hashrate, but hashrate is only one of three ways to move down it. Bonus grades are added on top of your hashrate grade, and each of them moves you one row down:

Mining time. 160 mining days out of the last 180 give +1 grade forever, 305 out of 360 give a second one, 670 out of 730 a third. That is up to three rows down on the same hardware. The fee starts moving toward the next grade while the days add up, not only on the day the bonus is earned. A day counts when your daily average reaches the Worker level on either algorithm.
Promo code. +1 grade for a limited time, at any hashrate. For readers of this forum the code is BITCOINTALK: enter it in the dashboard after signing up, the expiry date of the bonus is shown there.
Invited miners. Half of their hashrate is added to yours when the grade is calculated.

Example: three S21s, about 600 TH/s. By hashrate that is Worker, 2.5%. After 160 days of mining it is Farmer, 1.95%. After 305 days it is Industrial, 1.35%, with no new hardware, and after 670 days it is Whale, 0.75%. A promo code moves each of these steps one more row down while it is active.

There are no private deals and nothing to apply for. The grade is recalculated once a day and shown in the dashboard together with what is left to the next one.

Grade	SHA-256	Scrypt	Fee	Fee is reached	Or with bonuses
Newbie	below 500 TH/s	below 10 GH/s	2.9%	at the start	-
Worker	from 500 TH/s	from 10 GH/s	2.5%	over 7 active days out of 14	Newbie +1 (promo code)
Farmer	from 5 PH/s	from 50 GH/s	1.95%	over 14 active days out of 28	Worker +1
Industrial	from 30 PH/s	from 500 GH/s	1.35%	over 28 active days out of 56	Worker +2 / Farmer +1
Whale	from 100 PH/s	from 1.5 TH/s	0.75%	from day one	Worker +3 / Farmer +2 / Industrial +1
Legend	from 300 PH/s	from 5 TH/s	0.4%	from day one	Farmer +3 / Industrial +2 / Whale +1

The hashrate columns count your own average plus half the hashrate of the miners you invited. "+1" in the last column is one bonus grade: a mining-time bonus or an active promo code.
Active days are counted in a sliding window, so a few days offline do not reset your progress.
On coins mined through partner pools the 2.9% already includes that pool's fee (0.35% to 0.75%). The grade lowers only our part, so at the higher grades the total on those coins is slightly above the table.
Withdrawals are free at every grade.
Invited miners: a lifetime reward of 0.5% to 1.2% depending on your grade, never more than the fee the invited miner pays.

4. Rewards and payouts

Coins on our nodes use our own share-based scheme (shown on the site as CUSTOM30M-48H). Every share you submit between blocks is counted and stays valid for up to 48 hours. You are paid for a block even if you disconnected before it was found, and a pool hopper gets what their shares were worth and nothing more. There are no rounds and no "last N shares" window to fall out of, so it works for rented and unstable hashrate too. The whole block reward is distributed, transaction fees included.
Coins through partner pools: the partner pool pays us on its own scheme: FPPS for BTC and BCH, PPS for LTC, PPLNS for the coins merged with LTC. We then split what arrived from the partner pool among our miners in proportion to their shares. That is why the site shows these systems with a PRO prefix: PROFPPS, PROPPS, PROPPLNS. Day to day the result is almost the same as mining on that scheme directly, but you are paid a proportional part of what the partner pool actually credited, not a fixed price per share from us.
Payouts go out every day at 12:00 UTC to the address you set for each coin, once the balance reaches the minimum (BTC 0.0001, BCH 0.005, LTC 0.01, DOGE 5). Several small coins are paid every 15 minutes. An exchange deposit address works as well.
Checking us: the Accruals page lists every accrual together with the fee that was applied. Blocks, pool luck and the top miners are public.

Rejected shares on the coins we process ourselves stay around 0.03% with healthy hardware and a stable connection. Do not take our word for it, look at your own worker statistics after a day.

5. Connecting

Sign up (it takes a minute, no KYC), add your wallet addresses and point the ASIC to the nearest server:

Code:

SHA-256:   stratum+tcp://eu.pool.hash-hut.net:8888
Scrypt:    stratum+tcp://eu.pool.hash-hut.net:9999

Regions:   eu (Germany), asia (Singapore), ru (Russia), by (Belarus)
           e.g. stratum+tcp://asia.pool.hash-hut.net:8888
TLS:       same host and port, stratum+ssl:// instead of stratum+tcp://

Worker:    YOUR_STRATUM_ID.worker_name
Password:  empty, or x

Your Stratum ID is shown in the dashboard and in the FAQ once you are logged in. The worker appears under Workers in a couple of minutes. The coin and the autoswitch mode are chosen there, for one worker or for many at once.

NiceHash: set a static difficulty in the password, d=1024000, and if needed a minimum difficulty after a comma: d=1024000,md=1024000.
MiningRigRentals and regular ASICs: leave the password empty, vardiff does the rest.
Whatsminer: for anything other than BTC and BCH use firmware from 2025 or newer, set CoinType to DGB in the pool settings and connect with the password wm=1. Older firmware handles non-BTC work badly. The dashboard flags such workers.

6. Dashboard and tools

Sub-accounts with their own Stratum IDs, for hosting clients or separate farms
Watcher links: view-only access where you choose which sections and which dates are visible. One link can cover all sub-accounts
Telegram bot: worker offline or back online, hashrate drop, too many rejected shares
REST API with tokens limited to the data you choose, and a public WebSocket feed with live profitability
2FA, income calculator with ASIC presets, hashrate charts updated every minute
Support is people, not bots, in Telegram and Discord around the clock

7. What we do not have

No auto-conversion into one coin yet. You are paid in the coins your hardware mined, so you need an address for every coin you want to withdraw. Conversion is planned.
SHA-256 and Scrypt only. No GPU or CPU algorithms.
We do not find BTC, BCH or LTC blocks ourselves, that hashrate goes to large pools. If you want your hashrate on an independent block template, we are not the right pool for those three coins.
You need an account. There is no anonymous mode with a wallet address as the username, and this is on purpose. We watch share statistics for attacks that reduce everyone's rewards, such as withholding block solutions, and we block the accounts behind them. It has happened several times, and each case is described on our news page. With anonymous addresses an attacker would simply come back under a new one. Signing up takes a minute and needs no KYC.

Try it on one machine

Point a single ASIC at the pool for a day or two and compare it with what you run now: accepted and rejected shares, what was credited, what arrived in the wallet. If our numbers are worse, write it here. We would rather hear it.
