How to connect an Antminer, Whatsminer or Avalon

Pool settings

On an Antminer open the miner's web page, then Miner Configuration → Pools (or Settings → Pools on newer firmware). Whatsminer: Configuration → CGMiner configuration or the WhatsMinerTool. Avalon: Configuration → Pool. Fill in pool 1:

Swap the port for the chain and mode you want: 3335 eCash solo, 3338 eCash shared, 3345 Bitcoin solo, 3348 Bitcoin shared. Save and apply; the miner reconnects within a minute.

• Use a bc1q… address from a wallet where you hold the private key or seed. That key receives your eCash or Bitcoin, Namecoin and Fractal Bitcoin rewards.
• Never use an exchange deposit address. Coinbase rewards sent there may be lost.
• bc1p (Taproot) and 3… addresses work for eCash and Bitcoin but are not paid on Namecoin, so bc1q is recommended.
• Rewards are spendable after 100 confirmations, like any coinbase.

All ports

The high-difficulty ports start each connection at difficulty 1,048,576 and never go below 262,144. A single ASIC can use either set; proxies, farms and rented hashrate should use the high-difficulty ports.

The d= password option

Vardiff tunes every connection to about 6–12 shares a minute, and settles even a very large connection within seconds. If you want to skip the burst of easy shares at the start, set a starting difficulty in the password. It is also the lowest difficulty the pool will set for that connection.

Options are separated by commas with no spaces. Add htr=H… to also earn Hathor, for example x,d=4194304,htr=H….

Proxies, fleets and ASICBoost

• Farm proxies (Braiins Farm Proxy and other stratum proxies): one upstream connection with many workers behind it is fine. Point the proxy at a high-difficulty port.
• ASICBoost: mining.configure version rolling is supported, so miners that use overt ASICBoost keep their efficiency gain.
• Extranonce: mining.extranonce.subscribe is supported, and extranonce2 is 8 bytes, which leaves plenty of room to split work between downstream machines.
• Many direct connections from one site are fine too. Each connection is kept to a few shares per second at most.
• Stratum V2 is on the roadmap, not available yet.

Worker names

Everything after the first dot in the user name is the worker name, used only for your own statistics: bc1q….row3-rack12. Machines with the same address are grouped as one miner with several workers on your miner page and the pool pages. Payouts always go to the address, never to a worker.

How large miners are paid

On solo ports the block pays the finder's address directly, minus 1%. On shared ports each block pays the miners in the recent-shares window (shares worth twice the network difficulty), by their share of the work, inside the coinbase. A coinbase holds a limited number of payout outputs, currently 19 miners plus the fee; the largest contributors are paid in that block and the rest keep their shares for a later block. The pool has no wallet, so it does not offer PPS or FPPS. See Farms and solo vs PPLNS.
