Point a Miner ​

This guide is the connection step, after the pool's payout rule is settled. Name the pool is that decision. Come back here only when you know who is paid if a block is found.

The project does not ask for an account on this website. There is no signup.

Your own instance ​

The v2.6.0 compose file listens for Stratum on port 3333. From a miner that can reach the host:

text
stratum+tcp://YOUR_HOST:3333

On the pool machine itself the host is localhost. From another machine it is that machine's address, and only if you have deliberately published the port.

What you type as the username depends on the mode you configured.

  • The Foundation's donation instance wants a label. That rule is below. It is not the default for a pool you just installed.
  • The changelog says a 100% donation setting is what skips Bitcoin-address checks. If you did not set that, the project expects addresses. The release example tells you to put your address in bootstrap_address. Set every payout address in the config before other people connect.
  • This guide does not invent a worker-name grammar for paying pools beyond that. The README does not give one. If your firmware wants address.worker, confirm it against a current Hydrapool issue or the forum before you treat it as a rule.

The worker password is whatever your firmware sends. The Hydrapool README does not document a required password for Stratum.

Then watch your Grafana, if you started it, and the pool log. A worker that appears there is a worker the server accepted. It is not yet a statement about a future coinbase.

The Foundation's donation instance ​

You are not paid

stratum+tcp://pool.256foundation.org:3333 gives hashrate to the 256 Foundation. A block found by that instance pays the Foundation, 100%. It is not a community PPLNS pool.

Hashdash, at dash.256f.org, is the stat page. Checked 5 November 2026, it tells you:

  • URL: stratum+tcp://pool.256foundation.org:3333
  • User: username.workername
  • Username: a Nostr npub, an X handle, or a website token
  • Example shape: @256foundation.bitaxe-1

Do not put a Bitcoin address there and expect it to be paid. The label is how the dashboard shows your worker.

The forum about post invites a test on this host and does not restate the payout. The FAQ does. Follow the FAQ.

The host this guide does not use ​

test.hydrapool.org is named in the software README as an instance on mainnet. The README does not say who is paid. Do not point a miner there on the strength of that sentence. See Public instances.

When something fails ​

Setup talk belongs on the Hydrapool forum: Docker, the node, config.toml, solo versus PPLNS, fees, and dashboards. Bugs in the software belong as issues on GitHub. The Telegram group is the Foundation's chat. It is not the forum, and it is not a support ticket system.
