Fallback pool check

Check the User field in your fallback slot

Your miner mines on its fallback pool whenever the primary one stops answering, and it mines there with whatever is in that slot's User field:

• Your own Bitcoin address — a block found there pays you.
• The placeholder replace-this-with-your-btc-address.bitaxe — not an address, so no pool can pay it: those hours hash for nobody.
• A factory default address such as bc1qnp980s5fpp8l94p5cvttmtdqy8rvrq74qly2yrfmzkdsntqzlc5qkc4rkq — a real address that is not yours: rewards go to someone else.

Nothing you paste here is stored or sent anywhere.

Where to find it

AxeOS 2.15 and later (Bitaxe)

1. Open Pool in the menu.
2. Under Active Pool Selection, see which pool the Fallback Pool list points at — it reads like Pool 2: solo.ckpool.org (SV1).
3. Under Pool Configurations, open that pool and read its User.
4. Fix it if it is not your address, press Save, then Restart.

AxeOS also warns at the top of that page when any pool still has the factory address: “You are using the default factory Bitcoin address.”

AxeOS 2.9 to 2.14

1. Open Pool, scroll to Fallback Pool Configuration and read User.
2. Press Save, then Restart.

AxeOS 2.6 to 2.8

1. Open Pool Settings and find the field labelled Fallback Stratum User: — that is the one to read.
2. Press Save, then Restart.

AxeOS 2.3 to 2.5

1. Open Settings and find the field labelled Fallback Stratum User: — that is the one to read.
2. Press Save and restart the miner.

NerdQAxe firmware 1.1.0

1. Open Settings and find Stratum Settings.
2. With Pool Mode on Failover (Primary/Fallback), open the Fallback Stratum Pool (SV1) tab and read Username.
3. Press Save, then Restart.

Labels as they appear in the firmware source: bitaxeorg/ESP-Miner v2.15.1 main/http_server/axe-os/src/app/components/pool/pool.component.html; the same file at v2.9.0–v2.14.2 and v2.6.0–v2.8.1; components/edit/edit.component.html at v2.3.0–v2.5.0; shufps/ESP-Miner-NerdQAxePlus v1.1.0 pages/edit/edit.component.html with assets/i18n/en.json. The factory address is DEFAULT_BITCOIN_ADDRESS in ESP-Miner v2.15.1 pool.component.ts and every board's config file.

What to put there

• Stratum Host and Stratum Port: any second pool works, including your factory default — what matters is that it is a different pool from your primary.
• User: your-address.backup — your own Bitcoin address, then .backup as the worker name, so you can see which slot a share came from.
• Password: anything, for example x.

If the second pool is SoloLuck

Status as reported to /api/public when this page loaded. SoloLuck has not found a Bitcoin block.
