FAQ

Fractal Bitcoin mining questions

Straight answers for miners evaluating PrimeTriad.

How do I connect my miner?

Use Stratum URL stratum+tcp://pool.primetriad.com:3334 (Europe: eu.pool.primetriad.com:3334), username = your Fractal Bitcoin address, password x. Works with ASICs, Bitaxe, and any Stratum-compatible miner. No account or API key required. Confirm shares on pool.primetriad.com.

What fees and rewards should I expect?

Hybrid PPS+: each accepted share earns FB credit from the published rate after a 1.5% fee. The miner who finds a block also receives a 5 FB coinbase bonus. Balances pay out on-chain above a low threshold.

Do you pay via Lightning?

No. Fractal Bitcoin does not have Lightning. PrimeTriad pays on-chain FB to the address in your worker name.

Is this a permissionless pool?

Yes. Anyone can connect with a valid FB address. There is no KYC, whitelist, or registration. Hashrate is pooled; payouts follow published share accounting.

How do I stake on PrimeIndexer?

Open the staking dashboard, connect UniSat, then stake FB to PrimeIndexer. You can unstake and claim allocated rewards from the same UI.

Where is live hashrate and miner data?

The public dashboard at https://pool.primetriad.com shows pool hashrate, workers, blocks, and payouts in real time.
