How to mine Firo (FIRO) on SmoozyPool

Short answer: Firo is mined on a GPU with the FiroPoW algorithm. Use a FiroPoW miner such as T-Rex (NVIDIA), TeamRedMiner (AMD) or SRBMiner-Multi and point it at stratum+tcp://smoozypool.es:4031 with YOUR_FIRO_WALLET.worker1 as the username (a standard Firo address is 34 characters and starts with a, rarely Z). Port 4031 is PPLNS with a 1.5% fee and a 0.5 FIRO minimum payout, paid by an automatic payout run every 2 hours; port 4034 is SOLO.

What you need before you start

• Hardware: a GPU. Firo is mined with FiroPoW, a modified ProgPoW 0.9.4 designed for GPUs; the official Firo mining guide targets GPUs with 8 GB of VRAM and above.
• Wallet: a standard Firo address: 34 characters, starting with a (rarely Z). The official Firo guide advises against mining directly to an address owned by an exchange.
• Miner: SRBMiner-Multi, TeamBlackMiner, TeamRedMiner (AMD) or T-Rex (NVIDIA; abandoned in 2022 but still works) — the set the pool's command generator offers for FIRO. lolMiner does not support FiroPoW.

Step-by-step: FIRO mining setup

1. Download the miner from its official GitHub release page (T-Rex, TeamRedMiner and SRBMiner-Multi are linked on Miner Downloads).
2. Open the Mining Command Generator, choose FIRO — Firo · FiroPoW · GPU, pick PPLNS or SOLO, paste your wallet and name your worker.
3. Copy the command (on Windows you can save it as a .bat file). Reference commands (PPLNS, port 4031; use port 4034 for SOLO):

   # T-Rex (NVIDIA)
   t-rex -a firopow -o stratum+tcp://smoozypool.es:4031 -u YOUR_FIRO_WALLET.worker1 -p x
   
   # TeamRedMiner (AMD)
   teamredminer -a firopow -o stratum+tcp://smoozypool.es:4031 -u YOUR_FIRO_WALLET.worker1 -p x
   
   # SRBMiner-Multi
   SRBMiner-MULTI --algorithm firopow --pool smoozypool.es:4031 --wallet YOUR_FIRO_WALLET.worker1 --password x

4. Run it. No difficulty flags are needed: VarDiff aims for one share every 15 seconds, re-evaluates at most every 15 seconds and keeps the share difficulty between 200,000 and 500,000,000.
5. Check your worker at Wallet Lookup. The pool FAQ notes that hashrate can take 10–15 minutes to appear. The worker table shows Live Est. (a 10-minute rolling average), Effective 1h (the accepted-share-weighted rate over the last hour), Accepted 24h and Last Seen.

FIRO on SmoozyPool — pool facts

Where to sell mined FIRO

Venue-checked routes are tracked at mining-scan.com/sell/firo. As of 2026-09-16 it listed five routes confirmed by the venue itself: FreiExchange, MEXC, Biconomy, NonKYC and Exolix. Availability changes; check the page before you send coins.

FAQ

How long until my FIRO hashrate shows on the dashboard?

The pool FAQ notes it can take 10–15 minutes. Live Est. on Wallet Lookup is a 10-minute rolling average and Effective 1h covers the last hour, so both fill in only as accepted shares arrive. If it stays at 0, check the port (4031 or 4034), the wallet spelling and the -a firopow flag.

Which server should I connect to for Firo?

smoozypool.es (Lauterbourg, France), port 4031 or 4034. Monero, Ravencoin and Zcash use their own hostnames (xmr.smoozypool.es, rvn.smoozypool.es, zec.smoozypool.es) on the pool's Montréal site; the coin card and the Start Mining section always show the right host.

Can I mine Firo with a CPU?

No. FiroPoW is designed for GPUs. For CPU mining on SmoozyPool use a RandomX coin: XMR, ZEPH, QRL or XTM (RandomX port).

What is PPLNS and why does my payout vary?

PPLNS pays each block's reward in proportion to your shares in the recent share window before that block, after the 1.5% fee. Income arrives only when the pool finds a block, so it is lumpy; SOLO on port 4034 pays only for a block your own worker finds.
