How to mine QRL (Quantum Resistant Ledger) on SmoozyPool

Q: Which -a flag does XMRig need for QRL?

-a rx/0. The stratum on port 3341 does not send an algorithm name with its jobs, so XMRig has to be told; it is also the flag used in the pool's Start Mining section.

Short answer: QRL is mined with RandomX, so you mine it on a CPU with XMRig (the pool also lists the Antminer X5/X9 RandomX ASICs as compatible). Run xmrig -a rx/0 -o stratum+tcp://smoozypool.es:3341 -u YOUR_QRL_ADDRESS -p WORKER_NAME -k with your 79-character QRL address, which starts with Q0. Port 3341 splits every block the pool finds among the miners in that round, charges a 1.5% fee and pays balances of 0.5 QRL or more in a payment run every 30 minutes.

What you need before you start

Hardware: QRL uses RandomX, a proof-of-work algorithm optimized for general-purpose CPUs. The RandomX authors list requirements for efficient mining that include a 64-bit CPU with hardware AES (AES-NI on x86, Cryptography extensions on ARMv8), support for large memory pages and at least 2.5 GiB of free RAM per NUMA node (fast mode uses a 2080 MiB dataset). The pool also lists the Bitmain Antminer X5 and X9 RandomX ASICs as compatible.
Wallet: your own QRL address. It starts with Q0 and is 79 characters long (Q followed by 78 hexadecimal characters). On port 3341 the stratum checks the length and checksum at login and refuses a malformed address, so copy it from your wallet rather than typing it.
Miner: XMRig, XMRigCC or SRBMiner-Multi — the three CPU miners the pool's command generator offers for QRL. Download links for XMRig and SRBMiner-Multi are on Miner Downloads.

Step-by-step: QRL mining setup with XMRig

Download XMRig from its official GitHub release page (linked on Miner Downloads).
Open the Mining Command Generator, choose QRL — Quantum Resistant Ledger · RandomX · CPU / ASIC (Antminer X5/X9), select PPLNS (port 3341), paste your address and name your worker.

Copy the command. Reference commands (on Windows the binary is xmrig.exe):

# XMRig — shared rewards, port 3341 (worker name goes in -p)
xmrig -a rx/0 -o stratum+tcp://smoozypool.es:3341 -u YOUR_QRL_ADDRESS -p WORKER_NAME -k

# Antminer X5 / X9 — pool settings in the ASIC web UI (port 3341)
Pool URL:  stratum+tcp://smoozypool.es:3341
Username:  YOUR_QRL_ADDRESS
Password:  WORKER_NAME

Keep -a rx/0: the stratum on port 3341 does not send an algorithm name with its jobs, so XMRig has to be told. On port 3341 a number after a dot (YOUR_QRL_ADDRESS.50000) pins a fixed share difficulty instead of naming a worker.

Run it. No difficulty flags are needed. On port 3341 VarDiff starts at 5,000, aims for one share every 120 seconds, retargets every 60 seconds and stays between 100 and 10,000,000. Once VarDiff has settled, a worker on port 3341 therefore sends about 30 shares an hour, and such a low share rate is expected.
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., Effective 1h (the accepted-share-weighted rate), Accepted 24h and Last Seen.

QRL on SmoozyPool — pool facts

Parameter	Value
Algorithm	RandomX (XMRig flag `-a rx/0`)
Stratum, shared rewards	`stratum+tcp://smoozypool.es:3341` (Lauterbourg, France)
Reward method, port 3341	each block's reward is split in proportion to the shares miners submitted in that block's round (the pool's API labels this port PPLNS)
Pool fee, port 3341	1.5%
Minimum payout, port 3341	0.5 QRL
Payments, port 3341	payment run every 30 minutes; a block's reward is credited once the block is 60 blocks deep
VarDiff, port 3341	starts at 5,000 · one share per 120 s · retarget every 60 s · range 100 – 10,000,000
Blocks found, shared-rewards pool	663 confirmed, 29 orphaned; last block 2026-09-16 11:54 UTC (snapshot 2026-09-16 17:20 UTC)
Pool hashrate	24.60 KH/s 24-hour average from 3 workers on 1 wallet (snapshot 2026-09-16 17:20 UTC)

Is QRL still worth mining on a CPU in 2026?

That depends on your electricity price and the QRL price, so this page gives no profitability figures. Network difficulty was 4,457,877,768 at the snapshot. On port 3341 every block the pool finds is split among the miners who submitted shares in that round, so rewards are credited block by block. Check the current round on the dashboard before deciding.

Where to sell mined QRL

As of 2026-09-16, mining-scan.com/sell/qrl lists no venue-confirmed sell route for QRL yet — the directory states that this means no route has been confirmed, not that QRL cannot be sold.

FAQ

Which port do I use for QRL on SmoozyPool?

Port 3341 on smoozypool.es. Every block the pool finds is split by the shares miners submitted in that round, after a 1.5% pool fee; balances of 0.5 QRL or more are paid automatically.

Which -a flag does XMRig need for QRL?

-a rx/0. The stratum on port 3341 does not send an algorithm name with its jobs, so XMRig has to be told; it is also the flag used in the pool's Start Mining section.

What does a QRL wallet address look like?

It starts with Q0 and is 79 characters long: Q followed by 78 hexadecimal characters. On port 3341 the pool checks the length and checksum at login and rejects a malformed address.

Why does my QRL hashrate take a while to show up?

On port 3341 VarDiff aims for one share every 120 seconds, so once it has settled a worker sends about 30 shares an hour and the hashrate estimate builds up slowly; the pool FAQ notes hashrate can take 10–15 minutes to appear. If nothing shows, check the port, the address and the -a rx/0 flag.

What is the minimum QRL payout and how often are payments sent?

On port 3341 the minimum payout is 0.5 QRL. A payment run happens every 30 minutes, and a block's reward is credited once the block is 60 blocks deep.

Can I mine QRL with a GPU?

RandomX is optimized for general-purpose CPUs, and the pool's Start Mining section lists only CPU miners and the Antminer X5/X9 ASICs for QRL, no GPU miner.
