1. Get a KIIRO address

You need a KIIRO receiving address whose keys you control: the official Kiirocoin wallet is the safest choice. Avoid exchange deposit addresses for solo mining: some exchanges do not accept block rewards (coinbase).

2. Download a mining software

Miners that work with Kiirocoin on VeinPool. Only download them from their official page (links below); the fees shown are the software's own dev fee, separate from the pool fee:

T-Rex — NVIDIA · version 0.26.8 · dev fee 1 %
Windows Linux official page
SRBMiner-MULTI — NVIDIA · AMD · Intel · version 3.7.1 · dev fee 2 %
Windows Linux official page
TeamRedMiner — AMD · version v0.10.21 · dev fee 2 to 2.5 %
Windows Linux official page
GMiner — NVIDIA · AMD · version 3.44 · dev fee 1 to 2 %
Windows Linux official page
WildRig Multi — NVIDIA · AMD · Intel · version 0.51.3 · dev fee 0.75 %
Windows Linux official page

3. Start mining

Replace YOUR_ADDRESS with your KIIRO address and rig1 with your machine's name. Command for each miner (port 3650):

T-Rex

t-rex.exe -a firopow -o stratum+tcp://veinpool.fr:3650 -u YOUR_ADDRESS.rig1 -p x

SRBMiner-MULTI

SRBMiner-MULTI.exe --algorithm firopow --disable-cpu --pool veinpool.fr:3650 --wallet YOUR_ADDRESS.rig1

TeamRedMiner

teamredminer.exe -a firopow -o stratum+tcp://veinpool.fr:3650 -u YOUR_ADDRESS.rig1 -p x

GMiner

miner.exe --algo firo --server veinpool.fr:3650 --user YOUR_ADDRESS.rig1

WildRig Multi

wildrig.exe --algo firopow --url stratum+tcp://veinpool.fr:3650 --user YOUR_ADDRESS --worker rig1 --pass x

On Windows, paste the line into a .bat file inside the miner's folder; on Linux, start the program with ./ followed by its name. On the Kiirocoin page above, the generator writes the full command (PowerShell, .bat, Linux, HiveOS, MMPOS) with your address and a Copy button.

Pool (PPLNS) or SOLO?

PPLNS pool: everyone's hashrate is combined and each block is split according to the work each miner really did. Steady income, recommended for most rigs.

SOLO: your rig mines alone; when it finds a block it receives the reward (18.3 KIIRO) minus the 1% pool fee. On a small network like Kiirocoin, a single machine can find blocks regularly; the calculator shows your exact odds.

For farms, port 3651 (PPLNS) starts at a higher difficulty: fewer shares to send, same earnings.

How much can you earn mining Kiirocoin?

Earnings depend on your hashrate, the network difficulty and the KIIRO price. The Kiirocoin calculator estimates them live (pool and solo); electricity cost is optional. The hardware ranking compares GPUs and CPUs.

Common problems

Antivirus deletes the miner: most antivirus software flags mining tools. Only download them from their official page (links above), then add an exclusion for their folder.
No stats on VeinPool: check the address, port and hostname; stats appear after the first shares (1 to 2 minutes).
Hashrate lower than expected (GPU): update your graphics driver and close apps that use the GPU (games, browsers playing video).
