# How much does VNISH firmware cost?

> The build is FREE OF CHARGE to download and to test. There is no paywall, no licence key and no trial timer. A small share of hashrate applies only while the firmware is actually running, and it stays visible in the dashboard. On a correctly matched ASIC the extra income VNISH generates normally outweighs this share several times over.

## What the fee is and is not

- Installing costs nothing and leaving costs nothing: no installation fee, no penalty if you go back to stock - the share simply stops with the firmware.
- It is charged only for actual use, on active hashrate - not on your wallet, not on your pool balance.
- It is visible in the dashboard. Nothing about it is hidden, and you can read it at any time on a running machine.
- On a well-matched and configured ASIC, the extra income normally outweighs this small share several times over. Actual results depend on the model, operating profile and electricity price.

## Why free to test matters

Firmware claims are cheap and fleets are expensive. Take the build, run it on one machine, measure hashrate, efficiency, chip temperature and error rate against your own stock baseline, and decide from your numbers rather than from a table on a website.

## Partner terms

Mining hotels and colocation sites work through the partner program: branded firmware and a personal fee proxied to any pool. That path runs through roiasic.com.
