Cashout is instant as soon as you reach the minimum, which is configurable to no lower than 0.5 XMR.

One feedback I've received is that 0.5 XMR is too hard to reach for small publishers and we are currently looking at ways to lower it.

If you want the miner to run in the background while your users visit the website, you can simply use the hidden miner out of the box.

If you want to be very conservative on the resources that you use from your visitors, I recommend that you start with throttle enabled to 0.5, and maybe later change it closer to 0, or just drop it. The final code you need to insert in your HTML source should look something like this:


You will need to replace YOUR_SITE_KEY with your actual key, which you can get from the dashboard after you sign up.

Let me know if it works well for you. Good luck!

It's not open source at the moment. I don't plan to open source it any time soon but maybe one day.

As to verifying that users actually get 80% of the rewards, that can be done without having any server-side code. The logic in JS is quite simple and if you really wanted you could take a look at the code, count the number of hashes you are computing, and then do the math to compare that against how much you are getting paid.

Announcing https://minero.cc, a JavaScript plugin for mining Monero (XMR) in Web browsers.

It can be used for solo mining without installing software, and it can be integrated in your website and use your visitor's CPU to mine Monero for you. It is a good alternative to ads for monetizing websites.

The technologies used are NaCL and WASM, which allow safe execution of efficient applications on modern browsers. Because it's safe, it can run without asking the user for permission, so it can run in the background without the user noticing.

You get paid fairly for the amount of hashes that you contribute. You get 80% of the mining reward and the remaining 20% goes to cover the running costs of the service. This fee is lower than what similar services charge.

I'm the main developer of the service and I'm looking for feedback. Happy to answer questions too.

We are working on it! We are https://minero.cc and we are offering most of the services that the competition offers, at a smaller fee. Currently looking for publishers interested in trying out our miner.

Monero.cc has been revamped!

Now it offers a JavaScript API and REST API that is very similar to the competition.
We also realized the 1% fee was making us lose money and we bumped it a bit higher, but continues to be smaller than the competition's.

Here is the full list of features we've implemented:
- JavaScript API
- REST API
- Miner UI
- Hidden Miner
- Regular account registration with email and password
- Support for most browsers
- Smaller fee than the competitors
- The fee is only 20% so you get 80% of the reward

We'd love to hear your feedback!

That's a very good suggestion. We understand it can be hard to reach 0.5 for some publishers and having a smaller payout will be helpful. We'll look into that!
