sardene.

Download. Pick who gets it. Press start.

Sardene is a small, open-source app that mines Monero on your computer and sends the proceeds to a cause you choose — a creator, a project, or your own wallet. No account. No KYC. No platform holding the funds. You set the speed, press start, and the mining pool pays them directly. Sardene never touches the money.

Windows — Setup .exe macOS — .tar.gz

Android — paused. Most phones earn under 1.5¢/day, which isn't worth your battery. Back when the math works.

Linux: the button copies the install command — paste it in a terminal and you're done.
(manual bundle: .tar.gz or .zip)

1 Download & open

Pick your OS above and open the app. No install wizard, no signup.

2 Pick who gets it

Paste a Monero address or a creator's Sardene link — or mine to your own wallet.

3 Press start

Choose light, normal, or max. The miner runs until you stop it. That's the whole setup.

Are you a creator? One dedicated fan running Sardene on normal mode can be worth the same revenue as thousands of ad views — without ads or a credit-card ask. Get your one-click link and embed badge ›

What it is

Most donation tools sit between you and the recipient. Sardene doesn't. The app runs a standard Monero miner (xmrig) on your machine, sends the work to a mining pool, and the pool pays the recipient's wallet directly. Sardene itself never touches the money.

You can mine to any public Monero address, or point the app at a web page that declares its address:

<meta name="sardine:address" content="...">

The app reads the address from the page, confirms it with you, and starts mining. When you close the app, the address is gone from memory. Nothing is stored on our servers because there are no servers in the donation path.

How to use it

Download and install the app for your OS.
Paste a Monero address, or enter a URL that declares one.
Pick a CPU preset: light, normal, or max.
Press start. The miner runs in the background and stops when you tell it to.

That's it. No signup, no curated directory to browse. You can bring your own Monero address or use the optional local wallet generator inside the app. The whole point is that the choice of who to support belongs to you.

What one donor is worth

These numbers come from test machines used during development. Your fans' hardware will vary, and the XMR price moves, so the table below shows this year's range — peak, current, and minimum — at the current Monero network difficulty.

XMR price	Light · ~4.1 kH/s · ~45 W	Normal · ~8.2 kH/s · ~90 W	Max · ~12.3 kH/s · ~140 W
Peak 2026 · ~$468	~$0.14/day ~$4.20/mo	~$0.28/day ~$8.40/mo	~$0.42/day ~$12.60/mo
Current · ~$464	~$0.14/day ~$4.15/mo	~$0.28/day ~$8.35/mo	~$0.42/day ~$12.55/mo
Minimum 2026 · ~$336	~$0.10/day ~$3.00/mo	~$0.20/day ~$6.05/mo	~$0.30/day ~$9.05/mo

Assumptions: network hashrate ~5.9 GH/s, block reward ~0.6 XMR, 720 blocks/day. Power draw depends on the CPU. Donors pay their own electricity; creators receive the mined XMR. Daily values are gross proceeds, not profit.

What a community adds up to

Most people will not run max 24/7. The table below mixes realistic usage patterns at the current XMR price. Multiply or divide by roughly 1.4× to see the peak-to-minimum range for 2026.

Donor pattern	Effective daily value	100 donors	1,000 donors	10,000 donors
Casual · light · 4 hrs/day	~$0.023	~$69/mo	~$690/mo	~$6,900/mo
Regular · normal · 8 hrs/day	~$0.093	~$279/mo	~$2,790/mo	~$27,900/mo
Dedicated · max · 16 hrs/day	~$0.28	~$840/mo	~$8,400/mo	~$84,000/mo

These are gross mining proceeds, not profit. They do not include electricity, hardware wear, or pool fees. They will move with the XMR price and network difficulty. Treat them as order-of-magnitude planning numbers, not a guarantee.

Hardware care

Mining makes your CPU work hard. It will run hotter and louder than normal, and sustained heat shortens the life of any machine. Before you start:

Clean your fans and vents. Dust is the single biggest reason laptops and desktops overheat. Blow it out first.
Check that your fans work. A stuck fan can turn a warm machine into a damaged one in minutes.
Use it on hardware you own and can afford to wear. Running a CPU at full load 24/7 is not free. Expect higher electricity bills and some reduction in component lifespan.
Don't mine on shared, work, school, or public machines. That is not what this tool is for and it can get you fired or prosecuted.
Start with light. If your machine gets too hot or loud, stop. A donation tool should not destroy the donor's computer.

If a machine feels unusually hot, starts throttling, or the fan sounds wrong, stop mining and fix the cooling before continuing.

Protocol, not platform

Sardene is a reference implementation of a simple protocol: a page declares a wallet address, and a local app resolves that address and donates compute to it. We don't run a directory, we don't hold wallets for creators, and we don't approve causes. We ship the software. Creators publish their own addresses. Donors decide who to mine for.

If you want the full technical picture — identity, capability tiers, contribute-to-use, and the security model — read the whitepaper.

Adjacency policy

Sardene is the rail, not the mall. The core project publishes open-source software that lets people donate compute directly to a wallet address. That is all it does.

Other ideas — curated directories, fiat cash-out services, creator portals, marketplaces, token layers, exchanges — are welcome to exist, but they must be separate projects. They may be mentioned in Sardene documentation. Sardene does not vet, endorse, or take a cut of any of them.

This boundary is not mistrust. It is the shape that keeps Sardene from becoming a platform that can be captured, regulated into a corner, or turned against the people using it. Build around it, not inside it.

License and terms

The reference implementation is released under the AGPL-3.0-only license. By using the app or this site you agree to the Terms of Use and Privacy Policy.

Sardene does not custody funds, vet recipients, or guarantee mining outcomes. Mining uses electricity and generates heat and noise. Use it on hardware you own and at your own discretion.
