Mine test $zkhash
Your CPU and graphics card search for one very rare SHA-256 hash. Find it and 1,000 test $zkhash are added to your wallet's balance. Every 10% of the supply mined makes the next find twice as hard.

How it works
- 1
Connect
Connect UniSat, Xverse or OKX Wallet. The site only reads your public address.
- 2
Mine
Press Start. Your CPU and graphics card search for one very rare SHA-256 hash, here in your browser.
- 3
Find
When your device finds a hash, the server checks it and reserves 1,000 $zkhash for your wallet.
- 4
Mint
Pay the Bitcoin network fee for your mint from your wallet. After the payment confirms, the tokens are minted on Bitcoin and sent to you.
Recent mints
Each one is a transaction on Bitcoin that anyone can check.No mints have been delivered yet.
Questions
What does a mint cost?
Only the Bitcoin network cost of creating your mint and sending it to your wallet, which changes with network fees. There is no other fee. The exact amount is shown before your wallet opens, and your wallet shows it again before you approve. Mining itself is free.
When do I receive my tokens?
After your payment confirms on Bitcoin, your 1,000 $zkhash are minted and sent to the address you connected. This is not instant: it usually takes from several minutes to a few hours. Your find shows "Tokens sent" with a link to the transaction when it is done.
Is it safe to connect my wallet?
Connecting only shares your public address. The one thing this site ever asks you to approve is the mint payment, after you find a hash and press Mint. It never asks for your seed phrase or private key, and nobody from $zkhash will ask for them either.
How can I check that the token and my mint are real?
Everything is on Bitcoin. The deploy inscription is linked in the Token box at the top of this page, and every mint in the list above links to its transaction. A wallet such as UniSat shows your $zkhash balance under BRC-20 once your mint has confirmed.
Why does mining get harder?
The supply is fixed at 21,000,000. Each time another 10% has been mined, a hash needs one more leading zero bit, which doubles the work. The earlier you mine, the easier each find is.
Which devices work?
A computer with a graphics card in a current Chrome or Edge is by far the fastest. Mining on a CPU alone works but is much slower. Mining uses your device's power and only runs while this page is open and you have pressed Start.
Test only. Balances here are test points, not real $zkhash. Connecting only shares your public address: this page never asks for your seed phrase, a signature or a payment. Mining runs only while this page is open and you have pressed Start, and it uses your device's power while it runs.
Stay safe. The only thing this page asks your wallet to approve is the network fee for your mint, after you find a hash and press Mint. Check the amount and address in your wallet before you approve. It never asks for your seed phrase. Mining runs only while this page is open and you have pressed Start, and it uses your device's power while it runs.
