Cryptographic privacy via Hinkal smart contract - instant execution without centralized intermediaries.
Instant and wallet-agnostic.
Each user controls confidential balances via their existing wallets, assets move between confidential balances without revealing recipient, amount, or sender. Executed under 3 seconds.
ZK-powered.
Verified without revealing balances, amounts, or counterparties.
Transactions expose:
• Recipient
• Sender
• Amount
• Balances
• History
This isn’t just transparency.
It means any counterparty can track:
• Your total balance
• Who you transact with
• How you move funds
• Your activity over time
Most solutions focus on the sender.
But payments still break at the destination.
If you can’t receive privately -
the transaction is exposed anyway.
Now, payments can happen without exposing either side:
• Recipient is not revealed
• Sender is not revealed
• Amount is not visible
How it works:
Connect any wallet → pay.hinkal.io
Enter recipient address
Select token + amount
a Choose confidential settlement
If the recipient never received a private payment:
A confidential balance is automatically created
Linked to their existing wallet
From the recipient side:
Open pay.hinkal.io and
simply connect the same wallet the sender entered as the recipient.
Access funds in a confidential balance
Hold, use, or move funds anytime -
without exposing balances or history.
This enables private payments across any flow:
• Receiving
• Paying
• Transferring
All without exposing activity
Exit to public rails anytime:
Send to any wallet as a standard transfer.
But the original payment and sender remain confidential
Privacy - with compliance built in:
• Transactions screened via Chainalysis
• High-risk addresses blocked before execution
• Viewing keys enable selective disclosure when required
And this isn’t just a product -
its infrastructure.
Wallets, apps, and protocols on Solana can add:
• Confidential balances
• Private receive
• Private payouts
Into their existing stack with minimal integration.
Not just private sending -
but payments where neither side is exposed.
