Every on-chain payment exposes your balances, history, and treasury flows in real time. Counterparties and competitors use this against you - weakening your leverage and edge.

How It Works
Confidential settlements,
payments & payouts
Connect your wallet
Connect any wallet to move funds, settle, or receive payments on a private balance. Your keys, your custody
Move funds privately
Funds arrive on a private balance inside Hinkal smart contract, controlled via your existing wallet.
Keep existing workflows
From there, you can execute private to private transactions or move funds to any public address. All without changing wallets, chains, stables or compliance controls
Technology
Institutional-grade privacy.
How it works under the hood.
Built on zero-knowledge proofs with compliance screening baked in from the start.
Confidential balance
When settlement is executed, funds move into a confidential balance accessible by the recipient's existing wallet. What appears on-chain is an interaction with a Hinkal smart contract.
Public wallet as control mechanism
Recipients don't need a new wallet. Their existing public address is the key that authenticates access to their confidential balance. No migration, no setup — connect the same wallet they already use.
Zero-knowledge proofs
Before any transfer is processed, ZK technology verifies sender balance, transaction uniqueness, and recipient validity — without exposing any underlying data.
Compliance screening
Before execution, every transfer is screened through Chainalysis KYT. High-risk addresses are prevented from interacting with the Hinkal smart contract.
Selective disclosure
Viewing keys allow users to selectively disclose transaction history to auditors and regulators when legally required — confidentiality without sacrificing accountability.
use cases
Built for real-world confidential flows
Hinkal Pay is used across industries that require financial discretion in on-chain operations.
What stands out about Hinkal is its intuitive UX - privacy without trade-offs or behavior changes. It integrates seamlessly into existing workflows, making privacy accessible, frictionless, and closer to how it should exist at the protocol level.

Hinkal solves one of the hardest problems - privacy without sacrificing compliance. Viewing keys, selective disclosure, and KYT create a framework where institutions can operate confidently on-chain.

Bringing private payments to the Polygon wallet required a privacy layer we could trust at the infrastructure level. Hinkal brings the cryptographic rigour and compliance-first design that serious payment flows demand. It's a strong foundation for what we're building next

Privacy will define the next phase of blockchain adoption. Hinkal stands out by combining strong tech, usability, and compliance - making it not just relevant, but foundational for real-world use.

Thanks to Hinkal, we’ve taken privacy to the next level - integration of their solution into our dashboard allowed our users to enjoy seamless private transactions on their favorite chains.
Jason Li

We tested several privacy solutions, but Hinkal stood out in both capability and ease of integration. Their SDK is straightforward, and the product delivers full sender/recipient privacy across multiple chains - which is hard to achieve.

We backed Hinkal because they’re solving a critical gap - scalable, compliant privacy. The team combines strong technical depth with a clear vision, positioning their infrastructure as core to the future of on-chain finance.

Hinkal fits naturally into our execution layer as a privacy component. It enables confidentiality without breaking composability - which is critical for modern, complex on-chain systems.

Hinkal was the only solution that let me add private execution to Aave without rebuilding everything. The SDK is simple, reliable, and production-ready - letting me focus on the product, not infrastructure.
