How privacy layers make blockchain work for regulated finance
Hyli is now a privacy layer in private mainnet: production-ready infrastructure for partners building private, compliant financial applications.
Blockchains are excellent audit rails because they are radically transparent. For regulated finance, that default is a dealbreaker. If balances, counterparties, and payment patterns are public, institutions cannot use the system.
A privacy layer resolves this issue. Sensitive data stays confidential by default, while regulators get transparency on demand through selective disclosure.
Transparency breaks regulated finance
Finding the right balance for transparency
Public chains treat financial activity like a public feed. That works when the asset is meant to be fully transparent, but it breaks down when the flow is regulated.
Transparency leaks strategy. If the market can see who is about to trade, when, and with whom, it can trade ahead or adjust pricing. When balances and holdings are visible, counterparties can infer exposure and negotiate against you.
Transparent payment patterns can also expose personal information. Verizon’s 2025 DBIR analyzed 12,195 confirmed data breaches in a single year. A salary payment, a medical reimbursement, or a donation can become legible from context. Once it is on a public chain, it is permanent.
But transparency is not the enemy. Transparency creates trust and supports open markets. What this really means is that regulated finance needs a system that can be private by default, and still provably compliant.
Blockchain transparency in the European Union
The European Union is pushing on both sides of the same constraint: GDPR raises the bar for privacy by design while MiCA raises the bar for oversight and auditability.
Regulators need the ability to inspect and reconstruct what happened. This is why privacy has to be engineered at the rail level, not added after the fact.
And blockchain transparency is not a far-future need anymore: as of February 2026, a consortium of 10 major European banks is working toward a euro stablecoin launch under the name Qivalis.
Understanding privacy layers
A privacy layer is settlement infrastructure that keeps sensitive financial and personal data confidential, while still enabling compliance and audit through cryptographic proofs and selective disclosure.
A privacy layer focuses on privacy by default, transparency on demand. Data stays private in normal operations. When an issuer, an auditor, or a regulator needs to verify something, they can request and access the minimum disclosure required for that specific check.
A privacy layer is not obfuscation. It is mathematically proven privacy.
You can contrast privacy layers with:
- Privacy coins: confidentiality without selective access.
- Permissioned chains: access control without open verifiability.
What makes Hyli a privacy layer
Hyli is designed to make privacy and compliance compatible.
It uses a simple execution model:
- Off-chain execution keeps sensitive data off the public ledger.
- On-chain proofs provide public verifiability without exposure.
- Proof-based compliance supports regulated workflows (KYC/KYB, eligibility, transfer rules) without leaking user data.
Two outcomes matter most for regulated finance.
First, atomic settlement (DvP). Delivery versus Payment means the asset moves only if the payment moves, and vice versa. This reduces partial settlement risk, and the downstream credit exposure and reconciliation work it creates.
Second, traceability without public exposure. Institutions and regulators need audit trails. They need to answer basic questions like “who owned what, when?”, and “did this transfer follow the rules?”.
On Hyli, this is handled through selective disclosure. Sensitive details stay confidential by default. When an issuer, auditor, or regulator needs to verify a specific flow, they can request the minimum information required for that check, without turning the whole ledger into a public dataset.

What comes next for the Hyli privacy layer
Hyli is in limited access mainnet. We are production-ready for partners building private, compliant financial applications.
Today, the most relevant partners are licensed stablecoin issuers, tokenization platforms, and financial institutions that need confidentiality without giving up auditability.
If you are building in that category, here are three concrete use cases we are focused on:
- MiCA-aligned private stablecoins (EUR-first)
- Private tokenized assets settlement
- Confidential B2B payments
