Confidential values
Amounts and balances are committed, never published. Qedis never sees, stores, or decrypts the underlying value — it stays with its owner.
Verifiable confidentiality · native to your chain
Private by design.
Private by design.
Verifiable by proof.
Qedis keeps values and data private to their owners and proves every operation correct — without ever decrypting them, without a master key anyone could compromise, and without trusted hardware. Post-quantum by design, and native to the chains you run.

The trust wedge
The confidential layer that keeps no secrets.
Other confidential-finance approaches keep a secret that, if compromised, retroactively exposes everything — a hardware master key, or a global decryption key. Qedis keeps no such secret. Confidentiality rests on public mathematics and is post-quantum by design: there is nothing to steal and no quantum expiry, and disclosure is always owner-mediated and verifiable.
Secret-holding approaches (TEE / FHE classes)
- A single secret — a hardware master key or a global decryption key
- Compromise it and all past confidentiality unwinds
- Trust rests on hardware enclaves or a threshold key
- Today’s encrypted data faces a quantum “harvest-now, decrypt-later” risk
Qedis — verifiable confidentiality
- Values are never decrypted — anywhere, by anyone but their owner
- No master key. No trusted hardware. No trusted setup.
- Security rests on public, post-quantum-by-design cryptography
- Disclosure is owner-mediated and provable against on-chain state
What Qedis is
Confidentiality you can prove — not confidentiality you have to trust.
Verifiable by proof
The network checks zero-knowledge proofs — range, conservation, membership — at consensus. It learns only valid or invalid, nothing more.
Non-custodial disclosure
When supervision requires it, an authorised party opens exactly what they’re entitled to — with an issued viewing key, verifiable against on-chain state.
Native to your chain
A substrate-agnostic runtime that runs as native execution at your chain’s consensus layer — not a contract on someone else’s network. Avalanche today; any substrate next.
How it works
Commit. Prove. Verify.
Three moves keep data private while keeping the network honest.
-
01
Commit
A value is sealed into a binding cryptographic commitment. It’s published; the value is not. Equal amounts look different on-chain.
-
02
Prove
The owner attaches zero-knowledge proofs — that an amount is well-formed, that a transfer conserves value, that a party is a member of an allow-list — authorised with post-quantum signatures.
-
03
Verify
The runtime verifies natively, atomically, at the consensus layer — accepting or rejecting the state change without the value ever being exposed.
Selective disclosure for audit and supervision is delivered separately and cryptographically: an authorised viewer opens only what a grant permits, and can verify it against the public commitment.
Capabilities
A verifiable-confidentiality toolkit for any application.
Composable building blocks — use one, or compose them into a full confidential, eligibility-gated, atomically-settled, auditor-disclosable flow.
Confidential transfers
Move tokenized assets and cash with amounts hidden, correctness proven, and supply conserved by construction.
Atomic delivery-versus-payment New 2026
Settle two confidential legs all-or-nothing: both sides complete or nothing moves. No half-settled risk.
Signature-authorized transfers New 2026
A third party can settle on your behalf without ever taking custody — authorized by your post-quantum signature.
Eligibility gating
Enforce KYC / allow-list and sanctions checks with the underlying identity kept private.
Owner-controlled disclosure
Reveal a position to an auditor or regulator on your terms, verifiable against the chain — never a shared key, never decrypted on-chain.
Composable compliance New 2026
Express auditable, bounded compliance policies that compose cryptographic checks — predictable cost, nothing decrypted.
Future-proof proofs New 2026
A configurable, upgrade-safe verification backend that can adopt newer transparent proof systems without weakening security.
Stealth accounts New 2026
One-time addresses that are themselves hidden-balance accounts — spend directly from a stealth address with range and solvency proofs in one state transition.
Watch-only supervisory keys New 2026
Auditors read the full transaction graph and amounts with zero spend authority and no master secret — structurally incapable of moving funds.
Identity-private eligibility New 2026
BBS+ credential proofs gate confidential operations — prove you meet an eligibility requirement without revealing who you are.
Post-quantum by design
Built for the NIST / CNSA-2.0 era, so today’s confidential data isn’t exposed to tomorrow’s “harvest-now, decrypt-later.”
Deploy on your own chain
A substrate-agnostic runtime — not someone else’s network you must rent. Live today on an Avalanche L1.
For institutions
Designed for the people who answer to a regulator.
Data minimisation
Keep amounts and counterparties off the public ledger by default — while still proving every transaction is valid.
Atomic settlement (DvP)
Settle confidential trades delivery-versus-payment — both legs complete or nothing moves, optionally compliance-gated before any value changes hands.
Eligibility & sanctions
Enforce KYC / allow-list membership and sanctions screening at the protocol layer, with the underlying identity kept private.
Supervisory access
Grant lawful, scoped visibility to auditors and supervisors — disclosure that is owner-mediated, cryptographic and verifiable, not a trust-me access role.
Post-quantum posture
A signature, eligibility and disclosure layer built for the post-quantum era, with a clear migration path as standards harden.
No single point of compromise
There is no master key whose breach unwinds confidentiality, and no enclave to trust. Privacy is a property of the mathematics.
