Consent infrastructure for research
Verifiable, patient-owned consent. From signature to audit.
Every consent a participant gives produces a tamper-proof receipt and a retrievable copy of the exact document they agreed to — revocable on demand, provable years later. It runs on the same infrastructure already securing patient health data in production.
What it does
A receipt for every consent. When a participant consents, the SDK records a cryptographic receipt on-chain. It carries only opaque references — a hash, a study identifier — never a name, an email, or any participant data. The consent is verifiable without exposing who it belongs to.
The document, preserved. The exact consent document the participant agreed to is encrypted and stored. Pull it back any time for an IRB or audit, and confirm it hashes to the on-chain receipt — proof it has not changed since the day it was signed.
Revocable, by the participant. Withdrawal is recorded the same way consent was — on-chain, timestamped, verifiable. The record reflects the truth at every point in time.
How it works
- The participant consents in your flow. No wallet, no crypto knowledge — one is provisioned invisibly behind the login they already use.
- A receipt is minted on-chain, sponsored. The participant pays nothing and needs no setup.
- The document is sealed — encrypted and stored, linked to the receipt by a hash.
- Verify or retrieve any time — confirm integrity, or produce the original signed document for audit.
Who it's for
CROs, study sponsors, academic research groups, and site networks that need defensible, auditable participant consent — and a record that holds up long after a study closes.
Where we are today
The infrastructure is live on Solana mainnet and already in production for patient health data. We are onboarding a small group of early partners to design the integration around real study workflows. If your team is rethinking how participant consent is captured, proven, and audited, we'd like to hear from you.

Arxova provides consent and audit infrastructure. It is not a research organization and does not conduct research or provide regulatory, legal, or IRB approval. Consent receipts contain no participant identifying information; consent documents are encrypted at rest. Integration terms and compliance scope are discussed directly with prospective partners.
