"You can fake a photo. You can fake a voice. You can fake a location. You cannot fake a heartbeat standing two feet away from another heartbeat."

The Coramly axiom

The platform

Four primitives. One signed receipt.

Each event on your platform that requires proof of a real-world handoff can be gated by all four — or any subset. Receipts are hardware-signed on-device and verifiable offline by anyone with the public key.

01 · PRESENCE

Who was there

Bidirectional ranging + biological liveness at each endpoint proves the right living humans were physically present. Not device-level proximity. Not GPS approximation. Human.

02 · CONTINUITY

For how long

Hash-linked checkpoints spanning the shared interval. Prove uninterrupted co-presence over a duration, a route, a transaction window — not just a single-shot snapshot.

03 · BINDING

And what about

Typed references tie the receipt to the specific patient, item, document, trip, parcel, property, or service. Optional external-authority co-signature for regulated bindings.

04 · CONSEQUENCE

What unlocks

Receipt verification gates downstream technical operation: hardware-backed key release, physical actuator, smart-contract settlement, billing event, legal admission.

What it unlocks

Any event where consequence depends on who was really there.

Three value-driver categories. Coramly serves all three with the same API.

Home healthcare visitsBILLING

Verified visit completion. Cryptographically prove the caregiver and patient were physically together for the billed duration — replacing self-reported EVV logs that drive Medicaid audit exposure and family disputes.

Authenticated high-value exchangeCASH

Conditional settlement for in-person closings of watches, bullion, jewelry, collectibles, art, vehicles. Release funds only when both parties are verified present and the item is bound to the session.

Process service & legal handoffsLEGAL

Higher-assurance proof-of-service records that survive affidavit challenges. For national service networks, litigation support, and insurer-preferred evidentiary tiers.

Custody & handover workflowsLEGAL

Parent-to-caregiver, carrier-to-recipient, driver-to-passenger. Any handoff where both parties' continuity-of-presence through the transition is the legal or insurance record.

Field service & home tradesBILLING

Plumbers, electricians, inspectors, installers. Prove the worker was onsite with the customer for the work order's duration. Stops billing fraud; strengthens warranty disputes.

Real-estate showingsLEGAL

Agent-safety and transaction documentation. Tamper-evident record of who the agent was with, where, and for how long — surviving disputes, deal fallouts, and post-event complaints.

For humans, too

The same physics that gates a Medicaid claim ends a catfish.

Coramly is the SDK behind consumer apps that need one thing the internet has never offered: undeniable proof that a real, living person is exactly where they say they are — without surrendering who they are.

MARKETPLACE · GREED & FEAR

Selling a $2,000 MacBook? Don't meet a burner profile. Demand an Aura Check.

One link. The buyer proves they're a real, living human in your city — or the deal doesn't happen. Stop guessing. Start verifying.

STATUS · THE FLEX OF REALITY

Tired of AI bots and catfish? Put your Aura Verification link in your bio.

The ultimate flex of reality. A hardware-sealed receipt that the human behind the handle is, in fact, human — and exactly where they claim to be.

SAFETY · NO SURVEILLANCE

Prove you're safe to your family. Without being on a map 24/7.

Sentinel mode publishes a signed proof-of-life heartbeat to the people who love you. GPS coordinates only release on a duress trigger. Privacy and protection, finally on the same side.

Building one of these? The Coramly SDK is the verification primitive — you ship the consumer brand.

How it works

A signed receipt, verifiable offline.

Your mobile app (or ours) captures the four primitives during an event. The receipt is signed inside the device's Secure Enclave / hardware-backed Keystore using a non-extractable key. Your backend — or any third party — verifies the receipt with the device's public key. No centralized trust required.

Example: home-health visit

A caregiver and patient are verified as physically co-located for the visit duration. The visit is bound to the patient's EVV ID and a service code. The receipt can be presented to the MCO billing system, an insurer audit, or a family-dispute reconciliation with cryptographic integrity — no manual review required.

The receipt format is W3C Verifiable Credential-compatible. Signature schemes: ECDSA P-256 via Apple Secure Enclave, Android StrongBox, or Ed25519 via TPM on desktop.

Privacy & security

On your device. Hardware-rooted. Identity-optional.

Designed from day one for healthcare, legal, and financial workloads. No central database of events. No cloud dependency for verification.

Hardware-signed on-device
Signing keys are non-extractable from Apple Secure Enclave / Android StrongBox. No server ever sees them.
Biological data never uploads
Motion and physiological signals are processed in the device's secure enclave. Only signed attestation tokens leave.
Offline-verifiable
Any party with the public key can verify a receipt without a network round-trip to Coramly.
Identity-optional disclosure
Zero-knowledge proof mode lets you prove the event happened without revealing the participants' identities.
W3C Verifiable Credentials
Receipts are standard VCs. Integrate with existing credential-aware systems without custom parsing.
HIPAA-ready architecture
BAA-ready data model. Healthcare bindings support external-authority co-signatures from hospital enterprise keys.

Stop guessing. Start verifying.

If your platform releases money, underwrites risk, creates a legal record, or asks users to trust a stranger — you have a problem Coramly solves. Profiles lie. Physics doesn't.

Private beta. Design partners prioritized.
