"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
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.
Bidirectional ranging + biological liveness at each endpoint proves the right living humans were physically present. Not device-level proximity. Not GPS approximation. Human.
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.
Typed references tie the receipt to the specific patient, item, document, trip, parcel, property, or service. Optional external-authority co-signature for regulated bindings.
Receipt verification gates downstream technical operation: hardware-backed key release, physical actuator, smart-contract settlement, billing event, legal admission.
Three value-driver categories. Coramly serves all three with the same API.
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.
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.
Higher-assurance proof-of-service records that survive affidavit challenges. For national service networks, litigation support, and insurer-preferred evidentiary tiers.
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.
Plumbers, electricians, inspectors, installers. Prove the worker was onsite with the customer for the work order's duration. Stops billing fraud; strengthens warranty disputes.
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.
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.
One link. The buyer proves they're a real, living human in your city — or the deal doesn't happen. Stop guessing. Start verifying.
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.
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.
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.
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.

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