Cross-Rails Intelligence
Molecule to milestone.
Lab to ledger.
Sponsors fund each study milestone in dollars. The CRO gets paid the moment you approve with a passkey, and every payment comes with a receipt. Nothing moves without a human sign-off.
For sponsors and CROs. The sandbox does not move real money.

Example dataHow the money moves
Every dollar accounted for.
A $150,000 study, paid in three milestones: Kickoff $45,000, Interim $60,000, Final report $45,000. Example data
- 1
- 2
Step 02
Approve the milestone
A person at the sponsor approves the release. Nothing moves without a passkey. A second person confirms when the amount requires it.
Interim milestone2 of 2 approvers - 3
Step 03
Release the payment
The CRO is paid the full milestone amount. A receipt records the step.
Interim milestoneReleased $60,000
Milestone payments stay between the sponsor and the CRO. CROX keeps the receipt. CROX never holds the funds. The sandbox does not move real money.
How it works
One payment, from approval to a receipt.
Scroll the steps or pick one. The human approval is a button you have to press.

Illustration ready. Nothing here moves funds.
Two people, then a delay.
The Halcyon demo policy asks for a second approver above $50,000. This $60,000 interim milestone needs both. Final approval starts a 1-hour delay. In the app, each approval confirms with a passkey.
Human approval

Over the $50,000 threshold. Two different people.
The payment and the receipt.
The payment is released only after two human approvals, the delay, and another passkey step. The sandbox does not move real money. CROX does not hold the funds.
Who it’s for
Sponsors fund the milestone. CROs do the work.
CROX is for preclinical biotech sponsors and the CROs they hire. The names below are the fictional demo, so you can see the shape of a study without mistaking it for a customer list.
Sponsors
Preclinical biotechs
The sandbox sponsor is Halcyon Bio, a fictional organization. Scientist, approver, and admin roles share one study and one audit log.
- Fund each milestone in dollars.
- Set the policy: a threshold, a second approver, a delay.
- Approve the release with a passkey.
- Open a receipt for every step.
CROs
Labs on the study
Northbridge Preclinical, Kestrel Labs, and Arden Toxicology are fictional CROs in that same demo. A CRO sees its payments and receipts.
- Do the work on the study.
- The full milestone is paid when the sponsor approves.
- Follow a payment through the delay window.
- Open the receipt for that step.
Trust
The release waits for a person.
Policies, passkeys, and a receipt sit between an approval and a payment. CROX never holds the funds.
CROX never holds the funds
Milestone payments stay between the sponsor and the CRO. CROX keeps the receipt. It does not hold the money. The sandbox does not move real money.
A policy, not a vibe
The Halcyon demo policy asks for a second approver above $50,000 and a 1-hour delay after the final approval. Cancel during that window does not move funds.
Passkey step-up
Fund, release, policy save, and team role changes confirm with a passkey. A password is the fallback only when the account has no passkey. Once a passkey exists, the password is refused for those steps.
A receipt for every step
The fund, the release, and a later refund each have a receipt the two organizations can open. This is the record, not a certification.

A person approves the release. Nothing is funded or paid until that approval. Above the policy amount, a second person approves, then a delay runs. Each approval confirms with a passkey.
