Cardinal pilots help selected organisations validate pre-transaction protection and risk-routed settlement in a controlled environment before wider production adoption. A typical design-partner pilot runs for 60–90 days and focuses on one clearly defined transaction flow, a limited group of users, explicit networks and assets, measurable success criteria, and documented operational controls.
A Cardinal pilot is not approval for unrestricted production use. SafeSend is currently a controlled Arbitrum Sepolia testnet MVP. Programmable Escrow remains in final testing and security hardening. The Protection API does not replace KYC, KYB, AML, sanctions, custody, legal, licensing, or regulated-escrow processes.

Who the programme is for

The programme is designed for organisations that can provide a real workflow, an accountable implementation team, and structured feedback.
  • Wallet and exchange providers
  • Custodians and vault platforms
  • Stablecoin and payment companies
  • RWA and tokenisation platforms
  • UAE real estate brokers and developers
  • OTC desks and enterprise treasury teams
  • Luxury vehicle, yacht, and private-aviation businesses
  • Other businesses processing high-value digital-asset payments

Recommended starting point

Start with one real high-value customer workflow and one wallet, exchange, or digital-asset platform integration. Keep each pilot narrow enough to measure clearly.

Pilot outcomes

Every pilot should answer five questions:
  1. Can Cardinal be integrated into the selected workflow safely?
  2. Does pre-transaction decisioning improve the handling of risky or incorrect intents?
  3. Can the partner operate ALLOW, REVIEW, BLOCK, error, and unavailable outcomes consistently?
  4. Can the transaction, decision, approval, and settlement evidence be reconciled?
  5. Is there a justified path to a production commercial agreement?
The pilot is complete only when technical results and the partner’s security, compliance, operational, and commercial acceptance criteria have been reviewed.

Onboarding phases

Phase 1: qualification

Cardinal and the prospective partner confirm:
  • The transaction or payment workflow
  • The business problem and current control gap
  • Expected transaction volume and value range
  • Target network, asset, wallets, and contracts
  • Required decision and approval points
  • Named business, technical, security, compliance, and operational owners
  • Product capabilities required for the pilot
  • Legal, regulatory, custody, and data-protection dependencies
  • Target launch window and resource availability
Avoid pilots that depend on unverified roadmap features or an unrestricted production deployment. Narrow the scope until it can be supported and tested safely.

Phase 2: scope and controls

Create a written pilot plan before integration begins.

Pilot definition

Document:
  • Partner name and pilot owners
  • Selected use case and user journey
  • Included and excluded products
  • Network, token, transaction type, and value limits
  • Number and type of pilot users
  • Approved sending, receiving, and contract addresses
  • Pilot start, review, and end dates
  • Commercial terms and conversion decision

Decision policy

Agree how every outcome will be handled. The partner’s policy may be stricter than Cardinal. A pilot must never weaken a BLOCK result.

Responsibility matrix

Phase 3: technical setup

Environment

Use separate pilot credentials and an approved non-production or limited pilot environment.
  • Keep the Cardinal API key behind the partner backend.
  • Store secrets in an approved secret manager.
  • Restrict access using least privilege.
  • Do not copy production secrets or unnecessary personal data into the pilot.
  • Confirm supported network and asset identifiers.
  • Confirm exact smart-contract addresses from an approved source.
  • Use test assets where the selected product is not production-ready.

Integration

The partner should:
  1. Build the final canonical transaction intent.
  2. Submit it to the Protection API from a trusted backend.
  3. Store the Cardinal request_id, decision, findings, and intent hash.
  4. Apply the agreed decision policy.
  5. Bind user confirmation and approvals to the checked intent.
  6. Verify that the signed or settled transaction matches the intent.
  7. Reconcile the final blockchain result.
Read the Integration Guide and Security Best Practices before implementation.

Data minimisation

Submit only the transaction fields required for the check. Do not send private keys, seed phrases, authentication secrets, identity documents, confidential contracts, title documents, or unnecessary personal information.

Phase 4: validation

Complete the agreed test plan before the controlled launch.

Required decision tests

  • Valid low-risk intent
  • First-time or changed recipient
  • Wrong network
  • Changed token or amount
  • Changed contract or permission scope
  • REVIEW handling
  • BLOCK handling
  • Invalid request
  • Authentication failure
  • Rate limit response
  • Timeout and unavailable service
  • Duplicate submission or retry
  • Checked-intent and signed-transaction mismatch

Product-flow tests

Where applicable, test:
  • SafeSend creation, funding, protection window, cancellation, claim, and expiry
  • Escrow creation, funding, approval, release, refund, cancellation, expiry, milestone, and denied state transitions
  • Wallet connection and network switching
  • Additional or multisignature approvals
  • Evidence and reconciliation records
Only test features included in the signed pilot scope. Escrow testing does not establish that a deployment is audited, licensed, regulated, or production-ready.

Readiness review

Before launch, both parties should confirm:
  • Test cases pass or have approved limitations.
  • Pilot users and approvers are trained.
  • Value, asset, network, and address limits are enforced.
  • Monitoring and escalation contacts are active.
  • Incident and credential-rotation procedures are documented.
  • Support hours and response expectations are understood.
  • Legal, compliance, security, and operational approvals are recorded.

Phase 5: controlled launch

Begin with the smallest useful cohort and transaction value.

Launch controls

  • Named pilot users only
  • Explicit transaction and daily value limits
  • Approved networks, tokens, destinations, and contracts
  • Manual handling for REVIEW
  • No bypass for BLOCK, timeout, or unavailable outcomes
  • Dual approval for high-value or release actions where required
  • Daily reconciliation during the initial launch period
  • A documented pause procedure
Expand the pilot only after the current stage meets its acceptance criteria.

Operational rhythm

A practical pilot cadence includes:
  • Launch-day monitoring
  • Weekly technical and operational review
  • Decision-quality and incident review
  • Open issue and remediation tracking
  • Mid-pilot scope and success-metric review
  • Final outcome and conversion meeting
Material scope changes should be documented and approved. A new network, asset, product, or transaction type may require a separate validation cycle.

Success metrics

Agree baselines, targets, data sources, owners, and review dates before launch. Do not claim fraud-loss reduction without a defensible baseline and verified outcome data.

Evidence record

Maintain an append-only pilot evidence record containing:
  • Pilot and business transaction IDs
  • Canonical intent and intent hash
  • Cardinal request_id, decision, findings, and timestamp
  • Partner policy result
  • Initiator and approver references
  • SafeSend or Escrow references where applicable
  • Blockchain transaction hashes
  • Final outcome and reconciliation status
  • Review, incident, support, and remediation references
  • Pilot limit or scope changes
Keep sensitive business, identity, and legal records in the partner’s controlled systems.

Support and escalation

Each pilot should have named business and technical contacts on both sides. Use the agreed channel for integration questions, suspected product defects, decision investigations, and service incidents. For urgent security issues, first pause the affected flow, protect credentials, preserve evidence, and follow the partner’s incident-response process. Never send a private key, seed phrase, password, authentication token, or live API key to Cardinal support.

Pilot completion

At the end of the pilot, Cardinal and the partner review:
  • Results against every success criterion
  • Confirmed product and operational value
  • Security, compliance, reliability, and user-experience gaps
  • Required remediation and owners
  • Production scope, networks, assets, values, and service expectations
  • Commercial terms and target production date
  • Whether a case study, testimonial, or public announcement is separately approved
Possible outcomes are:
  • Proceed to a production agreement
  • Extend the controlled pilot with documented objectives
  • Pause for remediation or required product readiness
  • End the pilot without production deployment
Pilot participation does not create permission to use Cardinal branding, publish results, or make security, audit, compliance, or production claims unless agreed in writing.

Onboarding checklist

  • Pilot brief and accountable owners confirmed
  • Use case, scope, exclusions, duration, and commercial terms agreed
  • Network, token, values, addresses, contracts, and users limited
  • Responsibility matrix approved
  • Success metrics and baselines documented
  • Pilot credentials issued and stored securely
  • Integration and security guidance reviewed
  • Decision, error, timeout, and unavailable paths tested
  • Product lifecycle tests completed where applicable
  • Legal, compliance, security, and operational approvals recorded
  • Monitoring, support, escalation, and incident contacts active
  • Controlled-launch approval signed off
  • Weekly review and final evaluation scheduled
