Enterprise transaction controls

Control digital asset transactions before they become irreversible.

Cardinal combines transaction intelligence, business policy and protected settlement to produce explainable ALLOW, REVIEW or BLOCK decisions before a business accepts, sends or settles supported digital assets.

The problem

Payment risks can be difficult
or impossible to reverse.

A digital wallet is designed to hold and send assets. Cardinal adds payment checks and business rules before a transaction is approved.

Excessive permissionAn approval may give an application wider access than intended

Changed recipientMalicious software may replace a copied payment address

Wrong networkA payment sent on the wrong blockchain may not reach its intended destination

Long-lived approvalA permission may remain active well beyond the current payment

Limited recoveryA completed blockchain payment may be impossible to reverse

The wrong permission, address or network can create a loss that is difficult to recover.

Protection Engine

Checked before your team
approves the payment.

Cardinal evaluates the available payment, address and network information before the business accepts, sends or settles the payment.

The verdict

Clear decision.
Clear reason.

Available evidence and the organisation's rules produce an ALLOW, REVIEW or BLOCK result, with uncertain cases directed to an authorised person.

DECISION: LOW RISK · PROCEED

SafeSend

Time to review
before settlement.

Testnet funds are held for a defined period, giving the sender time to cancel before release.

Payment check and decision before funds are locked

Defined cancellation window from 15 minutes to 72 hours

Recipient can view the pending transfer but cannot release it early

Cancellation returns the transferred amount; network fees are not refundable

Escrow · Arbitrum Sepolia testnet

Conditional settlement
with a clear record.

Testnet funds are held by smart-contract rules while both parties complete the agreed transaction.

Fund

Buyer places testnet funds into escrow

Seller accepts the agreement

Complete

Both parties complete the agreed transaction

Settle

Funds are released or refunded by the recorded status

Cardinal Intelligence · pilot layer

Evidence with a source
and date.

Cardinal is being designed to organise available provider, public and product evidence. Each result identifies the source, when it was checked and whether it came from a live or demonstration service.

Enterprise control architecture

One control layer from intent to settlement.

Cardinal connects the business reason for a payment to available intelligence, transaction effects, policy and protected execution. The decision stays attached to the payment instead of disappearing into a separate risk dashboard.

Open the Trust Centre

Non-custodial product design

Cardinal does not ask customers for seed phrases or private keys. Wallet approval remains with the authorised user.

Evidence provenance

Results identify the available evidence source, observation time and whether the service was live or demonstrative.

Explainable policy

Operational decisions show the matched business rule and reason instead of relying on an unexplained score.

Safe failure behaviour

Where required evidence is unavailable, the controlled workflow is designed to pause for review rather than silently allow.

Current availability: SafeReceive, policy and the customer portal are controlled-pilot capabilities. SafeSend and Escrow use Arbitrum Sepolia test assets. Production scope, evidence providers and limits are agreed during enterprise onboarding.

Status disclosed

SafeReceive + white-labelled customer portal

Control incoming customer payments before acceptance.

Give your property firm, professional practice or payment team a branded workspace for customer requests and transaction records. SafeReceive checks the proposed sending wallet and converts available evidence into an explainable ALLOW, REVIEW or BLOCK decision.

White-labelled customer portal. Give each organisation a separate sign-in, branded payment requests and records linked to its customers, invoices, properties or transactions.

SafeReceive payment controls. Check the source wallet, available evidence and policy result before crediting or settling an incoming payment.

Audit-ready decision records. Retain the source, freshness, matched rule, authorised action and optional comprehensive report against the business file.

Controlled-pilot boundary. SafeReceive and the property portal are available for demonstration and pilot evaluation. Evidence coverage, networks, customer policies and production onboarding are confirmed individually. BLOCK pauses the business acceptance process; it cannot reverse a payment already recorded on a blockchain.
