The problem

One signature is the difference
between settlement and total loss.

Wallets are the last line of defense — and they were never designed for it. Cardinal sits between intent and execution, protecting every transaction before value moves.

$0.0B+ lost to preventable transaction errors and contract approvals in the last 24 months.

Most users find out only after the block is final. There is no undo on-chain, no fraud reversal, no merchant chargeback.

Cardinal moves the decision earlier — to the moment intent forms, before value moves on-chain.

How Cardinal works

Cardinal checks before
the wallet asks you to sign.

Cardinal scans risk before signature and routes users into safer settlement flows like SafeSend and escrow.

01
Detect intent
Cardinal reads the transaction your wallet is about to ask you to sign.
02
Analyze risk
Wallet intelligence, contract checks, and simulation run in parallel.
03
Give verdict
Low Risk · Proceed, Review Required, or Critical Risk — in plain English.
04
Route to safe settlement
High-risk moves can route into SafeSend or escrow instead of a blind signature.
Cardinal Protection Engine

No. Cardinal is the trust layer between wallets, exchanges, and chains. We scan risk before signature, explain findings in plain English, and route users into safer settlement flows — we never hold custody.
