Defense in Depth

Time-Delayed Execution

Every transaction moving funds enters a mandatory waiting period before execution. This creates a critical window to detect and cancel unauthorized transactions, whether from compromised keys, phishing attacks, or coercion under duress.

On-Chain Policy Engine

Smart contract rules enforce whitelisted addresses and transaction patterns at the protocol level. A transaction signed by a compromised wallet simply won't execute if it violates your policy rules.

Guardian System

Designated guardians can immediately pause pending transactions upon detecting compromise. This human review layer catches threats that automated systems miss, buying time for cancellation of malicious transactions.

Treasury-Scale Threats

Treasuries attract sophisticated threat actors that don't target retail users. Kleidi's defense-in-depth approach combines time-delayed execution, policy enforcement, and guardian oversight to address the threat vectors that compromise standard custody solutions.

Supply chain attacks, clipboard malware, and phishing can compromise signing devices without your knowledge. The on-chain policy engine validates every transaction against your security rules before execution. A compromised hot wallet can only perform pre-approved actions, containing the blast radius.

High-value holders face coercion risks that don't apply to smaller holders. Time-delayed execution creates a mandatory waiting period from 24 hours to 30 days—before funds can move. If you're forced to sign under duress, the transaction can still be canceled during the delay window.
