Pre-Signing Simulation, Threat Prevention, & Automated Policy Enforcement

Capabilities
X
Transaction Simulation and Intent Verification

Every transaction is simulated to reveal its true onchain outcome in plain language, surfacing hidden risks, unexpected transfers, and malicious logic before anyone signs.

X
Independent Verification Layer

Transaction Guard validates transactions independently of the wallet UI, detecting discrepancies between what's displayed and what will actually execute as a defense against ByBit-style supply chain attacks.

X
Customizable Policy Engine

Define granular rules to auto-approve, reject, or route transactions for review. Based on security, compliance, financial, organizational, and other parameters.

X
Behavioral Anomaly Detection

Detect unusual timing, amounts, counterparties, and patterns that indicate insider threats or compromised signers, catching what static policies miss.

X
Compliance and Screening Engines

Built-in detection for phishing, sanctioned addresses, pool toxicity, scam tokens, and 20+ additional compliance risk types, evaluated at the point of signing.

Proven in Public. Verified Onchain

Integrates With Your Existing Infrastructure

Transaction Guard operates as an intelligence layer within your signing workflow. No changes to your custody architecture required.

Wallet & Custody Integrations

Whatever your wallet setup, whether multisig, MPC, or programmatic, Transaction Guard integrates natively to protect every transaction before it executes onchain.

How Transaction Guard Works

1
Transaction Initiated

A transaction is proposed through your wallet; multisig, MPC, or API. Transaction Guard intercepts and inspects it before any signatures are collected or execution occurs.

2
Simulate and Analyze

Transaction Guard simulates the full transaction, revealing true on-chain outcomes. AI-powered engines assess security, compliance, financial, behavioral risk and more.

3
 Evaluate Against Policy

The transaction is evaluated against your pre-configured customizable policy for security rules, compliance checks, organizational parameters, or behavioral norms. Result: approve, deny, or route for review.

4
 Enforce Automatically

Approved transactions proceed. Denied transactions are blocked or reverted before reaching the blockchain. Edge cases are routed to your team with full context and recommended action.

Frequently Asked Questions

What is Transaction Guard?

Transaction Guard is a pre-transaction security product that simulates outcomes, prevents threats, and enforces policy on every transaction before it reaches the blockchain preventing blind signing, insider threats, and wallet infrastructure compromise.

How is Transaction Guard different from Onchain Monitoring & Automated Response?

Onchain Monitoring monitors onchain events as they occur and triggers automated responses if certain thresholds or rules are met. Transaction Guard operates before the transaction is executed, simulating the transaction offchain against our detection engines to analyze its true intent and enforcing any policies on transactions before its commitment onchain.

How would Transaction Guard have prevented the ByBit hack?

Transaction Guard independently simulates every transaction to verify its true intent. It would have detected the discrepancy between the displayed transaction and the actual malicious payload, blocking execution before funds were lost. You can learn more about this incident here.

What wallets and custody platforms does it integrate with?

Transaction Guard is natively integrated within Safe and Fordefi, with ready integrations for Fireblocks, Utila, Copper, and other MPC and multisig wallets via API. No changes to your existing custody architecture are required.

What is the Customizable Policy Engine?

A unified engine that lets you define granular rules to auto-approve, reject, or route transactions for review based on security, compliance, financial, and organizational parameters. For example, you could configure a policy that automatically approves any transaction below $10,000 to a whitelisted address, but routes anything above that threshold to a senior signer for manual review.

Does Transaction Guard add latency to the signing flow?

Transaction Guard completes simulation and risk assessment in sub-second response times. For most institutional workflows, analysis is done before the signer finishes reviewing the transaction.

Can Transaction Guard be white-labeled or embedded?

Yes. Transaction Guard is designed for embeddable, white-label integration. Custodians and wallet providers can present it under their own brand as a premium security feature.
