Verify Transaction Intent. Enforce Policy Automatically.
Pre-signing simulation, threat prevention, and customizable policy enforcement that secures every transaction before it reaches the blockchain.
Pre-Signing Simulation, Threat Prevention, and Automated Policy Enforcement
Every transaction is simulated to reveal its true onchain outcome in plain language, surfacing hidden risks, unexpected transfers, and malicious logic before anyone signs.
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.
Define granular rules to auto-approve, reject, or route transactions for review. Based on security, compliance, financial, organizational, and other parameters.
Detect unusual timing, amounts, counterparties, and patterns that indicate insider threats or compromised signers, catching what static policies miss.
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
<90% Reduction in Manual Reviews
Edge Capital scaled transaction security and expanded its DeFi reach with Hypernative Transaction Guard, deploying dozens of custom transaction-level checks and cutting manual reviews by up to 90%.
We needed real-time interpretation and enforcement across all our vaults to protect against both external and internal threats.
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
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.
Transaction Guard simulates the full transaction, revealing true on-chain outcomes. AI-powered engines assess security, compliance, financial, behavioral risk and more.
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.
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
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.
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.
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.
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.
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.
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.
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.
