Block seed-drain transactions
risk-score outbound transfers and auto-pause high-risk transactions for human review.
Stop multisig collusion
detect unusual MPC shard activity, geographic mismatches, or coordinated signer anomalies.
Reduce insider risk
surface misconfigurations and suspicious operator activity before they lead to breaches.
Audits Are Just the Beginning
Over 90% of hacks happen in audited protocols after deployment.
Static audits catch code bugs pre-launch, but can't defend against the live threats that emerge in production. Guardrail provides the continuous monitoring that protects your protocol 24/7 where real attacks happen.
Why monitoring?
Wallets and custody providers safeguard trillions in digital assets, but they remain frequent targets of theft and supply-chain compromise. In the first half of 2025 alone, over $1.5 billion was stolen through malware, rogue signers, and phishing drainers.
Seed phrase and private key leaks
that lead to irreversible asset theft across multiple chains.

Rogue firmware and supply chain attacks
where malicious code signs hidden transactions or exfiltrates seeds.

UI manipulation and delegatecall exploits
that trick users into approving malicious contracts or transactions.

Multisig key collusion and insider risks
where MPC shard compromise or misconfigured policies bypass security controls and drain vaults.

Frequently asked questions
Need more information?
What is real-time monitoring for wallets and custody solutions?
Continuous analysis of transactions, firmware integrity, and multisig activity to detect theft or compromise before assets leave custody.
How do firmware attacks compromise wallets?
Malicious or tampered firmware can secretly sign transactions or leak private keys, giving attackers covert access to funds.
Can Guardrail prevent multisig collusion?
Yes. Guardrail monitors MPC and multisig activity for anomalies, such as unusual thresholds, shard misuse, or suspicious geographic/IP patterns.
How does Guardrail stop phishing drainers or UI manipulation?
It tracks transaction approvals against behavioral baselines and flags suspicious contract calls or approval requests.
