Stop cross-chain exploits in one block
detect validator compromises and unauthorized bridge activity before assets are drained.
Prevent MEV and arbitrage abuse
identify sandwich trades and front-running patterns that exploit users mid-transfer.
Ensure oracle feed integrity
cross-reference price data sources to prevent manipulation that triggers incorrect token ratios.
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?
Cross-chain bridges secure billions in locked assets but remain one of the most targeted areas in Web3. Validator compromises, contract flaws, and MEV attacks have led to some of the largest exploits in crypto history.
Validator key compromise and multisig attacks
that authorize fraudulent withdrawals and drain entire bridge reserves.
.avif)
Smart contract exploits and logic flaws
that enable unlimited minting of wrapped tokens and bypass security validations.
.avif)
Cross-chain MEV and oracle manipulation
that exploit price differences and transaction ordering to extract value from user transfers.
.avif)
Liquidity concentration risks
where massive locked asset pools create high-value targets for sophisticated attackers.

Real-time threat monitoring is now a baseline requirement for bridges and cross-chain protocols

Frequently asked questions
Need more information?
What is real-time security monitoring for cross-chain bridges?
Continuous oversight of validators, transactions, and cross-chain messages to detect attacks and exploits before funds are lost.
How do validator key compromises impact bridges?
If validator keys are stolen or abused, attackers can authorize fraudulent withdrawals and drain the entire bridge reserve.
Can Guardrail detect MEV attacks across chains?
Yes. Guardrail analyzes transaction ordering and price flows across chains, flagging sandwich attacks and arbitrage exploitation.
How does Guardrail prevent oracle manipulation?
It cross-references multiple data sources and detects abnormal deviations in price feeds to stop fake ratios or distorted valuations.
