Stop manipulation in one block
detect deviating price updates and auto-freeze feeds before downstream protocols are affected.
Maintain node uptime
alert operators before balances deplete or clients crash, preventing feed outages.
Protect downstream DeFi
instant risk propagation analysis warns lending pools and DEXs of potential oracle failures.
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?
Oracle's power trillions of dollars in DeFi activity, yet in 2024 and 2025, over $1.2 billion was lost to price feed manipulation and node outages. Attackers exploit thin liquidity, compromise validator keys, or abuse VRF subscriptions to break randomness guarantees.
Price feed manipulation
that triggers wrongful liquidations and collateral drains across lending markets and DEXs.
.avif)
Data delay and staleness
that causes inaccurate TWAPs and depegs during high-volatility periods.
.avif)
Node key compromise
where attackers inject false data across multiple feeds, impacting numerous protocols simultaneously.
.avif)
Gas-spam attacks on oracle nodes
that drain operator balances and halt price feeds during critical gas spikes.

Real-time threat monitoring is now a baseline requirement for oracle networks and data providers

Frequently asked questions
Need more information?
What is real-time monitoring for oracle networks?
It is a continuous validation of oracle feeds, randomness outputs, and node performance to detect manipulation or failures before they affect protocols.
How do price feed attacks harm DeFi users?
They trigger wrongful liquidations, forced depegs, or arbitrage that drains lending pools and destabilizes markets.
Can Guardrail prevent node compromise from spreading across feeds?
Yes. Guardrail validates signature integrity and cross-references multiple sources, isolating compromised nodes before they impact multiple protocols.
What reliability guarantees does Guardrail provide?
Guardrail tracks latency, variance, and correctness, publishing SLA dashboards to prove uptime and accuracy to partners and users.
