Phylax is security software that stops exploits and tail risk events before settlement, giving your users assurance while you grow capital under management.
“Onchain trading should be fast, verifiable, and secure. We’re excited to bring Phylax’s circuit breakers into production because they share that vision too. As more capital moves onchain, having enforceable safeguards to help protect user balances is critical for reliability and trust.”
“A trader selling options might keep collateral on Derive for months. We’re bringing Phylax’s circuit breakers into production so we can enforce rules on how that capital moves before transactions settle. We expect this kind of protection to become standard for crypto projects, and something traders look for when choosing an exchange.”
“Current monitoring systems detect malicious patterns only after an action has been taken. Catching a malicious transaction before it is mined would be the holy grail of monitoring.”
Dariusz Glowinski — Head of Blockchain Engineering, Euler
“At the end of the day, allocation always follows opportunities. But as onchain markets mature, the infra protecting that capital needs to mature too. Phylax’s approach to security is a major step in ensuring markets stay resilient against threats.”
“Audits are necessary, tests are necessary, but there seems to be something missing. We would prefer something preventive, not something that responds after the problem.”
Guillaume Dupont — Lead Developer, Lagoon

Read about 0xHacks are accelerating and previous approaches to security will not suffice.
Oracles, bridges, wrappers, and admin systems create risk beyond your contracts.
A transaction can follow Ethereum’s rules and still violate your safety intent.
Alerts can speed up response, but they cannot reverse finality.
Building and operating enforcement competes with core product work.
Phylax turns your security and risk policies into circuit breakers the network can enforce before settlement.
We stress-test a replica of your app to find where we can add value.
We test the circuit breakers against numerous adversarial scenarios.
Works with your governance process, no discretionary freezing.
Your circuit breaker policies set the limits, and runtime enforcement stops transactions that break them before settlement.
Whether a transaction arrives through public or private order flow, it must pass the policy check before an integrated builder or sequencer can include it.
Phylax checks what the transaction would do and whether it stays within your rules, then returns a pass or fail.
The network blocks transactions that break your rules before they settle. Transactions that pass can be included as usual.
Protect against abnormal outflows, behavioral anomalies, dependency failures, and compromised keys before they become protocol-wide losses.
Start with an assessmentKeep a compromised path from becoming a protocol-wide loss. Cap abnormal outflows before settlement.
Catch the outlier before it becomes a loss. Drop transactions outside a percentile threshold of normal behavior.
Stop one dependency failure from spreading. Limit new exposure when supported risk signals move out of range.
A stolen key should not become unlimited authority. Constrain high-consequence actions to approved outcomes.
Stop compromised signers from turning privileged access into protocol loss.
Protect lending solvency and keep vault deposits, redemptions, and allocations within mandate.
Reject trades that breach your slippage, price, or settlement limits before they settle.
Block high-risk counterparties and tainted flows before funds enter your protocol.
Keep draft policies staged for weeks, giving your team time to evaluate them before activation.
Backtest policies against a broad span of blockchain history to see how they would have behaved.
Collaborate on policies while controlling exactly who can view, edit, and approve changes.
Fine-tune your protection as conditions change without upgrading your protocol's contracts.
