Hack prevention.
Question dogma.

Verifiable, embedded hack prevention.

Read the WhitepaperTalk with Us

Phylax enables crypto apps to define and embed verifiable rules into the base layer, preventing hacks so that everyone can deploy capital confidently.

PhEVM: The layer for credible security

30,000

Transactions per second

Write, test and deploy assertions to protect your dapp.

Easy To Use.

dApps define assertions, which describe what state = a hack.

Moreover, they are evaluated off-chain (with a proof posted on-chain if they get violated), enabling dApps to express a wide variety of things.

Powerful.

Assertions are enforced at the sequencer level, meaning they can’t be bypassed.

Write in assertions in Solidity with no code changes, redeployment, or downtime for your protocol when signing up. Also: no false positives as you only prevent states you define.

Verifiable.

Users can verify all aspects of the Credible Layer via the Credible Layer: think DeFi Llama for security.

Enabling everyone to verify the security, vulnerabilities, and exploits of any dApp.

For networks

Fast.

Faster than heuristic analysis.

It can process a block of 1500 transactions in under 50ms. This also means no false positives. Only prevents the behavior the dApps rule out.

For networks

Additive.

No code changes are required at the Sequencer.

The Credible Layer is designed to work on top of the OP-Stack, enabling chains to be Superchain compatible and hack-resistant (even from transactions that are forced included).

Neutral and Opt-in.

The sequencer doesn’t decide which transactions are invalid

It only executes the assertions that have been defined (if they have) by the dApps.
