Phylax

Building verifiable, embedded hack prevention.

Phylax Logo

Phylax was founded in the aftermath of the $200mm Nomad hack and is backed by $4.5mm from Nascent, Figment Capital, Robot Ventures, and other leading investors and angels.

Adoption requires trust, and trust requires security.

The Credible Layer is a network extension that enables apps to define security rules and prevents transactions from violating them. These rules are defined in Solidity, executed off-chain, and enforced on-chain.

Since these rules are verifiable, apps can turn implicit security assumptions into an explicit security posture so that users can trust the apps they use.

Key Repositories

This organization hosts Phylax Systems' open-source components. Key repositories include:

  • assertion-da: Assertion DA functions as a temporary data availability layer for the Phylax Credible layer. It stores and makes assertions publicly available via a JSON-RPC interface.
  • assertion-examples: Contains an extensive collection of assertion examples for different use cases as well as concrete examples of previous hacks that could have been prevented with the Credible Layer.
  • assertion-executor: The executor for the Phylax Credible Layer, responsible for validating assertions against transactions.
  • credible-layer-contracts: The on-chain contracts for the Credible Layer
  • credible-layer-starter: A repository that contains a couple of starter projects that work out of the box.
  • credible-std: The standard library for the Phylax Credible Layer, providing utilities and "cheatcodes" for writing assertions.
  • pcl: A command line tool used for testing, authenticating, storing and submitting assertions.
  • phoundry: A modified version of Foundry that supports the Credible Layer.

For a comprehensive overview of the Credible Layer, please refer to the Credible Layer documentation.
