Key Benefits of the Credible Layer

​
For dApps

  • Network-Native, Rule-Based Security: Every transaction that violates your rules is dropped by the network at the sequencer level
  • Easy to Use: Written in Solidity with foundry-like syntax, assertions require no contract modifications or downtime during implementation
  • Transparent Security: All active assertions are public and verifiable by users and auditors

​
For Networks

  • No Lock-In: Runs natively as part of your network infrastructure with no external dependencies
  • No Throughput Degradation: Assertions execute in parallel during sequencing without impacting block times
  • Attract Institutional Capital: Reduce hack probability and provide auditable security rules for risk-averse institutions

​
For Users

  • Visible Protection: See exactly which protocols are protected and by what rules through the Transparency Dashboard
  • Provable Security: Verify the specific security guarantees protecting your funds
  • Confidence: Deploy capital knowing malicious transactions are prevented before they can execute

Installation

Set up your development environment and install pcl.
