This new version of the Forte Rules Engine is under active development and not yet audited.

The Forte Rules Engine lets you define powerful, composable on-chain policies without hardcoding every rule into your smart contracts.

Whether you’re aiming for compliance, risk management, economic safeguards, or app-specific logic, the Forte Rules Engine lets you define what should happen and enforces that logic at runtime.

​
Why Use the Forte Rules Engine?

  • 🚀 Modular enforcement: Define and evolve logic outside your core contracts and without the need for Solidity and audits
  • 🔄 Reusable and transparent: Keep logic clean, visible, and upgrade-friendly
  • 🔐 Immutable when needed: Cement policies when you’re ready to lock behavior
  • 🔌 Composable: Use external data or trigger external logic via foreign contract calls

​
Key Capabilities

  • Define and deploy policies that are each composed of a set of rules
  • Rules trigger effects based on conditional logic that you define
  • Subscribe your application contract(s) to one or more policies

​
Components

  • On-chain enforcement engine – Stores policy configurations and executes policy logic
  • SDK – Programmatic access and integration
  • User-friendly UI – Visual editor for building policies (coming soon)
  • Docs & Guides – You’re here!

​
Core Concepts

Policies

Top-level containers that define which rules to run and when. All configuration logic lives inside a policy.

Rules

Conditional statements that evaluate expressions and trigger effects based on the outcome.

Trackers

Persistent, on-chain values that store historical or computed data to be used by rules.

Effects

The actions triggered by rules—like reverting, emitting events, updating trackers, or calling foreign contracts.
