Introducing Phage
Programmable Transaction Middleware for Ethereum Nodes
Phage is a rust based library that provides programmable transaction middleware for Ethereum nodes
Current transaction broadcasting infrastructure is passive
Existing protection tools are concentrated on the wallet layer
Phage modules enable nodes to make automated decisions
With Phage you can build…
✅ Custom RPC methods
✅ Intelligent transaction routing
✅ Real time threat interception
✅ Invisible policy enforcement & alerting
Build modules in 3 steps
Define the services
Define the rules
Install on your node
Modules contain hooks for external services
Rules are defined using Banyan
The declarative policy language for modules based on Cedar by AWS
Define transaction rules based on decoded & enriched transaction data
@name("WARN-NATIVE-ASSET-THRESHOLD") @advice("Warn when sending funds over X threshold") @notification("WEBHOOK-e03a0aa1") forbid ( principal, action == Action::"EOATransaction", resource ) when { context.value.u256GreaterThan(principal.valueLimit) };

Use modules to dynamically route & bundle transactions
Enrich MPC transaction services with policies & detailed context
Intercept threats with external datasets & AI models
