ptb-composability

What problem does it solve?

PTB composability in Sui enables atomic multi-command sequences but can introduce security risks if public functions are too broadly exposed or misused across commands, potentially enabling attackers to manipulate state or route assets within a single transaction.

Core Features & Use Cases

• Identify which protocol functions are public and usable within PTB workflows to surface exposure points.
• Model single-call assumptions, value routing, and multi-step sequencing to reveal ordering and routing vulnerabilities.
• Provide mitigations and best practices for safe PTB design in Sui modules, including access control and explicit transfer guarantees.

Quick Start

Run a PTB composability audit on your Sui module to identify public functions, potential single-call and value-routing vulnerabilities, and suggested mitigations.
