SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Pact interface design is often inconsistent across modules, leading to brittle integrations and ambiguous contracts. This skill provides a structured approach to define function signatures, interface patterns, and public contracts for Pact-based KDA-CE smart contracts.

Core Features & Use Cases

Interface Design: Document required functions, parameters, and return types for modules to ensure uniform expectations.
Versioning Guidance: Recommend immutable interfaces and safe upgrade paths to preserve data and compatibility.
Use Case: A developer drafts a public API for a treasury module with explicit capability definitions and clear entry points to enforce security.

Quick Start

Define a minimal token interface with balance and transfer functions to begin.

FAQPage Schema

How do I design robust Pact interfaces for smart contracts?▼

Designing robust Pact interfaces involves defining explicit function signatures, typed returns, and clear public contracts to ensure module integrations are secure and unambiguous. This structured approach enforces uniform expectations across KDA-CE contexts.

What is the best way to handle Pact module versioning and upgrades?▼

Pact module versioning requires immutable interfaces and safe upgrade paths to preserve data and compatibility. By maintaining explicit guard conditions and unchanged public function contracts, modules can be upgraded without breaking existing integrations.

How do I add capability patterns to a Pact public function contract?▼

Adding capability patterns to a Pact public function contract requires defining explicit guard conditions and clear entry points within the interface. This enforces security by restricting function access to authorized callers.

Does Pact interface design support typed returns for smart contract modules?▼

Pact interface design explicitly supports typed returns for smart contract modules. Defining clear return types in function signatures ensures uniform expectations and prevents ambiguous contract interactions.

When do I need explicit guard conditions in a Pact module interface?▼

Explicit guard conditions are needed in a Pact module interface whenever defining public function contracts that enforce security. They are essential for restricting access to sensitive operations like treasury module transfers.

Why should Pact interfaces remain immutable during module upgrades?▼

Pact interfaces should remain immutable during module upgrades to preserve data integrity and compatibility. Changing public function contracts breaks existing integrations, so safe upgrade paths must maintain original signatures and typed returns.
