@le-space/ucanto-core

@le-space/ucanto-core provides the foundational components for defining, validating, and executing UCAN-based Remote Procedure Calls (RPC). It serves as the core module for the ucanto ecosystem, enabling capability-based access control and secure interactions between clients and services.

What It Provides

• Capability Definition & Validation: Enables the creation of structured capabilities with clear semantics.
• UCAN Invocation Execution: Supports processing and verifying UCAN-based RPC calls.
• Extensibility: Designed to integrate seamlessly with other ucanto modules.

How It Fits with Other Modules

• @le-space/ucanto-server: Builds on ucanto/core to provide a complete UCAN-based RPC server.
• @le-space/ucanto-interface: Provides shared type definitions and contracts.
• @le-space/ucanto-transport: Implements encoding and transport mechanisms.
• @le-space/ucanto-principal: Handles identity management and cryptographic operations.
