Extra Orchestration Functions & Concepts

When building sophisticated cross-chain applications, you'll work with these powerful orchestration functions:

getChain

• Retrieves chain object for given chainName
• Provides access to chain-specific methods

getBrandInfo

• Gets denom information
• Returns local Brand details
• Provides chain and asset information

asAmount

• Converts denom amount to Amount with brand
• Handles value conversions

What’s ChainHub?

ChainHub acts as a central registry for managing multiple blockchain interactions. Think of it as a control center that keeps track of different chains, their connections, and asset types in one unified interface.

Creation and State

• Creates a new ChainHub in a zone
• Functions as an Exo singleton
• Maintains lightweight state (only caches queries)
• Easily refreshable for updates

Registration Capabilities

Information Access

Key Points:

• Centralized Management: One place to handle all chain interactions
• Dynamic Registration: Add chains and connections as need
• Flexible Updates: Easy to create new versions
• Unified Interface: Consistent way to access cross-chain information
