});The Balmy SDK is a comprehensive TypeScript library that provides a unified interface for interacting with the Balmy protocol and various blockchain networks. The Balmy SDK allows you to interact with the Balmy protocol, providing efficient tools to manage token balances, retrieve trade quotes from DEX aggregators, and check token holdings across multiple chains. It's designed to be modular, with each functionality organized into specialized services that handle specific aspects of blockchain interaction.
The SDK is divided into the following services:
- Allowances Service: Manage token approvals and permissions across different chains
- Balances Service: Query token balances across multiple chains and tokens
- Quotes Service: Get optimized swap quotes from various DEX aggregators
- Gas Service: Optimize transaction costs and estimate gas prices
- Prices Service: Retrieve token price information across multiple chains
- Metadata Service: Access token metadata and information
- Permit2 Service: Manage token approvals using the Permit2 protocol
- DCA Service: Set up and manage Dollar Cost Averaging positions
- Earn Service: Handle yield farming operations
Each service provides a focused set of functionality while maintaining a consistent interface and error handling approach. This modular design allows developers to use only the services they need while ensuring a cohesive experience across the entire SDK.
The Allowances Service provides functionality to check and manage token allowances across different chains.
