No description provided.

- Introduced the @burnt-labs/abstraxion-backend package, including essential files such as package.json, tsconfig.json, and ESLint configuration. - Set up Jest for testing with a basic configuration. - Updated pnpm-lock.yaml to reflect new dependencies and versions. - Added README and CHANGELOG for documentation and version tracking.

… and encryption - Implemented core functionality for session key management, including storing, retrieving, and revoking session keys. - Added encryption services using AES-256-GCM for secure session key storage. - Created a modular architecture with database adapter interfaces for extensibility. - Introduced comprehensive test coverage for encryption and session key management functionalities. - Updated README and documentation to reflect new features and usage examples.

- Added validation for configuration parameters in the AbstraxionBackend constructor to ensure required fields are provided. - Implemented input validation for userId and other parameters in various methods to improve error handling. - Introduced new error types: UserIdRequiredError and UnknownError for better clarity in error reporting. - Updated error handling to throw specific errors instead of generic ones, enhancing debugging and user feedback.

- Removed the encryptionService property and its instantiation from the AbstraxionBackend class as it is no longer needed. - This change simplifies the class structure and improves maintainability.

- Changed Jest test environment from jsdom to node for better compatibility with backend testing. - Simplified session key generation by directly creating a wallet with a default HD path, removing the previous mnemonic generation method and related code. - Updated the session key object to reference the wallet's mnemonic directly.

- Reformatted code across multiple files for consistent style, including spacing and line breaks. - Updated comments to enhance clarity and maintainability. - Ensured consistent use of double quotes for strings throughout the codebase. - Improved the structure of import statements for better organization. - Enhanced readability of function parameters and object properties by aligning them properly.

You can use the Cosmwasm client here. Hopefully simpler for you.

const client = await abstraxionAuth.getCosmWasmClient() client.sendTokens(....)

Emmm,

ESLint failed, looks like no this method

We should really make the usdc IBC denoms a constant someplace.
