Migration to v2.0
Telescope v2.0 introduces significant changes that modernize the codebase and improve developer experience. The most notable change is the migration from CosmJS to InterchainJS as the default signing client library.
🚀 Major Changes
InterchainJS as Default
The biggest change in v2.0 is that InterchainJS is now the default instead of CosmJS. This provides:
- Better TypeScript support with improved type safety
- Enhanced multi-chain capabilities for cross-chain applications
- Modern signing patterns with improved developer experience
- Future-proof architecture aligned with the latest Cosmos ecosystem standards
Environment Preset Changes
The default environment preset has changed from "default" to "v-next", enabling more modern code generation patterns.
