This guide helps you migrate from the beta versions of the Swig TypeScript SDK to the completely refactored v1.0 release.

Overview of Changes

The v1.0 release represents an overhaul with some breaking changes.

Key Changes

  1. Modular Architecture: Core logic moved to @swig-wallet/lib
  2. Instruction-Based API: Functions return TransactionInstruction[] instead of single instructions
  3. Simplified Package Structure: @swig-wallet/classic now acts as a thin wrapper
  4. Updated Dependencies: Moved from @solana/spl-token to @solana-program/token

Common Migration Issues

Issue: Functions returning arrays instead of single instructions

Solution: Use the spread operator when adding to transactions:

Issue: Authority class methods no longer available

Solution: Use the Swig instance methods instead:

Issue: Import errors for removed classes

Solution: Replace with new function-based API:

Getting Help

If you encounter issues during migration:
  1. Check the API documentation
  2. Review the updated tutorials
  3. Examine the example code
  4. Open an issue on the GitHub repository
The v1.0 release is designed to be more consistent and composable, making it easier to build complex Swig applications once you’ve completed the migration.
