TypeScript Packages

The TypeScript protocol SDK surface is split by runtime and abstraction level.

Choose a package

Package	Use it when
@swig-wallet/classic	you are on Web3.js 1.x
@swig-wallet/kit	you are on Solana Kit / Web3.js 2.0
@swig-wallet/lib	you need shared protocol logic and lower-level helpers
@swig-wallet/coder	you need account or instruction encoding and decoding

What these packages cover

• instruction building
• wallet account fetching
• PDA derivation
• authority and action helpers
• version-aware handling for v1 and v2 Swig accounts

Classic vs Kit

@swig-wallet/classic and @swig-wallet/kit cover the same product area, but they target different Solana client stacks.

• classic returns TransactionInstruction[] and works with Connection
• kit returns Kit instructions and works with Rpc<GetAccountInfoApi>
