Notes #

• First 0.1.0 release of this package.

Features #

Initial scaffold for 17 higher-level packages including the full RPC stack,

program interaction layers, and the umbrella package. Each package has its pubspec.yaml with correct workspace dependencies, shared analysis_options.yaml, and an empty barrel export file ready for implementation.

Package groups scaffolded:

• RPC Stack: rpc_types (base types), rpc_spec_types, rpc_spec (specification), rpc_api (method definitions), rpc_parsed_types, rpc_transformers (response processing), rpc_transport_http (HTTP transport), rpc (primary client)
• RPC Subscriptions: rpc_subscriptions_api, rpc_subscriptions_channel_websocket, rpc_subscriptions (WebSocket subscription client)
• Programs & Accounts: accounts (fetching/decoding), programs (utilities), program_client_core (base client), sysvars (system variables)
• Transaction Lifecycle: transaction_confirmation (polling/confirmation)
• Umbrella: solana_kit (re-exports all packages for convenience)

Implement RPC transformers package ported from @solana/rpc-transformers.

solana_kit_rpc_transformers (524 tests):

• Request transformers: BigInt downcast, integer overflow detection, default commitment injection
• Response transformers: BigInt upcast, JSON-RPC error throwing with Solana error unwrapping, result extraction
• Tree traversal utilities with key path wildcards for deep object walking
• Default commitment handling for 39 RPC methods with per-method config position mapping
• Preflight error unwrapping from -32002 JSON-RPC errors
• Composable transformer pipelines via getDefaultRequestTransformerForSolanaRpc and getDefaultResponseTransformerForSolanaRpc
