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 spec package ported from @solana/rpc-spec.

solana_kit_rpc_spec (23 tests):

• JsonRpcApi with configurable request/response transformers creating RpcPlan objects
• RpcPlan<T> describing how to execute an RPC request with lazy execution
• RpcTransport typedef for pluggable transport layer
• Rpc client that wraps API + transport, returning PendingRpcRequest objects
• PendingRpcRequest<T> with send() method for deferred execution
• isJsonRpcPayload type guard for JSON-RPC 2.0 payload validation
• RpcApi abstract class with JsonRpcApiAdapter and MapRpcApi implementations
