Notes #

• First 0.1.0 release of this package.

Features #

Implement RPC client package ported from @solana/rpc.

solana_kit_rpc (125 tests):

• createSolanaRpc and createSolanaRpcFromTransport factory functions combining API + transport + transformers
• createDefaultRpcTransport with solana-client: dart/0.0.1 header and request coalescing
• Request coalescing: deduplicates identical JSON-RPC requests within the same microtask
• Deduplication key generation using fastStableStringify for deterministic request hashing
• Integer overflow error creation with human-readable ordinal argument labels
• Default RPC config: confirmed commitment, integer overflow handler

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)
