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 types package ported from @solana/rpc-types.

solana_kit_rpc_types (85 tests):

• Blockhash extension type with validation, codec (32-byte base58), and comparator
• Lamports extension type (0 to 2^64-1) with generic encoder/decoder/codec wrappers
• UnixTimestamp extension type (i64 range) with validation
• StringifiedBigInt and StringifiedNumber extension types with validation
• Commitment enum (processed, confirmed, finalized) with comparator
• MicroLamports, SignedLamports, Slot, Epoch type aliases
• Encoded data types: Base58EncodedBytes, Base64EncodedBytes, data response records
• Account info types: AccountInfoBase and encoding-specific variants
• TokenAmount, TokenBalance for SPL token data
• TransactionError and InstructionError sealed class hierarchies
• TransactionVersion, Reward, TransactionStatus types
• Cluster URL types: MainnetUrl, DevnetUrl, TestnetUrl
• SolanaRpcResponse<T> wrapper with slot context
• Account filter types: DataSlice, memcmp and datasize filters
