💥 Breaking Change

@solana/kit v7.0.0 upstream sync (foundational breaking changes)

Ports the foundational breaking changes from @solana/kit v7.0.0:

• solana_kit_errors: new transactionIntrospection error domain + codes (transactionFailedToDecompileInstructionAccountIndexOutOfRange, transactionIntrospectionCannotDecodeJsonParsedTransaction, transactionIntrospectionUnrecognizedGetTransactionResponse) and instruction-plans max-instructions codes (instructionPlansInvalidMaxInstructionsPerTransaction, instructionPlansMaxInstructionsPerTransactionExceeded).
• solana_kit_codecs_data_structures: createDependentStructDecoder fluent builder for structs whose later fields depend on earlier decoded values.
• solana_kit_instruction_plans: configurable maxInstructionsPerTransaction (default 16, limit 64) on TransactionPlannerConfig, individual TransactionPlanner invocations, and MessagePacker; invocation-specific planner values take precedence without leaking to later calls.
• solana_kit_rpc_types: isSolanaRpcResponse runtime guard.
• solana_kit: removed the local getMinimumBalanceForRentExemption helper (rent exemption is becoming dynamic; use the RPC method instead).
• solana_kit_subscribable: ReactiveStreamStore v7 rewrite — caller-driven connect()/reset()/withSignal(), starts idle, collapses retrying into loading (stale-while-revalidate), renames getUnifiedState() → getState(); removed retry(), value-only getState(), getError(). ReactiveActionStore now passes a fresh CancellationToken to every action, cancels superseded/reset/disposed dispatches, suppresses late outcomes, exposes caller cancellation through withSignal(), and preserves stale results and errors while running.
• solana_kit_transaction_introspection: new first-class package porting @solana/transaction-introspection — RPC transaction decoding, instruction and inner-instruction extraction, loaded-address resolution, and instruction walking helpers; re-exported from the solana_kit umbrella.
• solana_kit_rpc_parsed_types / solana_kit_rpc_transformers / solana_kit_rpc_api: Agave 4.1.0 parsed-account types — vote commissions/latency as int (not BigInt); rent sysvar union (lamportsPerByte vs deprecated burnPercent/exemptionThreshold/ lamportsPerByteYear); stake warmupCooldownRate optional; config slashPenalty/warmupCooldownRate deprecated; keep vote commissions and latency as int in the numeric-keypath allow-lists.

Migration: getMinimumBalanceForRentExemption(space) → rpc.getMinimumBalanceForRentExemption(space).send(); store.retry() → store.connect(); store.getUnifiedState() → store.getState(); the deprecated ReactiveStore/createReactiveStoreFromStreams → createReactiveStreamStore; reactive actions must migrate from (args) async => result to (signal, args) async => result.

// Before
final lamports = getMinimumBalanceForRentExemption(space);
store.retry();
final state = store.getUnifiedState();

// After
final lamports = await rpc.getMinimumBalanceForRentExemption(space).send();
store.connect();
final state = store.getState();

🚀 Feature

@solana/kit v7.1.0 upstream sync

Ports the @solana/kit v7.1.0 changes into the Dart SDK.

solana_kit_errors

Adds the three new error codes introduced in @solana/kit v7.1.0:

• offchainMessageContentDoesNotMatchExpected (5607018) — from @solana/offchain-messages's new assertOffchainMessageV1Equal helper.
• offchainMessageRequiredSignatoriesDoNotMatchExpected (5607019) — same.
• subscribableStreamClosedWithoutError (8195001) — from @solana/subscribable's new bridgeStoreToAsyncIterable helper.

solana_kit_subscribable

Adds bridgeStoreToAsyncIterable, which adapts a ReactiveStreamStore into a pull-based Stream (the Dart equivalent of the upstream AsyncIterable). It seeds from the store's current snapshot, yields loaded values (latest-wins), throws on error (substituting subscribableStreamClosedWithoutError when the error payload is nullish), and ends cleanly when the CancellationToken fires. The caller owns the store's lifecycle (connect()/reset()).

solana_kit_offchain_messages

Adds assertOffchainMessageV1Equal, which asserts that a version 1 offchain message received from an untrusted signer is the message you expected it to sign. Compares content (reporting UTF-8 byte lengths) and required signatories (order-insensitive, sorted for comparison), throwing offchainMessageContentDoesNotMatchExpected / offchainMessageRequiredSignatoriesDoNotMatchExpected on mismatch.

solana_kit_instruction_plans

createTransactionPlanExecutor's executeTransactionMessage callback may now return the context of a successful result (a map that must include a signature) instead of a Signature or Transaction. The returned context is merged with the mutable context, taking precedence. Returning a Signature or Transaction still behaves as before (stored as context['signature'] / context['transaction'] with the signature derived).

solana_kit_rpc_transformers / solana_kit_rpc_api

• New tokenBalancesConfigs export (accountIndex, uiTokenAmount.decimals, uiTokenAmount.uiAmount).
• getTransaction, getBlock, and simulateTransaction now allow-list uiTokenAmount.uiAmount (previously upcast to BigInt when whole).
• simulateTransaction now allow-lists token-balance accountIndex and uiTokenAmount.decimals.
• getTransaction and getBlock now allow-list the transaction version (previously arrived as 0n while typechecking as 0).
• getTransactionsForAddress allowed-numeric keypaths.

solana_kit

Adds the v7.1.0 client-interface helpers:

• ClientWithGetMinimumBalance and ClientWithFetchAccounts interfaces.
• createClientWithGetMinimumBalanceFromRpc — computes the rent-exempt minimum balance via getMinimumBalanceForRentExemption (with the withoutHeader rate-recovery trick).
• createClientWithFetchAccountsFromRpc — dispatches on address count (getAccountInfo / getMultipleAccounts / empty short-circuit).
• createClientWithInterfacesFromRpc — returns both interfaces.

Also re-exports the @solana/promises helpers as Dart counterparts: isAbortError, getAbortablePromise, and safeRace (adapted to Dart's cancellation model via CancellationToken; AbortError lives in solana_kit_subscribable).

solana_kit_rpc_api

Adds the getTransactionsForAddress RPC method request side: config (commitment, filters, limit, minContextSlot, paginationToken, sortOrder, encoding, maxSupportedTransactionVersion, transactionDetails), filters (blockTime/signature/slot comparisons, status, tokenAccounts), and the params builder.

solana_kit_rpc_types

• Adds the getTransactionsForAddress response types: signatures and full modes (with per-entry base fields, transaction/status variants, and the TransactionDetails enum).
• Adds the shared meta.costUnits field to the transaction meta types.

Already present in the Dart port (no change needed):

• @solana/codecs-data-structures getBitArrayEncoder next-offset fix (offset + size) — the Dart encoder already returns offset + size.
• @solana/transaction-messages compressTransactionMessageUsingAddressLookupTables rejecting v1 transactions — a compile-time-only type narrowing upstream; not expressible in Dart's single-class TransactionMessage model, so no runtime change.

@solana/react changes are not ported (React-only).

🐛 Fixed

Kit-plugin style Surfpool client + SDK-based integration tests

solana_kit_surfpool (minor)

Add createSurfpoolClient() / connectSurfpoolClient() returning a SurfpoolClient wired up like the @solana/surfpool/kit plugin for TypeScript:

• rpc / rpcSubscriptions — Solana Kit RPC and subscriptions clients pointed at the Surfnet.
• payer — the Surfnet's pre-funded KeyPairSigner (embedded mode) or a caller-provided funded signer (attach mode).
• cheatcodes — a typed SurfnetCheatcodes RPC covering every surfnet_* cheatcode with the prefix stripped (timeTravel, pauseClock, setAccount, writeProgram, …).
• rpcUrl / wsUrl — the Surfnet's HTTP and WebSocket URLs.
• airdrop / getMinimumBalance — funding and rent-exemption helpers.
• stop() — idempotent teardown that stops the Surfnet when this client started it.

createSurfpoolClient stops the Surfnet if wiring fails, so no orphaned process or ports are left behind. The new API is fully unit-tested with 100% patch coverage.

codama-renderers-dart (patch)

Fix visitSizePrefixType so BigInt-width size prefixes (u64/u128/i64/i128) generate transformEncoder/transformDecoder wrappers instead of substituting u32. The system program's bincode String length is u64, so the u32 substitution broke on-chain encoding of seed fields.

solana_kit_system (patch)

Regenerate the system program client with the size-prefix renderer fix; createAccountWithSeed, allocateWithSeed, assignWithSeed, and transferSolWithSeed now encode their u64 String-length prefixes correctly.

solana_kit_errors (patch)

Fix getSolanaErrorFromTransactionError to handle account_index values returned as BigInt by some RPC nodes (e.g. SurfPool), matching the earlier instruction-error-index fix.

solana_kit (patch)

Convert test/integration/rpc_basic_test.dart to start its own Surfpool via the SDK instead of requiring an externally launched validator.

solana_kit_mpl_bubblegum (patch)

Convert the compressed-NFT integration test to start its own Surfpool via the SDK; add solana_kit_surfpool as a dev dependency.

solana_kit_integration_tests (minor)

Integration tests now start their own Surfpool per test file via the SDK (auto-allocated ports, parallel-safe) instead of requiring an externally launched instance. Adds the gap-coverage tests: loader full deploy, system seed-based instructions, config store (committed config-v3.0.0.so artifact), subscriptions on-chain lifecycle, ALT extend/deactivate/close, error paths, token/2022 transfer+burn+setAuthority+closeAccount, stake authorize, and ATA idempotency.

// Before: manual Surfnet wiring
final surfnet = await Surfnet.start();
final rpc = createSolanaRpc(surfnet.rpcUrl);

// After: kit-plugin style client
final client = await createSurfpoolClient();
final rpc = client.rpc;
final payer = client.payer;
await client.cheatcodes.timeTravel(...);
await client.stop();

0.6.0 - 2026-08-12

💥 Breaking Change

Remove deprecated APIs across the SDK

Breaking change. Clears every remove_deprecations_in_breaking_versions lint warning by deleting deprecated members and migrating call sites to their documented replacements. No deprecations are suppressed; each deprecated declaration is removed.

createEmptyClient (solana_kit)

Removed the deprecated createEmptyClient alias. Use createClient instead.

// Before
final client = createEmptyClient({'ready': true});
// After
final client = createClient({'ready': true});

Deprecated fixed-point rounding modes (solana_kit_fixed_points)

Removed the deprecated FixedPointRoundingMode values down, up, and halfUp. The surviving modes are strict, floor, ceil, trunc, round.

• down was a duplicate of trunc — use FixedPointRoundingMode.trunc.
• halfUp was a duplicate of round — use FixedPointRoundingMode.round.
• up ("round away from zero") has no single replacement. Use floor or ceil depending on the sign of the value, or round for nearest.

Deprecated Pipe extension (solana_kit_functional)

Removed the deprecated Pipe extension from solana_kit_functional. Pipe is re-exported from solana_kit_transaction_messages and the solana_kit umbrella. Switch imports accordingly:

// Before
import 'package:solana_kit_functional/solana_kit_functional.dart';
// After
import 'package:solana_kit_transaction_messages/solana_kit_transaction_messages.dart';

solana_kit no longer depends on solana_kit_functional. The solana_kit_functional package is now an empty placeholder pending full retirement.

Deprecated subscriptions compatibility APIs

The deprecated AbortSignal/AbortController and DataPublisher/WritableDataPublisher/createDataPublisher compatibility APIs were the core transport substrate of the subscriptions stack, not a thin compatibility layer. They are replaced by stream-native and cancellation-token equivalents.

Cancellation

• AbortSignal → CancellationToken (from solana_kit_subscribable)
• AbortController → CancellationTokenSource (from solana_kit_subscribable)
• controller.signal → source.token
• controller.abort([reason]) → source.cancel([reason])
• signal.isAborted → token.isCancelled
• signal.reason → token.reason
• signal.future → token.future

Public field/parameter names that held an AbortSignal (e.g. abortSignal, signal) are kept; only their type changed to CancellationToken. CancellationToken and CancellationTokenSource are re-exported from solana_kit_rpc_subscriptions and solana_kit_rpc_subscriptions_channel_websocket so consumers do not need a direct solana_kit_subscribable dependency.

AbortError, isAbortError, getAbortableFuture, and normalClosureCode remain in solana_kit_rpc_subscriptions_channel_websocket (behavior unchanged; their AbortSignal? params are now CancellationToken?).

DataPublisher → NotificationStreams

• The transport contract changed from Future<DataPublisher> to Future<NotificationStreams>.
• RpcSubscriptionsChannel now exposes NotificationStreams get streams instead of the on(channelName, subscriber) method.
• createDataPublisher(), WritableDataPublisher, DataPublisher, and the DataPublisherStreams extension are removed.
• The *FromDataPublisher helpers are removed: createStreamFromDataPublisher, StreamFromDataPublisherConfig, createAsyncIterableFromDataPublisher, demultiplexDataPublisher, createReactiveStoreFromDataPublisher, createReactiveStreamStoreFromDataPublisher.
• The stream-native helpers are kept: ChannelStreamController, createStreamFromDataAndErrorStreams, demultiplexStream, createReactiveStoreFromStreams, ReactiveStore, ReactiveStreamStore, createReactiveStreamStore.

Public subscription APIs

PendingRpcSubscriptionsRequest.subscribe() and .reactive() still return Future<Stream<T>> and Future<ReactiveStore<T>> respectively. Internally they now consume NotificationStreams.notifications / .errors instead of DataPublisher channels.

Migration

// Before
final controller = AbortController();
final stream = await pending.subscribe(
  RpcSubscribeOptions(abortSignal: controller.signal),
);
controller.abort();

// After
final source = CancellationTokenSource();
final stream = await pending.subscribe(
  RpcSubscribeOptions(abortSignal: source.token),
);
source.cancel();

Upstream @solana/kit 6.10.0 parity

Updates core packages to match upstream @solana/kit 6.10.0:

• solana_kit_errors: Adds 6 new error codes from @solana/errors 6.10: JSON_RPC__SERVER_ERROR_NO_SLOT_HISTORY (-32021), JSON_RPC__SERVER_ERROR_FILTER_TRANSACTION_NOT_FOUND (-32020), TRANSACTION__FAILED_TO_ESTIMATE_LOADED_ACCOUNTS_DATA_SIZE_LIMIT (5663036), TRANSACTION__FAILED_WHEN_SIMULATING_TO_ESTIMATE_RESOURCE_LIMITS (5663037), SUBSCRIBABLE__RETRY_NOT_SUPPORTED (8195000), WALLET__ACCOUNT_NOT_AVAILABLE (8900003). Adds subscribable and wallet error domains. Updates unwrapSimulationError to treat resource-limit simulation failures as simulation errors.

• solana_kit_subscribable: Adds ReactiveActionStore<TArgs, TResult> with idle/running/success/error states, dispatch/dispatchAsync/reset. Adds ReactiveStreamStore<T> with loading/loaded/error/retrying states, getUnifiedState and retry. Mirrors upstream @solana/subscribable 6.10.

• solana_kit_rpc_spec: Adds PendingRpcRequest.reactiveStore() returning a ReactiveActionStore for reactive request dispatch.

• solana_kit_rpc_api: Adds clientId to ClusterNode. Documents tpu and tpuForwards as deprecated in favor of QUIC fields.

• solana_kit_transaction_messages: Adds resource-limit estimation helpers: ResourceLimitsEstimate, estimateResourceLimitsFactory, estimateAndSetResourceLimitsFactory, fillTransactionMessageProvisoryResourceLimits, getTransactionMessageLoadedAccountsDataSizeLimit, setTransactionMessageLoadedAccountsDataSizeLimit.

0.5.0 - 2026-06-01

💥 Breaking Change

Raise minimum Dart SDK to 3.12

Raise the minimum supported Dart SDK constraint to ^3.12.0 across public Dart packages.

This is a breaking change because consumers must use Dart 3.12 or newer. Flutter consumers must use a Flutter SDK that bundles Dart 3.12 or newer.

environment:
  sdk: ^3.12.0

🐛 Fixed

Add well-known program, sysvar, SPL, Metaplex, and token mint address constants

Add centralized address constants to solana_kit_addresses so that any package can reference well-known on-chain addresses without importing the full domain package or hardcoding strings.

New exports:

• program_addresses.dart — All Agave/Solana native program addresses (system, ALT, BPF loaders, compute budget, config, stake, vote, etc.)
• sysvar_addresses.dart — All sysvar addresses (clock, rent, recentBlockhashes, fees, rewards, etc.) plus the sysvar owner address
• spl_addresses.dart — SPL program addresses (Token, Token-2022, ATA, Memo, Memo Legacy)
• metaplex_addresses.dart — Metaplex program addresses (Token Metadata, Bubblegum, Auth Rules, Core, SPL Account Compression, Noop)
• well_known_addresses.dart — Well-known token mint addresses (Wrapped SOL, USDC, USDT)

Also re-exports from solana_kit_address (Address type, codecs, comparator, PublicKey) and solana_kit_address_constants (well-known address constants).
