💥 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 ReactiveActionStore now passes a fresh CancellationToken to every action, cancels superseded/reset/disposed dispatches, suppresses late outcomes, exposes caller cancellation through withSignal(), and preserves stale results and errors while running.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).

Owner: @ifiokjr · Review: PR #206

🐛 Fixed

On-chain integration tests for program clients + sendTransaction encoding fix

solana_kit_transaction_confirmation (patch)

Fix sendAndConfirmTransaction so the sendTransaction RPC call declares encoding: base64. The helper encodes the transaction as base64 via getBase64EncodedWireTransaction but previously left the encoding field unset, so real RPC nodes (including SurfPool) defaulted to base58 and rejected the payload with invalid base58 encoding. This path had only been exercised against a mocked transport, so the bug was latent.

solana_kit_errors (patch)

Fix getSolanaErrorFromTransactionError to handle instruction-error indices returned as BigInt (as SurfPool does). The instruction index was cast as num, which threw _BigIntImpl is not a subtype of num and masked the real on-chain instruction error. It now converts BigInt indices to int.

solana_kit_address_constants / solana_kit_spl_account_compression (patch)

Fix the SPL Account Compression, Noop, and MPL Bubblegum program addresses to the live mainnet IDs:

• splAccountCompressionProgramAddress: cmtDvXzGgh4bcrDY2gZqFaGQqat4RNQPhKJ4jAc7uLi -> cmtDvXumGCrqC1Age74AVPhSRVXJMd8PJS91L8KbNCK
• noopProgramAddress: noopb9bkMVz3tFhZ5L7bJGby9DreGG5J2P4V4Wxe8tK -> noopb9bkMVfRPU8AsbpTUg8AQkHtKwMYZiFUjNRtMmV
• mplBubblegumProgramAddress: BGUMAp9Gph7G9Jn2tU58R5L2qPG1Mj9HP7G3G7VYV2Ma -> BGUMAp9Gq7iTEuizy4pqaxsTyUCBK68MDfK752saRPUY
• stakeConfigAddress: StakeConfig1111111111111111111111111111 (truncated, invalid length) -> StakeConfig11111111111111111111111111111111

The previous values point to accounts that do not exist on mainnet. An audit of every constant in the package against mainnet confirmed all other addresses are correct (native/runtime programs and sysvars are canonical per solana-sdk-ids; some native programs and lazily-created sysvars legitimately have no materialized account). SurfPool integration tests for MPL Bubblegum confirmed the corrected IDs resolve to deployed programs.

solana_kit_integration_tests (new, internal)

A non-published workspace package that runs every generated program client end-to-end against a local SurfPool Surfnet. It ships a shared IntegrationTestEnv harness (connects-or-starts SurfPool, funds a payer, builds/signs/sends/confirms transactions, deploys programs) and on-chain suites that assert the real on-chain outcome of each instruction:

• Builtin programs: Memo, System (transfer), Compute Budget, Token (createMint -> mintTo), Token-2022, Associated Token Account, Address Lookup Table, Stake (initialize), and BPF Loader (initializeBuffer).
• Subscriptions: the compiled program (.so) is committed under config/programs/ and deployed on-chain; initSubscriptionAuthority runs and its PDA is verified on-chain.
• MPL Bubblegum: Bubblegum + SPL Account Compression + Noop are deployed on-chain (verified executable + owned by the BPF loader) and the full compressed-NFT lifecycle runs end-to-end: createTree (with the merkle-tree account sized per the account-compression layout formulas, 31800 bytes for (maxDepth=14, maxBufferSize=64, canopyDepth=0)) -> mintV1 -> transfer (leaf owner signs) -> burn (new owner signs). The tree state (root, proof, index) is parsed from the on-chain ConcurrentMerkleTree account and the data/creator hashes are recomputed client-side to drive transfer and burn.

The compiled .so artifacts are committed (not rebuilt per run) and pinned to config/reference-repos.json; see config/programs/README.md for how they are built and when they must be regenerated. Artifact names follow <package-name-minus-solana_kit>-<program-version>.so (e.g. subscriptions-v0.5.0.so, mpl_bubblegum-v0.12.0.so, spl_account_compression-v0.3.3.so, noop-v0.2.0.so). All four are compiled from the pinned source with cargo build-sbf (agave 4.2.0 / platform-tools v1.54) via scripts/build_program_artifacts.mjs (devenv task build:program-artifacts), which also applies the ahash 0.7.6 stdsimd patch needed by the solana-program 1.18.x programs and verifies the baked-in program IDs.

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();
