Replaces derived types (Parameters<typeof ...>, ReturnType<typeof ...>, inline literal unions) with the named types the granular @solana/* packages and our own packages already export.

Changed

• solana-batch-accounts-loader RpcWithGetMultipleAccounts: Parameters<typeof import("@solana/accounts").fetchEncodedAccounts>[0] → Rpc<GetMultipleAccountsApi>. The shape is the same; @solana/accounts just doesn't export its GetMultipleAccountsApi. Adds @solana/rpc-api and @solana/rpc-spec as peer and dev deps, which is why this is a minor bump. Type-checked against a full kit rpc (grill-headless-provider) and against fetchEncodedAccounts (gill-extra/fetch-token-info-for-mint).
• grill internal prepare-transaction-message, create-sign-tx, create-send-tx and their tests: ReturnType<typeof simulateTransactionFactory> → SimulateTransactionFunction (already exported by gill-extra).
• grill create-send-tx.test.ts: Partial<Parameters<typeof createSendTX>[0]> → Partial<CreateSendTXParams>.
• gill-extra confirm-transaction.test.ts: "processed" | "confirmed" | "finalized" | null → Commitment | null.
• example-dapp token-balances.tsx: ReturnType<typeof address> → Address.

Left alone

• BatchAccountsLoaderConfig.commitment: "confirmed" | "finalized": Commitment would also allow "processed", which widens the public type.
• gill-extra SimulateTransactionConfig / SimulateTransactionFunction, which index into SimulateTransactionApi["simulateTransaction"]: rpc-api doesn't export the config or response types.
• das-api createDasRpc config, Parameters<typeof createDefaultRpcTransport<TClusterUrl>>[0]: DefaultRpcTransportConfig isn't exported from @solana/rpc.
• das-api test Parameters<RpcTransport>[0]: the transport request config type isn't exported from @solana/rpc-spec.
• gill-extra ConfirmedTransaction: derived from our own getConfirmedTransaction, and rpc-api has no named jsonParsed transaction response type.
• grill GillUseQueryDefaultOptions, Parameters<typeof useQuery>[0]: this is TanStack, not Solana, and switching to UseQueryOptions could change how generic defaults resolve.

Summary by Sourcery

Adopt explicit exported types across RPC-related APIs and examples to improve type clarity and maintainability without changing runtime behavior.

Enhancements:

• Replace derived RPC and domain types with explicit named types from the granular Solana and project packages while preserving existing behavior.
• Align transaction simulation, send-transaction parameters, commitment values, and example address types with their exported named definitions.

Build:

• Add @solana/rpc-api and @solana/rpc-spec as peer dependencies for the batch accounts loader.

Reviewer's Guide

This refactor standardizes RPC, transaction, commitment, and address annotations on named exports from the Solana and project packages, including a new explicit RPC API type for the batch accounts loader and its associated peer dependencies. The changes are type-only and should not alter runtime behavior; review primarily for type compatibility, dependency correctness, and preservation of intentionally narrower types.

File-Level Changes

Change	Details	Files
Replace derived RPC and transaction-related types with explicit exported types while preserving runtime behavior and existing shapes.	Declare the batch accounts loader RPC as Rpc. Use SimulateTransactionFunction for injected simulation callbacks in transaction preparation, signing, sending, and tests. Use CreateSendTXParams, Commitment, and Address instead of locally derived or inline types. Add @solana/rpc-api and @solana/rpc-spec as peer dependencies for the batch accounts loader.	packages/solana-batch-accounts-loader/src/types.ts packages/solana-batch-accounts-loader/package.json packages/grill/src/utils/internal/prepare-transaction-message.ts packages/grill/src/utils/internal/prepare-transaction-message.test.ts packages/grill/src/utils/internal/create-sign-tx.ts packages/grill/src/utils/internal/create-sign-tx.test.ts packages/grill/src/utils/internal/create-send-tx.ts packages/grill/src/utils/internal/create-send-tx.test.ts packages/gill-extra/src/confirm-transaction.test.ts apps/example-dapp/src/routes/examples/token-balances.tsx
Update package metadata and lockfile to publish the dependency and versioning changes.	Record a minor release for the batch accounts loader and a patch release for grill. Update resolved dependency data for the new peer dependencies.	.changeset/explicit-rpc-types.md bun.lock
