# Core subpaths

> Every @avokjs/core export subpath, its purpose, and its key exports.

`@avokjs/core` exposes 13 subpaths. Import from the narrowest one that serves your need.

## `@avokjs/core` (`.`)

The browser-wired surface. Exports `createAvokClient(config, wallet)`,
`createOwnOriginConnection({ rpId, operatorName?, storage?, anchorChainId? })`,
`createSharedOriginConnection({ authOrigin, storage? })` (async), `webStorage()`, and the catchable
error classes. See [Errors](/reference/errors).

## `@avokjs/core/engine`

The full framework-agnostic surface, free of browser globals, the React Native base. Exports
`createAvokClient(config)` (core, no announce), `memoryStorage()`, `randomNonceAllocator()`,
`createSequentialNonceAllocator(storage)`, the connection factories, the passkey adapters
(`WebAuthnPasskeyAdapter`, `createReactNativePasskeyAdapter`), `encodeOffchainMessage`, the provider
surface (below), and the error classes.

## `@avokjs/core/provider`

The send/sign surface. Exports:

* `createEip1193Provider(config, opts?): Eip1193Provider`
* `announceEip6963(provider, info): () => void`
* `registerAvokSolanaWallet(config, opts): () => void`
* `WalletInfo` (type)

See [The provider, not hooks](/concepts/provider-not-hooks) for the methods and features.

## `@avokjs/core/wallet`

Wallet primitives: encoding helpers, blob and slot-metadata crypto, the passkey adapters, the
signing verbs (`signMessage`, `signTypedData`, `signSiwe`), the access-vault ABI and call builders
(`buildAddAccessSlotCall`, `buildRemoveAccessSlotCall`), and roster reading. Low-level
key-derivation primitives are deliberately not exported here.

## `@avokjs/core/evm`

The EVM engine types and building blocks: `Receipt`, `Rail`, `ReceiptStatus`, `SimulationResult`,
the `Bundler` and `Paymaster7677` interfaces with `createBundler`/`createPaymaster7677`,
`AvokUserOperation`, the userOp builder, and the chain/token registry re-exports from
`@avokjs/contracts`. See [Receipts](/reference/receipts).

## `@avokjs/core/solana`

The Solana engine types and building blocks: `Receipt`, `Rail`, `ReceiptStatus` (adds `"expired"`),
`SolanaRpcClient` with `createSolanaRpcClient`, `KoraClient` with `createKora`, `KoraRejectedError`,
SPL transfer builders, priority-fee policy, and signers.

## `@avokjs/core/decode`

Solana transaction decoding for consent screens. Exports `decodeCompiledMessage(messageBytes)` and
`classifySplTransfer(ix)`. Refuses messages that use Address Lookup Tables.

## `@avokjs/core/channel`

The client half of the shared-origin channel: the browser and native counterparts that drive the
auth-popup page. Exports `createSharedOriginConnection({ authOrigin, channel, storage? })`,
`createWebChannel({ authOrigin })`, `createNativeChannel({ authOrigin, redirectUri,
openAuthSession })`, `UserRejectedError`, `AuthSessionCancelledError`, and the redirect-protocol
codecs.

## `@avokjs/core/helpers`

Name resolution and send-flow utilities: `createNameResolver`, `createEnsResolver`,
`createSnsResolver`, `resolveRecipient`, balance readers, chain metadata, amount formatting,
explorer URLs, and the QR pairing ceremony runners. See [Resolve names](/guides/resolve-names).

## `@avokjs/core/qr`

The browser QR pairing transport. Exports `createBrowserQrTransport({ qrContainer, video })` and
`CameraUnavailableError`. Requires a secure browser context.

## `@avokjs/core/pairing-window`

A `postMessage` pairing transport for enrolment between two origins on one device. Exports
`createWindowPairingTransport`, `openEnrolmentWindow`, and `enrolmentWindowFromOpener`.

## `@avokjs/core/auth-popup`

The mountable behind the popup page an `rpId` owner hosts. Exports `mountAuthPopup(config, root?)`,
`authPopupDeps(config)`, `runAuthPopup`, `runAuthRedirect`, `resolveAppConfig`, and
`MissingRpIdError`. See [Host the auth popup](/guides/host-auth-popup).

## `@avokjs/core/internal`

A cross-package seam consumed by the provider layer: `createSendEngine`, `createSolanaEngine`, and
the `SendEngine`/`SolanaEngine` types. This is not application API; use the provider instead.
