# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [13.0.0]

### Changed

- Bump `@metamask/accounts-controller` from `^39.0.4` to `^39.0.5` ([#9470](https://github.com/MetaMask/core/pull/9470))

### Removed

- **BREAKING:** Removed use of v1 `createAccount` entirely ([#9460](https://github.com/MetaMask/core/pull/9460))
  - All BIP-44 Snaps are expected to implement `createAccounts` (v1 or v2).
  - The old v1 `createAccount` flow had some undesired side-effetcs sometimes (e.g auto-selecting a non-EVM account after being created, which is not compatible with our new group model).

## [12.0.0]

### Added

- Capability-gated v1/v2 keyring client selection for Snap account providers ([#9377](https://github.com/MetaMask/core/pull/9377))
  - Providers resolve a Snap's capabilities via `SnapAccountService:getCapabilities` and route account creation and discovery through the v1 or v2 keyring client accordingly (a Snap that declares BIP-44 capabilities is treated as v2).
  - Account discovery for v2 Snaps that declare `bip44.discover` flows through `createAccounts({ bip44:discover })`; v1 Snaps keep using the `discoverAccounts` client method.
- Adds `MultichainAccountGroup.isProviderAligned(provider)` to check alignment per provider ([#9269](https://github.com/MetaMask/core/pull/9269))

### Changed

- **BREAKING:** Remove `batched` from `SnapAccountProviderConfig['createAccounts']` ([#9377](https://github.com/MetaMask/core/pull/9377))
  - Batching is now derived from the Snap's capabilities (v2 Snaps that declare `bip44` use the `createAccounts` flow, since they expose no singular `createAccount`) instead of static config.
- **BREAKING:** Now requires `SnapAccountService:getCapabilities` action ([#9377](https://github.com/MetaMask/core/pull/9377))
- **BREAKING:** `RestrictedSnapKeyring.createAccount` has been replaced by `RestrictedSnapKeyring.v1`, which is `undefined` for v2-only Snaps ([#9390](https://github.com/MetaMask/core/pull/9390))
  - Any subclass implementing `SnapAccountProvider.createAccountV1` must now check `keyring.v1` guard followed by `keyring.v1.createAccount(options)`.
- Wallet alignment now only creates the missing `(provider, group index)` pairs instead of re-creating the whole range for every provider, avoiding redundant `createAccounts` calls (and their traces) ([#9269](https://github.com/MetaMask/core/pull/9269))
- Bump `@metamask/accounts-controller` from `^39.0.3` to `^39.0.4` ([#9349](https://github.com/MetaMask/core/pull/9349))
- Bump `@metamask/messenger` from `^1.2.0` to `^2.0.0` ([#9392](https://github.com/MetaMask/core/pull/9392))
- Bump `@metamask/eth-snap-keyring` from `^22.3.0` to `^23.0.0` ([#9390](https://github.com/MetaMask/core/pull/9390))
- Bump `@metamask/keyring-api` from `^23.3.0` to `^23.5.0` ([#9390](https://github.com/MetaMask/core/pull/9390))
- Bump `@metamask/keyring-snap-client` from `^9.0.2` to `^9.2.0` ([#9390](https://github.com/MetaMask/core/pull/9390))
- Bump `@metamask/snap-account-service` from `^1.0.0` to `^2.0.0` ([#9429](https://github.com/MetaMask/core/pull/9429))

## [11.1.0]

### Added

- Add `XlmAccountProvider` for Stellar account support ([#8830](https://github.com/MetaMask/core/pull/8830))
  - Export `XlmAccountProvider`, `XLM_ACCOUNT_PROVIDER_NAME`, and `XlmAccountProviderConfig`.

### Changed

- Bump `@metamask/keyring-api` from `^23.1.0` to `^23.3.0` ([#9249](https://github.com/MetaMask/core/pull/9249))
- Bump `@metamask/keyring-utils` from `^3.2.1` to `^3.3.1` ([#9249](https://github.com/MetaMask/core/pull/9249))

## [11.0.0]

### Added

- Added `Bip44AccountProvider.deleteAccount(id)` method ([#8960](https://github.com/MetaMask/core/pull/8960))
  - The `KeyringController` will automatically prunes the non-primary empty keyrings when the last EVM account is getting removed.
  - `AccountProviderWrapper.deleteAccount(id)` always removes the account, even if disabled.
- Added `AccountProviderWrapper.unwrap` method ([#8960](https://github.com/MetaMask/core/pull/8960))
  - Use this if you need to access the inner (wrapped) keyring.
- Add `isAligned` ([#9039](https://github.com/MetaMask/core/pull/9039))
  - This allows callers to cheaply check whether alignment has already occurred before triggering an explicit alignment operation.

### Changed

- **BREAKING:** Replace `KeyringController:withKeyring` with `KeyringController:withKeyringV2` for the Snap account providers ([#8732](https://github.com/MetaMask/core/pull/8732))
- Bump `@metamask/eth-snap-keyring` from `^22.0.1` to `^22.3.0` ([#8732](https://github.com/MetaMask/core/pull/8732))
- **BREAKING:** `MultichainAccountService.removeMultichainAccountWallet` (and messenger action) now takes a single `entropySource` argument ([#8960](https://github.com/MetaMask/core/pull/8960))
  - The previous `accountAddress` parameter has been removed.
  - All accounts are now unconditionally removed from the wallet and providers (even for disabled `AccountProviderWrapper`).
  - Per-account deletions are best-effort: a single account's failure does not abort cleanup of the remaining accounts.
  - Errors are aggregated and reported in case of failure.
- Bump `@metamask/utils` from `^11.9.0` to `^11.11.0` ([#9074](https://github.com/MetaMask/core/pull/9074))

## [10.0.0]

### Changed

- **BREAKING:** The service messenger now requires the `SnapAccountService:ensureReady` action to be declared ([#8715](https://github.com/MetaMask/core/pull/8715))
- **BREAKING:** Delegate Snap platform readiness to `@metamask/snap-account-service` ([#8715](https://github.com/MetaMask/core/pull/8715), [#8752](https://github.com/MetaMask/core/pull/8752))
  - Removed `MultichainAccountService.ensureCanUseSnapPlatform()` method and the corresponding `MultichainAccountService:ensureCanUseSnapPlatform` messenger action.
  - Removed the `MultichainAccountServiceEnsureCanUseSnapPlatformAction` type export.
  - Removed `MultichainAccountServiceOptions.ensureOnboardingComplete`. Configure it via `SnapAccountService`'s `config.snapPlatformWatcher.ensureOnboardingComplete` instead.
  - Removed `MultichainAccountServiceConfig.snapPlatformWatcher` and the `SnapPlatformWatcherConfig` type export. Configure the keyring-wait timeout via `SnapAccountService`'s `config.snapPlatformWatcher.snapKeyringWaitTimeoutMs` instead.
  - The service messenger no longer needs `SnapController:getState`, `SnapController:stateChange` or `KeyringController:stateChange`.
- **BREAKING:** Rename `SnapAccountProvider.ensureCanUseSnapPlatform()` to `ensureReady()` ([#8715](https://github.com/MetaMask/core/pull/8715))
- Bump `@metamask/accounts-controller` from `^38.0.0` to `^38.1.1` ([#8755](https://github.com/MetaMask/core/pull/8755), [#8774](https://github.com/MetaMask/core/pull/8774))

  - Corresponding action type is available as well.
- Filter out `KeyringController` locked errors from sentry reporting ([#8619](https://github.com/MetaMask/core/pull/8619))

- Bump `@metamask/accounts-controller` from `^37.1.1` to `^38.0.0` ([#8363](https://github.com/MetaMask/core/pull/8363), [#8665](https://github.com/MetaMask/core/pull/8665))
- Bump `@metamask/keyring-controller` from `^25.1.1` to `^25.5.0` ([#8363](https://github.com/MetaMask/core/pull/8363), [#8634](https://github.com/MetaMask/core/pull/8634), [#8665](https://github.com/MetaMask/core/pull/8665), [#8722](https://github.com/MetaMask/core/pull/8722))
- Bump `@metamask/messenger` from `^1.0.0` to `^1.2.0` ([#8364](https://github.com/MetaMask/core/pull/8364), [#8373](https://github.com/MetaMask/core/pull/8373), [#8632](https://github.com/MetaMask/core/pull/8632))
- Bump `@metamask/base-controller` from `^9.0.1` to `^9.1.0` ([#8457](https://github.com/MetaMask/core/pull/8457))

- Bump `@metamask/snaps-sdk` from `^10.3.0` to `^11.0.0` ([#8319](https://github.com/MetaMask/core/pull/8319))
- Bump `@metamask/snaps-utils` from `^11.7.0` to `^12.1.2` ([#8319](https://github.com/MetaMask/core/pull/8319))
- Bump `@metamask/accounts-controller` from `^37.1.0` to `^37.1.1` ([#8325](https://github.com/MetaMask/core/pull/8325))

## [8.0.0]

### Added

- Use `{Btc,Sol}AccountProvider` as default providers ([#8262](https://github.com/MetaMask/core/pull/8262))
  - Those providers were initially provided by the clients.
- Add new `createMultichainAccountGroups` support to create multiple groups in batch ([#7801](https://github.com/MetaMask/core/pull/7801), [#8190](https://github.com/MetaMask/core/pull/8190))
- Add new `resyncAccounts.autoRemoveExtraSnapAccounts` configuration on Snap-based providers ([#8200](https://github.com/MetaMask/core/pull/8200))
  - When enabled, this will make the `resyncAccounts` method automatically remove any extra accounts that exist on the Snap side but not on MetaMask side.
  - This behavior was enabled by default and can now be turned off by the clients.
- Add new `snapPlatformWatcher.timeoutMs` configuration ([#8196](https://github.com/MetaMask/core/pull/8196))
  - Allows configuring how long to wait for the Snap keyring to appear in `KeyringController` before timing out (Default is 5000 ms).
- Add more tracing (alignment, create account v1/v2) ([#8244](https://github.com/MetaMask/core/pull/8244))
- Add local perf tracing ([#8244](https://github.com/MetaMask/core/pull/8244))
  - Each trace is now automatically wrapped and will log performance timings using the internal logger.
  - Only enabled if `metamask:multichain-account-service` is part of `DEBUG` (env var) filters.

### Changed

- Bump `@metamask/accounts-controller` from `^37.0.0` to `^37.1.0` ([#8317](https://github.com/MetaMask/core/pull/8317))
- Bump `@metamask/base-controller` from `^9.0.0` to `^9.0.1` ([#8317](https://github.com/MetaMask/core/pull/8317))
- Bump `@metamask/keyring-controller` from `^25.1.0` to `^25.1.1` ([#8317](https://github.com/MetaMask/core/pull/8317))
- Bump `@metamask/messenger` from `^0.3.0` to `^1.0.0` ([#8317](https://github.com/MetaMask/core/pull/8317))
- Bump `@metamask/keyring-api` from `^21.5.0` to `^21.6.0` ([#8259](https://github.com/MetaMask/core/pull/8259))
- Optimize `{Sol,Btc,Trx}AccountProvider.createAccounts` for range operations ([#8131](https://github.com/MetaMask/core/pull/8131))
  - Each Snaps have to implement the new `keyring_createAccounts` method accordingly and enable the batch option using the provider's configuration object.
  - Batch account creation with the new `SnapKeyring.createAccounts` method.
  - Significantly reduces lock acquisitions and API calls for batch operations.
- Optimize `EvmAccountProvider.createAccounts` for range operations ([#7801](https://github.com/MetaMask/core/pull/7801))
  - Batch account creation with single a `withKeyring` call for entire range instead of one call per account.
  - Batch account creation with single `keyring.addAccounts` call.
  - Fetch all accounts in single `AccountsController:getAccounts` call instead of multiple `getAccount` calls.
  - Significantly reduces lock acquisitions and API calls for batch operations.
- Do not report `TimeoutError` errors ([#8249](https://github.com/MetaMask/core/pull/8249))
  - All other kind of errors are still reported as usual.

### Removed

- **BREAKING:** Remove `MultichainAccountGroup.alignAccounts` method ([#7801](https://github.com/MetaMask/core/pull/7801))
  - Use `MultichainAccountWallet.alignAccountsOf` instead, since this method properly lock the wallet (parent of this group) state.

### Fixed

- Prevent wallet's lock by-pass when creating non-EVM account asynchronously ([#7801](https://github.com/MetaMask/core/pull/7801))
  - The `waitForAllProvidersToFinishCreatingAccounts` option (when set to `false`) was causing account creation to be asynchronous for non-EVM providers, which was potentially creating accounts after the wallet's internal lock was released.
  - We now run an internal account alignment operation which locks the wallet properly and runs in the background.
- Wait for Snap keyring in KeyringController before non-EVM account creation ([#8196](https://github.com/MetaMask/core/pull/8196))
  - After wallet reset or restore, the Snap keyring is created lazily (e.g. when `getSnapKeyring()` runs). We now wait for it to appear (via `KeyringController:getState` and `KeyringController:stateChange`) with a timeout, avoiding "Keyring not found" error.

## [7.1.0]

### Added

- Add new optional `ensureOnboardingComplete` callback ([#8124](https://github.com/MetaMask/core/pull/8124))
  - This allows the service to wait for the user to re-onboard after a wallet reset.

### Changed

- Bump `@metamask/accounts-controller` from `^36.0.0` to `^37.0.0` ([#7996](https://github.com/MetaMask/core/pull/7996), [#8140](https://github.com/MetaMask/core/pull/8140))

## [7.0.0]

### Changed

- **BREAKING:** Bump peer dependency `@metamask/account-api` from `^0.12.0` to `^1.0.0` ([#7857](https://github.com/MetaMask/core/pull/7857))
- **BREAKING:** Bump `@metamask/eth-snap-keyring` from `^18.0.0` to `^19.0.0` ([#7857](https://github.com/MetaMask/core/pull/7857))
  - Required to invoke `createAccounts` on any account management Snaps.
- **BREAKING:** Use new `AccountProvider.createAccounts` method with `CreateAccountOptions` ([#7857](https://github.com/MetaMask/core/pull/7857))
  - All account providers now accept `CreateAccountOptions` with `type` field.
  - Added `capabilities` property to all account providers defining supported account creation types.
- Bump `@metamask/accounts-controller` from `^35.0.2` to `^36.0.0` ([#7897](https://github.com/MetaMask/core/pull/7897))
- Bump `@metamask/keyring-api` from `^21.0.0` to `^21.5.0` ([#7857](https://github.com/MetaMask/core/pull/7857))
- Bump `@metamask/keyring-internal-api` from `^9.0.0` to `^10.0.0` ([#7857](https://github.com/MetaMask/core/pull/7857))
- Bump `@metamask/keyring-snap-client` from `^8.0.0` to `^8.2.0` ([#7857](https://github.com/MetaMask/core/pull/7857))

## [6.0.0]

### Changed

- **BREAKING** A performance refactor was made around all the classes in this package ([#6654](https://github.com/MetaMask/core/pull/6654))
  - The `MultichainAccountService` is refactored to construct a top level service state for its `init` function, this state is passed down to the `MultichainAccountWallet` and `MultichainAccountGroup` classes in slices for them to construct their internal states.
  - Additional state is generated at the entry points where it needs to be updated i.e. `createMultichainAccountGroup`, `discoverAccounts` and `alignAccounts`.
  - We no longer prevent group creation if some providers' `createAccounts` calls fail during group creation, only if they all fail.
  - The `getAccounts` method in the `BaseBip44AccountProvider` class no longer relies on fetching the entire list of internal accounts from the `AccountsController`, instead it gets the specific accounts that it stores in its internal accounts list.
  - The `EvmAccountProvider` no longer fetches from the `AccountController` to get an account for its ID, we deterministically get the associated account ID through `getUUIDFromAddressOfNormalAccount`.
  - The `EvmAccountProvider` now uses the `getAccount` method from the `AccountsController` when fetching an account after account creation as it is more efficient.
  - Add logic in the `createMultichainAccountWallet` method in `MultichainAccountService` so that it can handle all entry points: importing an SRP, recovering a vault and creating a new vault.
  - Add a `getAccountIds` method which returns all the account ids pertaining to a group.
  - Add an `addAccounts` method on the `BaseBip44AccountProvider` class which keeps track of all the account IDs that pertain to it.
- Bump `@metamask/keyring-controller` from `^25.0.0` to `^25.1.0` ([#7713](https://github.com/MetaMask/core/pull/7713))

### Removed

- **BREAKING** A performance refactor was made around all the classes in this package ([#6654](https://github.com/MetaMask/core/pull/6654))
  - Remove `#handleOnAccountAdded` and `#handleOnAccountRemoved` methods in `MultichainAccountService` due to internal state being updated within the service.
  - Remove `getAccountContext` (and associated map) in the `MultichainAccountService` as the service no longer uses that method.
  - Remove the `sync` method in favor of the sole `init` method for both `MultichainAccountWallet` and `MultichainAccountGroup`.

## [5.1.0]

### Added

- Recover from Snap account de-sync when Snap has more accounts than MetaMask ([#7671](https://github.com/MetaMask/core/pull/7671))

### Changed

- Bump `@metamask/accounts-controller` from `^35.0.0` to `^35.0.2` ([#7604](https://github.com/MetaMask/core/pull/7604), [#7642](https://github.com/MetaMask/core/pull/7642))
- Remove Sentry log before attempting Snap account re-sync ([#7675](https://github.com/MetaMask/core/pull/7675))

## [5.0.0]

### Added

- Wait for Snap platform to be ready before any wallet/group operations ([#7266](https://github.com/MetaMask/core/pull/7266))
- Add `SnapAccountProvider.withSnap` protected helper ([#7266](https://github.com/MetaMask/core/pull/7266))
  - This is used to protect any Snap operation behind a guard that checks if the Snap platform is ready.
- Add `MultichainAccountService:ensureCanUseSnapPlatform` method and action.
  - This will resolve once the Snap platform is ready for the first time and will throw afterward if Snap platform has been disabled dynamically.
  - This action is mostly used internally by any Snap-based account providers.

### Changed

- **BREAKING:** The `SnapAccountProvider.client` property is now private ([#7266](https://github.com/MetaMask/core/pull/7266))
  - You now need to use `SnapAccountProvider.withSnap` to access to it.
- Bump `@metamask/snaps-controllers` from `^14.0.1` to `^17.2.0` ([#7550](https://github.com/MetaMask/core/pull/7550))
- Bump `@metamask/snaps-sdk` from `^9.0.0` to `^10.3.0` ([#7550](https://github.com/MetaMask/core/pull/7550))
- Bump `@metamask/snaps-utils` from `^11.0.0` to `^11.7.0` ([#7550](https://github.com/MetaMask/core/pull/7550))
- Upgrade `@metamask/utils` from `^11.8.1` to `^11.9.0` ([#7511](https://github.com/MetaMask/core/pull/7511))
- Remove dependency on `@metamask/error-reporting-service` ([#7542](https://github.com/MetaMask/core/pull/7542))
  - The service no longer needs `ErrorReportingService:captureException`.

## [4.1.0]

### Added

- Add `config.discovery.enabled` option for all account provider config objects ([#7447](https://github.com/MetaMask/core/pull/7447))
- Add `{EVM,SOL,BTC,TRX}_ACCOUNT_PROVIDER_DEFAULT_CONFIG` ([#7447](https://github.com/MetaMask/core/pull/7447))

## [4.0.1]

### Changed

- Move peer dependencies for controller and service packages to direct dependencies ([#7209](https://github.com/MetaMask/core/pull/7209))
  - The dependencies moved are:
    - `@metamask/accounts-controller` (^35.0.0)
    - `@metamask/error-reporting-service` (^3.0.0)
    - `@metamask/keyring-controller` (^25.0.0)
    - `@metamask/snaps-controllers` (^14.0.1)
  - In clients, it is now possible for multiple versions of these packages to exist in the dependency tree.
    - For example, this scenario would be valid: a client relies on `@metamask/controller-a` 1.0.0 and `@metamask/controller-b` 1.0.0, and `@metamask/controller-b` depends on `@metamask/controller-a` 1.1.0.
  - Note, however, that the versions specified in the client's `package.json` always "win", and you are expected to keep them up to date so as not to break controller and service intercommunication.

### Fixed

- Harden EVM discovery in case of bad RPC response ([#7434](https://github.com/MetaMask/core/pull/7434))
  - If the response was not hex-formatted, then the EVM discovery was continuously running.

## [4.0.0]

### Changed

- **BREAKING:** Bump `@metamask/keyring-controller` from `^24.0.0` to `^25.0.0` ([#7202](https://github.com/MetaMask/core/pull/7202))
- **BREAKING:** Bump `@metamask/accounts-controller` from `^34.0.0` to `^35.0.0` ([#7202](https://github.com/MetaMask/core/pull/7202))

## [3.0.0]

### Added

- **BREAKING:** Added error reporting around account creation with the `ErrorReportingService` ([#7044](https://github.com/MetaMask/core/pull/7044))
  - The `@metamask/error-reporting-service` is now a peer dependency.
- Add `MultichainAccountService.resyncAccounts` method and action ([#7087](https://github.com/MetaMask/core/pull/7087), [#7093](https://github.com/MetaMask/core/pull/7093))
- Add `*AccountProvider.resyncAccounts` method ([#7087](https://github.com/MetaMask/core/pull/7087))

### Changed

- **BREAKING:** Make `init` method `async` ([#7087](https://github.com/MetaMask/core/pull/7087))
  - While this is not yet really used, we might want to make some `async` calls (like `resyncAccounts`) in `init` directly at some point.
- Add optional tracing configuration ([#7006](https://github.com/MetaMask/core/pull/7006))
  - For now, only the account discovery is being traced.
- Limit Bitcoin and Tron providers to 3 concurrent account creations by default when creating multichain account groups ([#7052](https://github.com/MetaMask/core/pull/7052))

## [2.1.0]

### Added

- Add per-provider throttling for non-EVM account creation to improve performance on low-end devices ([#7000](https://github.com/MetaMask/core/pull/7000))
  - Solana provider is now limited to 3 concurrent account creations by default when creating multichain account groups.
  - Other providers remain unthrottled by default.

## [2.0.1]

### Fixed

- Use `groupIndex` for account creations on `TrxAccountProvider` instead of the outdated `derivationPath` ([#7010](https://github.com/MetaMask/core/pull/7010), [#7018](https://github.com/MetaMask/core/pull/7018))

## [2.0.0]

### Changed

- **BREAKING:** Use new `Messenger` from `@metamask/messenger` ([#6544](https://github.com/MetaMask/core/pull/6544))
  - Previously, `MultichainAccountService` accepted a `RestrictedMessenger` instance from `@metamask/base-controller`.
- **BREAKING:** Bump `@metamask/accounts-controller` from `^33.0.0` to `^34.0.0` ([#6962](https://github.com/MetaMask/core/pull/6962))

## [1.6.2]

### Changed

- Bump `@metamask/base-controller` from `^8.4.1` to `^8.4.2` ([#6917](https://github.com/MetaMask/core/pull/6917))

### Changed

- Bump `@metamask/base-controller` from `^8.4.0` to `^8.4.1` ([#6807](https://github.com/MetaMask/core/pull/6807))

## [1.6.0]

### Changed

- Update Bitcoin account provider to only create/discover Native SegWit (P2wpkh) accounts ([#6783](https://github.com/MetaMask/core/pull/6783))

## [1.5.0]

### Added

- Add an optional `options` parameter to `MultichainAccountWallet.createMultichainAccountGroup()` ([#6759](https://github.com/MetaMask/core/pull/6759))
  - Introduces `options.waitForAllProvidersToFinishCreatingAccounts`, that will make `createMultichainAccountGroup` await either only the EVM provider or all the providers to have created their accounts depending on the value. Defaults to `false` (only awaits for EVM accounts creation by default).

## [1.4.0]

### Changed

- Only await for EVM account creation in `MultichainAccountWallet.createMultichainAccountGroup()` instead of all types of providers ([#6755](https://github.com/MetaMask/core/pull/6755))
  - Other type of providers will create accounts in the background and won't throw errors in case they fail to do so.
  - Multichain account groups will now be "misaligned" for a short period of time, until each of the other providers finish creating their accounts.

## [1.3.0]

### Added

- Add `{Btc/Trx}AccountProvider` account providers ([#6662](https://github.com/MetaMask/core/pull/6662))

### Changed

- Bump `@metamask/utils` from `^11.8.0` to `^11.8.1` ([#6708](https://github.com/MetaMask/core/pull/6708))

## [1.2.0]

### Changed

- Add more internal logs ([#6729](https://github.com/MetaMask/core/pull/6729))

## [1.1.0]

### Added

- Add a timeout around Solana account creation ([#6704](https://github.com/MetaMask/core/pull/6704))
  - This timeout can be configured at the client level through the config passed to the `MultichainAccountService`.

## [1.0.0]

### Changed

- Bump package version to v1.0 to mark stabilization ([#6676](https://github.com/MetaMask/core/pull/6676))

## [0.11.0]

### Added

- Add missing exports for providers (`{EVM,SOL}_ACCOUNT_PROVIDER_NAME` + `${Evm,Sol}AccountProvider}`) ([#6660](https://github.com/MetaMask/core/pull/6660))
  - These are required when setting the new account providers when constructing the service.

## [0.10.0]

### Added

- Add timeout and retry mechanism to Solana discovery ([#6624](https://github.com/MetaMask/core/pull/6624))
- Add custom account provider configs ([#6624](https://github.com/MetaMask/core/pull/6624))
  - This new config can be set by the clients to update discovery timeout/retry values.

### Fixed

- No longer create temporary EVM account during discovery ([#6650](https://github.com/MetaMask/core/pull/6650))
  - We used to create the EVM account and remove it if there was no activity for that account. Now we're just deriving the next address directly, which avoids state mutation.
  - This prevents `:accountAdded` event from being published, which also prevents account-tree and multichain-account service updates.
  - Backup & sync will no longer synchronize this temporary account group, which was causing a bug that persisted it on the user profile and left it permanently.

## [0.9.0]

### Added

- **BREAKING** Add additional allowed actions to the `MultichainAccountService` messenger
  - `KeyringController:getKeyringsByType` and `KeyringController:addNewKeyring` actions were added.
- Add `createMultichainAccountWallet` method to create a new multichain account wallet from a mnemonic ([#6478](https://github.com/MetaMask/core/pull/6478))
  - An action handler was also registered for this method so that it can be called from the clients.

### Changed

- Bump `@metamask/utils` from `^11.4.2` to `^11.8.0` ([#6588](https://github.com/MetaMask/core/pull/6588))
- Bump `@metamask/base-controller` from `^8.3.0` to `^8.4.0` ([#6632](https://github.com/MetaMask/core/pull/6632))

## [0.8.0]

### Added

- Add mutable operation lock (per wallets) ([#6527](https://github.com/MetaMask/core/pull/6527))
  - Operations such as discovery, alignment, group creation will now lock an internal mutex (per wallets).
- Add wallet status tracking with `:walletStatusChange` event ([#6527](https://github.com/MetaMask/core/pull/6527))
  - This can be used to track what's the current status of a wallet (e.g. which operation is currently running OR if the wallet is ready to run any new operations).
- Add `MultichainAccountWalletStatus` enum ([#6527](https://github.com/MetaMask/core/pull/6527))
  - Enumeration of all possible wallet statuses.

### Added

- Add `discoverAndCreateAccounts` methods for EVM and Solana providers ([#6397](https://github.com/MetaMask/core/pull/6397))
- Add `discoverAndCreateAccounts` method to `MultichainAccountWallet` to orchestrate provider discovery ([#6397](https://github.com/MetaMask/core/pull/6397))

  - You can now pass an extra option `providers` in the service's constructor.
- Add multichain account group creation support ([#6222](https://github.com/MetaMask/core/pull/6222), [#6238](https://github.com/MetaMask/core/pull/6238), [#6240](https://github.com/MetaMask/core/pull/6240))
