fix: Fix hardware wallet MMPay on EIP-7702 chains by gating 7702 paths on account keyring capability

packages/transaction-controller/CHANGELOG.md

@@ -11,16 +11,25 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 - Expose `TransactionController:wipeTransactions` method through `TransactionController` messenger ([#8592](https://github.com/MetaMask/core/pull/8592))
 
+### Changed
+
+- `estimateGasBatch` now skips the EIP-7702 path when the account's keyring does not support it, falling back to per-transaction gas estimation ([#8388](https://github.com/MetaMask/core/pull/8388))
+- `doesAccountSupportEIP7702` now returns `false` instead of `true` when the account is not found in any keyring ([#8388](https://github.com/MetaMask/core/pull/8388))
+
 ## [64.4.0]
 
 ### Changed
 
 - Snapshot `txParamsOriginal` in `updateEditableParams` when `containerTypes` are first applied ([#8546](https://github.com/MetaMask/core/pull/8546))
 - Add `requiresAuthorizationList` to `TransactionController:estimateGasBatch` results when EIP-7702 batch gas estimation requires a first-time account upgrade ([#8577](https://github.com/MetaMask/core/pull/8577))
+- **BREAKING:** Add `KeyringControllerGetStateAction` to `AllowedActions` to enable keyring-based EIP-7702 account compatibility checks in `addTransactionBatch` ([#8388](https://github.com/MetaMask/core/pull/8388))
+  - `addTransactionBatch` now automatically checks whether the account's keyring supports EIP-7702 before attempting the 7702 batch path, falling back to STX/sequential when unsupported
+  - Clients must add `KeyringController:getState` to the TransactionController messenger's allowed actions
 
 ### Fixed
 
 - Gas estimation for EIP-7702 transactions now supports any upgrade-with-data transaction, not only self-targeted ones ([#8467](https://github.com/MetaMask/core/pull/8467))
+- Fix batch transaction signing so each transaction is signed sequentially, preventing remaining hardware wallet prompts from appearing after a rejection ([#8388](https://github.com/MetaMask/core/pull/8388))
