 ## [Unreleased]
 
+### Changed
+
+- **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
+
 ## [64.3.0]
