+  - Refresh only updates the selected evm address
+  - `KeyringController:unlock` no longer starts polling
+  - `AccountsController:accountAdded` no longer updates DeFi positions
+  - `AccountTreeController:selectedAccountGroupChange` updates DeFi positions for the selected address
+  - `TransactionController:transactionConfirmed` only updates DeFi positions if the transaction is for the selected address
