-You might be wondering why the type is defined as "open_zeppelin" even though we're working with a Braavos wallet. This is because the CLI uses Open Zeppelin's default algorithm to sign transactions, which happens to be the same one used by Braavos and Argent X by default.
-
-However, note that a Braavos smart wallet with a hardware signer enabled will not work in this context, as a hardware signer uses a different elliptic curve to sign transactions.
+If you are working with Braavos wallet, the type is defined as "braavos" and the account descriptor strcuture might be slightly different.
