Trait functions

execute_meta_tx_v0

Wrapper around the meta_tx_v0_syscall function.

Invokes the given entry point as a v0 meta transaction.

• The signature is replaced with the given signature.
• The caller is the OS (address 0).
• The transaction version is replaced by 0.
• The transaction hash is replaced by the corresponding version-0 transaction hash.

The context changes apply to the called contract and the inner contracts it calls, except for the caller, which is updated appropriately in subcalls.

NOTE: This syscall should only be used to allow support for old version-0 bound accounts, and should not be used for other purposes.
