Creates a Child VASP account with its parent being the sending account of the transaction. The sender of the transaction must be a Parent VASP account.

Technical Description

Creates a ChildVASP account for the sender parent_vasp at child_address with a balance of child_initial_balance in CoinType and an initial authentication key of auth_key_prefix | child_address.

If add_all_currencies is true, the child address will have a zero balance in all available currencies in the system.

The new account will be a child account of the transaction sender, which must be a Parent VASP account. The child account will be recorded against the limit of child accounts of the creating Parent VASP account.


Successful execution with a child_initial_balance greater than zero will emit:


CoinTypeTypeThe Move type for the CoinType that the child account should be created with. CoinType must be an already-registered currency on-chain.
parent_vasp&signerThe signer reference of the sending account. Must be a Parent VASP account.
child_addressaddressAddress of the to-be-created Child VASP account.
