pub fn encode_create_designated_dealer_script_function(
    currency: TypeTag,
    sliding_nonce: u64,
    addr: AccountAddress,
    auth_key_prefix: Vec<u8, Global>,
    human_name: Vec<u8, Global>,
    add_all_currencies: bool
) -> TransactionPayload

Summary

Creates a Designated Dealer account with the provided information, and initializes it with default mint tiers. The transaction can only be sent by the Treasury Compliance account.

Technical Description

Creates an account with the Designated Dealer role at addr with authentication key auth_key_prefix | addr and a 0 balance of type Currency. If add_all_currencies is true, 0 balances for all available currencies in the system will also be added. This can only be invoked by an account with the TreasuryCompliance role. Authentication keys, prefixes, and how to construct them from an ed25519 public key are described here.

At the time of creation the account is also initialized with default mint tiers of (500_000, 5000_000, 50_000_000, 500_000_000), and preburn areas for each currency that is added to the account.

Events

Successful execution will emit:

• A DiemAccount::CreateAccountEvent with the created field being addr, and the rold_id field being Roles::DESIGNATED_DEALER_ROLE_ID. This is emitted on the DiemAccount::AccountOperationsCapability creation_events handle.
