Mints a specified number of coins in a currency to a Designated Dealer. The sending account must be the Treasury Compliance account, and coins can only be minted to a Designated Dealer account.

Technical Description

Mints mint_amount of coins in the CoinType currency to Designated Dealer account at designated_dealer_address. The tier_index parameter specifies which tier should be used to check verify the off-chain approval policy, and is based in part on the on-chain tier values for the specific Designated Dealer, and the number of CoinType coins that have been minted to the dealer over the past 24 hours. Every Designated Dealer has 4 tiers for each currency that they support. The sending tc_account must be the Treasury Compliance account, and the receiver an authorized Designated Dealer account.


Successful execution of the transaction will emit two events:


CoinTypeTypeThe Move type for the CoinType being minted. CoinType must be an already-registered currency on-chain.
