All payments in the Latium Platform are priced in USD (United States Dollar) amounts. Payments can be made using USD or the cryptocurrencies supported by the Latium Platform.
You can price the project in USD and select the cryptocurrency you wish to use to make the payment. Once a contract is created between yourself and a Freelancer that current USD equivalent of that cryptocurrency is locked and awaiting to be paid upon project completion.
Once the project is completed to your specifications you can either select the Pay Now option at the bottom of the contract or the Pay option in the drop down menu
