The Kinesis Mint is a platform that allows users to create (Mint) their own Kinesis gold (KAU) and silver (KAG) currencies into existence by depositing either fiat, cryptocurrency or physical bullion.
As the mint only deals in USD fiat currency, any other fiat or crypto will be converted by Kinesis to a USD balance prior to you being able to mint.
Additionally, the Exchange Physical for Digital (EPD) process allows KAU and KAG to be created from deposited gold and silver. You can find more information in the article about EPD here.
