Using chains and currencies in the API

Any time you refer to a currency in a Circle Mint API call, you use a currency and chain pair. For example, to create a USDC transfer on Ethereum, specify the USD currency on the ETH chain. When referring to balances, you only need to refer to the currency because the value of the currency for Circle-hosted assets is independent of the chain.
