EIN - EIN Transfer

Once an EIN has set an Allowance for a Resolver, the Resolver may directly initiate transfers on behalf of the EIN. To transfer HYDRO from one EIN to another using an EIN’s Allowance, call transferSnowflakeBalanceFrom with the arguments defined below. Critically, this function is called by the DApp, meaning the DApp can enforce any desired permissions on initiating the transaction, including a meta-transaction scheme.
