# EIN - Via - EIN Transfer

For `EIN`-`EIN` transfers that use a `via` contract, call `transferSnowflakeBalanceFromVia` with the arguments defined below. The first four argument are requirements for a `via` contract as seen in the Building a Via section. The `bytes` argument is accepted by the `snowflakeCall` function of the `via` Contract and allows arbitrary data to flow to the `Via` from the  Resolver. These arguments are standardized and recognized in the interface of all `via` contracts.
