# Resolver - EIN Transfer

All Resolvers inherit the ability to directly transfer HYDRO balances to EINs.

Any Resolver maintaining a HYDRO token balance may call `transferHydroBalanceTo` with a target `EIN` and an amount to send HYDRO to an `EIN`.

Note, one common pattern is to immediately escrow an entire allowance once it is set.

`transferHydroBalanceTo` Function should follow the example format:

**ARGUMENTS**

| Parameter | Type   | Description                        |
| --------- | ------ | ---------------------------------- |
| `einTo`   | `uint` | `EIN` of recipient.                |
| `amount`  | `uint` | Amount of HYDRO to be transferred. |
