# How to deposit CRO for zkCRO

zkCRO can be used across the Cronos zkEVM ecosystem. Apart from using it to pay gas fees, you can also earn yield just by holding it. Depositing CRO also earns you points in the [pioneer program](https://blog.cronos.org/p/announcing-the-cronos-zkevm-pioneer).

## Before depositing CRO via the bridge

First, you need to hold CRO on Ethereum. You can purchase CRO via one of the following ways:

1. Swap on [Uniswap](https://app.uniswap.org/swap)
2. Buy on a centralized exchange and withdraw to Ethereum

## Bridging CRO from Ethereum to Cronos zkEVM

1\. Head to <https://zkevm.cronos.org> and connect your wallet.
