Buying, transfering/bridging and getting your CUDOS token (coin) involves a few steps. There are Cudos ERC-20 tokens on the Ethereum blockchain and CUDOS token on the CUDOS network. Since the launch of the Cudos mainnet you can now transfer CUDOS tokens from Ethereum to Cudos mainnet, and vice versa.

## Prerequisite:

- Ethereum account on [Metamask](https://metamask.io/download/).
- Cudos account on Keplr wallet. Follow this [written guide](https://docs.cudos.org/build/account-setup.html#what-is-keplr) on how to open a Cudos account on Keplr. You can watch [this tutorial](https://www.youtube.com/watch?v=j7wd1AI2tDY) if you prefer video.

These are the essentials you need to get CUDOS. Now let’s dive into the specifics of how to get your CUDOS tokens.
