Wallet setup

To buy CHAR, you will need a web3 wallet set up and connected to the Base or Celo network. The most popular wallet is MetaMask, but you might also consider Coinbase Wallet, Rainbow, or others. Instructions below will cater to MetaMask users.

If you already have MetaMask but have not added Base or Celo, add it by following these steps:

Base setup

1. Navigate to Settings > Networks > Add network

2. Click Add a network manually

3. Copy the following details:

   1. Network Name: Base

   3. Chain ID: 8453

   4. Currency Symbol (Optional): ETH

   5. Block Explorer URL (Optional): https://basescan.org/

4. Click Save

You'll now be able to toggle to the Base network directly from your MetaMask wallet.

Celo setup

Getting assets onto Celo

There are multiple ways to get assets onto the Celo network, including bridging from other blockchains or on-ramping to the Celo network directly. Here we will focus on on-ramping directly to Celo via Coinbase, which is likely to be the easiest path for most users.

How to add assets from Coinbase to Celo

If you are using Coinbase, the most direct way to get assets onto Celo is the following:

1. From Coinbase, purchase Celo's native token, CELO (symbol CGLD). Note that CELO and CGLD are the same token and various platforms use the symbols interchangeably. This token will be used to pay for transactions on the Celo network ("gas fees") and it can also be used to trade for CHAR.

2. With CELO (CGLD) in your Coinbase account, you can then send it to your web3 wallet.

As of March 2024, Coinbase only allows for the withdrawal of CELO (CGLD) directly to the Celo network.
