Overview​

  1. Create a wallet.
  2. Complete the KYC verification process.
  3. Request funds from the Discord faucet.
  4. Perform a cross-chain transfer between the X-Chain and C-Chain.
  5. Add your account and the Columbus network to the MetaMask wallet.
  6. Access the Remix IDE & Import a sample ERC20 contract.
  7. Compile the contract.
  8. Provide the necessary details and deploy the contract.
  9. Add your newly created token to MetaMask and the Camino Wallet.

1. Create a Wallet​

To create a Camino Wallet, please follow the instructions provided in the How to Create a Wallet documentation page.

If you already have a wallet, you can proceed to the next step.

2. KYC Verification​

Ensure that your account is KYC-verified. To complete the KYC verification process, refer to the KYC Verification documentation page.

If your account is already KYC-verified, you can skip this step.

3. Request Funds from the Discord Faucet​

To request funds from the Discord faucet, visit the Camino Discord server and follow the instructions below.

To request funds from the Discord faucet, follow these steps:

  1. Join the Camino Discord server and navigate to the Community > General channel.
  2. Type /faucet in the chat. The user interface will update to reflect the changes, similar to the screenshot provided.
  3. Copy and paste your X-Address from the Camino Wallet.
  4. Enter the amount of CAM you wish to request, separating the command, X-Address and the requested amount with spaces.

Please note that there is a limit of 150 CAM that can be requested within a 1-week period.

FAUCET LIMIT

The daily faucet limit is subject to change. Always check the faucet for the current limit. If your request exceeds the limit, the faucet will notify you.

In approximately one to two minutes, you should receive the requested amount of CAM in your Camino Wallet. Verify this in your Camino Wallet interface.

Once the funds are received in your Camino Wallet, they will be on the X-Chain and you will need to transfer them to the C-Chain in order to use them for smart contract deployment.
