Getting Started

The Milkomeda C1 sidechain uses MilkADA as its base asset for paying fees and gas. To access the sidechain, you will need a Cardano wallet with some ADA as well as the MetaMask browser extension.

On the following pages we will walk through the steps to create a Cardano wallet in Flint, configure MetaMask to get a Milkomeda C1 address, and finally send ADA to be converted into MilkADA on Milkomeda C1.

Our first step is to install Flint Wallet. Proceed to the next section to begin.

Getting a Cardano Wallet (Flint)

Flint Wallet is a Chrome extension that serves as a convenient go-to light wallet for DeFi and NFTs. The current version of Flint allows users to enable "Milkomeda mode" to send transactions to the Milkomeda C1 sidechain. Install Flint Wallet by visiting the following link while using Chrome browser and clicking the “Add to Chrome” button: Install Flint Wallet

After installing, click the "puzzle piece" icon     at the top right of the Chrome window to access your extensions. Select Flint. Within the Flint Wallet window, proceed past the initial warning screen, click “Let’s Begin”, choose your language, click “I agree”, and when you arrive at the screen shown below, click the “Mainnet” button.

Next, click “Confirm”, “Create a new wallet”, and write down a copy of your recovery phrase.

Confirm the recovery phrase at the next screen, set a wallet password, and click “Create my wallet”. For now you can select “Skip” at the App Passcode screen, and then click “Finish”. You should now have a Cardano wallet, as shown:

Note that to proceed further you will need to fund your wallet with some ADA. Refer to the "Get Help" section at the end of this document if you require assistance or encounter trouble at this stage.

Next, we will configure MetaMask to connect to the Milkomeda C1 sidechain.

Get and Setup a Milkomeda Wallet (Metamask)

The next step is to obtain an address on the Milkomeda C1 sidechain where we can receive our MilkADA. For now, we recommend using MetaMask for this step.

First, install MetaMask for Chrome. Then, click the Chrome Extensions icon     and select MetaMask. Within the MetaMask window, click "Get Started" and then "Create a Wallet". Set a wallet password and click through the rest of the setup screens. When finished, you should have a new empty wallet as shown below. Select the network dropdown at the top right of the MetaMask screen.

From the dropdown list, select “Add Network” and enter the following:

Network Name: Milkomeda Cardano (C1)

New RPC URL: https://rpc-mainnet-cardano-evm.c1.milkomeda.com;

Chain ID: 2001

Currency Symbol (Optional): MilkADA

Block Explorer URL (Optional): https://explorer-mainnet-cardano-evm.c1.milkomeda.com

Click “Save”, and you should now see "Milkomeda Cardano (C1)" in the network dropdown. Copy your C1 wallet address to the clipboard by clicking on the account name, as shown.

Now we are ready to return to Flint Wallet and send our ADA to be converted to MilkADA.

Moving Assets to Milkomeda C1 (Wrapping)

Open the Flint Wallet window and click "Send". At the next screen, enable the "Milkomeda mode" toggle, paste the Milkomeda C1 wallet address currently in the clipboard into the "Milkomeda Ethereum Address" field, and enter the amount to send (1 ADA in this example). Then click "Continue".

At the confirmation screen, enter your wallet password and click "Send".

The transfer will require 10 confirmations, which should take approximately 5 minutes. Once the transaction is confirmed, the transferred MilkADA should be visible in your C1 wallet in MetaMask.

Moving Assets Back to Cardano (Unwrapping)

To move assets from Milkomeda C1 sidechain back to Cardano, use the Milkomeda Cardano Unwrap Bridge. Follow the steps below to unwrap milkADA and receive ADA in your Cardano mainnet wallet.

First, access the Milkomeda Cardano Unwrap Bridge and connect your MetaMask wallet.

Click "Next"

Connect to the Milkomeda C1 Sidechain

Next, enter the amount of milkADA to unwrap or click the arrow to select a different asset to unwrap, and paste your Cardano wallet address in the "To" field. Then, click the "Next Step" button.

Sign the transaction for unwrapping the assets in MetaMask by clicking "Confirm".

Next, wait for blockchain confirmation.

At this stage, the address bar of your browser will contain some information about the unwrapping transaction. An example is shown in the figure below.

The meaning of each of these elements in the address bar is as follows:

• The EVM unwrapping transaction ID
• The unwrapped token amount
• The name of the token being unwrapped

To look up more detailed information about the unwrapping transaction, go to Milkomeda Blockscout explorer and paste the EVM unwrapping transaction ID into the search box, as shown below.

The unwrapping process is now complete. After waiting for the necessary transaction confirmations, you should see the unwrapped asset in your Cardano Mainnet wallet.
