Walkthrough

Before we start, here is a short demo video to showcase how we create an account and use a decentralised exchange platform like Uniswap to exchange EUR for GBP without any intermediaries and only using smart contracts.

Create a sandbox account

For the innovators, product builders, and other curious minds we've opened up a Sandbox version of our system. Play around with our money in a safe environment to understand how this fits into your platform.

Make sure you have Metamask or a compatible blockchain wallet ready and the sepolia test network before we start.

  1. Start by signing up.
  2. Connect your wallet in the top right corner of the application.
  3. You should be taken to a Link your address page. Press the Link button. When you link your address, you are essentially proving that you are the real owner of the address. This is ensured by having you sign a message with the private key in your wallet.

You have now created your account and you should be able to switch between different currencies.

Adding tokens to your wallet

Now we want to add the EUR and GBP tokens in your wallet. to be able to send and receive the money directly in the wallet

Note! on the mainnet you simply search for Monerium tokens in the wallet and they appear. But now we add them manually because we are using the sepolia testnet

  1. Select your EUR account.
  2. Press the More (three dots) button and account details should be visible.
  3. If you have a Metamask wallet you should see a Add EUR token to wallet button. Press the button and your wallet should ask you if you want to add the token. For other tokens you can enter the token address manually.
  4. Select your GBP account and add it the same way as you did for EUR.

You should now see both the EURe and GBPe tokens in your wallet with zero balance.

Let's fix that and add some test money from a test bank account to your blockchain address

Monerium IBAN

Customers can create a unique Monerium IBAN in their name that is connected to the SEPA payment network. This allows customers to seamlessly collect and send money between bank accounts and their blockchain address.

Let's create a Monerium IBAN for your EUR account.

  1. Select your EUR account in the sandbox.
  2. Press the green Add money button.
  3. Press the Continue button in the Get a Monerium IBAN panel.

You should now see your very own test Monerium IBAN.

PAY-IN / Collect money from bank account to blockchain

We are now going to simulate sending test euros from a test bank account to your blockchain address.

  1. Select your EUR account in the sandbox.
  2. Press the green Add money button.
  3. Enter €1,000 in in the Simulate a bank transfer panel and press the Add money button.

In about 15 seconds you should see the balance increase by €1,000 in the sandbox application and in your wallet.

PAY-OUT / Send money from blockchain to bank account

We are now going to simulate sending test euros from your blockchain address to a test bank account.

  1. Select your EUR account in the sandbox.
  2. Press the blue Send money button.
  3. Enter €500 in in the amount field.
  4. Enter GR16 0110 1250 0000 0001 2300 695 in the IBAN field, or any other valid IBAN you can think of.
  5. Enter any Company name e.g. Monerium and press the Send button.

In about 15 seconds you should see the balance decrease by €500 in the sandbox application and in your wallet.
