Introduce an eth address if your order includes a Dappnode Home with incentives. If you have already placed an order that includes a Dappnode Home with incentives, you will need to include a new address in this order.
If you have purchased a Dappnode Home x Lido you can provide an Ethereum address that will be proposed to be included to the Early Adoption list for CSM mainnet, that also comes with the benefit of a reduced required amount of collateral for the first validator registered with this address registered.
You need to validate your EU VAT number on your profile account before the purchase or it won't be validated and you won't get the VAT exemption.
