    What we do?


    Aion Bank is a fully regulated European bank and credit institution, combining Vodeno’s cutting-edge, private blockchain-based platform with its ECB banking license, strong balance sheet, and deep regulatory expertise. Our mission is to provide a comprehensive suite of embedded banking solutions, enabling businesses to seamlessly integrate financial services into their offerings.

    As part of the UniCredit Group, Aion Bank and Vodeno will accelerate their digital banking offer in strategic markets and will act as a sandbox for innovation for the wider UniCredit Group. Aion Bank and Vodeno's existing Banking-as-a-Service (BaaS) offering across key European markets, including Germany and Poland, will see the bank embed its services - ranging from account access and deposits to lending, payments and loyalty programs - directly into non-banking digital platforms, facilitating seamless customer experiences.
