C6 Bank

Back to case studies

About C6 Bank:

C6 Bank is a full-fledged digital bank servicing individuals and businesses in Brazil. Having launched in 2019, the bank has grown to serve over 20 million customers in just four years, offering a range of products, including multi-currency checking and savings accounts, debit and credit cards, travel and loyalty programs, and investment and lending products.

With its existing legacy platform, C6 Bank was unable to service the increasing customer volume and launch new innovative products to meet evolving customer expectations in a timely fashion.

Project overview:

  • Using Vault Core’s Product Library of smart contracts, C6 can now quickly create and launch a full range of products tailored to their customers’ needs, modifying them at speed
  • The bank’s first launched product on Vault Core is a carbon footprint tool – an innovative offering and the first of its kind in Brazil. It calculates customers’ carbon emissions and allows customers to offset them within the app. Within one month of launch, it has over 6 million customers and has offset more than 900 tons of carbon.
  • Vault Core integrates with the C6 Carbon Calculator and its Compensation Service to record all carbon emissions and offset customer purchases through points or cash


Deployment approach:

  • Coexistence: integrated Vault Core into the existing technology stack and launched new customer propositions with existing customers
