How Cardtonic Uses Breet to Power Stablecoin Deposits for Virtual Dollar Cards
Cardtonic partnered with Breet to bring USDT and USDC top-ups to its platform, creating a frictionless way for customers to fund virtual dollar cards.
The Problem
Cardtonic is a platform where users can get virtual dollar cards. For a long time, the only way to fund such virtual cards was through local bank transfers (Naira or Cedis). Someone in the diaspora holding stablecoins had to convert to fiat first, wait, deal with exchange rate friction, and then fund their card. It created friction the product had no answer to. Customers kept asking: 'Why can't I just use my stablecoins?' The team reached out after speaking to a couple of other API providers and settled with Breet because in their words: 'Breet was the right fit because the responses were fast, the API documentation was clean, there was an instant sandbox environment and the fees were flat.'
What Cardtonic Built
They integrated Breet's API to enable stablecoin top-ups - USDT and USDC directly. Their users can now send stablecoins and have their virtual dollar card funded immediately. No need for conversion, no waiting, and no exchange rate friction at the point of funding. The engineer went straight to the API documentation on day one, and the integration was complete in just two days. In his words 'The sandbox environment reflected how production actually behaves, and technical questions were responded to swiftly'.
Integration Time
2 days from sandbox access to production including one day the engineer describes as 'mostly just being thorough'.

“Breet actually wants startups in the ecosystem to succeed. You can tell the difference between a company that says that and a company that means it. From how quickly they responded to our requests to how flexible their fee is, it was evident that we made the right decision choosing them as our API partner”
