European Fintech Blackcat Launches Multi-Wallet App Combining Euro and Crypto Accounts, Completing Rebrand

Blackcat, the European fintech platform formerly known as Blackcatcard, today launched a completely rebuilt mobile app based on a multi-wallet architecture that combines euro accounts and crypto services in a single interface. The launch accompanies a formal rebrand that retires the Blackcatcard name — a change driven by how users had already begun referring to the product.

The new app allows users to create and manage multiple independent wallets — in euros or in supported cryptocurrencies — organised by purpose, use case, or asset type. Each wallet functions as a self-contained financial account within a single ecosystem, supported by a personal EUR IBAN with SEPA transfers, credit-grade cards or integrated crypto buy, sell, and transfer functionality. 

The rebuild comes as European fintech moves beyond single-product offerings. According to AppsFlyer’s 2025 analysis of 187 finance apps across the UK, France, and Germany, the European financial app landscape has become increasingly fragmented, with traditional providers, neobanks, and international platforms each competing in siloed categories. Blackcat’s multi-wallet model is designed to consolidate these fragmented workflows into a single platform.

Regulated infrastructure

Blackcat’s fiat infrastructure is built on Papaya Ltd, a Malta-based Electronic Money Institution authorised and regulated by the Malta Financial Services Authority and a direct participant in the SEPA payment network. Crypto services are delivered through a separately licensed European partner, integrated through an open-banking technology, maintaining a clear separation between fiat and digital asset operations.

This direct SEPA participation means Blackcat processes euro transfers through its own infrastructure rather than routing them through intermediary institutions — a distinction that affects both speed and cost for end users, and one that relatively few EMI-based fintechs in Europe can claim.

Why multi-wallet matters

The multi-wallet model represents a departure from the account-plus-features approach. Rather than a single balance with spending categories or virtual pots layered on top, Blackcat’s wallets are architecturally independent — each with its own balance, transaction history, and potential integrations.

“The wallet-based architecture is a fundamental rethinking of how a financial app should be structured,” said Olegs Cernisevs, PhD, Chief Technology Officer at Blackcat. “Most fintech apps were built as digital copies of a single account. We built something closer to a personal financial operating system — where each wallet is a programmable unit that can eventually connect to different services, partners, and rails.”

What comes next

The wallet architecture is designed as a foundation for future functionality. Planned expansions include partner integrations, open-banking connectivity, and additional asset types — all embedded as native extensions of individual wallets rather than bolted-on features.
