France : Deblock raises €30M to become the first 100% blockchain bank

While the French state is still wavering on integrating crypto into its reserves, the private sector is rushing ahead. Startups, investors, and neobanks are crossing the line, carried by the decentralized wave. Some traditional banks watch. Others test, try, pivot. But a French fintech, Deblock, has decided to bet everything on the blockchain model. The tone is set: simplify crypto finance, back it with familiar banking services, and make it accessible to a much wider audience than insiders only.

Crypto and neobank: when France shows the way

Deblock does not want to merely coexist euros and cryptos. It wants to merge them. Founded in April 2024 by former Revolut and Ledger members, this French fintech offers a classic current account (with a French IBAN) combined with a self-custody crypto wallet. Translation? The user retains full control of their digital assets. No intermediary holds them on their behalf.

With more than 300,000 clients and 100,000 monthly active users, Deblock has tripled its revenue in less than a year. The €30 million fundraising announced in November 2025, led by Speedinvest, Commerzbank, and Latitude, aims to finance a European expansion. Goal: to surpass one million users within six months, starting with Germany and Austria from 2026.

Jean Meyer, co-founder, summarizes their vision: 

Users no longer want to choose between their bank and their cryptos: they want both, in the same place, simply. We are going to massively democratize access to the best decentralized financial services, making them as simple to use as an instant transfer.

Decentralized finance: in France, the bet on simplicity

The strength of Deblock lies not only in its hybrid model. It is the user experience that makes the difference. By integrating DeFi protocols like Morpho and Yield.xyz into accessible savings vaults, the startup promises up to 10% annual interest, paid directly in euros to the account. 

Deposits can start from 1 euro, with no ceiling. All this, free for premium subscribers, and with a 50% performance fee for free users.

Deblock did not invent DeFi, but it removed the frictions. Strategy director Claire Balva explains:

We wanted to reduce the complexity of using DeFi for novice users.

A promise realized through a smooth interface, designed for those who have never set foot in a wallet.

Paul Frambot, founder of Morpho Labs, adds: 

Deblock removes all the complexity of DeFi for its users, giving them magical one-click access to the best yields through Morpho.

Digital sovereignty: the crypto counter replaces the old agency

Deblock positions itself at the crossroads: where banks lock down, it liberates. Where traditional finance hunts, it lets breathe. Thanks to its status as an electronic money institution authorized by the Banque de France, coupled with the MiCA license obtained in May 2025, it checks all regulatory boxes in France and Europe.

But the real pivot is self-custody. No more bank safe keeper. The user is the sole master on board. A strong gesture in an era when banking data is monitored, analyzed, monetized.

Deblock does not play on the same field as giants like Revolut or Chime. It creates its own. A field where the experience resembles that of a classic neobank, but where the architecture is based on decentralized bricks. A frictionless finance, but with conviction.

Figures and reference points to remember:

• €30 million raised to support European expansion;
• More than 300,000 clients in a few months of activity;
• 10% potential annual yield via DeFi vaults;
• Only 1 euro needed to start investing;
• Complete regulation: MiCA, PSAN, and Banque de France approved.

The European Central Bank sees the digital euro as a pillar to strengthen the Union economy. Yet, the path proposed by Deblock diverges. Because this initiative relies on the idea of financial autonomy offered by blockchain. Where the ECB dreams of a programmable and centralized euro, Deblock bets on a fluid, decentralized finance, directly connected with the aspirations of connected citizens. Two visions of the same future, with radically different promises.
