Deblock

Deblock started from the idea that a current account and a crypto wallet should sit in the same app, so customers move between euros and crypto without a separate exchange. The team brought experience from Revolut and from the hardware wallet maker Ledger into the design of the account and the wallet.

In November 2024 Deblock raised 16 million euros and became the second crypto company with the optional PSAN license of the AMF, as Cryptoast reported at the time.

The AMF authorized Deblock SAS on 23 May 2025 as a crypto-asset service provider under MiCA, the first such authorization from the French regulator. The license covers exchange of crypto assets against euros, exchange against other crypto assets and execution of orders for clients.

Custody is not part of the license, because the customer holds the keys of the wallet. The interim MiCA register of ESMA lists 29 host countries beyond France, so Deblock can passport its CASP license across the EEA.

Deblock separates the two halves of the account and treats euros and crypto assets under different rules. Euro balances are safeguarded under payment rules, and the crypto assets sit in a wallet that only the customer can sign for, so the assets stay with the customer even if Deblock itself runs into trouble.

The company has its systems checked in cybersecurity audits twice a year, a control that applies to the payment account and to the access to the crypto wallet alike.

Many searches for Deblock bank refer to the current account in the app, which comes with an IBAN, instant SEPA transfers and a Visa card in virtual or physical form. Interest on the euro balance is paid daily, and Deblock publishes the current rate on its website.

The crypto wallet in the app is self-custodial, which means the customer controls the keys and Deblock cannot move the assets on its own. Customers deposit crypto from other wallets, send it out and exchange it for euros or other crypto assets.

Customers buy crypto assets with the euros in their current account, and every exchange runs inside the app without a transfer to an outside platform. The fees for exchanges between euros and crypto assets and for transfers to other wallets are set out in the Deblock price list.

Deblock SAS is the French simplified joint-stock company that operates the app and holds the MiCA authorization. Its registered office is in Paris, and the team also works from an office in Lille.

Deblock received the first MiCA license granted by the AMF, more than a year before the French MiCA transitional period ended on 30 June 2026. The license lets the firm serve customers in the other countries of the European Economic Area.
