Announcing Deblock

Most traditional banks still treat crypto as an afterthought. Deblock took the opposite path. From the start, it was built on the belief that financial systems are converging and that people should be able to manage fiat and crypto in one place, with the same standards of speed, security, and compliance.

Deblock holds an Electronic Money Institution (EMI) license and was the first financial institution in France to obtain a MiCA license. Launched in 2024, Deblock combines the ease of a modern neobank with the power of a crypto wallet. Users can move money instantly, switch between euros and digital assets, and manage both seamlessly and with full control.

Redesigning bank accounts atop blockchains

Most banking infrastructure still runs on legacy systems built on traditional databases, where data can be changed at will. Each institution keeps its own private database, which means there is no natural synchronization or interoperability between balances. As a result, transfers are not always instant, cross-border payments remain slow and expensive, and crypto access (when offered) is often limited, locked behind custodial platforms with little flexibility.

The founders of Deblock—Aaron Beck (former Head of Payments at Revolut), Adriana Restrepo (former COO at Revolut), Jean Meyer (former Head of Crypto at Revolut), and Mario Eguiluz (former Head of Engineering at Ledger)—came together to rethink how a bank account should work. They built a new model that combines fiat and crypto, self-custody, and regulatory clarity in one app. Their belief is simple: the future of finance isn’t about choosing between crypto and traditional banking, but about connecting both.

Deblock users can hold and move both fiat and crypto from the same interface. The wallet is self-custodial, meaning users keep control of their keys, but the experience feels as seamless as using a neobank. Payments, conversions, and transfers happen in real time, without unnecessary steps or compromises. Deblock bridges traditional payment rails and blockchains by integrating on/off ramps, swaps, transaction management, and secure key handling directly into the app. It also supports instant payments, automated compliance, and cross-border transfers without hidden FX fees.

Earlier this year, Deblock launched savings vaults called “coffres”, offering up to 6% annual yield in euros. Users simply deposit euros, which are converted into stablecoins and deployed onchain through marketplaces like Morpho and Yield.xyz. The yield is collected and streamed back into their Deblock account in euros.

The product was designed for everyday users: there is no staking to manage, no bridging of funds, and no need to interact with decentralized protocols.The focus is on what matters: offering higher returns, full transparency, and no lock-ins.

The app is now live across France, French overseas territories, and all eurozone countries, with a particular focus on newly launched markets like Spain and Germany. It has already surpassed 200,000 downloads.

Why Deblock chose Dfns to build their wallets

Deblock needed infrastructure that could keep up with its ambitions: enterprise-grade compliance, and the flexibility to scale across assets and jurisdictions. 

• Wallet infrastructure for internal operations: Deblock also uses Dfns to manage its corporate wallets for treasury and business operations. These wallets use Multi-Party Computation (MPC) for security, with detailed identity and access management (IAM) policies. They are designed for full auditability, event monitoring, and strict control of every action.
• Transaction APIs for automation and scale: Dfns’ APIs manage all internal transfers, covering wallet creation, execution, and tracking across 100+ blockchains. Real-time balance data, metadata, and transaction logs allow Deblock’s team to monitor and reconcile activity with ease.
• Enterprise-grade security for finance teams: From onchain fee sponsorship and transaction batching to webhook orchestration and token-level indexing, Dfns supports every step of the transaction lifecycle. Whether topping up vaults or handling peer-to-peer settlements, execution remains secure and seamless.
• Compliance built into the wallet lifecycle: Deblock relies on features like address whitelisting for counterparty management and exportable transaction logs for financial reporting. All operations follow role-based access controls, programmable policies, and verifiable transaction flows.

With Dfns, Deblock automates and secures its crypto operations while maintaining full visibility, governance, and compliance. Deblock is building the future of retail banking where crypto isn’t bolted on, but built in. With Dfns as its infrastructure partner, Deblock can move fast, stay sovereign, and meet Europe’s highest regulatory standards. Most recently, they became the first MiCA licensed financial institution from France. Together, we’re proving that programmable finance can be safe, simple, and accessible.
