Deblock, a French fintech founded in October 2022 by former Revolut and Ledger executives, has introduced a groundbreaking current account offering a 4% annual interest rate with no conditions. This innovative product combines traditional banking with decentralized finance (DeFi), allowing users to earn daily interest without deposit limits, withdrawal fees, or lock-in periods. The account is available via Deblock's iOS and Android apps, regulated by both the ACPR and MiCA (AMF). While the 4% rate is guaranteed only until April 30, 2026, it remains a highly competitive alternative to traditional savings accounts like France's Livret A, which currently yields just 1.5%. This article explores how Deblock achieves this yield, its DeFi mechanics, and what users should consider before signing up.

What Makes Deblock’s 4% Current Account Unique?

Unlike traditional banks or even most neobanks, Deblock’s current account doesn’t impose eligibility criteria, deposit caps, or withdrawal restrictions. Interest is compounded daily and credited directly to the account—no minimum balance or direct deposit requirements. For context, France’s Livret A (a state-regulated savings account) offers a fixed 1.5% rate (tax-free) but is capped at €22,950. Meanwhile, competitors like Revolut or N26 often tie high-yield perks to subscription tiers or spending thresholds. Deblock’s flat 4% rate, though subject to a 31.4% flat tax (since January 2026), still outperforms most alternatives post-tax.

How Does Deblock Achieve a 4% Yield?

The secret lies in DeFi. When users activate the interest feature, their euros are converted into EUR CoinVertible (EURCV), a MiCA-compliant stablecoin issued by SG-Forge (Société Générale’s blockchain arm). These funds are then lent via Morpho, an audited DeFi protocol on Ethereum, which generates yield from decentralized lending markets. Crucially, users retain full custody of their assets—neither Deblock nor third parties can freeze or transfer funds. The 4% rate is variable after April 2026, adjusting to DeFi liquidity conditions. Jean Meyer, Deblock’s CEO, emphasizes their mission: "Your money should work for you daily, without gatekeepers."

Risks and Regulatory Considerations

While Deblock’s banking services are MiCA-regulated, its DeFi component operates under Techblock Ltd, falling outside EU investor protections. This means no FDGDR (France’s deposit guarantee) coverage, similar to crypto products. Users must also navigate volatility risks: though EURCV is 1:1 euro-backed, DeFi protocols like Morpho aren’t immune to smart-contract exploits. As Meyer notes, "We prioritize transparency—this isn’t magic, just tech-driven efficiency."

Step-by-Step: How to Open a Deblock Account

1. Download the app (iOS/Android).
2. Sign up in 2 minutes (French IBAN provided).
3. Activate the "4% Interest" feature in settings.
4. Deposit funds—no minimum required.
5. Earn daily interest, withdraw anytime.

Deblock vs. Traditional Savings: A Quick Comparison

: 1.5% (tax-free), €22,950 cap, state-backed.
: 4% (post-31.4% tax), no cap, DeFi-backed.
: ~3% with conditions (e.g., Premium tiers).

Expert Take: Is It Worth It?

"For tech-savvy users comfortable with DeFi, Deblock’s offer is compelling," says a BTCC analyst. "But conservative savers might prefer the safety of Livret A." The trade-off? Higher yield vs. regulatory uncertainty.

Future Outlook

Post-April 2026, Deblock’s rates will fluctuate with DeFi markets. The fintech plans to expand its crypto-wallet integrations, potentially adding staking options. As Meyer puts it, "This is phase one of redefining banking."
