EthCC Cannes Flash Report: When Bankers Enter the Developers' Conference

By Zhang Ling, Deep Tide TechFlow

From March 30 to April 2, EthCC—the largest annual Ethereum conference in Europe—was held at the Palais des Festivals of the Cannes Film Festival.

More than 400 speakers, a four-day agenda, 15 tracks. But the most worth-noting thing this year is not the content of any single talk, but the composition of the audience has changed.

It’s not new to see Société Générale’s SG-Forge CEO Jean-Marc Stenger, Aave founder Stani Kulechov, and Vitalik Buterin appearing on the same stage. What’s new is that traditional finance names such as Bloomberg, S&P Global, BNP Paribas, Euroclear, Amundi, and Tradeweb are, for the first time, appearing in the Ethereum community conference agenda as official participants.

Ethereum France founder Jérôme de Tychey’s judgment is very direct: “2026 is the year Ethereum and the entire crypto ecosystem become specialized.”

Aave V4: The “institutional upgrade” of DeFi lending

The most heavyweight product release during the conference was Aave V4 going live on the Ethereum mainnet. As the largest lending protocol in DeFi (TVL exceeding $24 billion), this upgrade isn’t just patching up—it’s a structural rebuild.

V4 introduces a “Hub-and-Spoke” model: liquidity is concentrated in a shared Hub, while each independent lending market (Spoke) can have its own collateral rules, risk parameters, and repayment logic, and at the same time access the shared liquidity pool through credit lines governed by governance controls.

The core contradiction this design addresses is: in the past, DeFi lending either put assets of different risk tiers into the same pool (risk contagion), or split them into independently deployed contracts (liquidity fragmentation). V4 allows the two to coexist.

More importantly, V4 has an institutional intent. The new architecture supports institution-specific lending environments, structured credit products, RWA (real-world asset) collateralized borrowing, and fixed-rate products. Kulechov states clearly: “DeFi has already built deep liquidity. V4’s task is to channel that liquidity into real credit markets.”

Initial Spoke partners include Lido, EtherFi, Kelp, Ethena, and Lombard. Supported assets cover USDT, USDC, EURC (Circle’s euro stablecoin), XAUt (Tether’s gold token), cbBTC (Coinbase-wrapped Bitcoin), among others. Chainlink is the exclusive oracle provider.

It’s worth noting that the rollout of V4 was not smooth. In February, Aave’s main engineering team, BGD Labs, announced it was parting ways with the DAO, citing disagreements over the protocol’s direction. Weeks later, Aave’s largest governance delegate, Aave Chan Initiative, also announced its exit. Despite the departure of key contributors, V4 still passed governance votes and was deployed successfully. The AAVE token is currently trading around $98, down approximately 40% over the past 12 months.

The Agora: First institutional-only forum debut

This year’s most significant structural change at EthCC was the debut of “The Agora,” an institution-only forum co-curated by crypto market data firm Kaiko, held on March 31 at the Palais des Festivals of Cannes.

This is EthCC’s first official satellite event, with a clear focus: “An institutional event where digital finance meets open-minded thinking.” Topics covered include tokenization of financial instruments, evolution of crypto market structure, institutional trading infrastructure, and capital efficiency in digital asset markets. About 60 expert speakers addressed roughly 600 participants from traditional finance and Web3.

The lineup of participating institutions highlights the core issue: Bloomberg, S&P Global, BNP Paribas, Euroclear, Amundi, Société Générale-Forge, Tradeweb, Google, and leading blockchain projects. This isn’t a scene of “bankers visiting the crypto world,” but rather “bankers discussing how to migrate their business onto the chain.”

Regulatory puzzle coming together: MiCA + CLARITY

One of the main themes of the conference was the arrival of regulatory clarity.

In Europe, the comprehensive framework of MiCA (Markets in Crypto-Assets Regulation) is expected to be fully implemented by mid-2026, covering exchanges, stablecoins, and institutional participants. Coupled with new crypto tax reporting rules across EU countries, the EU is building a systematic regulatory framework for digital assets.

In the US, the CLARITY bill (full name: Comprehensive Legality and Regulatory Integrity for Technology) continues to advance, providing legal clarity at the intersection of blockchain and traditional finance.

Multiple discussion panels conveyed the same message: regulatory uncertainty was once the biggest barrier to institutional entry, but that obstacle is now being systematically dismantled. The remaining questions are no longer “whether to enter,” but “which chain to choose, which products to use, and at what pace to deploy.”

YAP Global CEO Otto Jacobsson summarized the atmosphere most accurately: “Developers, founders, and institutions are now sitting in the same room discussing DeFi, stablecoins, and on-chain finance. These conversations are happening within the framework of MiCA and Europe’s new regulations.”

EthCC peripheral events: Stablecoin summit and hackathon

EthCC’s week isn’t limited to the main conference. Alongside it, Cannes hosted a series of satellite events.

The Stable Summit focused on the stablecoin ecosystem, discussing how stablecoins and tokenized deposits are transforming cross-border payments, settlement systems, and capital markets. The Hack Seasons Conference Cannes brought together blockchain founders and institutional investors. On March 30, Aave hosted a “DeFi Day Cannes” session. After EthCC concluded, ETHGlobal’s hackathon continued the tradition of attracting top developers—around 1,000—last year in Cannes.

The true significance of EthCC isn’t any single release or talk. It marks a turning point: the Ethereum ecosystem’s main narrative has shifted from “what we’re building” to “who is using it, how they’re using it, and within what compliant framework.”
