Ethereum is powering Wall Street's future. The crypto scene at Cannes shows how far it's come

CANNES — Wall Street's new plumbing is being built on Ethereum and this week its architects took over the same French Riviera villas and red carpet venues that host the Cannes Film Festival in May.

The Ethereum Community Conference, or EthCC, took over the beachside town that was swarming with crypto founders, developers, and some of the institutional giants now building atop the infrastructure.

The crypto elite climbed the iconic red-carpeted steps of the Palais des Festivals — a cinematic landmark now repurposed as the stage for Ethereum's flagship European event.

"The atmosphere this year was palpable in Cannes," said Bettina Boon Falleur, the powerhouse behind EthCC for the past seven years. "The prestige of the location, combined with the quality of talks, has reinforced Ethereum's stature and purpose in the wider ecosystem."

Private parties sprawled across cliffside estates and exclusive resorts, but the conversations were less about price action and more about the blockchain's evolving role as the back-end of global finance.

EthCC, now in its eighth year, has tracked Ethereum's trajectory from scrappy experiment to institutional backbone.

"That impact was unmistakable this year," Falleur said. "From Robinhood embracing decentralized finance infrastructure via Arbitrum to local governments like the City of Cannes exploring deeper integration with the crypto economy."

Indeed, one of the boldest moves came this week from Robinhood, which became the first publicly traded U.S. company to launch tokenized stocks on-chain.

At a product showcase held inside a Belle Époque mansion overlooking the sea, Robinhood unveiled a sweeping new crypto strategy — including the ability for European users to trade tokenized U.S. stocks and ETFs via Arbitrum, a Layer 2 network built on Ethereum.

The announcement helped push Robinhood stock past $100 for the first time, capping off a week of fresh all-time highs and a more than 30% rally since being snubbed by the S&P 500 during a recent rebalance.

Ether, the token native to the Ethereum blockchain, was up nearly 6% on the week and several public equities tied to the blockchain have rallied alongside it.

BitMine Immersion Technologies, a company that mines bitcoin, gained more than 1,200% since announcing it would make ether its primary treasury reserve asset. Bit Digital, which recently exited bitcoin mining to "become a pure play" ethereum staking and treasury company, gained more than 34% this week. And SharpLink Gaming, which added more than $20 million in ether to its balance sheet this week, jumped more than 28% on Thursday.

Ether ETF inflows are rising again too — a sign that institutional investors are warming back up.

Ether is still down more than 20% this year and lags far behind bitcoin in market cap and adoption. But funds tracking ETH have seen two straight months of mostly net inflows, according to CoinGlass data. Still, ether ETFs total just $11 billion — compared to $138 billion in bitcoin ETFs.

Institutions aren't betting on Ethereum for hype — they're betting on infrastructure.

Even as prices stall and the network faces headwinds from slower base layer revenues and faster rivals like Solana, the momentum is shifting toward utility.

"Ethereum is getting plugged into these core transactional systems," Paul Brody, global blockchain leader at EY, told CNBC on the sidelines of EthCC. "Investors, savers, people moving money — they are going to start shifting from some of the older mechanisms of doing this into Ethereum ecosystems that can do these transactions faster, cheaper, but also very importantly, with significant new functionality attached to it."

Deutsche Bank recently announced it's building a tokenization platform on zkSync — a faster, cheaper blockchain built on top of Ethereum — to help asset managers issue and manage tokenized funds, stablecoins, and other real-world assets while meeting regulatory and data protection requirements.

Coinbase and Kraken are also racing to own the crossover between traditional stocks and crypto.

Coinbase has filed with the SEC to offer trading in tokenized public equities, a move that would diversify its revenue stream and bring it into more direct competition with brokerages like Robinhood and eToro.

Kraken announced plans to offer 24/7 trading of U.S. stock tokens in select overseas markets.

BlackRock's tokenized money market fund, BUIDL — launched on Ethereum last year — offers qualified investors on-chain access to yield with redemptions settled in USDC in real time.

Stablecoins, meanwhile, continue to serve as the backbone of Ethereum's financial layer.

Circle's USDC — the second-largest stablecoin — still settles around 65% of its volume on Ethereum's rails. According to CoinGecko's latest "State of Stablecoins" report, Ethereum accounts for nearly 50% of stablecoin market share.

"The builders and contributors at EthCC aren't chasing the next bull run," Falleur said, "they're laying the groundwork to make Ethereum home for the next billion users."

Even as newer blockchains tout faster speeds and lower fees, Ethereum is proving its staying power as a trusted network.

Vitalik Buterin, Ethereum's co-founder, told CNBC in Cannes that there is an assumption that institutions only care about scale and speed — but in practice, it's the opposite.

"A lot of institutions basically tell us to our faces that they value Ethereum because it's stable and dependable, because it doesn't go down," he said.

Buterin added that firms often ask about privacy and other long-term features — the kinds of concerns that institutions, he said, "really value."

Tomasz Stańczak, the new co-executive director of the Ethereum Foundation, said institutions are choosing Ethereum for the same core reasons.

"Ten years without stopping for a moment. Ten years of upgrades, with a huge dedication to security and censorship resistance," he said.

He added that when institutions send orders to the market, they want to be "absolutely sure that their order is treated fairly, that nobody has preference, that the transaction actually is executed at the time when it's delivered."

Those guarantees have become increasingly valuable as stablecoins and tokenized assets move into the mainstream.

The Senate's recent passage of the GENIUS Act, along with Circle's IPO, gave the industry a regulatory tailwind and helped reinforce Ethereum's role as the infrastructure layer for tokenized finance.

Ethereum's core values — neutrality, security, and censorship resistance — are emerging as competitive advantages.

The real test now is whether Ethereum can scale without losing its values.

"We don't just want to succeed," Buterin said from the mainstage of the Palais this week. "We want to be something that is worthy of succeeding."

He said the hope is that future generations will look back and see a network that truly delivered openness, freedom, and permissionless access to the masses.

But the week didn't end in the conference halls, it closed with tradition. On the balcony of Villa Montana, overlooking the Bay of Cannes, the rAAVE party lit up.

White-clad guests sipped cocktails as the DJ spun by the pool, haze curling from smoke machines.

This year, Chainlink co-founder Sergey Nazarov and DeFi icon Stani Kulechov, founder of Aave, stood atop the balcony overlooking the crowd and the light-dotted skyline of Cannes.

It was a fitting snapshot of the momentum behind Ethereum's institutional rise and symbolic of Web3's shift from niche experiment to financial mainstay.
