ADA Slides 6.5% to $0.167 as Hoskinson Reignites Ethereum-EUTXO Feud

ADA fell 6.5% on July 8, slipping back below $0.17 to trade near $0.167 after briefly clearing $0.18 during the recent broader market rally, erasing most of its weekly gains. The drawdown coincided with a public dispute Cardano founder Charles Hoskinson opened against what he called an intentional silence around Cardano’s technology inside Ethereum development circles, according to CaptainAltcoin.

The price action places ADA back inside the range it has struggled to break out of for weeks, with the token unable to sustain moves above the $0.18 handle even as sentiment across majors briefly improved. Traders watching the pair will note the round-trip: a rally toward $0.18, followed by a reset that wiped the week’s advance in a single session.

Hoskinson’s EUTXO claim

Hoskinson posted his critique on X on July 7, framing the omission of Cardano from Ethereum technical discourse as deliberate. “It’s not like I’ve been literally working on this topic for over 10 years of my life and launched a cryptocurrency that was number three on CoinMarketCap with millions of users to deploy it,” he wrote. “It’s literally a crime in the Ethereum inner circles to mention Cardano.”

The dispute was triggered by an Ethereum developer’s thread proposing that payments be treated as one-shot objects rather than permanent state, crediting Bitcoin’s UTXO design and suggesting Ethereum could adapt the same approach for payments. Hoskinson argued that Ethereum developers cannot credit Cardano’s Extended UTXO (EUTXO) model because, in his words, they are “literally trying to copy it.”

He further claimed that proving existence from transaction history while retaining only a spent bit in state could cut permanent state storage by roughly 99.8%, positioning EUTXO as the more scalable architecture for on-chain data retention versus Ethereum’s account-based model.

Account-based vs. UTXO: the structural trade-off

Ethereum’s account model tracks balances as persistent state, which underpins its dominant DeFi liquidity and composability. Cardano’s EUTXO treats payments as discrete, spent-and-destroyed objects extended to support smart contracts, a design proponents say yields more predictable transaction costs, better parallelization and stronger privacy properties, but one critics argue is harder to build complex applications on.

The technical rivalry predates this exchange: Hoskinson co-founded Ethereum before departing to build Cardano, and the two ecosystems have diverged sharply since, with Cardano marketed as the research-driven alternative. Hoskinson’s latest remarks frame renewed Ethereum interest in UTXO-style optimizations as validation of that long-standing technical bet.

What the data shows so far

Despite the technical argument, ADA’s market performance has not tracked Cardano’s architectural claims. The token’s failure to hold above $0.18 and its swift retracement to $0.167 underscores a pattern seen across the cycle: narrative catalysts from Hoskinson generate attention but have not translated into sustained price strength or liquidity inflows for ADA relative to ETH.

Whether Ethereum’s exploration of UTXO-adjacent designs for payments develops into a concrete roadmap item remains unconfirmed, and no Ethereum core developer has publicly credited Cardano’s EUTXO design in response to Hoskinson’s claims.
