Cardano Juggles Technical Leap and Security Fallout as Hard Fork and Leios Testnet Collide with Capital Flight
Veröffentlicht: 07.07.2026 um 16:08 Uhr, Redaktion boerse-global.de
Cardano is moving in two directions at once. On the infrastructure side, the network is barrelling toward a major governance upgrade while promising a 60-fold throughput increase. On the ground, a wallet exploit has permanently shut down a key service, capital is draining from DeFi, and price gains are already stalling. The tension between ambition and reality has rarely been sharper.
The most immediate catalyst is the Chang hard fork, which depends on a mandatory node update. IntersectMBO released Cardano Node version 9.0.0 on July 6, 2026, requiring all node operators to upgrade before the hard fork activates so-called bootstrap governance thresholds. That shift would hand more decision-making power to the community. Separately, the Ouroboros Leios upgrade is taking shape: the public testnet "Musashi Dojo" went live on June 23, and founder Charles Hoskinson has claimed the final mainnet version, expected later this year, will deliver a sixty-fold throughput increase. In a recent appearance on The Breakdown podcast with David Gokhshtein, he positioned Leios as Cardano's ticket to matching the XRP Ledger's speed — settlement times of three to five seconds and a capacity of up to 1,500 transactions per second. The benchmark matters: XRP's peak in March 2026 hit around 120 transactions per second with roughly 650 concurrent operations, and Hoskinson insisted Cardano could achieve similar performance without sacrificing its founding principles.
But the same day the node update dropped, EMURGO — the ecosystem's founding entity — delivered a starkly different kind of news. SecondFi, a wallet service, will not resume operations after a security breach discovered on June 22 compromised 374 addresses and roughly 16 million ADA, worth about $2.4 million at the time of the incident. EMURGO has assembled an asset-recovery team and urged users to migrate funds through official tools. Compromised wallets are considered permanently unsafe. The closure erodes trust in a network that is simultaneously asking participants to embrace more decentralized governance.
Should investors sell immediately? Or is it worth buying Cardano?
The user base has not fled en masse: since the price bottom on June 23, 14,783 new non-empty ADA wallets have appeared, and large holders are adding to their stacks. Wallets holding between 10 million and 100 million ADA increased their share of circulating supply from 37.66% on June 25 to 38.13% by July 7 — a clear accumulation pattern. Yet the broader ecosystem shows signs of strain elsewhere. Total value locked in Cardano DeFi applications fell from 566 million ADA on June 30 to 462 million ADA on July 6, according to DeFiLlama. Two prominent projects, TapTools and JPG Store, have shut down. Hoskinson used his podcast appearance to defend the ecosystem's spending, pushing back against content creator Big Pey, who had called the Midnight City project a waste of millions with no user acquisition to show for it. Hoskinson said he had lost all respect for Big Pey as an entrepreneur, arguing the critic failed to understand the development cycle for consumer products.
Price action reflects the mixed signals. ADA is trading at $0.18, still 82.4% below its 52-week high of $1.01 from August 2025. The coin rebounded 26% to 28% from its June 26 low of $0.14, but the rally has already faltered. ADA fell for three consecutive days through July 7, slipping below its 50-day moving average of $0.186, with a single-day loss of 5.8% on the final session. The relative strength index sits at 54.7, neutral territory. Derivatives markets are cautious: the long/short ratio on Coinglass dropped to 0.88 — the lowest since June 30 — and open interest shrank 10% to $460 million on July 6 after $1.42 million in long liquidations cleared the way for short sellers. Technically, Cardano is pinned in a narrow band between support at $0.17 and resistance at $0.19, where the 50-day moving average, the upper Bollinger Band, and a key pivot point converge. The daily chart is neutral, but near-term momentum tilts bearish.
Within the ecosystem, decentralized exchange activity paints a contradictory picture. Minswap, the largest Cardano DEX, saw fee revenue plunge 63% in 24 hours, while SundaeSwap V2 collapsed 96% day-over-day. Look at the weekly lens and the story flips: SundaeSwap surged 266% and Dano Finance skyrocketed 1,300%. Short-term noise and medium-term trends are pulling in opposite directions. The coming months will show whether Hoskinson's throughput promises — and the Chang hard fork's governance overhaul — can convert technical milestones into genuine developer and liquidity inflows, or whether past patterns of upgrade-driven rallies that fizzle before fundamentals catch up will repeat themselves.
