Cardano (ADA) Crash Analysis: Causes of the November Slump
Key Takeaways
- Cardano was split by a governance issue and a faulty AI transaction, not a classic hack.
- Panic selling by large investors led to a 16% ADA price drop; technically, ADA is now oversold.
- Opportunities for recovery include ETF news, technical upgrades, and more DeFi liquidity – risks remain.
Introduction
Cardano lost over 16 percent of its value in a few days in November 2025 – but what exactly happened? An AI-generated delegation transaction split the Cardano network into two parallel blockchains, revealing massive vulnerabilities in the decentralized governance system.
In this in-depth analysis, we explain the technical background of the network crash, why professional investors sold heavily, and what concrete opportunities are now emerging for investors.
The Network Crash: Chain Split via Faulty Transaction
On November 23, 2025, Cardano experienced an unprecedented network outage. A user named Homer J., an ADA staking pool operator, used AI-generated terminal commands to create a delegation transaction.
While this transaction was technically valid at the protocol level, it exploited an old security vulnerability in the Cardano software library. The result was devastating: older node versions (validator computers in the network) rejected the transaction, while newer versions processed it.
This led to the network splitting into two parallel blockchains – a "poisoned" chain and a "healthy" one. Block producers began working on separate branches, creating inconsistent data.
Major exchanges like Binance immediately halted deposits and withdrawals as a protective measure to safeguard their users. Analysts on CoinDesk reported on the incident within minutes, leading to massive panic selling.
Who was Homer J. and what were his motives?
Homer J. later stated that he did not act maliciously, but only wanted to replicate the faulty transaction to test network vulnerabilities. He used AI-generated commands to block external traffic sources while conducting his experiments.
Only when block explorers went offline and pool rewards stopped did he realize the full extent of the disruption.
"I am ashamed of my carelessness," wrote Homer J. on social media. "I had no bad intentions, but I put the entire network at risk."

Charles Hoskinson, co-founder of Cardano, however, described the event as a "targeted attack" and suggested potential criminal intent behind it. The FBI was subsequently involved, and the debate within the community over whether it was negligent behavior or a targeted attack continues to divide the community to this day.
The Technical Causes: Governance Failure in a Decentralized System
The incident reveals a fundamental problem with Cardano: decentralized network updates are slow, error-prone, and poorly coordinated. When newer software versions are incompatible with older ones without a strictly coordinated upgrade, exactly these kinds of chain splits occur.
Cardano is based on the Ouroboros Proof-of-Stake consensus mechanism, a theoretically very robust protocol. However, the governance structures – who can change code, how quickly patches can be rolled out, and how the community is involved – were not sufficiently tested for critical scenarios.
The Intersect governance group, Cardano's technical steering body, took several hours to develop a fix and communicate it to all pool operators. For established blockchains like Bitcoin or Ethereum, such a problem could have been escalated and resolved faster because the processes and communication channels are already proven.
Cardano reveals an uncomfortable truth here: decentralization comes with significant coordination costs.
The Price Crash: 16 Percent in Less Than 24 Hours
The ADA price reacted violently and immediately to the network instability. From 0.52 USD, ADA fell to 0.42 USD – a decline of over 16 percent in less than a day.
According to Yahoo Finance, three factors drove the crash:
- Fear of technical failure: Traders and institutional investors feared that the network might not be recoverable or that further critical security vulnerabilities existed.
- Large sales by whales: On-chain analyses show that large investors sold about 50 million ADA, triggering chain liquidations in futures markets.
- Macroeconomic factors: The entire crypto market suffered from weak sentiment and macroeconomic uncertainty; altcoins like ADA lost disproportionately.
The 24-hour trading volume jumped to 1.7 billion USD, while open interest in futures markets fell from 1.95 billion USD to just 641 million USD. Technical indicators showed massively oversold conditions: the Relative Strength Index (RSI) was at 32.5 – significantly below the 30 mark, which indicates extreme oversold status.
Consequences: Liquidity Crisis in the DeFi Ecosystem
A particularly shocking detail came to light days later: a large decentralized finance trader attempted to swap 10 million ADA for the USDA stablecoin. Due to the extremely low liquidity in the automated liquidity pool, the slippage (price slide during the transaction) exploded, and the trader lost over 6 million dollars.
This event shows a critical problem: Cardano's DeFi ecosystem is underdeveloped and fragile. With only 233 million dollars in Total Value Locked – compared to over 60 billion USD for Ethereum – Cardano is still a dwarf in the DeFi space.
Stablecoin presence in the network is particularly critical: only 38 million dollars in stablecoins in a global industry with over 300 billion dollars in volume. This severely limits organic growth and does not attract risk-averse institutional investors.
According to the Cardano Foundation, new partnerships with established DeFi protocols are under negotiation to close this liquidity gap.

What Happens Now? Current Roadmap and Recovery Strategy
The Cardano team acted quickly and decisively: Hotfix 1.1.5 was developed within 6 hours, and pool operators were instructed to upgrade to the new node version. After approximately 6 hours, the network was fully unified again, and all nodes were running on a single chain.
Charles Hoskinson announced several concrete measures:
- Stronger governance processes: Faster voting on critical bugs; Intersect will be equipped with additional resources to make decisions in minutes instead of hours.
- Automated monitoring systems: Detection of anomalous transactions before deployment to the mainnet; machine learning tools for early detection of protocol incompatibilities.
- Accelerated upgrades: The Ouroboros Phalanx upgrade and Leios scaling solutions are to be implemented faster.
Technical Analysis: Opportunities for a Counter-Movement
From a chart technical perspective, ADA is in an interesting setup: the RSI is at an extreme 32.5 – this suggests a counter-movement, as such extremes usually lead to rebounds. Technical support is at 0.48 USD; should ADA hold this mark, a rebound to 0.60 USD or even 0.70 USD could follow.
According to CoinMarketCap analysts, the next resistance level is at 0.58 USD (previous support level). A break above 0.60 USD would signal a bullish trend for the coming weeks.

Medium-Term Catalysts for Price Stabilization
Three concrete events could stabilize and boost the Cardano price in the coming months:
- SEC approval for a Cardano ETF: If the US Securities and Exchange Commission (SEC) approves a Cardano ETF, this could lead to massive institutional inflows and generate stabilizing buying pressure – similar to Ethereum after its ETF approval in 2024.
- Successful technical upgrades and governance reforms: If Cardano proves that it can react faster, more coordinately, and more robustly to critical problems, this would regain the community's trust.
- Recovery and growth of the DeFi ecosystem: New partnerships with established stablecoin providers, improved liquidity, and new smart contract platforms could increase the DeFi TVL from the current 233 million to over 5 billion dollars.
Experts on CoinDesk expect price ranges between 0.36–0.70 USD for the remaining months of 2025.
Conclusion: Cardano at a Turning Point
The November crash was not just a market slump – it was a fundamental failure of governance and the decentralized update process. Cardano must now prove that it can react faster, more coordinately, and more robustly to critical problems.
The good news: no user funds were lost in the crash, the network was quickly restored, and the community mobilized promptly. The central question remains: will Cardano learn from this incident and build a better, more secure network – or will the trust be irreparably damaged?
For speculatively oriented investors with a higher risk tolerance, ADA currently offers attractive technical entry points with chances for 30–50% profit if the catalysts take hold. Conservative investors, however, should wait for concrete governance improvements and ETF news before investing again.
