Culper Research Outlines Key Risks Facing the Ethereum Ecosystem
Investment research firm Culper Research has released a critical report, revealing that it has taken a short position in Ethereum. Coinbureau CEO Nic has common on
According to the company, lower fees directly translate into lower revenue for validators, resulting in lower staking economics. Culper further mentions BitMine and argues that the recent increase in transaction activity and active addresses cited as bullish is due to spam transactions and address poisoning attacks rather than true adoption.
The company also indicated that Vitalik Buterin sold around 19,000 ETH as if he knew what was happening. Although this is a significant amount, representing approximately 8% of Buterin’s total holdings, it does not necessarily indicate an exit or loss of confidence.
At the same time, Nic emphasized that the design of ETH allows for future protocol rule changes via coordinated upgrades or forks if economic issues arise. It won’t be easy, politically or technically, but it is possible. Nic stressed that he wasn’t taking sides. However, when a company publishes a detailed thesis and then spends its money on it, it is worth understanding the mechanisms they are putting forward.
How Gas Limit Expansion Ties to Lower Transaction Fees
A crypto commentator and host of The Office Space, MartyParty, also offered an overview of the question. Culper Research has opened short positions in Ethereum, arguing that the network has entered what is described as a potential “death spiral.” The firm’s thesis is based on on-chain data spanning from January 2025 to FEBRUARY 2026.
One of the main focuses of the report is wallet growth after the Fusaka upgrade, and Culper says that 95% of new wallet creation during this period is related to address dusting or poisoning attacks. The company further claims that dusting-related activities now account for approximately 22.5% of all ETH transactions and more than half of the network’s recent transactions. growth.
Additionally, the company is analyzing the economic effects of increasing gas limits across the network, contributing to an estimated 90% drop in transaction fees and a 40-50% reduction in tips per gas. At the same time, these dynamics could put pressure on the economy of validators by reducing the overall revenues of network activity.
Beyond internal network changes, Solana’s competition has captured growing developer and user activity, and reportRumors regarding Buterin’s ETH dumping have sparked backlash from parts of the ETH community.
