The Arbitrum Security Council stepped in to freeze 30,766 ETH, worth about $115 million, after the recent KelpDAO exploit. This action, meant to protect community assets, has sparked renewed debate about how decentralized Layer-2 (L2) ecosystems really are.
The Arbitrum Security Council has taken emergency action to freeze the 30,766 ETH being held in the address on Arbitrum One that is connected to the KelpDAO exploit. The Security Council acted with input from law enforcement as to the exploiter’s identity, and, at all times,…

On April 20, 2026, the council worked with law enforcement and technical experts to move the stolen funds from the exploiter’s address to a frozen wallet. Arbitrum said their careful approach made sure no other parts of the chain or user apps were affected during the recovery.
The recovered funds are now inaccessible to the original exploiter and remain under the control of the intermediary wallet. Arbitrum noted that any further movement of these assets will require a formal governance vote, which is expected to be coordinated with relevant stakeholders and legal authorities.
While many in the Ethereum community praised the swift action, Tron founder Justin Sun used the event to challenge the decentralization claims of L2 networks. Sun quoted the announcement, claiming that the ability to freeze funds proves these networks are not truly decentralized, further asserting that Tron remains the most decentralized blockchain.
Ok. I’m officially announcing: the most decentralized blockchain in the world is Tron. https://t.co/dijxWG5rNc

Security Council powers vs. the decentralization ideal
Arbitrum’s Security Council is designed to act in extreme cases of theft or systemic risk, yet critics argue such powers represent a central point of failure.
Similar governance interventions have occurred during major DeFi hacks, where the need to prevent bad debt or total loss often overrides strict adherence to decentralization. Sun’s commentary has drawn mixed reactions, with some users pointing out Tron’s own governance structure and the influence of a few major validators.
The Arbitrum security fix highlights a conflict in Web3 of needing security features like “safety rails” to prevent theft, but also maintaining the core principles of decentralization and immutability. Similarly, Vitalik Buterin has raised concerns and warns centralized control in Ethereum clients and L2s threatens network security and decentralization.
