Cosmos Hub Proposal for ATOM Refund Crushed by 94.64% Veto Vote
On September 22, 2026, an attacker exploited governance vulnerabilities in the Neutron protocol, gaining control over contracts worth approximately $9.4 million.
The attack allowed the attacker to spend around $20,199 to purchase 31.6 million NTRN tokens and gain controlling rights over 10 to 11 protocol contracts.
Validators responded by halting the Cosmos Hub at block height 33,086,740 for roughly 25 hours, keeping the network offline until September 23.
A proposal titled 'ATOM Refund & Justice Bounty' sought to return 1.2 million ATOM to the attacker's wallet and proposed a 500,000 ATOM bounty for voters who supported it.
The proposal faced a staggering 94.64% 'NoWithVeto' vote, with 63.4 million ATOM worth of voting power casting 'NoWithVeto' ballots. The remaining 5.36% of votes were split between abstentions, standard 'No' votes, and one 'Yes' vote.
