KilChain had 148 million drained, and Cosmos Labs only told validators to halt operations? Isn’t this response way too passive? Are users’ assets actually safe?

From one TAC account being drained to MANTRA’s 30-hour outage, the entire Cosmos ecosystem’s emergency response has been noticeably slow. What’s most unsettling is that officials are being evasive even about the affected chains and vulnerability details, leaving users helplessly anxious. All EVM chains should conduct self-checks immediately—don’t wait until hackers have torn down the entire door to remember to lock it.

With such a major vulnerability, are they not disclosing the details and waiting for another chain to suffer?
