Four DVNs only helps if they're run by independent teams — KelpDAO's $292M drain hit because one compromised verifier had OFT mint authority on 116,500 rsETH. Tighter rate limits are the structural fix; the attacker cleared the vault in hours because nothing capped per-epoch outflows. If Ether.fi's new caps force multi-day exfiltration, a total-loss scenario becomes pause-and-recover.
