Haseeb Qureshi, partner zarządzający w Dragonfly, opublikował analizę zatytułowaną „Rada Bezpieczeństwa Arbitrum zamraża 30 766 ETH hakerowi KelpDAO”, stwierdzając, że tego typu transakcja to ArbitrumUnsignedTxType (EIP-2718 typ 0x65/101), czyli transakcja na poziomie systemowym, której nie można podpisać za pomocą zwykłego EOA i którą może wprowadzić wyłącznie Rada Bezpieczeństwa Arbitrum za pośrednictwem ArbOS.
Operacja ta nie wiązała się z cofnięciem łańcucha ani zmianą historii transakcji; pod względem funkcjonalnym jest to przywrócenie stanu: klucz prywatny atakującego nadal może podpisywać transakcje, ale środki ETH z tego adresu są przekazywane przez sam łańcuch. Operacja ta stanowi również przykład uprawnień Rady Bezpieczeństwa w sytuacjach „katastrofalnych stanów wyjątkowych”, zgodnie z opisem zawartym w dokumentacji Arbitrum dotyczącej stopniowej decentralizacji.
