In an April 23 Coinage interview, Arbitrum Security Council member Griff Green explained the decision to invoke emergency powers and freeze $72 million in assets linked to North Korean hackers. Green acknowledged that doing nothing carried no personal risk to council members, but argued the existential threat to DeFi as a whole made inaction untenable.
The operation hinged on the funds sitting idle in a Layer 2 address long enough to coordinate with SEAL 911 — ultimately triggering the first-ever 9-of-12 multi-sig emergency execution in Arbitrum's history. The assets were transferred and frozen before they could be moved.
Green addressed concerns about a small group of individuals intervening unilaterally on-chain, arguing that true checks and balances in decentralised systems ultimately rest with the market and token holders — not the council itself.
