$320 Million Exploit Hits Bitcoin Network Layer Used by Exchanges

Hackers exploited a Bitcoin network layer used by exchanges for approximately $320 million, with the attackers claiming the action was intended to expose vulnerabilities rather than profit. The scale puts this among the largest Bitcoin-adjacent exploits on record, and the involvement of exchange infrastructure raises questions about the security of settlement and custody layers that institutional BTC holders depend on.

For Armada's crypto-collateral desk, BTC is a core accepted collateral asset held via Fireblocks, and any compromise of exchange-facing network layers could affect collateral liquidity or counterparty solvency. The team should immediately confirm that Fireblocks' MPC custody is architecturally isolated from the affected network, review BTC LTV ratios against current market volatility, and ensure margin call triggers are calibrated for stress scenarios of this magnitude.

Suggested action Confirm Fireblocks custody isolation prevents exposure to affected network layer; review BTC collateral LTV buffers and counterparty margin call triggers.
