Security firm Hacken found that a coordinated breach of just two signing keys could theoretically grant attackers full control over Tether's $91 billion USDT supply, despite Tether receiving an upgraded Bluechip rating. The report identifies structural gaps in Tether's key management architecture, suggesting that the rating upgrade may not fully capture operational security risk at the infrastructure level.
For Armada's crypto-collateral desk, this is a direct prompt to review counterparty exposure to USDT as margin or collateral, and to validate that Fireblocks' MPC-based key management prevents analogous single-point compromise. Armada's SOC 2 positioning requires demonstrable controls around key custody; this report should be circulated to legal and the custody review committee to confirm no analogous gaps exist in the firm's own or counterparties' infrastructure.
