Rating agency Bluechip upgraded Tether’s corporate grade to C from D after a KPMG audit concluded the issuer’s reserves exceeded its liabilities by $6.8 billion as of December 31, 2025. Separately, blockchain security firm Hacken reported that about $91.3 billion of USDT on Tron is controlled by a multisig where any two keys can change contract settings, including minting tokens and freezing addresses. Hacken warned reused keys on Ethereum, Avalanche and Celo extend this governance risk, giving USDT a cybersecurity score of 3.3 out of 10, while USDT continues to underpin crypto liquidity with a market value near $183.5 billion.
This update represents a notable development in the Crypto sector. Organizations and founders tracking this space should evaluate potential strategic and technical implications on their operations.
