Tether is facing a $2.4 billion lawsuit from Celsius Network over a 2022 agreement. The dispute stems from Tether's provision of USD₮ to Celsius, backed by Bitcoin collateral. When Celsius failed to post additional collateral in June 2022, they instructed Tether to liquidate the BTC collateral, resulting in an approximately $815 million position being closed out. Celsius is now seeking the return of $2.4 billion worth of BTC from Tether. The company has vowed to defend against the claims, labeling them as baseless and highlighting that the agreement was made before Celsius' bankruptcy.
