Prime Trust halted deposits, withdrawals after order from Nevada regulator

Stably, which said it relies on Prime Trust as its regulated custodian, cited a letter to clients it said it received from the company. A copy of the letter was also obtained separately by The Block. 

"During this period, we will suspend certain business expansion activities such as signing new customer contracts," Prime Trust said in the letter to Stably. "Prime Trust is actively engaging the NV FID to determine next steps to remediate any concerns and return to business as usual as soon as possible."

Stably pauses services, too

Stably, meanwhile, said it was forced to pause some services and operations as a result. 

The Nevada Financial Institution Division was not immediately able to respond when contacted by The Block. Prime Trust did not immediately respond to a request for comment. 

BitGo said earlier Thursday that it's terminating the planned acquisition of Prime Trust, just two weeks after it announced plans for the deal.

Other companies respond

TrueUSD, meanwhile, said the TUSD stablecoin was not affected.

Cryptocurrency platform HAYVN also said it was not affected, writing in a statement that it has "zero exposure to Prime Trust and multiple USD rails available."
