“In light of recent developments & out of an abundance of caution, Coinbase is no longer accepting or initiating payments to or from Silvergate,” Coinbase said on Twitter. “Coinbase will be facilitating institutional client cash transactions with our other banking partners.”

Galaxy Digital, the crypto financial services firm founded by Michael Novogratz, said it continues to have no material exposure to Silvergate. The company took the action “to ensure client and firm assets are secure as part of our vigorous risk-management process,” its spokesperson said in an email.

Paxos issued a similar statement, and Gemini Trust Co., Crypto.com and Cboe Clear Digital LLC are all suspending transfers with Silvergate as well. Circle Internet Financial Ltd. said it’s “unwinding certain services” with Silvergate.

Bitstamp Ltd. went a step further, warning customers of potential losses if they make fresh deposits via Silvergate. “Bitstamp cannot be responsible for any funds deposited into the Silvergate bank account,” the crypto exchange said in a blog post Thursday. “If you do choose to deposit funds into this account, you do so at your own risk.”

Eoin Treacy's view

Silvergate extended what is an accelerating decline today. It is really not a good sign that other crypto firms are pulling business from the bank. Only three weeks ago institutional investors were lining up to put money into the company. That was based on the assumption its exposure to the demise of FRX was contained. Obviously, that is not the case. A significant stabilizing investment will be required to defray the possibility of bankruptcy.
