Crypto exchange Kraken is pulling back from using crypto-focused bank Signature Bank for some significant financial transactions, according to a report from Bloomberg, in the latest move away from a specific bank by a crypto exchange.

Non-corporate clients of Kraken will no longer be able to make dollar deposits or withdrawals using Signature, according to an email seen by Bloomberg that was sent to customers on Wednesday. Deposits will be phased out on March 15, while withdrawals will end on March 30.

In its email to users, Kraken said the move was made due to changes by Signature, according to Bloomberg.
