In a new class action lawsuit, Silvergate Financial institutions and CEO Lehner Lane were found to have "aided and abetted" Rob Bankman-Fried (Sam Bankman-Fry,SBF) and two physical lines, FTX and Alameda Research, to plan multibillion-dollar fraud schemes.

The proposed class action action was filed in the United States District Court for the Western District of Florida on Feb. 14, through a defense lawyer for a FTX client in San Francisco. When FTX went bankrupt last year, the customer's data encryption account was frozen by about $20, 000.

Appellant Soham Bhatia alleges that Silvergate Bank, its head office Silvergate Capital Corporation and CEOAlan Lane knew about the customer assets of FTX, the Alameda Research application, and accused them of withholding "the actual characteristics of FTX" from customers.

"at most relevant times, Silvergate, Bankman-Fry and Lane were all in collusion with each other," the prosecution said.

The complaint alleges that Silvergate and Lane assisted, abetted, encouraged and fully assisted Bankman-Fry to cooperate in the implementation of deceptive programmes against the appellant and the class.

On the basis of aiding, abetting, motivating and many illegal acts, omissions and other erroneous acts of aiding the above allegations, the defendant is aware of his erroneous practices and is aware that the child's actions will to some extent assist him in carrying out his illegal design.

The lawsuit provides for compensation for losses, restoration of normality and return of profits, the amount of which will be specified in the trial.

However, this prosecution still needs the authentication of the regional court, which is also an important process before the class action is carried out.

The new lawsuit comes just two months after another class action against Yinmen.

On December 14, appellant Joewy Gonzalez filed a similar class action in the District District Court of Southern California, alleging that Silvergate played a role in "further promoting FTX's investment fraud" by aiding and abetting a data encryption trading center when depositing FTX customers' savings into Alameda's bank account.

On January 10, the Southern California District Court of the United States filed a class action against Yinmen Capital, alleging that the sources of Yinmen assets could not be found to involve money launderers in South America, with the amount of money laundered exceeding US $425 million.

Other companies have been accused of similar wrongdoing.

Last week, February 6th, algorithmic trading firm STATISTICA Capital filed a possible class action lawsuit against Signature Bank, which is based in New York, claiming that it "specifically understands and facilitates today's notorious FTX fraud."

"in particular, Signature understands and allows FTX customer assets to be mixed in proprietary, distributed book settlement Internet Signet," it wrote.

Cointelegraph had already contacted Silvergate for comment, but did not receive a text message when it was released.
