Joseph Seibert, who was head of digital assets at Signature Bank, and four members of his Signet team have joined Fortress Trust, a Nevada-based chartered trust company that specializes in cryptocurrency and Web3. Signature Bank, which was a crypto-friendly institution, was shut down in March after depositors withdrew large sums of money following the collapse of Silicon Valley Bank, another bank with crypto ties. Signet was a payments platform that was popular with Signature’s institutional crypto customers.
