From Signature Bank to N3XT: Former Executives Launch Blockchain-Powered Bank

By Mini MaNewcomer0 rep· 12/5/2025

Former executives from the defunct Signature Bank have launched N3XT, a new digital bank leveraging blockchain technology. This innovative institution aims to provide instant, programmable U.S. dollar payments for businesses, operating under a Wyoming Special Purpose Depository Institution (SPDI) charter. The venture seeks to fill the void left by Signature Bank's closure, offering a modern approach to financial services.

 

Key Takeaways

  • N3XT is a full-reserve bank, meaning all deposits are backed one-to-one by cash or short-term U.S. Treasuries.

  • The bank utilizes a private blockchain system for instant payment settlements and smart contract automation.

  • It is founded by key figures from Signature Bank, including CEO Jeffrey Wallis and founder Scott Shay.

  • N3XT has secured significant backing from prominent venture capital firms like Paradigm and Winklevoss Capital.

 

A New Era of Banking

N3XT, founded by a team including former Signature Bank CEO Scott Shay and former Director of Digital Asset Strategy Jeffrey Wallis, is designed to offer a 24/7 global economy solution for institutional clients. The bank's architecture allows businesses to automate financial operations, such as supplier payments and collateral adjustments, without the constraints of traditional banking hours.

 

Full-Reserve Model and Blockchain Integration

Operating as a "narrow bank," N3XT distinguishes itself by not lending out deposits. Instead, every dollar is fully backed by reserves, with daily disclosures ensuring transparency. The bank's core functionality relies on a private blockchain system, enabling instant payment settlements and the execution of transactions via smart contracts. This approach aims to provide enhanced control and reliability for businesses.

 

Backed by Industry Leaders

The launch of N3XT has garnered substantial support from the venture capital community. Investors include Paradigm, HACK VC, and Winklevoss Capital, the firm founded by Gemini exchange co-founders Tyler and Cameron Winklevoss. To date, N3XT has raised $72 million across three funding rounds, underscoring strong confidence in its business model.

 

Reimagining Payments

N3XT aims to replicate and enhance the services previously offered by Signature Bank's popular Signet platform. By integrating blockchain innovations, the bank seeks to deliver programmable payments that are both instant and compliant, catering to industries such as cryptocurrency, shipping, logistics, and foreign exchange. The bank reports a strong pipeline of interested clients.
