N3XT, the blockchain-powered narrow bank built for instant, programmable payments, says it is redefining the B2B payments industry by expanding access to the N3XT Digital Dollar (NDD) — described as the first institutional-grade deposit token for businesses available beyond the bank's own client base.

Business payments today operate under a binary, according to the company: every dollar must be either stuck in tokenized deposits trapped within bank walls, or held in a stablecoin that lacks the protections of a traditional bank. The moment a business sends capital beyond those walls, transactions revert to legacy rails with costly, multi-day wire delays. NDD is designed to break down these walled gardens, giving businesses the power to make payments to non-custodial blockchain addresses globally and around the clock, using a bank-regulated U.S. dollar deposit token.

That binary mirrors today's market. Bank-issued tokenized deposits, such as JPMorgan's JPM Coin — rebranded Kinexys in late 2024 — have largely operated as closed-loop instruments usable only among the issuing bank's own clients, while widely circulating stablecoins like USDC and USDT run on public blockchains but are not bank deposits. The U.S. regulatory line between the two models sharpened in 2025, when the GENIUS Act created a federal framework for payment stablecoins while excluding bank-issued deposit tokens from its definition, leaving them under existing bank supervision.

"Traditional banking forces businesses to mold their financial operations to rigid settlement schedules and multi-day clearing delays," said N3XT Founder and CEO Jeffrey Wallis. "N3XT is breaking this mold. We're moving past closed-loop tokenized deposits by enabling usability beyond our clients. By bringing real-time, on-chain dollar liquidity directly to businesses, we're providing them with true accessibility and autonomy over their capital."

NDD is backed 1-to-1 by cash or very short U.S. Treasuries, with reserves matched to tokens, thereby ensuring a constant 1-to-1 backing. N3XT also maintains regulatory capital. That reserve posture tracks the narrow-bank concept the company invokes — a model traditionally defined by holding deposits in cash and short-term government securities rather than extending credit.

"Our mission at N3XT is to enable the transfer of actual U.S. Dollars with the speed of crypto," said N3XT Founder Scott Shay. "This is what banking should look like in the 21st century. Businesses everywhere should be able to make immediate, secure transactions without having to choose between flexibility and peace of mind. With NDD, they now get the best of both worlds."

According to N3XT, businesses will use NDD to send funds to blockchain addresses outside the bank, automate multi-party payment logic, manage liquidity between blockchain addresses, and dramatically reduce the cost of cross-border payments compared with legacy rails. The company lists four principal benefits:

• 24/7/365 Settlement – NDD eliminates legacy multi-day clearing delays and time-zone restrictions by executing cross-border B2B settlements within seconds, operating continuously 24/7/365 with zero bank fees.
• Proactive Compliance & Bank-Grade Safety – Rather than relying on a reactive denylist, NDD pre-screens blockchain addresses to create an allowlist, mitigating the chances of bad actors gaining access to NDD.
• Smart Contract Programmability – As an ERC-20 token, NDD enables holders to use programmable workflows on Ethereum, such as atomic swaps, which can help reduce proof-of-funds friction or compress multi-party payment waterfalls from weeks to minutes.
• User Accessibility – NDD will allow non-bank customers to securely hold and transact without opening a N3XT bank account. This will first be available to enterprises with N3XT client-nominated blockchain addresses, then open to any business that nominates a non-custodial blockchain address for allowlisting.

"Regulatory compliance is at the forefront of everything we build, ensuring enterprise treasurers have 100% certainty that their funds are backed 1-to-1 by real liquid dollars," said N3XT Founder and CTO Aurélien Bonnel. "By creating a core banking system on-chain, we empower organizations to execute instant transactions safely with real-time balance tracking — delivering a level of speed, security, and visibility no traditional bank can match."

How far the model travels will depend on whether businesses beyond N3XT's client base adopt allowlisted non-custodial addresses at scale — an open question that parallel industry efforts, such as the Bank for International Settlements' Project Agorá experiment testing tokenized correspondent banking with central banks and dozens of commercial banks, are also probing.

"We are actualizing a corollary to Satoshi Nakamoto's vision by moving U.S. Dollars directly on-chain," said Shay. "NDD is just the beginning, and we're already looking ahead to what's next as we continue to redefine B2B payments."
