Tassat's Project NENYA lets regional banks bid for stablecoin reserves as Citi sees $4T market by 2030, addressing concentration risk. Pilot H1 2026.
Tassat, the fintech firm that built Signature Bank's Signet network, unveiled Project NENYA on Thursday. The platform is designed to help regional and midsize U.S. banks compete for stablecoin reserves. Tassat expects to launch it in early 2027 after pilot programs begin in the first half of 2026.
Smaller banks often lack the technology and compliance infrastructure needed to service stablecoin issuers. The platform connects regulated issuers with banks through a shared marketplace. Banks can bid for deposits. Issuers can spread reserves across institutions and monitor pricing and counterparty exposure.
Sussman said banks have told him: "We would love to participate in this. We don't have the infrastructure. We don't have the compliance. We wouldn't even know how to price these reserve deposits."
The announcement followed the passage of the GENIUS Act and a broader push by Wall Street into stablecoins. Goldman CEO backed the CLARITY Act as banks fight stablecoin rewards. Citi projects the stablecoin market could reach roughly $4 trillion by 2030.
At that scale, Sussman said, concentrating reserves among a few institutions could create liquidity and deposit risks. "If you assume stablecoins scale to $5 trillion or $10 trillion, then there has to be something that helps the market reach equilibrium," he said. "It can't just live in a really small circle because that will compound the risk on both sides."
The platform itself will not run on a blockchain. Tassat plans to connect it with tokenized asset and deposit networks. Sussman said that approach lowers the technical burden for smaller banks.
Sussman warned that without such a platform, smaller banks risk being left out. "There is a real risk that vast swaths of the U.S. banking ecosystem get left out in the cold," he said. "I don't think that's healthy politically for the United States. I don't think it's healthy economically."
Tassat expects to begin pilot programs in the first half of 2026 and launch the platform in early 2027.
