Notabene, operator of the world's largest open network for regulated on-chain transactions, has announced a strategic investment from Ripple, a leading provider of blockchain-based enterprise solutions spanning traditional and digital finance.

As part of the partnership, Notabene and Ripple will collaborate to expand enterprise stablecoin payments. The integration will bring Ripple USD (RLUSD) into Notabene Flow, Notabene's B2B stablecoin payments platform that provides payment coordination and authorization capabilities built on top of its scaled transaction authorization network. The two companies will also explore how trusted payment authorization can complement Ripple Payments.

By combining Ripple's global enterprise ecosystem and RLUSD stablecoin with Notabene's trusted institutional network — which currently facilitates over $2 trillion in annualized transaction volume — the partnership aims to accelerate adoption of compliant stablecoin payments. It also creates a pathway for RLUSD to be integrated across one of the world's largest institutional payment networks for digital assets.

To date, Notabene has built the largest open network for moving value on-chain safely, combining Travel Rule compliance with broader pre-transaction verification and authorization capabilities. The Travel Rule requires regulated virtual asset service providers to transmit identifying information about transaction originators and beneficiaries, making counterparty verification a central requirement for institutional digital asset transfers. The network spans more than 2,300 connected institutions, over 100 global jurisdictions, and 280-plus customers, including tier-1 banks, custodians, fintechs, and global exchanges. Through Notabene Flow, the company is extending its trust network and infrastructure into new capabilities for B2B and agentic stablecoin transactions, including pull payments, recurring payments, and automated invoicing solutions.

As financial institutions transition from stablecoin experimentation to production, they need to verify counterparty identities and transaction details before value moves, while meeting regulatory and internal risk requirements without introducing friction. That requirement is especially important for enterprise payments, where operational controls, sanctions screening, auditability, and payment authorization must fit existing compliance workflows. Notabene's trust network addresses this challenge, positioning it as a natural complement to Ripple's enterprise payments and stablecoin infrastructure.

"Stablecoins are quickly becoming part of mainstream financial infrastructure, but institutional adoption depends on more than efficient settlement rails alone," said Jack McDonald, SVP of Stablecoin at Ripple. "It requires trusted identity, compliance, and transaction authorization before value moves. Notabene's network addresses one of the fundamental barriers to enterprise adoption, and together we're helping build the compliant infrastructure institutions need to move value at global scale while expanding the utility of RLUSD."

Ripple's investment comes amid growing demand for regulated digital asset infrastructure, as banks, payment networks, fintechs, and new stablecoin consortia move to launch tokenized cash products and embed stablecoin rails into their existing offerings. Institutional momentum has been reinforced by growing regulatory clarity globally, including the passage of the GENIUS Act in the United States and MiCA in the European Union.

"Every institution I talk to has moved past whether to use stablecoins. They are stuck on how to do it safely at scale within the context of their existing business," said Pelle Braendgaard, Co-Founder and CEO of Notabene. "They need to know who is on the other side, what the transaction is for, and how to authorize payments without adding friction. That is what Notabene and its network of regulated institutions solve. Paired with an enterprise-ready stablecoin like RLUSD and Ripple's global payments reach, it turns compliant stablecoin payments from a pilot into a real growth engine that reaches more counterparties and moves more volume, faster."

With the investment, Notabene will leverage Ripple's enterprise ecosystem to accelerate the rollout of Notabene Flow, extending compliant stablecoin payments to institutions worldwide. Establishing strategic partnerships is a core pillar of Notabene's strategy for scaling Notabene Flow, and the company expects to bring on other leading financial institutions over the coming quarters.
