SAN FRANCISCO, September 17, 2026 —

‍Sardine, the leading agentic risk platform for fighting financial crime, today announced a partnership with Notabene, the trust layer for global money movement, to bring their industry-leading transaction authorization to Sardine's platform. Through the integration, Sardine customers can manage and automate their Travel Rule requirements and transaction authorization alongside fraud, KYC/KYB, AML transaction monitoring, and sanctions screening within a single, unified platform.

The partnership comes as regulatory clarity accelerates across the crypto and stablecoin industry with the EU’s Markets in Crypto-Assets Regulation and Transfer of Funds Regulation (MiCA/TFR), Brazil's BCB Resolution 520, and broader adoption of the Financial Action Task Force's Travel Rule standards giving companies the certainty to invest with confidence. That stability is drawing a new wave of fintechs and traditional financial institutions into the stablecoin market, and a rising demand to consolidate compliance infrastructure. 

The integration pairs Notabene's transaction authorization platform, and the largest network of regulated entities in the industry, with Sardine's risk platform to provide joint customers with a single point of access to both. This allows customers to not only manage Travel Rule requirements alongside the rest of their risk and compliance operations, but also feed transaction-level decisions back into Sardine to strengthen their overall risk management posture.

"Notabene has the deepest counterparty network in the industry, and now it's integrated directly into Sardine's platform. That means our customers can handle Travel Rule compliance alongside fraud, KYC/KYB, AML monitoring, and sanctions screening all in one place, without adding another vendor to manage.”
—Soups Ranjan, CEO and Co-Founder of Sardine

“Crypto and stablecoin companies shouldn’t have to choose between transaction-level or customer-level risk. Both are critical components of a robust compliance stack. By bringing our network and transaction authorization platform together with Sardine's, joint customers get real-time counterparty verification and transaction authorization running alongside the fraud and AML tools they already rely on, in one place." 
—Alice Nawfal, Co-founder and CEO of Notabene

Notabene's network connects thousands of trusted counterparties, facilitating trillions of dollars in transaction volume annually across more than 100 jurisdictions, extending the number of counterparties that customers can safely transact with, on the open-loop and ISO 20022-compatible Transaction Authorization Protocol. While Travel Rule compliance is the entry point for many of its customers, Notabene's core service is transaction authorization infrastructure, providing tools for stablecoin payment coordination, real-time transaction authorization, counterparty verification, and self-hosted wallet identification that help institutions increase their straight-through processing rates and build trust into every transaction. 

Sardine backs that network with a risk platform built to help crypto and stablecoin companies detect and stop financial crime across the customer lifecycle, from onboarding and KYC/KYB through transaction monitoring and sanctions screening.
