Notabene

Notabene develops infrastructure for compliant digital-asset transactions and stablecoin payments. The company describes its offering as a trust layer that connects financial institutions and other regulated organizations so they can coordinate and verify transactions before funds move. Its stated mission is to make crypto transactions part of the everyday economy.

The company’s products span a protocol, network, and software interface. Notabene Flow is presented as a stablecoin payments platform for businesses, supporting payment requests and invoices, payouts, and recurring billing. Notabene Transact provides transaction authorization and embedded compliance workflows, including real-time decision-making and audit-ready reporting.

Notabene also develops the Transaction Authorization Protocol (TAP), an open protocol for exchanging pre-transaction messages. The company says TAP standardizes how counterparties discover, validate, and authorize crypto transactions before funds move, using signed transfer requests and encrypted messaging. Its stated aim is to support interoperability across platforms and networks.

A central part of Notabene’s work is helping financial institutions and virtual asset service providers address Travel Rule requirements. Its software supports counterparty identification and screening, risk assessment, information exchange, and transaction-flow automation. The company also describes capabilities for sanctions screening, identifying self-hosted wallets, and generating regulatory reporting records. Notabene says its network includes more than 2,300 regulated institutions and reaches over 110 jurisdictions.

Notabene identifies exchanges, custodians, banks, wallet providers, stablecoin issuers, payment service providers, fintechs, and payment networks among the institutions its infrastructure is built to serve. On its website, it presents the network as a way for participating organizations to exchange value with verified counterparties while incorporating compliance checks and transaction context into payment flows.

Notabene says it was established in 2020, in response to challenges including implementation of the FATF Crypto Travel Rule. The company’s account of its origins connects the founders’ earlier experience with Bitcoin startups—and the regulatory uncertainty those ventures encountered—to its goal of building a trusted data layer for crypto transactions. It says its founding team brings experience in banking infrastructure, identity, blockchain, crypto financial products, data integration, product design, and user experience.

The company describes security, privacy, and end-user experience as priorities in its platform design. Its broader vision is to make crypto a natural and secure part of financial transactions, while simplifying global regulatory compliance. Notabene’s website also lists a distributed team, with teammates in multiple countries and a range of languages represented; it does not provide detailed information about specific workplace policies or employee culture.
