# Notabene

> The open trust layer for global payments

Notabene is a compliance and stablecoin payments platform that helps financial institutions and crypto businesses meet Travel Rule requirements.

Notabene is a compliance and payments company that provides pre-transaction authorization and counterparty verification for regulated institutions moving digital assets. It serves crypto exchanges, banks, payment providers, and custodians that need to screen counterparties, exchange required personal data, and apply jurisdiction-specific rules before a transaction settles. The platform is built for organizations handling cross-border digital asset flows who must demonstrate compliance with anti-money laundering rules such as the Travel Rule.

The platform addresses a structural problem in digital asset compliance: transferring the personal data required by regulators between counterparties without a shared, verified network of institutions. Notabene operates an open network of verified virtual asset service providers and financial institutions, allowing members to look up counterparties, exchange encrypted compliance data, and verify ownership of self-hosted wallets. Its Transaction Authorization Protocol coordinates this authorization process across multiple blockchains and wallet providers rather than relying on a single proprietary rail.

Its product set spans Notabene Flow, an open stablecoin payments offering, and Notabene Transact, a transaction authorization platform for complex digital asset flows, alongside network and counterparty verification tools. These products are used by exchanges, banks, payment service providers, and custodians that need to move stablecoins and other digital assets across borders while maintaining regulatory standing. The company is licensed to provide compliance services in the jurisdictions where it operates.

## Products

- [Notabene Transact](https://thegrid.id/profiles/notabene): Notabene Transact is a pre-transaction compliance platform for virtual asset service providers and financial institutions. It automates Travel Rule requirements by screening counterparties, performing due diligence, running risk-based transaction authorization, and exchanging encrypted personal data across multiple Travel Rule messaging protocols. Embedded components handle escrowed encryption of personal data, self-hosted wallet ownership verification, and interoperability across otherwise incompatible Travel Rule protocols, while a shared counterparty network extends reachability across institutions. The platform applies decentralized identifiers and verifiable credentials alongside configurable, jurisdiction-specific compliance rules. (Onchain Compliance and Investigations, Live, Main Product)
- [Notabene Flow](https://thegrid.id/profiles/notabene): Notabene Flow is a stablecoin payment infrastructure network for wallets, issuers, fintechs, and payment service providers. It coordinates pull payments such as merchant-initiated invoices, push payments such as sender-initiated payouts, and recurring billing cycles for business commerce. The network relies on an open authorization protocol to verify identities, enforce compliance policy, and authorize settlement across payment agents before funds move on-chain. Participants integrate as payment-initiating agents, payment-responding agents, or infrastructure providers through application programming interfaces, and the network coordinates and authorizes transactions without holding funds or acting as a custodian. (Payments Infrastructure & Orchestration, Early access)
- [TAP (Transaction Authorization Protocol)](https://thegrid.id/profiles/notabene): Transaction Authorization Protocol is an open-source, blockchain-agnostic protocol for coordinating payment authorization before on-chain settlement. It defines how counterparties exchange signed transfer requests and communicate through encrypted messaging to verify identities, enforce compliance policies, and authorize transactions before funds move. Parties, agents, and infrastructure systems interact through the protocol layer across any wallet, exchange, or smart contract, and it underpins the authorization flows used by other Notabene products. The protocol evolves through community-governed improvement proposals and is not controlled by any single company. (Messaging Protocol, Live)
