Portal Labs joins Notabene Flow as a founding partner

Today, onchain transfers work like one-way pushes. They’re fast, but they don’t include the checks, authorization, or safeguards that businesses rely on every day. Without those, stablecoins can’t handle critical workflows like invoices, supplier payments, or large-scale settlements.

‍

That’s where Notabene Flow comes in.

‍

Flow is a new open network that provides the missing layer of trust and coordination on top of stablecoins. By embedding compliance, verified counterparties, and standardized authorization into the payment process, it gives enterprises what they’ve been waiting for: digital assets they can actually use at scale.

What makes Flow different

Instead of ad hoc integrations and manual checks, Flow introduces a shared framework that works across chains, assets, and jurisdictions. Key features include:

• Machine-readable authorization through TAP (Transaction Authorization Protocol), replacing free-text payment instructions with structured approvals.
• Deterministic identity checks using LEI/GLEIF anchors so counterparties are verified and auditable.
• Compliance baked in with Notabene’s Travel Rule network ensuring transactions meet global standards before funds move.
• Open-loop architecture that avoids closed systems, allowing anyone to connect.
• Aligned incentives with revenue-sharing and competitive economics for participants.

The outcome: more successful transactions, fewer errors, and rails that finally make sense for high-value B2B payments.

Portal’s role in the network

At Portal Labs, our mission is to make stablecoin payments simple and secure for developers and institutions alike. Within Flow, we provide the embedded wallet infrastructure that ensures every payment can be executed reliably and compliantly.

• Wallets at the core: Our infrastructure lets initiators and responders transact directly from embedded wallets tailored to their applications.
• Gas abstraction: We handle the complexity of fees so payments move seamlessly without friction.
• Compliance-ready APIs: Our orchestration layer works hand-in-hand with Flow’s trust framework, making sure payments are signed only after the right checks are passed.
• Developer simplicity: One integration brings secure signing, policy enforcement, compliance, and execution into any product.

By combining Notabene Flow’s trust rails with Portal’s developer-first infrastructure, we’re opening the door to stablecoin use cases that have never been practical before:

💼 Automated supplier payments

🌍 Cross-border trade flows

🏦 Treasury and cash management at enterprise scale

Why it matters

Businesses don’t just need speed, they need predictability, auditability, and resilience. Notabene Flow delivers that, and Portal helps make it usable by anyone building with stablecoins.

Together, we’re turning stablecoins from a promising asset into a true payment network for global business.
