Tessera by Sui: A New Era for Confidential B2B Settlements

Sui has introduced Tessera, a dedicated settlement network designed for business-to-business transactions. Moving beyond basic payment rails, Tessera addresses a critical pain point in corporate finance: how to keep transaction amounts confidential while remaining fully compliant with audit and regulatory requirements.

Core Technology: Privacy That's Verifiable

The network's privacy features are powered by a dual-layer technical approach:

  • Seal MPC (Secure Multi-Party Computation): Allows participants to jointly compute settlements without revealing sensitive input data.
  • Sui's Native Private Transfer: Provides transaction amount privacy at the blockchain layer, limiting visibility of payment details.

This architecture ensures transaction specifics remain hidden from unrelated parties on the network. However, authorized auditors can still cryptographically verify transactions for compliance, creating a practical balance between confidentiality and necessary transparency.

Governance and Control for Enterprise Consortia

Recognizing the needs of managed business networks, Tessera equips operators with essential administrative controls. These include the ability to:

  • Manage member onboarding and approval
  • Configure fund flow parameters
  • Freeze individual member accounts or suspend the entire network if required

This layer of governance provides the operational resilience and risk management capabilities expected in professional financial infrastructure.

Built for Real-World Business Operations

Tessera supports flexible payment types to accommodate various commercial workflows:

  • One-time transfers for ad-hoc settlements.
  • Recurring payments for payroll, vendor fees, or subscriptions.

The system also incorporates a dispute resolution mechanism. Conflicting parties can escalate transactions to a designated arbitrator, adding a layer of security for complex agreements.

The project's codebase is now open-source, inviting developer scrutiny and collaboration. This move aims to foster trust and accelerate innovation in the field of privacy-preserving enterprise settlement solutions.
