Sui unveils Tessera, a private B2B settlement network for institutional transactions

Sui has unveiled Tessera, a business-to-business payments and settlement network designed to keep transaction amounts private, according to an announcement on its official X account. The prototype aims to address a long-standing barrier to blockchain adoption in institutional finance: the public visibility of transaction details.

Why privacy matters for institutional settlement

Institutions are often reluctant to settle trades on infrastructure where competitors can see prices and volumes, Sui explained. Most blockchains disclose transaction amounts transparently, which has discouraged real-world B2B payments from moving on-chain. Tessera is built to change that by leveraging Seal MPC and confidential transfers, enabling counterparties to transact privately while still allowing regulators and other authorized parties to view transaction information as needed.

The announcement highlights a growing demand for privacy-preserving blockchain solutions in traditional finance. While public blockchains offer transparency and auditability, that same transparency can be a liability for businesses that need to protect commercially sensitive data. Tessera’s approach could offer a middle ground, maintaining the benefits of distributed ledger technology without exposing proprietary financial information.

How Tessera works

Tessera uses multi-party computation (MPC) through Seal MPC to enable confidential transfers. This cryptographic technique allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. In the context of settlement, it means transaction amounts can be validated and recorded without being publicly disclosed.

The network is designed to give authorized parties—such as regulators, auditors, or compliance officers—selective access to transaction details. This selective disclosure is critical for meeting regulatory requirements while preserving commercial confidentiality.

Implications for institutional adoption

The introduction of Tessera signals a broader trend in the cryptocurrency and blockchain industry: the pivot toward institutional-grade infrastructure. As more traditional financial institutions explore digital assets, they require networks that can accommodate their operational and compliance needs. Privacy is often cited as a key requirement, and Tessera’s design directly addresses that.

If successful, Tessera could pave the way for greater blockchain use in intercompany settlements, trade finance, and other B2B applications where confidentiality is paramount. It also positions Sui as a serious contender in the race to provide enterprise-ready blockchain solutions.

Conclusion

Sui’s Tessera represents a meaningful step toward reconciling blockchain transparency with institutional privacy needs. By enabling confidential transfers while preserving authorized oversight, it could unlock new use cases for distributed ledger technology in business-to-business payments. The prototype will be closely watched by industry participants eager to see whether privacy-focused settlement networks can gain traction in the traditional financial sector.

FAQs

Q1: What is Tessera?
Tessera is a B2B payments and settlement network built on Sui that keeps transaction amounts private using confidential transfers and Seal MPC technology.

Q2: Why is privacy important for B2B blockchain payments?
Institutions need to keep pricing and volume data confidential to maintain competitive advantage. Public blockchains expose this information, hindering adoption for real-world business transactions.

Q3: How does Tessera balance privacy and regulatory compliance?
Tessera allows authorized parties, such as regulators, to view transaction details as needed, while keeping them hidden from the public and competitors.
