Fairblock enables confidential transfers on public blockchains where transaction amounts and balances are encrypted by default, while preserving performance, usability, and compliance requirements. The system is designed to support financial institutions, neobanks, payroll providers, and trading firms that require privacy without introducing operational complexity or new trust assumptions. The design separates confidentiality from anonymity. Confidentiality is always enabled and ensures that transaction amounts and balances remain encrypted. Anonymity is optional and can be enabled for partners or flows that require it in KYB/KYC-scoped environments. This mirrors how encryption is universally used on the internet, while stronger privacy tools are applied selectively.

​
Defining Confidential Transactions

Amounts and balances are encrypted while addresses stay transparent. This combination lets you:
  • Support DeFi composability and integrations
  • Stay traceable for audits
  • Selectively disclose only what’s needed on a transaction-level, only when it is required.
It is not a mixer and not an anonymity pool. It is programmable confidentiality built for legitimate businesses and finance. This approach aligns with the model BIS, ECB, IMF, and others are describing for next-generation payment systems.

​
Core Applications

  • Confidential salaries for employees, contractors, and KOLs
  • Private peer-to-peer, cross-border, and merchant payments
  • Integration with payment networks for compliant, confidential settlements
No one wants comp, vendor rates, or partner payouts scraped and indexed. That’s HR liability, competitive intelligence leakage, and reputational risk.
  • Encrypted orderflow and resistant to manipulation (e.g. frontrunning)
  • Confidential liquidity, collateral, and position management
If the market can see size and timing, you’re handing a competitive edge to competitors and bots. Confidential amounts stop your orders from working against you.
  • Managing onchain VC liquid funds, corporate, DAO, and fund treasury operations
  • Confidential inter-subsidiary and OTC settlements
Treasury activity is strategy. Get the benefits of moving funds onchain without broadcasting your strategy to the entire market.
  • Private acquisitions and token buyouts without market leaks
  • Pre-announcement confidentiality and selective auditability
Onchain corporate actions expose you to frontrunners. They also create legal and regulatory questions if markets react before disclosure windows.
  • Tokenized securities trading (equities, bonds, funds)
  • Institutional settlement workflows (custody, issuance, venues)
Enable confidential trading and settlement of tokenized securities without exposing portfolio composition or execution terms on public chains. Designed to fit the operational needs of custodians, issuers, and market venues.
  • Selective disclosure and bad actor filtering
  • Anti-money laundering (AML)-safe stablecoins and regulatory auditability
  • Protection against GDPR/MiCA/CCPA/Clarity related data exposure risk for institutions
Regulators increasingly expect two things: don’t expose everything to everyone, and do let authorized parties verify under lawful authority. Fairblock follows this exact model. You can disclose a specific transaction, and only that transaction, to a tax authority, regulator, or auditor without revealing your entire financial history. This maps to how financial supervisors describe acceptable digital asset systems and how TradFi already handles sensitive trade and payments data.
  • Privacy-preserving credit, lending, and agentic payments
  • Selective-disclosure rails for payment networks, issuers, and banks
You can’t run credit or agent-to-agent payments if every invoice, fee, and settlement is globally visible. Confidential rails are the prerequisite. With selective disclosures, regulated parties settle onchain and can still produce per-transaction details for compliance.

Why Fairblock

Performance

Sub-second client-side. Lightweight cryptography runs on the user side without introducing latency or external proving infrastructure.

Decentralization

No trusted hardware. The system does not rely on TEEs, trusted coprocessors, or centralized proving services.

Usability

No new wallets or keys. End users interact with their existing wallets. Keys are derived on demand, never stored.

Compliance

Selective disclosure. Confidentiality-by-default with controlled, post-execution access for authorized parties.
