Cloak by Scroll does to Web3 what HTTPS did to the web. Upgrade any EVM application with verifiable confidentiality, deployed as a managed service.
Real Failures of Public Blockchains
Why institutions can't operate on transparent blockchains
"Every DeFi protocol can see competitor moves in real-time."
Public balances and transaction history expose treasury strategies, liquidity positions, and trading patterns. This is why institutions moved off-chain or to private networks.
Cloak solution: Encrypted balances + selective disclosure
"GDPR Article 17 is incompatible with immutable public chains."
The "right to be forgotten" cannot be enforced on permanent public ledgers. European banks and enterprises cannot use public blockchains for customer data without violating GDPR.
Cloak solution: Auditor-ready compliance + data privacy controls
Cloak is doing to Web3 what HTTPS did to the web
Upgrade any EVM application with verifiable confidentiality, deployed as a managed service with zero infrastructure overhead.
Enterprise-Grade Access Control
Integrate confidentiality with your existing identity infrastructure. Control who sees what, without code changes.
Use your existing identity provider. Integrate with Okta, Auth0, Azure AD, or any SAML/OIDC provider. No new authentication system required.
- Single Sign-On (SSO) with Okta, Google Workspace, Microsoft
- Web3 wallet integration (Sign-In with Ethereum)
- Multi-factor authentication (MFA) support
Define who sees what. Set granular permissions at the function, contract, or data field level. Update policies in real-time.
- Function-level access control (admin, trader, viewer)
- Dynamic policy updates without redeployment
- Audit trails for all permission changes
Manage access without writing code. Add users, assign roles, configure permissions through an intuitive admin console.
- User and group management interface
- Real-time permission assignment
- Activity monitoring and alerts
Share specific data with auditors. Generate proof keys that reveal only what regulators need to see, without exposing everything.
- Time-bound auditor access with automatic expiry
- Field-level disclosure (show amount, hide counterparty)
- Cryptographic proof of disclosure integrity
Built for compliance teams, not just developers
Your legal and operations teams can manage access policies directly. No engineering bottleneck. No smart contract redeployment required.
Why Confidentiality Matters
In finance and enterprise environments, information must be protected, but never hidden from accountability. Most blockchain systems make you choose between transparency for auditors and confidentiality for users. Cloak removes that compromise.
Add confidential transactions directly on any EVM chain. No new infrastructure needed.
Use Solidity, Hardhat, and your current stack. Cloak extends, not replaces, your workflow.
Share encrypted data only with trusted reviewers. No loss of oversight or compliance.
Two Paths to Auditable Confidentiality
Add confidential transactions and proofs to your existing app or protocol. Ideal for stablecoins, real-world assets (RWAs), DAOs, and DeFi that need confidentiality without running new infrastructure.
- Deploy on any EVM chain (Ethereum, Polygon, Base, etc.)
- 2–4 week deployment timeline
- Zero infrastructure management
For institutions requiring isolation, Nexora deploys a dedicated chain with Cloak confidentiality. Full control, allowlists, Ethereum anchoring, and managed SOC2-ready operations.
- Dedicated infrastructure with full control
- 6–8 week deployment timeline
- Managed SOC2-ready operations
"Just as HTTPS secured the insecure web, Cloak brings verifiable confidentiality to every Web3 application. Every dapp will offer verifiable confidentiality."
Enterprise-Grade Controls
Allowlists and policy gates for comprehensive access control.
Audit explorer and event export with complete transparency for authorized parties.
Bring-your-own KMS and seamless compliance tooling.
Developer-First by Design
The Cloak SDK makes confidentiality a native part of EVM workflows. Deployed as a managed service by NEXORA, developers can issue confidential transactions, create proofs, and design selective-disclosure dashboards using standard Ethereum tools.
No infrastructure complexity. No new deployment requirements. Just add confidentiality to your existing stack.
Proven Infrastructure. Trusted Partners.
Cloak combines Scroll's zkEVM scalability with Nexora's enterprise operations to deliver verifiable, compliant confidentiality. Serving everyone, from startup protocols to institutional deployments.
"Every Web3 dapp will offer verifiable confidentiality. Cloak is making that future inevitable."
Confidentiality Controls
- Zero-knowledge proofs
Every transaction is cryptographically sealed — only authorized parties can read the contents.
- Auditable by authorized parties
Time-bound auditor access with automatic expiry.
- Plugin layer compatibility
Deploy on any EVM chain (Ethereum, Polygon, Base, etc.).
- SSO, RBAC, compliance — deployed as a managed service
Single Sign-On (SSO) with Okta, Auth0, Azure AD; MFA support; function-level access control; audit trails for all permission changes.
- Auditor-ready controls
Cryptographic proof of disclosure integrity.
- Control who sees what
Field-level disclosure (show amount, hide counterparty).
- Works with your stack
Use Solidity, Hardhat, and your current stack. Cloak extends, not replaces, your workflow.
