>_ Why Cipher

Flexible privacy tooling for EVM apps

Cipher gives teams reusable contracts for building confidential workflows without designing privacy infrastructure from scratch.

Keep Data Private

Protect sensitive inputs, transaction details, and app data onchain.

Verify Without Revealing

Prove eligibility, validity, and rules without exposing the underlying data.

Built for Real Use Cases

Apply the right privacy model to governance, payments, auctions, RWAs, and more.

Contracts First

Integrate through reusable contracts today, with SDK support as the product expands.

>_ How Cipher Works

Confidential execution, made practical

Cipher combines privacy, verification, and execution into flows developers can actually use.

Choose a Toolkit

Start with a privacy flow built for your use case.

Protect the Data

Cipher applies proofs and encryption before execution.

Verify Onchain

Contracts validate the action without exposing sensitive data.

Run Securely

Your app executes with privacy and verification built in.

>_ Use Cases

Built for high-value confidential workflows

Cipher is designed for application areas where privacy and verification matter most.

Confidential Governance

Private voting and encrypted tallying with onchain rule enforcement.

Private Payroll

Protect salary, bonus, and payout data from public exposure.

Confidential Markets

Support sealed bids, private offers, and protected price discovery.

Private RWA Flows

Verify access and compliance without exposing identity or financial data.

>_ Trusted Foundations

Built on proven cryptography infrastructure

Cipher combines well-tested tools for zero-knowledge proofs and homomorphic encryption, giving developers strong privacy and verification without building cryptographic systems from scratch.

Noir-Powered Proofs

Trusted ZK circuits for validation, eligibility, and rule enforcement.

Zama-Backed Encryption

Encrypted computation powered by proven FHE infrastructure.

Ready to Integrate

Delivered through reusable contracts built for existing EVM workflows.

>_ Why Teams Choose Cipher

A simpler way to add privacy

Cipher packages the right privacy architecture into reusable contracts so teams can move faster.

No Chain Migration

Bring confidentiality to existing EVM apps without moving contracts or assets.

Less Crypto Complexity

Avoid building circuits, encrypted flows, and privacy logic from scratch.

Flexible by Domain

Use toolkits designed for real app categories, not one generic privacy layer.

Easy to Integrate

Adopt through reusable contracts with a simple developer workflow.
