Features

Why Choose zkSign

Built for developers who demand privacy, performance, and security without compromise

Privacy First

Zero-knowledge proofs ensure your data remains completely private while still being verifiable on-chain.

Lightning Fast

Built on Solana for sub-second finality and high-throughput proof verification at scale.

Battle-Tested Security

Cryptographic primitives audited by leading security firms to ensure your data is always protected.

Cost Effective

Leverage Solana's low transaction fees to verify proofs at a fraction of traditional blockchain costs.

How It Works

Privacy in Four Steps

Implement zero-knowledge proofs in your Solana applications with our simple, secure workflow

1

Generate Proof

User signs data off-chain while keeping real data hidden.

2

Submit Zero-Knowledge Proof

Browser generates zkSNARK/Halo2 proof without sending raw data.

3

On-chain Verification

Solana program validates the proof.

4

Attestation Ready

Proof becomes reusable for DeFi, DAO, identity checks, etc.

Use Cases

Endless Possibilities

From DeFi to identity verification, zkSign enables privacy-preserving applications across the Solana ecosystem

DeFi Privacy

Prove creditworthiness or asset ownership without revealing wallet balances or transaction history.

Identity Verification

Verify age, citizenship, or credentials without exposing personal information to third parties.

DAO Governance

Enable private voting and token-weighted proposals while maintaining transparency and auditability.

Compliance & KYC

Meet regulatory requirements with privacy-preserving compliance checks and attestations.

Social Platforms

Build reputation systems and social graphs without compromising user privacy or data ownership.

Data Marketplaces

Prove data integrity and ownership while keeping sensitive information encrypted and private.

FAQ

Frequently Asked Questions

Everything you need to know about zkSign and zero-knowledge proofs

Zero-knowledge proofs (ZKPs) are cryptographic methods that allow one party to prove to another that a statement is true, without revealing any information beyond the validity of the statement itself. In zkSign, this means you can prove you own an asset or meet certain criteria without exposing your private data.
Integration is simple with our SDK. Install via npm, import the library, and use our pre-built functions to generate and verify proofs. Complete documentation and code examples are available in our GitHub repository and docs section.
Thanks to Solana's efficient architecture, zkSign verification costs are minimal - typically less than $0.001 per proof verification. This makes it economically viable for high-volume applications.
Yes, zkSign's smart contracts and cryptographic implementations are currently undergoing audits by leading security firms. Audit reports will be published upon completion in Q2 2026.
zkSign is currently in devnet testing phase. Mainnet deployment is planned for Q3 2026 after comprehensive security audits and community testing. You can start building and testing on devnet today.
Our SDK supports TypeScript/JavaScript for browser and Node.js environments. We're also working on Rust and Python SDKs for broader language support in future releases.
