ZK Proof API Gateway
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- From Concept to Mainnet: Full lifecycle support from initial design and
Solidity/Rustdevelopment to deployment and monitoring onEthereum,Solana, orPolygon. - Compliance & Standards: Built-in support for
ERC-20,ERC-721,ERC-1155, and other standards, with custom logic for governance (ERC-20Votes) and access control. - Guaranteed Quality: Every contract undergoes rigorous unit testing, static analysis with
Slither/MythX, and a formal review before delivery.
We deliver battle-tested code that executes as intended, protecting your assets and your users' trust. Reduce your time-to-market with production-ready contracts in as little as 2 weeks.
Core Capabilities of Our Managed Gateway
Our fully managed ZK Proof API Gateway delivers production-ready infrastructure, allowing your team to focus on core product logic while we handle the cryptographic complexity, security, and scaling.
High-Performance Proof Generation
Generate ZK proofs for complex circuits in under 2 seconds with our optimized proving backends. We support Groth16, Plonk, and Halo2 with automatic hardware acceleration for consistent, low-latency performance critical for real-time applications.
Zero-Knowledge Security & Audits

Scalable Multi-Chain Verification
Verify proofs seamlessly across Ethereum, Polygon, Arbitrum, and other EVM-compatible networks. Our gateway manages verifier contract deployments, gas optimization, and cross-chain state synchronization, abstracting away blockchain complexity.
Managed Circuit Deployment
From R1CS to on-chain verifier. We handle the entire lifecycle of your ZK circuits: compilation, trusted setup coordination (PPOT or perpetual), verifier contract generation, and secure deployment to your specified networks.
Real-Time Monitoring & Analytics
Gain full visibility into your ZK workload with detailed dashboards. Monitor proof generation latency, success rates, verifier gas costs, and system health with actionable alerts and logs to ensure optimal performance and cost management.
Business Outcomes You Can Measure
Our ZK Proof API Gateway delivers quantifiable improvements to your development lifecycle and operational security. These are the metrics that matter to your business.
Accelerated Time-to-Market
Deploy privacy-preserving features in weeks, not months. Our managed gateway abstracts the complexity of zero-knowledge cryptography, allowing your team to focus on core product logic.
Provable Security & Compliance
Leverage pre-audited ZK circuits and a gateway built on OpenZeppelin security patterns. Generate cryptographic proof of compliance for data privacy regulations without exposing sensitive inputs.
Predictable, Scalable Costs
Eliminate the overhead of managing ZK prover infrastructure. Our usage-based API model converts large capital expenditures into a predictable operational cost that scales with your transaction volume.
Enterprise-Grade Reliability
Maintain business continuity with a fault-tolerant, multi-cloud gateway. We guarantee the uptime and consistency required for financial applications and high-volume dApps.
Developer Velocity & Retention
Provide your engineering team with a clean, documented REST/GraphQL API instead of forcing them to master niche ZK tooling (Circom, Halo2). Reduce onboarding time and improve job satisfaction.
Enhanced User Trust & Adoption
Enable features like private transactions and identity verification without compromising UX. Users get the benefits of blockchain verification with the simplicity of a web2 login.
Applications Powered by ZK Proof APIs
Our ZK Proof API Gateway enables you to integrate advanced cryptographic privacy and scalability directly into your core product. These are the proven applications our clients are building today.
Private Identity & Compliance
Verify user credentials (KYC/AML) without exposing sensitive data. Build compliant DeFi or on-chain gaming platforms that protect user privacy while meeting regulatory requirements.
Key Differentiator: Our APIs handle the complex ZK circuit generation, so you can focus on user experience.
Scalable Layer 2 Bridges
Generate succinct validity proofs for cross-chain asset transfers. Our gateway provides the proving infrastructure to build secure, trust-minimized bridges with fast finality.
Client Outcome: Reduce bridge settlement times from hours to minutes while maintaining cryptographic security guarantees.
Confidential DeFi Transactions
Enable private swaps, loans, and liquidity provision. Shield transaction amounts and participant identities on public ledgers to protect strategic trading positions and user financial data.
Technical Depth: Built with circuits optimized for EVM-compatible chains and Solana.
Verifiable Off-Chain Computation
Offload complex calculations (like ML inference or game logic) off-chain and submit a verifiable proof of correct execution. Maintain decentralization without sacrificing performance.
For: Web3 gaming, prediction markets, and decentralized AI applications.
Audit Trail & Data Integrity
Create immutable, verifiable logs for supply chain, healthcare, or enterprise data. Prove the integrity and sequence of events without revealing the underlying confidential records.
Enterprise Value: Provides a cryptographically secure single source of truth for auditors and regulators.
Wallet & Transaction Privacy
Implement stealth addresses, confidential transactions, and privacy pools directly into wallets or dApps. Our APIs abstract the complexity of ring signatures and zero-knowledge membership proofs.
Why Chainscore: We provide the proving infrastructure, so you don't need to build and maintain your own trusted setup ceremony.

Post-launch, we provide dedicated support with defined SLAs for incident response. Our team monitors proof generation latency, API health, and system costs, offering optimization recommendations to ensure long-term efficiency.
Frequently Asked Questions
Common questions from CTOs and engineering leads evaluating zero-knowledge infrastructure.
Standard integration takes 1-2 weeks from contract signing to production-ready deployment. This includes environment setup, API key provisioning, and a pilot transaction flow. For custom circuit development or integration with novel state models, the timeline extends to 4-6 weeks based on complexity.
