FULL-STACK BUILD
Custom Blockchain Development
End-to-end development of custom blockchains and Layer 2 solutions tailored to your specific use case.
Move from concept to a live, secure network in as little as 8-12 weeks with our proven development framework.
Our full-cycle service includes:
- Consensus & Protocol Design: Custom
Proof-of-Stake,Proof-of-Authority, or hybrid models. - Node Infrastructure: Deployment of validator sets, RPC endpoints, and block explorers.
- Smart Contract Suite: Core protocol logic, governance, and utility contracts in
Solidity,Rust, orMove. - Cross-Chain Bridges: Secure, audited bridges to Ethereum, Polygon, and other major networks.
We focus on long-term viability. Every deployment includes comprehensive documentation, node operator tooling, and a clear upgrade path. Our clients launch with enterprise-grade infrastructure capable of handling thousands of TPS and millions of users.

DELIVERABLES
Business Outcomes for Your Platform
Our privacy-preserving withdrawal service delivers measurable results that directly impact your platform's security, compliance, and user growth.
01
Regulatory Compliance by Design
ZK-proofs enable selective disclosure for AML/CFT checks, allowing you to meet global standards like FATF Travel Rule without exposing full transaction graphs. We integrate with compliance partners for automated reporting.

Architectural Comparison
ZK Withdrawals vs. Conventional Transaction Monitoring
A technical breakdown of how privacy-preserving ZK withdrawals fundamentally differ from traditional transaction monitoring systems, highlighting key advantages for compliance and user experience.
| Feature / Metric | Conventional Transaction Monitoring | Chainscore ZK Withdrawals |
|---|---|---|
Privacy Model | Transparent (All data on-chain) | Private (Zero-knowledge proofs) |
Compliance Overhead | High (Manual KYC/AML per withdrawal) | Low (ZK-proof of compliance) |
User Experience | Cumbersome (Delays for checks) | Frictionless (Instant, private settlement) |
On-Chain Data Leakage | High (Exposes wallet links, amounts) | None (Only proof validity is published) |
Regulatory Audit Trail | Raw transaction history | Cryptographically verifiable proof of compliance |
Implementation Time | 3-6 months (integration + rules engine) | 4-8 weeks (SDK integration) |
Ongoing Operational Cost | High (Monitoring fees, manual review) | Predictable (Fixed proof generation cost) |
Supported Standards | N/A | Semaphore, RLN, Custom ZK-circuits |

PROVEN METHODOLOGY
Our ZK Development & Integration Process
A systematic, security-first approach to integrating privacy-preserving withdrawals, designed for rapid deployment and enterprise-grade reliability.
01
Architecture & Circuit Design
We design custom zk-SNARK or zk-STARK circuits tailored to your withdrawal logic, ensuring optimal proof generation time and gas efficiency on-chain. This includes selecting the right proving system (Groth16, Plonk, Halo2) for your use case.
2-4 weeks
Design Phase

Frequently Asked Questions
Get clear, specific answers about our zero-knowledge withdrawal development process, security, and support.
A standard, production-ready ZK withdrawal system takes 4-8 weeks from kickoff to mainnet deployment. This includes circuit design, smart contract development, comprehensive security audits, and integration with your frontend. For more complex requirements like custom proving schemes or multi-chain support, timelines are scoped individually.
