Privacy-Preserving Voting Integration SDK
We develop and integrate SDKs that enable private, on-chain voting using zero-knowledge proofs. Voter choices are concealed while results remain cryptographically verifiable, ensuring both confidentiality and integrity for DAOs and enterprise governance.

overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts for DeFi, NFTs, and enterprise applications.
From a single custom token to a complex multi-contract system, we deliver code you can stake your business on.
- Full Lifecycle Development: Strategy, architecture,
Solidity/Rustdevelopment, testing, deployment, and maintenance. - Security-First Approach: Comprehensive audits, static analysis, and automated testing to mitigate vulnerabilities before mainnet launch.
- Protocol-Specific Expertise:
ERC-20,ERC-721,ERC-1155,ERC-4626, custom staking, governance, and cross-chain bridges.
Our contracts are built for real-world use: gas-optimized for efficiency, upgradeable for future-proofing, and fully documented for your team. We ensure compliance with relevant standards and provide a clear handoff process.

ENTERPRISE-READY
Core Capabilities of Our Voting SDK
Our SDK provides the foundational privacy, security, and flexibility required to build compliant and trusted voting applications on-chain. We handle the cryptographic complexity so you can focus on governance.
02
Multi-Chain & L2 Agnostic
Deploy your voting mechanism on Ethereum, Polygon, Arbitrum, or any EVM-compatible chain. Our SDK abstracts chain-specific logic, ensuring your governance layer is portable and future-proof.
04
Flexible Voting Models
Support for token-weighted, quadratic, conviction, and delegated voting out-of-the-box. Easily customize proposal lifecycle, quorum rules, and voting periods to match your DAO's specific needs.
05
Gas-Optimized Execution
Engineered for cost-efficiency with gas-optimized smart contracts and batch processing for vote aggregation. Reduce on-chain transaction costs for your voters by up to 40% compared to naive implementations.

PROVEN METHODOLOGY
Our Delivery Process: From Audit to Integration
A structured, security-first approach to delivering production-ready privacy-preserving voting. We manage the entire lifecycle from initial code review to seamless API integration, ensuring reliability and compliance.
01
Comprehensive Security Audit
We begin with a deep-dive audit of your existing voting logic and smart contracts. Our team identifies vulnerabilities, gas inefficiencies, and compliance gaps against standards like ERC-20/721 and ZK-SNARK implementations.
