overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From token standards like
ERC-20,ERC-721, andERC-1155to complex DeFi primitives, we deliver contracts that are ready for scale.
- Full Lifecycle Support: Strategy, development, testing, deployment, and post-launch monitoring.
- Security-First Approach: Built with
OpenZeppelinlibraries and following industry best practices. - Multi-Chain Expertise: Deployments on Ethereum, Polygon, Arbitrum, Base, and other EVM-compatible chains.
We focus on developer experience and maintainability, delivering clean, well-documented Solidity/Vyper code. This reduces long-term technical debt and accelerates future feature development for your team.

PROVEN FRAMEWORK
Our Privacy Wallet Audit Methodology
A systematic, multi-layered approach to securing privacy-preserving wallets, designed to identify critical vulnerabilities before they impact your users or assets.
01
Architecture & Design Review
We analyze your wallet's core architecture, cryptographic primitives (zk-SNARKs, zk-STARKs, stealth addresses), and privacy model for fundamental flaws in logic or implementation.

02
Smart Contract & Circuit Audit
In-depth manual and automated review of on-chain contracts (e.g., privacy pools, mixers) and zero-knowledge circuits for correctness, soundness, and gas optimization vulnerabilities.

EXPERTISE YOU CAN TRUST
Why Choose Chainscore for Your Privacy Audit
Our specialized audits go beyond standard security checks to protect your users' financial anonymity and data sovereignty, ensuring your wallet meets the highest standards of privacy by design.
04
Custom Privacy Threat Modeling
We build attacker models specific to your wallet's use case—from DeFi mixing to NFT ownership—to systematically identify and mitigate unique privacy threats.
05
Gas & Performance Optimization
Privacy features are computationally expensive. We optimize ZK proof generation and verification to reduce gas costs by up to 40% while maintaining security.
06
Post-Audit Implementation Support
Receive clear, actionable remediation guidance and direct access to our engineers to ensure fixes are correctly implemented before your mainnet launch.

CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from tokens to complex DeFi logic.
We architect and deploy production-ready smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking contracts, and yield strategies.
- Enterprise Logic: Multi-signature wallets, upgradeable proxies, and custom governance systems.
We don't just write code; we deliver battle-tested, mainnet-ready infrastructure with a documented security posture.
Every contract undergoes rigorous internal review using static analysis and formal verification tools before we recommend a third-party audit. We provide comprehensive documentation and a deployment package for your team, turning complex blockchain logic into a reliable asset.
