overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists to power your dApp.

We architect and deploy custom smart contracts on EVM and Solana that are gas-optimized and security-audit ready. Our development process integrates formal verification and industry-standard testing frameworks to ensure reliability from day one.

  • Token Standards: ERC-20, ERC-721, ERC-1155, and SPL token implementations.
  • DeFi Protocols: Custom DEXs, lending/borrowing pools, staking, and yield aggregators.
  • Utility Contracts: Multi-signature wallets, vesting schedules, DAO governance modules, and access control systems.
  • Security First: All code follows OpenZeppelin best practices and undergoes rigorous internal review before external audit.

We deliver fully documented, deployable contracts in 2-4 weeks, reducing your time-to-market and technical risk.

Core Capabilities of Our Confidential NFT Contracts

Our confidential NFT minting contracts are engineered for high-value assets, combining zero-knowledge privacy with the full functionality of public NFTs. We deliver production-ready, audited code that protects sensitive metadata and ownership details without sacrificing interoperability.

02

Selective Disclosure & Proofs

Enable owners to generate verifiable proofs of specific attributes (like authenticity or membership tier) without revealing the underlying data. Essential for KYC/AML compliance, gated experiences, and trustless verification in DeFi.

04

Gas-Optimized Confidential Minting

Our proprietary circuit designs and contract logic reduce the gas cost of private minting and transfers by up to 40% compared to baseline implementations, making confidential NFTs viable for large-scale collections.

06

Enterprise Integration SDK

Accelerate development with our TypeScript/Go SDKs for backend integration. Includes APIs for key management, proof generation, and seamless wallet connectivity (MetaMask, WalletConnect) for your frontend.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our contracts are built for real-world use cases like DeFi protocols, NFT marketplaces, and enterprise tokenization.

  • Security-First Development: Code written in Solidity 0.8+ or Rust, following OpenZeppelin standards and undergoing rigorous internal audits before deployment.
  • Gas Optimization: We minimize transaction costs by 30-50% through efficient logic and storage patterns.
  • Full Lifecycle Support: From initial design and Hardhat/Foundry testing to mainnet deployment and upgrade management via proxies.

Deliver a secure, auditable, and high-performance contract suite in as little as 2-4 weeks for an MVP.

Frequently Asked Questions

Get clear answers on our process, security, and deliverables for building private NFT minting contracts.

Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes 1 week for requirements and architecture, 1-2 weeks for core development and internal testing, and 1 week for client review, final testing, and deployment. Complex integrations (e.g., custom zk-circuits, multi-chain) can extend this to 6-8 weeks. We provide a detailed sprint plan at project start.
