overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production by Web3-native engineers.
- Security-First Development: Code written in
Solidity 0.8+orRust, following OpenZeppelin patterns and undergoing rigorous internal audits before deployment. - Full-Spectrum Contracts: From foundational
ERC-20/721/1155tokens to complex DeFi primitives, DAO governance, and cross-chain bridges. - Battle-Tested Reliability: Contracts are deployed with comprehensive testing, gas optimization, and 99.9% mainnet uptime SLAs.
We don't just write code; we deliver the secure, auditable foundation your protocol needs to scale with confidence.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the operational backbone of your Web3 application. Our development process is built on security-first principles, utilizing formal verification and comprehensive audit trails to mitigate risk.
- Full-Stack Expertise:
Solidity/Rust/Vyperdevelopment for EVM, Solana, and Cosmos ecosystems. - Security Guarantee: Contracts are built with
OpenZeppelinstandards and undergo third-party audits before mainnet deployment. - Gas Optimization: We achieve up to 40% lower transaction costs through efficient code patterns and state management.
From tokenomics (
ERC-20,ERC-721) to complex DeFi logic, we deliver contracts that are auditable, upgradeable, and secure by design.

Frequently Asked Questions
Get clear answers on our development process, security, and timelines for building your NFT-gated identity protocol on Flow.
A standard implementation with core minting, verification, and access control features takes 3-5 weeks from kickoff to mainnet deployment. Complex integrations with existing dApps or custom on-chain logic can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the discovery phase.
