overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your dApp or protocol.

We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our development process is built for reliability and speed, delivering a production-ready MVP in as little as 2 weeks.

Full-Stack Expertise: From ERC-20 tokens and ERC-721 NFTs to complex DeFi logic and DAO governance.
Security-First: Built with OpenZeppelin standards and undergo rigorous internal audits before delivery.
Gas Optimization: Every contract is profiled and optimized to reduce user transaction costs by up to 40%.

We don't just write code; we deliver the foundational logic that secures your assets and powers your business model.

Our team handles the entire lifecycle:

Design & Specification: Collaborative sessions to define logic, roles, and upgrade paths.
Development & Testing: Comprehensive unit and integration tests on Hardhat or Foundry.
Deployment & Verification: Seamless deployment to your chain of choice with full source code verification.

Frequently Asked Questions

Get clear answers on timelines, costs, and technical specifics for your dedicated blockchain explorer project.

A standard deployment for a custom EVM Layer 2 explorer takes 2-4 weeks from kickoff to production. This includes core indexing, UI/UX customization, and integration with your chain's RPC. Complex requirements like custom transaction decoders, advanced analytics dashboards, or multi-chain aggregation can extend the timeline to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
