CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or dApp.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with vesting, minting, and governance logic. - DeFi Primitives: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending protocols.
- Custom Logic: Multi-signature wallets, DAO governance modules, and bespoke on-chain business rules.
- Full Lifecycle: From architecture and development to testing, deployment, and post-launch maintenance.
We deliver contracts that pass security audits on the first review, reducing your time-to-market by weeks and mitigating critical financial risk.
Our engineers have deployed over 200+ contracts across EVM chains like Ethereum, Polygon, and Arbitrum. We provide comprehensive documentation and a verified deployment package for seamless handoff to your team.

Sidechain Development FAQs
Get clear, direct answers to the most common questions CTOs and founders ask when evaluating a sidechain development partner.
A standard EVM-compatible sidechain with a custom bridge is typically deployed in 2-4 weeks from kickoff. Complex deployments with custom consensus, advanced tokenomics, or multi-chain interoperability can take 6-8 weeks. We provide a detailed project plan with weekly milestones during scoping.
