overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts for your token, DeFi, or NFT project.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on audit-ready code, OpenZeppelin standards, and gas optimization to ensure reliability and cost-efficiency from day one.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance logic.
  • DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending vaults.
  • Enterprise Logic: Multi-signature wallets, access control, upgradeable proxy patterns, and cross-chain bridges.

We deliver a fully audited, deployable contract suite in 2-4 weeks, complete with comprehensive documentation and a security review report.

A STRUCTURED APPROACH

Our Development & Integration Process

We deliver production-ready ZK & Optimistic Rollup Router Architectures through a transparent, milestone-driven process. This ensures predictable timelines, clear deliverables, and a seamless handover for your engineering team.

01

Architecture & Design Review

We analyze your L1/L2 ecosystem and business logic to design a custom router architecture. This includes selecting the optimal rollup type (ZK vs. Optimistic), defining cross-chain messaging patterns, and establishing security parameters.

2-3 days
Initial Design
1 week

Frequently Asked Questions

Get clear answers on our development process, timelines, and technical approach for building secure, scalable cross-rollup infrastructure.

A production-ready ZK or Optimistic rollup router with core bridging and messaging functions typically deploys in 4-8 weeks. This includes architecture design, smart contract development, integration with 2-3 target rollups (e.g., Arbitrum, zkSync, Optimism), and initial security review. Complex features like generalized message passing or custom fraud proofs can extend the timeline. We provide a detailed project plan with milestones in the first week.
