overview
CORE SERVICE

Smart Contract Development

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

We deliver audit-ready code in Solidity or Rust, deploying your core logic on-chain in 2-4 weeks. Our development includes comprehensive testing, gas optimization, and integration with your existing stack.

  • Custom Logic: Build ERC-20, ERC-721, DeFi protocols, or bespoke on-chain systems.
  • Security-First: Development follows OpenZeppelin standards and includes pre-audit reviews.
  • Full Ownership: You receive all source code, deployment scripts, and documentation.

Reduce your time-to-market and technical risk with battle-tested contract architecture.

STRATEGIC ADVANTAGES

Business Outcomes: Why a Custom DA Bridge Matters

A purpose-built ZK-Rollup Data Availability (DA) Bridge is not just infrastructure; it's a strategic asset that delivers measurable business results. Here’s what our development delivers for your project.

01

Unmatched Cost Efficiency

We architect your bridge to minimize L1 settlement costs by up to 95% compared to native L1 transactions. Our gas optimization strategies and batch processing logic directly reduce your operational overhead, protecting your margins as you scale.

ZK-Rollup DA Bridge Development: FAQs

Get clear, specific answers to the most common questions from CTOs and technical founders evaluating a custom Data Availability (DA) bridge for their ZK-rollup.

Our standard engagement follows a 4-phase process: Discovery & Architecture (1 week), Core Development (2-3 weeks), Security Audit & Testing (1-2 weeks), and Mainnet Deployment (1 week). For a typical custom ZK-Rollup DA bridge connecting to a new DA layer, the total timeline is 5-7 weeks. We provide a detailed Gantt chart at project kickoff.
