Application-Specific Layer 3 Development

We build dedicated Layer 3 blockchains that settle to Layer 2s, giving your enterprise full control over application logic, transaction fees, and governance while abstracting base-layer complexity.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy battle-tested smart contracts that form the immutable foundation of your application. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

  • Custom Logic: Build on ERC-20, ERC-721, ERC-1155 or bespoke standards.
  • Security Patterns: Implement OpenZeppelin libraries and formal verification practices.
  • Deployment & Management: Full lifecycle support from testnet to mainnet with upgradeability strategies.

Reduce your time-to-market and technical risk with contracts built for scale.

Our engineers deliver modular, well-documented code in Solidity 0.8+ or Rust (for Solana). We focus on audit-friendly development, producing code that passes scrutiny from firms like CertiK and Quantstamp. Get a production-ready MVP in 2-4 weeks.

PROVEN METHODOLOGY

Our Layer 3 Development Process

A structured, four-phase approach designed to deliver production-ready, high-performance L3s with minimal technical debt and maximum security.

01

Architecture & Design

We define your L3's core architecture, including the optimal rollup framework (OP Stack, Arbitrum Orbit, zkSync ZK Stack) and data availability layer. This phase establishes the technical foundation for scalability and cost-efficiency.

2-3 weeks

Frequently Asked Questions

Get clear answers on timelines, costs, and technical details for your custom Layer 3 blockchain project.

A standard L3 deployment with a custom data availability layer and a single rollup sequencer takes 4-6 weeks from kickoff to mainnet. For a fully managed, multi-sequencer, high-throughput system with custom precompiles, the timeline extends to 8-12 weeks. We provide a detailed project plan within the first week of engagement.
