AppChain & Layer 3 License Verification Development

We architect and deploy dedicated application-specific blockchains (AppChains) or Layer 3 networks with license verification as a native, core function. Built for gaming, enterprise SaaS, and other verticals requiring controlled access and compliance.

overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built by Web3-native engineers.

We architect and deploy production-grade smart contracts for tokens, DeFi protocols, and NFTs. Our engineers specialize in Solidity 0.8+ and Vyper, implementing OpenZeppelin standards and custom logic with a focus on security-first development and gas efficiency.

From initial audit to mainnet deployment, we manage the full lifecycle to ensure your protocol is robust and ready for scale.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like minting, staking, and governance.
  • DeFi & DEX Logic: Automated Market Makers (AMMs), liquidity pools, yield strategies, and lending/borrowing modules.
  • Security & Audits: Multi-stage review process including unit testing, static analysis, and formal verification readiness.

Our Development & Deployment Process

A structured, security-first approach to building and launching your AppChain or Layer 3. We manage the entire lifecycle from initial design to mainnet deployment and ongoing support.

01

Architecture & Design Review

We define your chain's consensus, data availability, and interoperability model. This includes selecting the optimal L2/L3 stack (OP Stack, Arbitrum Orbit, zkSync ZK Stack) and designing for your specific throughput and cost requirements.

AppChain & License Verification FAQ

Answers to the most common questions from CTOs and founders evaluating dedicated blockchain infrastructure and compliance solutions.

From architecture to mainnet launch, a standard deployment takes 4-6 weeks. This includes 1 week for design and consensus configuration, 2-3 weeks for core development and smart contract integration, and 1-2 weeks for testing, security review, and deployment. Complex integrations with existing enterprise systems or custom consensus mechanisms can extend this to 8-10 weeks. We provide a detailed project plan with weekly milestones at kickoff.
