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.
AppChain & Layer 3 License Verification Development
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
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, andERC-1155contracts 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.
Core Technical Capabilities We Deliver
We architect and deploy the complete technical stack for your AppChain or Layer 3, from the foundational consensus to the user-facing verification portal. Our focus is on delivering production-ready, secure, and scalable systems.
Verifier Node Infrastructure
Provisioning and management of the validator/sequencer nodes that power your chain. We ensure high availability, geographic distribution, and DDoS protection with a 99.9% uptime SLA for core services.
End-User Verification Portal & APIs
Development of a white-label dApp or set of REST/GraphQL APIs that allow end-users and partners to verify licenses in real-time. Includes wallet integration, proof generation, and audit logging.
Business Outcomes for Your Vertical
Our AppChain and Layer 3 license verification development delivers concrete, measurable results. We build infrastructure that directly impacts your bottom line, security posture, and time-to-market.
Regulatory Compliance & Audit Trail
Immutable, on-chain verification logs for licenses, KYC/AML checks, and regulatory reporting. Automate compliance workflows and provide regulators with transparent, tamper-proof audit trails, reducing manual overhead and compliance risk.
Reduced Fraud & Operational Cost
Eliminate manual license checks and counterfeit credential verification. Our automated on-chain systems reduce fraud-related losses and cut operational verification costs by automating processes that traditionally require significant manual intervention.
Faster Time-to-Market for Partners
Provide APIs and SDKs for partners to instantly verify licenses on-chain. Accelerate ecosystem growth by enabling third-party developers and businesses to integrate verified credential checks in days, not months.
Enhanced User Trust & Experience
Build user confidence with verifiable, portable credentials. Users own and control their verified licenses, enabling seamless, trustless interactions across your platform and the broader Web3 ecosystem without repetitive KYC.
Scalable, Future-Proof Architecture
Deploy on dedicated AppChains or Layer 3s for high throughput and low-cost transactions. Our architecture scales with your user base, ensuring sub-second verification times and predictable gas costs, isolated from mainnet congestion.

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.
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.
Smart Contract & Node Development
Development of core system contracts (bridge, sequencer, validator management) and deployment of your custom execution and consensus nodes. We implement gas-efficient contracts using Solidity 0.8+ and OpenZeppelin libraries.
Security Audit & Penetration Testing
Comprehensive security review by our in-house auditors, followed by a formal audit with a top-tier third-party firm (e.g., Trail of Bits, Quantstamp). We conduct penetration tests on the node infrastructure and bridge components.
Testnet Deployment & Staging
Full deployment to a public testnet (Sepolia, Holesky) with monitoring, explorer integration, and faucet setup. We run load tests simulating 10k+ TPS and coordinate with ecosystem partners for bridge and indexer integrations.
Mainnet Launch & Go-Live
Managed mainnet deployment with multi-sig governance for contract upgrades. We provide 24/7 SRE support for the first 72 hours, ensuring sequencer health, bridge liquidity, and real-time incident response.
Ongoing Maintenance & Upgrades
Proactive monitoring, node health management, and scheduled protocol upgrades. We offer SLAs for uptime (99.9%) and provide regular performance reports and optimization recommendations.
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.
