overview
CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built for production and scale.
Every contract is built with security-first principles, using battle-tested libraries like
OpenZeppelinand following established patterns to mitigate reentrancy and overflow risks.
- Full Development Lifecycle: Specification, implementation, unit testing (
Hardhat/Foundry), and deployment scripting. - Gas Optimization: We analyze and reduce gas costs by 15-40% for critical functions.
- Multi-Chain Ready: Code is structured for easy portability across L2s and alternative EVMs.
- Post-Deployment Support: Includes verification on block explorers and initial monitoring setup.

PROVEN PROCESS
Our Delivery Methodology
We deliver production-ready DePIN middleware through a structured, transparent process designed for technical leaders who need predictable outcomes, not just prototypes.
01
Architecture & Protocol Design
We design your messaging architecture, selecting optimal protocols (like Axelar, Wormhole, or Hyperlane) and defining data schemas for secure, low-latency hardware-to-rollup communication.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis, manual review, and formal verification for critical logic. We deliver gas-optimized code with a focus on long-term maintainability and upgradeability using patterns like ERC-2535 Diamonds.
Reduce your time-to-audit by 50% with our battle-tested development framework and comprehensive test suites.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, staking, and governance hooks. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
- Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and compliant KYC/AML integration modules.
- Full Delivery: We provide verified source code, technical documentation, and a deployment playbook for your team.

Frequently Asked Questions
Get clear answers on how our hardware-to-rollup messaging middleware works, from deployment to long-term support.
A standard integration takes 2-4 weeks from kickoff to production. This includes hardware SDK integration, rollup smart contract deployment, and end-to-end testing. Complex deployments with custom oracle logic or multi-chain support may extend to 6-8 weeks. We provide a detailed project plan in the first week.
