overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts to power your Web3 application.
- From Concept to Mainnet: Full lifecycle development, from initial design and
Solidity/Rustcoding to deployment and verification. - Security as Standard: Every contract undergoes internal audits, formal verification with tools like
Slither, and testing against common vulnerabilities. - Gas Optimization: We write efficient code to minimize transaction costs, a critical factor for user adoption and protocol sustainability.
Deliver a battle-tested, auditable foundation that reduces risk and accelerates your time-to-market.

FOUNDATION FOR TRUST
Core Attestation Infrastructure
Our battle-tested, modular infrastructure provides the cryptographic and operational backbone for verifiable, tamper-proof data from any DePIN device. We deliver the core components you need to build trust, not just manage data.
01
Secure Hardware Enclave Integration
Integrate with TPMs, HSMs, and secure elements (like Intel SGX) to cryptographically seal device identity and generate unforgeable attestations at the source. Eliminates software-level spoofing.

PROVEN PROCESS
Our Delivery Methodology
A structured, security-first approach to DePIN attestation that delivers production-ready infrastructure, not just prototypes. We focus on measurable outcomes: verifiable data integrity, reduced time-to-market, and enterprise-grade reliability.
01
Architecture & Protocol Design
We design a custom attestation architecture tailored to your device ecosystem. This includes selecting the optimal consensus mechanism (Proof-of-Location, Proof-of-Sensor, etc.), defining data schemas, and establishing cryptographic signing flows for tamper-proof data provenance.

Frequently Asked Questions
Get clear answers on how we secure and verify physical device data for your Web3 network.
We integrate a lightweight software agent onto your IoT devices or gateways. This agent collects raw sensor data (temperature, location, usage), generates a cryptographic hash, and signs it with a secure hardware key (TPM, HSM, or secure enclave). The signed attestation is then submitted on-chain via our optimized relayer. We support ARM, x86 architectures and common IoT OSes like Linux and FreeRTOS.
