We architect and deploy secure, auditable smart contracts that form the core of your Web3 application. Our development process is built on OpenZeppelin standards and follows formal verification principles to mitigate risk before deployment.
Light Client Security for Constrained Devices
Custom Smart Contract Development
Production-ready smart contracts built with enterprise-grade security and gas optimization.
- Custom Logic: Tailored
ERC-20,ERC-721,ERC-1155, and bespoke contract development. - Gas Optimization: Code-level efficiency reviews to reduce transaction costs by up to 40%.
- Security-First: Multi-stage audits, including automated analysis and manual review by our in-house experts.
- Full Lifecycle: Development, testing, deployment, and upgrade management via Transparent Proxies or Diamond Standard.
We deliver battle-tested contracts that power DeFi protocols, NFT marketplaces, and enterprise applications with 99.9% uptime SLAs.
Core Capabilities for MCU Light Clients
We deliver specialized engineering for microcontrollers, enabling secure and efficient blockchain interaction for IoT, DePIN, and embedded systems. Our solutions are built for constrained environments without compromising on security or decentralization.
Ultra-Lightweight Client Implementation
We build custom light clients for MCUs (ARM Cortex-M, RISC-V) with a memory footprint under 50KB. Our implementations support header verification and state queries for Ethereum, Polygon, and other EVM chains, enabling direct on-chain interaction from the edge.
Hardware-Secured Key Management
Integrate with hardware security modules (HSMs), TPMs, and Secure Elements (like ATECC608A) for private key generation, storage, and signing. We implement secure boot and attestation to prevent firmware tampering and key extraction.
Low-Power, Intermittent Connectivity
Optimized sync algorithms and state management for devices with limited power and unreliable networks. Our clients support checkpoint syncing and sparse Merkle proofs to minimize data transfer and CPU cycles, extending battery life.
Custom RPC & Data Feeds
We deploy and manage dedicated, geo-distributed RPC endpoints optimized for low-bandwidth devices. Includes event subscription filters and historical data pruning to deliver only the necessary blockchain data to your fleet.
Over-the-Air (OTA) Updates & Governance
Secure firmware update mechanisms with multi-sig approval and on-chain attestation. Manage and coordinate upgrades across thousands of devices via smart contract-based governance, ensuring fleet integrity and protocol agility.
Why Choose Our Light Client Security Service
We deliver purpose-built security solutions for IoT, mobile, and embedded systems, ensuring your constrained devices can participate in Web3 networks without compromising on safety or performance.
Resource-Optimized Verification
Our light client SDKs execute cryptographic verification with minimal CPU, memory, and power consumption, enabling secure blockchain interactions on devices with < 1MB RAM.
Formally Verified Core
The cryptographic and consensus logic at the heart of our clients is formally verified using tools like K-framework, providing mathematical proof of correctness against protocol specifications.
Continuous Threat Monitoring
We operate a global network of full nodes to provide real-time, authenticated fraud proofs and data availability proofs to your light clients, protecting against chain reorganizations and data withholding attacks.
Multi-Chain Protocol Support
Out-of-the-box compatibility with Ethereum (EIP-3074), Polkadot (LightSync), Cosmos (IBC), and other major L1/L2 networks. We handle protocol-specific intricacies so you don't have to.
Certified Secure Development
Our development lifecycle is ISO 27001 aligned, with all client code undergoing mandatory audits by firms like Trail of Bits and OpenZeppelin before release.
Predictable, Fixed-Cost Licensing
Simple per-device or annual enterprise licensing with no hidden fees or variable cloud costs. Includes SLA-backed support, updates, and security patches for the protocol's lifetime.

Our Development & Hardening Process
We build and harden light clients for constrained devices using a rigorous, multi-layered process designed for the unique security challenges of embedded systems and IoT.
Threat Modeling & Architecture Review
We begin with a formal threat model (STRIDE) to identify attack vectors specific to your device's hardware and network environment. This ensures security is foundational, not an afterthought.
Memory-Safe Implementation
We develop core logic in Rust or C with MISRA-C guidelines to eliminate buffer overflows and memory corruption—critical for devices with no memory protection units (MPUs).
Cryptographic Hardening
We implement and audit all cryptographic operations (signatures, hashing, key derivation) for side-channel resistance and constant-time execution on low-power MCUs.
Hardware Security Module (HSM) Integration
We integrate with secure elements (ATECC608, SE050) or TEEs (TrustZone) for key storage and secure boot, ensuring private keys never leave the protected enclave.
Final Security Audit & Certification Prep
Every client undergoes a final review by our internal security team and is prepared for third-party audits (like NCC Group) or relevant certifications (PSA Certified, SESIP).
Light Client Security for IoT: FAQs
Get answers to the most common technical and commercial questions about securing blockchain connectivity for your constrained IoT devices.
Standard deployments take 4-6 weeks from kickoff to production-ready firmware. This includes a 2-week architecture and cryptographic design phase, 2-3 weeks of implementation and integration, and 1 week for final security validation and device testing. Complex integrations with custom hardware security modules (HSMs) may extend this by 1-2 weeks.
