overview
SECURE FOUNDATION

Custom Smart Contract Development

Production-ready smart contracts built with enterprise-grade security and gas optimization.

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.

  • 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.

SECURITY-FIRST METHODOLOGY

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.

01

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.

STRIDE

OWASP
IoT Top 10
02

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.

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.
