IoT Device Identity & Payment Authentication

Implement a secure, blockchain-based identity layer for IoT devices to authenticate payments and service access. We build systems using DIDs and verifiable credentials to prevent fraud and enable permissioned micropayments.

SECURE FOUNDATIONS

Custom Smart Contract Development

Production-ready smart contracts built with security-first development and comprehensive audit support.

We architect and deploy secure, gas-optimized smart contracts for tokens, DeFi protocols, and NFT ecosystems. Our development process is built on OpenZeppelin standards and includes formal verification for critical logic.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 with minting, vesting, and governance modules.
  • DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, and staking contracts with <1% gas cost optimizations.
  • Security First: Every contract undergoes manual review and automated analysis with Slither and MythX before audit.

We deliver fully documented, auditable code with a 99.9% uptime SLA for mainnet deployments, ensuring your protocol's foundation is unshakable.

Our Implementation Process

A structured, four-phase engagement designed for technical leaders who need secure, production-ready IoT identity solutions without the typical delays and security debt.

01

Architecture & Protocol Design

We define your device identity model (ERC-6551, ERC-725, or custom), payment flow architecture, and select the optimal L2 (Polygon, Arbitrum) or appchain for your throughput and cost requirements.

Frequently Asked Questions

Get clear answers on our process, security, and timelines for implementing blockchain-based identity and payment solutions for IoT devices.

We implement a multi-layered security architecture. Each device receives a unique, non-transferable on-chain identity (typically an NFT or SBT) anchored to its hardware root of trust. Private keys are generated and stored in secure enclaves (like TPM or HSM modules). All authentication logic is executed via audited smart contracts on EVM-compatible chains, ensuring tamper-proof verification. Our standard deployment includes a comprehensive security audit by a third-party firm.
