IoT Sensor Data Marketplace Backend

We build the core smart contract and indexing infrastructure for decentralized marketplaces where mobile DePIN hotspots can autonomously sell authenticated sensor data streams to buyers.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production on Ethereum, Solana, and L2s.

We architect and deploy custom, gas-optimized smart contracts that form the secure backbone of your application. Our development process is built for production from day one, ensuring reliability at scale.

  • End-to-End Development: From specification and Solidity/Rust coding to deployment and verification.
  • Security-First: All code undergoes internal audits and follows OpenZeppelin standards before third-party review.
  • Protocol Integration: Native support for ERC-20, ERC-721, SPL, and custom standards for DeFi, NFTs, and DAOs.
  • Measurable Outcomes: Achieve >99.9% uptime, 30-70% gas cost reduction, and deployment readiness in as little as 2 weeks.

02

Provable Data Integrity & Trust

Ensure sensor data is tamper-proof and verifiable. We implement cryptographic attestation (e.g., using Chainlink Functions or Pyth) and immutable data anchoring to a chosen L1/L2, creating an auditable trail for compliance and user confidence.

03

Scalable, Cost-Efficient Architecture

Handle millions of data points without exorbitant gas fees. Our architecture leverages hybrid on/off-chain design, data compression, and Layer-2 settlement (like Arbitrum, Polygon) to keep transaction costs predictable and low.

PROVEN METHODOLOGY

Our Development & Delivery Process

A structured, transparent approach designed to de-risk your IoT data marketplace build, accelerate time-to-market, and ensure enterprise-grade security from day one.

01

Discovery & Architecture Design

We begin with a deep technical workshop to define your data models, consensus requirements, and integration points. We deliver a detailed architecture blueprint covering blockchain selection (e.g., Polygon, Avalanche), data ingestion pipelines, and smart contract frameworks.

Requirement Clarity
02

Core Smart Contract Development

Our engineers build the marketplace's foundational logic: data ownership (ERC-721/1155), secure payment escrow, and verifiable data access control. Every contract is developed in Solidity 0.8+ using OpenZeppelin libraries and follows gas-optimization best practices.

Backend & Oracle Integration

We develop the off-chain backend for sensor data ingestion, storage (IPFS/Arweave), and processing. This includes secure oracle services (Chainlink) for bringing real-world data on-chain and APIs for seamless frontend connectivity.
