ESG Data On-Chain Verification Service

We build secure, auditable systems that collect, verify, and immutably store Environmental, Social, and Governance (ESG) metrics on-chain, linking them directly to tokenized assets for transparent, fraud-resistant impact reporting.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by experts for your Web3 product.

We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our development process is built for speed and reliability, delivering a minimum viable product (MVP) in 2-4 weeks.

  • Full-Spectrum Development: From ERC-20 tokens and ERC-721 NFTs to complex DeFi protocols and DAO governance systems.
  • Security-First Approach: Every contract undergoes rigorous audits using static analysis, formal verification, and manual review based on OpenZeppelin standards.
  • Gas Optimization: We reduce your users' transaction costs by 15-40% through efficient code patterns and storage strategies.

We don't just write code; we deliver the foundational logic your business runs on, with 99.9% reliability and zero critical vulnerabilities at launch.

Our team handles the entire lifecycle:

  • Design & Specification: Collaborative workshops to define logic, roles, and upgrade paths.
  • Development & Testing: Implementation in Solidity 0.8+ or Rust (for Solana), with comprehensive unit and integration tests.
  • Deployment & Verification: Mainnet deployment, Etherscan verification, and provisioning of frontend ABIs.

A PROVEN METHODOLOGY

Our Development & Integration Process

From initial audit to production launch, our structured 4-phase process ensures your ESG data achieves verifiable, tamper-proof integrity on-chain with minimal operational disruption.

01

Phase 1: ESG Data Audit & Schema Design

We analyze your existing ESG data sources and KPIs to design a custom, auditable data schema. This includes defining the on-chain data structure, attestation logic, and mapping to standards like GRI or SASB.

Deliverable: A finalized technical specification document and smart contract architecture.

Phase 2: Smart Contract Development & Security

Our team builds the core verification logic using Solidity 0.8+ and OpenZeppelin libraries. We implement data attestation, multi-signature approval workflows, and immutable audit trails.

Deliverable: Production-ready, gas-optimized smart contracts with comprehensive unit tests.

Phase 3: Oracle Integration & Data Pipeline

We securely connect your off-chain ESG data sources (APIs, IoT, reports) to the blockchain via a custom, high-availability oracle service. This ensures reliable, automated data feeds for on-chain verification.

Deliverable: A deployed, monitored oracle node with failover mechanisms.

Phase 4: Frontend SDK & API Integration

We provide a lightweight SDK and RESTful APIs for your team to easily query verified ESG data, generate compliance reports, and embed verification badges directly into your applications.

Deliverable: Integration-ready SDK with documentation and example implementations.

CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic and audited for enterprise deployment.

We architect and deploy custom Solidity or Rust smart contracts that form the immutable backbone of your application. Our development process is built on OpenZeppelin standards and includes comprehensive unit and integration testing before any line of code is audited.

We don't just write contracts; we engineer systems with security and gas efficiency as first principles, reducing your operational risk and long-term costs.

  • From Specification to Mainnet: We handle the full lifecycle—requirements, development, testing, and deployment—delivering a production-ready MVP in as little as 3 weeks.
  • Security-First Development: Every contract undergoes internal review against common vulnerabilities (reentrancy, overflow) before proceeding to formal audit with our partner firms.
  • Protocol-Specific Logic: Expertise in ERC-20, ERC-721, staking mechanisms, multi-signature wallets, and custom DeFi primitives tailored to your tokenomics.

ESG On-Chain Verification: Key Questions

Get clear answers on how we deliver verifiable, tamper-proof ESG data infrastructure for enterprises and protocols.

A standard ESG data verification pipeline deployment takes 3-5 weeks from kickoff to mainnet launch. This includes 1 week for requirements & data source mapping, 2 weeks for core smart contract & oracle development, and 1-2 weeks for integration testing and security review. Complex multi-chain or custom metric projects may extend to 8 weeks.
