GDPR-Compliant DePIN Data Handler

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy custom smart contracts for DeFi, NFTs, DAOs, and enterprise applications. Our code is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.

Full Lifecycle Support: From initial design and development to deployment, verification, and ongoing maintenance.
Multi-Chain Ready: Deployable on Ethereum, Polygon, Arbitrum, Base, and other EVM-compatible L2s.
Security-First: All contracts undergo rigorous internal audits and are prepared for third-party review.

Reduce your time-to-market with a battle-tested development process that has delivered over 50 production contracts with zero critical vulnerabilities post-audit.

We provide comprehensive documentation and a 2-week MVP sprint for rapid validation, turning your concept into a live, auditable protocol.

ENTERPRISE-GRADE FOUNDATION

Core Architecture of Our GDPR-Compliant Handler

Our DePIN data handler is built on a modular, secure-by-design architecture that automates compliance, reduces legal risk, and accelerates your go-to-market. We deliver the technical infrastructure so you can focus on your core product.

Privacy-First Data Pipeline

End-to-end encrypted data ingestion and processing with automatic PII detection and anonymization. Built-in consent management ensures every data point is processed with a lawful basis, eliminating manual compliance overhead.

On-Chain/Off-Chain Orchestration

Intelligent routing layer that determines optimal data storage: immutable proofs on-chain (e.g., Polygon, Arbitrum) and sensitive payloads off-chain in certified EU data centers. Achieves blockchain utility without exposing personal data.

Automated Rights Fulfillment Engine

Programmatic handling of GDPR Article 15-22 rights (Access, Erasure, Portability). Automated workflows process user deletion (Right to be Forgotten) requests, propagating changes across both on-chain hashes and off-chain databases.

Cryptographic Proof of Compliance

Generates verifiable, tamper-proof attestations for every data action. Leverages zero-knowledge proofs and selective disclosure to demonstrate lawful processing to regulators without exposing underlying data, building immutable trust.

PREDICTABLE, TRANSPARENT, AND SECURE

Our 4-Phase Delivery Process

We deliver production-ready, GDPR-compliant DePIN data handlers through a structured, milestone-driven approach. Each phase includes clear deliverables, security reviews, and client sign-off to ensure alignment and mitigate risk.

Phase 1: Architecture & Compliance Design

We define the data flow architecture, map GDPR requirements (data minimization, lawful basis, DSAR handling), and select the optimal DePIN protocol (e.g., Filecoin, Arweave, or IPFS) for your use case. Deliverables include a technical specification and a Data Protection Impact Assessment (DPIA) framework.

1-2 weeks

Duration

100%

DPIA Coverage

Phase 2: Core Handler & Smart Contract Development

Development of the core data ingestion, encryption, and storage modules. We build and audit the on-chain logic for data anchoring and access control using OpenZeppelin libraries. All code follows privacy-by-design principles from the start.

3-4 weeks

Duration

Sol 0.8+

Audit Standard

Phase 3: Integration & Penetration Testing

We integrate the handler with your existing front-end/back-end and conduct rigorous security testing. This includes penetration tests on the API layer and a final smart contract audit to ensure no vulnerabilities exist before mainnet deployment.

2 weeks

Duration

OWASP Top 10

Test Coverage

Phase 4: Deployment & Compliance Handover

We deploy the system to your production environment, configure monitoring/alerting for data subject requests, and provide complete documentation. This includes a Record of Processing Activities (ROPA) and operational runbooks for your team.

For CTOs & Legal Teams

GDPR & DePIN Compliance: Key Questions

Addressing the most common technical and regulatory questions we receive from teams building compliant DePIN data infrastructure.

We implement a privacy-by-design architecture using a three-layer approach: 1) Data Minimization at the edge device level, 2) On-chain Pseudonymization using zero-knowledge proofs or hashing, and 3) Off-chain Encryption for sensitive personal data stored in our managed infrastructure. This ensures only necessary, non-identifiable data touches the public ledger, with personal data handled under strict access controls in GDPR-aligned jurisdictions.
