GDPR Data Erasure Execution Layer

overview

CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built by Web3-native engineers.

We architect and deploy production-grade smart contracts that power your core business logic. Our development process ensures security-first design, gas efficiency, and upgradeability from day one.

Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with advanced features like vesting, staking, and governance.
DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, yield aggregators, and derivative contracts.
Enterprise Logic: Multi-signature wallets, access control systems, and custom business logic for on-chain operations.

We deliver fully audited, battle-tested code with a 99.9% uptime SLA for mainnet deployments.

Our engineers write in Solidity 0.8+ and Vyper, leveraging established patterns from OpenZeppelin and our own proprietary security libraries. Every contract undergoes rigorous unit and integration testing before peer review.

Typical Deliverables & Timeline:

Week 1-2: Architecture design, specification, and initial implementation.
Week 3-4: Internal audit, testing suite completion, and staging deployment.
Week 5: External audit coordination and final mainnet deployment.

We provide comprehensive documentation and post-launch support to ensure your contracts operate flawlessly.

TECHNICAL FOUNDATION

Core Protocol Capabilities

Our execution layer is engineered for legal compliance and operational reliability. We deliver a verifiable, tamper-proof system for managing the complete data lifecycle under GDPR Article 17.

Immutable Erasure Ledger

Every data erasure request and its execution is recorded on a permissioned blockchain, creating an immutable, court-admissible audit trail. This provides definitive proof of compliance for regulators.

100%

Immutable Proof

Sub-Second

Record Finality

Multi-Protocol Data Locator

Intelligently maps and discovers user data across SQL/NoSQL databases, data lakes (S3, GCS), and SaaS APIs using a unified schema. Eliminates manual discovery, reducing compliance risk.

GUARANTEED COMPLIANCE

Business Outcomes for DePIN Operators

Our GDPR Data Erasure Execution Layer transforms a complex legal requirement into a reliable, automated technical process. DePIN operators gain a verifiable compliance advantage, reducing legal risk and building user trust.

Automated Erasure Request Fulfillment

We implement on-chain workflows that automatically execute GDPR Article 17 "right to erasure" requests. Our system processes requests, verifies user identity, and triggers data deletion across your DePIN nodes without manual intervention.

PROVEN FRAMEWORK

Our Delivery Methodology

A systematic, security-first approach to building your GDPR-compliant data erasure layer, ensuring legal certainty and technical robustness from day one.

Compliance & Architecture Design

We begin with a deep-dive audit of your data flows to architect a privacy-by-design execution layer. This phase defines the on-chain proof structure, data minimization strategies, and smart contract logic that enforces GDPR Article 17 rights.
