DePIN Confidential Payment Gateway

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that form the foundation of your Web3 application. Our development process ensures security, gas efficiency, and upgradability from day one.

Full Lifecycle Support: From initial concept and Solidity/Rust development to deployment and ongoing maintenance.
Security-First: Code follows OpenZeppelin standards and undergoes rigorous internal audits before any third-party review.
Protocol-Specific: Expertise in ERC-20, ERC-721, ERC-1155, and custom standards for DeFi, NFTs, and DAOs.

We deliver battle-tested contracts that power real user transactions, not just proof-of-concepts.

Our engineers focus on real-world outcomes: reducing gas costs by up to 40%, enabling seamless upgrades via proxy patterns, and ensuring compliance with the latest EIPs. You get a production-ready codebase in as little as 2-4 weeks for an MVP, backed by comprehensive documentation.

ARCHITECTURE & SECURITY

Core Technical Capabilities

Our DePIN Confidential Payment Gateway is engineered for enterprise-grade reliability and security, delivering the robust infrastructure needed to scale your physical network with financial services.

Zero-Knowledge Proof Integration

Implement privacy-preserving transactions using ZK-SNARKs/STARKs to validate payments without exposing sensitive user data or transaction details on-chain. Enables compliant DePIN models in regulated markets.

Multi-Chain Settlement Layer

Deploy a gateway that aggregates and settles payments across Ethereum, Solana, and Polygon. Reduces gas costs by 40-60% and ensures transaction finality aligned with your DePIN's operational regions.

Real-Time Oracle Feeds

Secure, low-latency data oracles for off-chain asset pricing and IoT sensor verification. Built with redundancy and cryptographic attestations to prevent manipulation and ensure payment accuracy.

Automated Compliance Engine

Modular compliance modules for KYC/AML checks, transaction monitoring, and regulatory reporting. Enables programmable rule-sets for different jurisdictions without compromising user privacy.

High-Availability Infrastructure

Fault-tolerant gateway deployment with geo-distributed nodes, automated failover, and 24/7 monitoring. Guarantees payment processing continuity critical for physical network operations.

Custom Smart Contract Suite

Tailored payment escrow, reward distribution, and staking contracts built with OpenZeppelin standards. Includes formal verification and third-party audit readiness for security assurance.
