AppChain & Layer 3 DePIN Development

overview

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for speed and reliability.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our contracts are built with OpenZeppelin standards, undergo rigorous security audits, and are optimized for gas efficiency and upgradability.

From token launches to complex DeFi protocols, we deliver battle-tested code that just works.

Token Systems: ERC-20, ERC-721, SPL tokens with custom minting, vesting, and staking logic.
DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, yield aggregators, and lending protocols.
Utility & Governance: Multi-signature wallets, DAO frameworks, and access control systems.
Delivery: Full audit trail, comprehensive documentation, and deployment support on mainnet.

ARCHITECTURAL ADVANTAGES

Why Build a Dedicated Chain for Your DePIN

A purpose-built blockchain provides the performance, control, and economic alignment required for DePINs to scale. Generic Layer 1s and 2s introduce bottlenecks that dedicated infrastructure eliminates.

Tailored Consensus & Performance

Design a consensus mechanism optimized for your physical hardware network. Achieve sub-second block times and deterministic finality for sensor data, IoT commands, and microtransactions.

Sovereign Economic Policy

Define your own gas token, fee market, and inflationary/deflationary model. Align network incentives directly with hardware participation and resource provisioning without external token volatility.
