About Us
A team of blockchain engineers, cryptographers, and product builders
Our Story
NEXT AI was founded in 2021 by a team of engineers who met at the Ethereum Foundation. We saw the gap between cutting-edge blockchain research and production-ready software, and set out to bridge it. Since then, we've shipped 50+ projects across 15 blockchain protocols, earning a reputation for security-first engineering and relentless quality.
Our Approach
We believe blockchain software demands a higher standard. Immutable code must be correct the first time, so we pair test-driven development with formal verification, fuzz testing, and multiple independent audits. Every project gets a dedicated security lead from day one. We don't just write code; we protect value.

Frequently Asked Questions
Straight answers about scope, timelines, security and pricing.
What development services does NEXT AI offer?
End-to-end delivery across blockchain (smart contracts, dApps, DeFi, NFTs, audits, consulting), AI (LLM/Agent/RAG), cross-border e-commerce, chat software (IM/E2EE) and anime & games (Unity/Cocos + GameFi).
Which blockchains and L2s do you support?
15+ production chains including Ethereum, Solana, Polygon, BNB Chain, Arbitrum, Optimism, Base, Avalanche, TON, Aptos, Sui and Cosmos SDK networks.
How long does a typical project take?
MVPs usually ship in 4-6 weeks and production releases in 8-16 weeks. We work in two-week agile sprints with a runnable demo and code hand-off at every milestone.
Do you support private LLM deployment?
Yes. We fine-tune and self-host open models such as Llama, Qwen and DeepSeek on customer VPCs, wire them into RAG knowledge bases and Agent workflows, and meet data-residency requirements.
What does the cross-border e-commerce stack cover?
Standalone and multi-store systems with 12+ languages, 8+ fiat currencies and USDC/USDT settlement, integrated with Stripe, PayPal, Alipay International, logistics, customs, tax and regional compliance.
How do you keep chat software secure and fast?
End-to-end encryption via the Signal Protocol, optional wallet login (SIWE), and a distributed messaging gateway achieving <150ms P99 latency with millions of concurrent users and A/V calls.
Can anime and game titles include on-chain assets?
Yes. Unity / Unreal / Cocos clients paired with ERC-721/1155 or Solana NFT standards enable on-chain ownership of characters, items and skins with secondary trading and full GameFi tokenomics.
