01. Smart Contracts

We offer smart contract development services optimized for the latest blockchain ecosystems.

Our team supports a wide range of networks, including Ethereum (EVM), Solana (SVM), Move VM, and Cosmos.

We handle the full lifecycle of smart contract development—from design and coding to testing and deployment—using languages such as Solidity, Rust, Move, and AssemblyScript.

We ensure compatibility with global token and NFT standards (ERC-20, ERC-721, ERC-1155, ERC-404), and develop contract

02. Web2 / Web3 Integration

We provide seamless integration of blockchain functionality into existing web services.

By leveraging backend frameworks like NestJS, ExpressJS, Django, and FastAPI, alongside frontend technologies such as React, Vue, Next.js, Astro, and Svelte, we bridge Web2 and Web3 environments.

Our team develops cross-platform applications using React Native, Expo, Flutter, Electron, Cordova, and Blazor—implementing advanced Web3 features such as wallet integration, token and NFT handling, and on/off-chain data synchronization via libraries like Ethers.js, Viem, Wagmi, and RainbowKit.

We also offer REST/GraphQL APIs and blockchain-specific SDKs to support scalable Web3 infrastructure.

03. Infrastructure / Network

We build reliable and scalable blockchain infrastructure tailored to your needs.

Our services include node deployment and operation for major networks such as Ethereum and Solana, covering public, private, and multi-chain environments.

We implement sharding, cloud integration (AWS, GCP, Azure), automated monitoring systems, and scalability solutions.

Additional capabilities include blockchain data indexing (Indexer), developer tooling, traffic optimization, global expansion support, and incident response and recovery.

04. Development Support / Consulting

We provide end-to-end support for your blockchain project.

Our services include comprehensive resources such as official SDKs for each network, REST/GraphQL APIs, detailed documentation, tutorials, code samples, and developer guides.

We provide tailored consulting across all stages—from architecture design, technical validation (PoC), and MVP development to go-to-market strategy, global expansion, and regulatory compliance.

In addition, we actively contribute to ecosystem growth through code reviews, developer education, community engagement, and the adoption of the latest frameworks.

05. Security / Standards

We ensure the highest level of security and compliance with international standards.

Our comprehensive security framework includes smart contract audits, vulnerability assessments, third-party audit support, and adherence to standards such as EIP, ERC-20/721/1155/404, and ISO/TC 307.

We build a secure and trustworthy blockchain environment by employing secure communication protocols such as JSON-RPC and ABI, ensuring data integrity through distributed ledgers, strengthening network security, conducting threat modeling (e.g., STRIDE and Attack Tree), performing risk assessment and response, and offering security education programs for both users and developers.
