Building Blockchain Solutions Since 2017
Our Tokyo-based team combines deep technical knowledge with practical blockchain development experience to deliver secure, scalable Web3 solutions.
Return HomeOur Story
Chain Logic was established in Tokyo in 2017 when blockchain technology was transitioning from experimental concept to practical business tool. Our founders recognized the potential for decentralized systems to transform how organizations operate, but also understood the critical need for security, reliability, and professional development standards.
Starting with smart contract development for early Ethereum projects, we quickly became known for our rigorous security auditing and gas optimization techniques. As the blockchain ecosystem expanded, we evolved our expertise to encompass DeFi protocols, NFT platforms, and cross-chain solutions. Each project taught us valuable lessons about the importance of thorough testing, clear documentation, and sustainable architecture.
Today, Chain Logic serves clients across Japan and internationally, having deployed over 50 smart contracts securing more than ¥2.5 billion in total value. Our team has grown from three developers to a comprehensive blockchain development studio, but our core commitment remains unchanged: delivering secure, efficient, and well-documented Web3 solutions that meet real business needs.
We maintain our position at the forefront of blockchain development by continuously studying emerging technologies, participating in developer communities, and contributing to open-source projects. Our office in Tokyo's Nishi-Azabu district serves as both our development headquarters and a meeting space for the local Web3 community.
Our Methodology
Security-First Development
Every smart contract we develop undergoes comprehensive security analysis before deployment. Our process includes static analysis, dynamic testing, formal verification where applicable, and manual code review by multiple team members. We actively search for common vulnerabilities including reentrancy attacks, integer overflow, access control issues, and front-running susceptibilities. This rigorous approach has maintained our record of zero security incidents across all deployed contracts.
Comprehensive Testing Framework
We implement multi-layered testing that covers unit tests for individual functions, integration tests for contract interactions, and scenario tests simulating real-world usage patterns. Our test coverage targets exceed 95% for all production code. We use both automated testing frameworks and manual testing procedures to identify edge cases and potential issues. Economic modeling and stress testing help ensure protocol stability under various market conditions.
Gas Optimization Standards
Transaction costs significantly impact user experience and project viability. We apply systematic gas optimization techniques including efficient data structures, optimized storage patterns, batching operations where appropriate, and leveraging assembly for performance-critical sections. Our optimization process reduces gas costs while maintaining code readability and security. We provide detailed gas consumption reports and recommendations for ongoing cost management.
Documentation and Knowledge Transfer
Clear documentation ensures project maintainability and enables effective collaboration. We provide comprehensive technical documentation covering architecture decisions, contract interactions, deployment procedures, and upgrade strategies. All code includes detailed comments explaining logic and potential considerations. We offer training sessions to help your team understand and maintain the delivered solutions. Our documentation follows industry standards and includes diagrams, flowcharts, and example usage scenarios.
