We are delighted to announce our support for Japan Open Chain, where network participants can now take advantage of SubQuery’s leading data indexer.

Japan Open Chain (JOC) is an Ethereum-compatible Layer 1 Public Blockchain operated by Japanese companies and ideal for business use. 

Developers building on Japan Open Chain can now harness SubQuery's versatile, high-speed, open, and decentralised data indexing solution. This empowers blockchain developers with crucial tools to efficiently manage and query on-chain data for their protocols and applications.

By providing developers with a tailor-made API, SubQuery simplifies backend operations. In this way, they can focus on developing their products and enhancing their user experiences without having to allocate resources toward constructing their indexing solutions.

"Incorporating SubQuery into our platform accelerates data access for developers on Japan Open Chain, streamlining their experience within our growing ecosystem. This empowers them to build more dynamic projects more easily and accurately on a public chain operated by a leading company.”

— Hidekazu Kondo, Founder, Japan Open Chain 

We’re always striving to provide developers with the most comprehensive and efficient indexing experience possible, including the open-source SDK, tools, documentation, and developer support that the SubQuery ecosystem provides. Japan Open Chain is also supported in SubQuery’s enterprise level managed service, which provides enterprise-level infrastructure hosting and handles hundreds of millions of requests each day. 

“Excited to announce our integration support with Japan Open Chain. Our indexing service provides advanced tools, empowering their community to innovate and drive Web3 adoption in Japan."

— Sam Zou, Founder and CEO of SubQuery

Why Use SubQuery?

SubQuery makes it easy to build a custom API for your dApp or smart contracts in minutes, providing clean indexed data to any service. The excellent SubQuery developer experience is flexible, with the ability to make external API calls or import external libraries from within your mapping functions, and better controls to run your projects in your own infrastructure with automated DOS (denial of service) mitigation controls. Additionally, we have yet to make plans to sunset our managed service.

SubQuery is designed to be fast. This adds up when you’re indexing millions of ledgers, and is something to consider when choosing your indexer. SubQuery achieves this by using multi-threading and optimisation of the store to reduce costly database writes. With faster sync times, developers can iterate faster and deliver features to market quicker.
