Products & Services

Our product is a continuation of our previous product Sorobook (version 1). Sorobook is an indexer with an integrated API server that collects Soroban transaction data and event data to provide feature-rich queries to Dapps in a clean, user-friendly format, along with sufficient documentation. Given what we have to offer, many Dapps could utilize our product to greatly enhance their UI/UX in terms of performance and utility. With that being said, there is still plenty of room to improve, most notably to support contract state and contract calls data. Though it's what is needed by most Dapps, existing API solutions don't have it as it is complicated to implement (requires complex data processing and efficient data management). That's why we want to introduce the next version of Sorobook so that we can include these needed functionalities.

Sorobook ver2.0 would support these types of data. We opt to provide friendly JSON data so that Dapps UI can easily work with our APIs. For that purpose, we've developed a JSON-XDR two-way converter in Golang. Once the development work is done, we'll host public APIs available for everyone to use. In the future, as our user base grows, we plan to provide a more robust hosting infrastructure, along with a tiered subscription service based on usage and load.

Our product integrates seamlessly with Stellar. All we have to do is run a Stellar core instance, which is where we fetch our data using the Go ingest library. The collected data is then processed and pushed into a PostgreSQL database, which is in turn used by our API server.
