We are delighted to announce our support for Stellar and Stellar’s new Soroban smart contract network, where network participants can now take advantage of SubQuery's leading data indexer.

Stellar is a decentralized, public blockchain that gives developers the tools to create experiences that are more like cash than crypto. The network is faster, cheaper, and far more energy-efficient than most blockchain-based systems. Soroban is the new developer-friendly, Rust-based smart contract platform built on Stellar that will allow smart contracts to access Stellar’s wide variety of on-chain assets and worldwide on and off-ramps.

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. Stellar 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. 

SubQuery will also support Stellar developers with another decentralised indexing alternative with the impending launch of the SubQuery Network. The SubQuery Network will index and service data from projects to the global community in an incentivized and verifiable way and support indexing Stellar projects, and those from any other supported network from the outset.

"With SubQuery's intricate indexing fueling the Stellar ecosystem, developers can now benefit from SubQuery's fast, flexible, and open indexing solution. We are confident that our support of Stellar will help encourage web3 builders to create the next wave of exciting decentralised applications.”

— Marta Adamczyk, Technology Evangelist at 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 no 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 mulit-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.

Getting Started with SubQuery and Stellar

The best way is to start by following our step-by-step guide using a real-world example project. Follow our quick start tutorial to learn all the features of our Stellar indexer, through an example that indexes all Soroban transfer events, and account payments including credits and debits on Stellar's Futurenet.

We’ve updated the SubQuery Documentation to add Stellar specific information to the general SubQuery documentation.

SubQuery’s Support for Stellar

About Stellar

Stellar is an open-source and decentralized global exchange network that allows digital currency to fiat money low-cost transfers. It also allows cross-border financial transactions among any pair of currencies. 

Stellar allows users to trade money or tokens with the help of the Stellar Consensus Protocol. This decentralized and distributed network connects interconnected servers (nodes) within the Stellar network. Anyone can create a Stellar core verification node by using the Stellar core, which is the backbone of the Stellar network. It is responsible for verifying transactions using the Stellar consensus protocol, the algorithm that verifies transactions on the Stellar network. The Stellar core is run by trusted nodes, known as verification nodes, that verify transactions.

About SubQuery

SubQuery is a leading blockchain data indexer that provides developers with fast, flexible, universal, and decentralised APIs for web3 projects. We empower developers from over 100+ ecosystems including Stellar, Ethereum, Polygon, Polkadot, Cosmos, Algorand, NEAR, and Avalanche with rich indexed data to allow them to build intuitive and immersive decentralised applications. This blockchain developer toolkit enables developers to focus on their core use case and front-end without wasting time building a custom backend for data processing activities. In the near future, the SubQuery Network will replicate this scalable and reliable solution in a completely decentralised manner.
