Our Solana Indexer is now open-sourced and is accessible publicly. Feel free to access it on Luganodes’ GitHub.


Indexers in the Web3 space are like the gears in a well-oiled machine, vital for the smooth and efficient functioning of blockchain technology. They work behind the scenes, meticulously organizing and simplifying the vast and complex data on blockchains. This is crucial in many applications including decentralized applications (dApps), which rely on quick and efficient data access to provide seamless experiences to their users. Indexers essentially transform the raw, often chaotic blockchain data into a structured format, making it easily accessible and usable.

Open-source technology is pivotal in Web3 development. Embracing these principles, particularly for tools like indexers, promotes collective growth and innovation. This strategy not only propels development forward but also resonates with the decentralization ethos central to Web3, aiming to create an inclusive, transparent, and community-focused technological future.

As we make our Solana indexer open-source, we're tapping into this collaborative spirit, inviting a global community to join us in refining and evolving our tools for a decentralized world.

What are Indexers?

Blockchain transactions are distinctive since they are an immutable trace on the ledger. Each action, whether it's a smart contract execution, transfer of digital currency, or any other blockchain interaction, is permanently recorded. This record is time-stamped and linked to previous transactions, forming a continuous chain. Due to this transparency and permanence, blockchain transactions are highly secure and verifiable, with every action being traceable and irreversible once recorded.

However, despite the straightforward nature of recording transactions on a blockchain, creating a database from this information for querying is not as simple. The complexity arises from the decentralized and encrypted nature of blockchains. Each block contains a multitude of transaction details encoded in a way that ensures security and privacy. Therefore, extracting, organizing, and querying this data requires specialized tools and an understanding of the system. This makes the process more challenging than dealing with a traditional database.

Hence, developers have to build indexers to address the needs of querying transaction data. For smart contract-based transactions, Application Binary Interfaces (ABI) have to be used which act as blueprints for the smart contract and enable developers to find transaction data. Whereas for some other chains like Solana in this case, developers utilise Remote Procedure Calls (RPC) to fetch transaction data from a block, pick the data relevant to their validator and delegators and code an indexer for the same.

Essentially, the indexer aggregates and summarizes the transaction “notes”. Without indexing, finding specific details like the first transaction of a wallet with a specific token would be like finding a needle in a haystack. Indexing makes navigating the vast world of blockchain data feasible and efficient.

Indexers take the fetched transactions and make a database, which can be queried. These indexers run periodically and update the database.

Luganodes’ Solana Indexer

Solana as a chain has been a mainstay for Luganodes for quite a while now. In this period, Solana has gone through multiple updates and has consistently shown promise as a major institutional player. Our last revisit involved going through their major upgrades and their path forward, which you can check out here.

As a major chain supported by Luganodes, we have put significant development effort into building indexers for Solana. Recognizing the transformative power of collaborative innovation, we have decided to open-source our Solana indexer. This move aligns with our commitment to transparency and the ethos of the Web3 community, fostering a more inclusive and robust ecosystem.

Open-sourcing the indexer allows developers worldwide to contribute to and enhance its capabilities, ensuring wider adaptability and resilience. Furthermore, by sharing our work, we're enabling a deeper understanding and potentially sparking innovations within the Solana ecosystem. With this move, Luganodes continues its commitment towards being a key contributor to the community-driven blockchain world.

Versatility of Luganodes' Indexer

At Luganodes, we are seasoned indexer builders. Indexers form an essential part of our daily workflow, enabling us to use properly formatted data in our products. The most prominent of which is the Terminal application used by our clients for portfolio management. Through this application, our indexer plays a vital role in data reporting, allowing clients to efficiently manage and analyze their portfolios. It serves as a powerful tool for extracting and interpreting the wealth of data on the Solana blockchain, transforming raw data into actionable insights.

Beyond our internal applications, our open-source Solana Indexer has a multitude of uses for the wider community. Detailed in our GitHub repository, users can find guidelines on how to leverage this indexer for their specific needs. Whether it's for developing applications, conducting comprehensive blockchain analytics, or integrating Solana staking data into existing systems, our indexer is designed for versatility and scalability.

This tool is invaluable for developers, enterprises, and blockchain enthusiasts alike, offering an accessible way to tap into the rich data landscape of Solana.


Our tool simplifies some of the most complex tasks in blockchain data management. The advantages of using our open-sourced indexer are numerous, and they include:

  • Streamlined Data Management: Users can effortlessly fetch and organize Solana staking data for their validator without needing to understand the intricate details of the underlying code.

  • Simplified Data Access: The indexer abstracts the complexities of data retrieval, making it accessible even to those with limited blockchain expertise.

  • Enhanced Data Usability: Our tool transforms raw blockchain data into a structured and usable format, enabling users to focus on analysis and application rather than data processing.

Additionally, this open-source approach encourages users to adopt and adapt our indexer for their specific needs. Whether it's for creating indexers for their own validators or creating bespoke APIs, our indexer provides a solid foundation. We strongly encourage users to:

  • Utilize our code for creating indexers for their validators, mirroring our approach to data handling and management.

  • Leverage the flexibility of our tool to build custom APIs tailored to their specific data requirements and use cases.
