Product Focus
A few years ago, Tokeny encountered some challenges in maintaining and scaling its infrastructure as blockchain data indexing can be quite complex with advanced smart contracts. We were limited by existing indexing tools like The Graph and decided to invest massively in the development of our own indexer solution for our tokenization platform.
Issues such as unsynchronized blockchain data and disruptions to other operations during token and event indexing were costly to maintain and hard to use. With our in-house indexer, these challenges were effectively resolved.
Opening Our Indexer to Third-Parties
This experience led us to realize that many other companies shared similar frustrations with existing indexing solutions, regardless of their size or industry. Recognizing the widespread need for a reliable indexer solution, we decided to launch Leandexer, a standalone version of our in-house indexer, available as a SaaS solution.

What is Leandexer?
Leandexer.com offers a blockchain indexer-as-a-service solution, providing live streams of blockchain data for both individuals and businesses, on any EVM-compatible blockchain. By offering a user-friendly platform and a robust API, it enables the setup of alert notifications from blockchains, such as events triggered by smart contracts. With its no-code approach, Leandexer simplifies blockchain interaction for everyone, regardless of technical expertise. Crucially, it guarantees uninterrupted access to up-to-date blockchain data feeds without downtime, all while ensuring low maintenance costs.
Having already processed over 3 billion blockchain events via the Tokeny platform in the past few years, Leandexer has proven its reliability and efficiency. We are now getting ready to make the solution available to developers, traders, and researchers.
