 The Transaction Indexer ([tx-indexer](https://github.com/gnolang/tx-indexer)) is the primary tool Gno.land uses to index its networks. It is in charge of keeping up with block production, fetching new data, indexing it, and serving it to users while providing filtering and subscription capabilities. The tx-indexer creates versatility and ease of use when using on-chain data, which is one of the key aspects of a fully functioning decentralized application.
