¶ Introduction

The Indexer on your bitcoin node indexes the entire bitcoin blockchain, and the resulting index enables fast queries for any given user wallet, allowing the user to keep real-time track of balances and transaction history. Since it runs on the user's own machine, there is no need for the wallet to communicate with external servers, thus preserving the privacy of the user's addresses and balances.

¶ Why use it?

This software help you connect bitcoin wallets to your RoninDojo node. An Indexer is particularly useful if you have a hardware wallet such as: Passport, Trezor, Cold Card, or Ledger. In short, it allows you to safely and privately interact with your various bitcoin wallets, trusting only your own node.

There's also the added benefit of enhancing your ability to restore existing Samourai Wallets in Dojo and allows more detailed searches when using your blockchain explorer.
