# Odos

rotki decodes Odos aggregator trades across several EVM chains. You choose which RPC endpoint handles the queries.

## Features

- Odos aggregator swaps decoded as swap events.
- Decoded on Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Smart Chain, and Scroll.

## Setup

1. In rotki, add your address under a chain where you've used Odos.
2. Open History and let the initial sync run. Odos swaps are decoded automatically.

## FAQ

### Which RPC does rotki use for Odos activity?

rotki is a local application that talks directly to the RPC endpoint you configure for each chain - the public default, a third-party provider, or your own node. Each query goes from your computer to that endpoint without passing through any rotki-operated server.
