# Ethereum

Add your Ethereum addresses (or ENS names, or read-only watch addresses) to rotki and you get balances, full transaction history, ERC-20 holdings, NFTs, and decoded DeFi activity for every protocol rotki ships a decoder for - all queried directly from the RPC endpoint you choose.

## Features

- ETH and ERC-20 balances queried per tracked address against the RPC you configure.
- Transaction history decoded into readable events: transfers, swaps, approvals, deposits, withdrawals, protocol interactions.
- Dedicated decoders for a wide range of Ethereum protocols (Aave, Curve, Uniswap, MakerDAO, Lido, Morpho, Yearn, Pendle, and many more), so activity is tagged with the right counterparty instead of appearing as raw calls.
- NFT tracking for ERC-721 and ERC-1155 holdings, including ENS names.
- Primary ENS name resolution: tracked addresses display their primary ENS name across rotki.
- Free-tier tracking has no address-count limit; track as many Ethereum addresses as you like.

## Limitations

- Ethereum-validator tracking (beacon chain balances, withdrawals, MEV, block-proposal rewards) is a separate, paid feature. See the Ethereum Validators integration page for details.

## Setup

1. In rotki, open Blockchain Balances → Ethereum → Add address. Paste your address or ENS name, optionally with a label.
2. Optional: configure your preferred Ethereum RPC endpoint in Settings (a public default is provided). Pointing rotki at your own geth/reth/erigon node is the most private and reliable setup.
3. In rotki, open History and let the initial sync run. The first sync of a long-history wallet can take a few minutes; subsequent syncs are incremental.

## FAQ

### Do my Ethereum addresses leave my machine?

No. rotki is a local application that talks directly to the Ethereum RPC endpoint you configure - the public default, your own node, or a provider like Infura/Alchemy. The query goes from your computer to that endpoint without passing through any rotki-operated server.

### Do I need to give rotki a private key or seed phrase?

No. rotki is read-only. You only ever add public addresses or ENS names.

### Can I run rotki against my own Ethereum node?

Yes. Point rotki at your own RPC endpoint (geth, reth, erigon, nethermind, etc.) in Settings.

### Does rotki decode my DeFi activity automatically?

Yes. rotki ships dedicated decoders for the major Ethereum DeFi protocols, so transactions show up as readable, counterparty-tagged events instead of raw call data.
