# Asset Guide - wETH

## What is wETH?

Wrapped Ether (wETH) is an ERC20 version of ETH, enabling compatibility with DeFi protocols, DEXs, and EVM based applications. It allows ETH to be used like any other ERC-20 token across various ecosystems.

### Where do I get wETH?

You can get wETH from:

* **On-chain swaps** via Sei based DEXs like [**Symphony**](https://symph.ag/).
* **Centralized Exchanges** like Binance, Coinbase, Kraken, OKX.
* **Manual wrapping** of ETH via Uniswap or wallets like MetaMask and Rabby.
