## What Is WETH (Wrapped Ethereum)?

WETH (Wrapped Ethereum) is the ERC20 form of ETH: every WETH is backed 1:1 by ETH held in the canonical WETH contract and can be converted back at any time. ETH itself predates the ERC20 standard, so DEX pools, lending markets, and NFT offer systems work with WETH instead. In practice that means a WETH wallet is an ERC20 wallet on Ethereum with one extra job: switching between ETH and WETH the moment a protocol asks for the token form.

## ETH and WETH in Your Wallet

Holding WETH changes nothing about your setup - it changes what each balance is for:

ETH balanceWETH balance

AddressYour Ethereum addressThe same address - no separate wallet or account needed
Network feesPays gas for every transaction - keep some at all timesNever pays gas - sending WETH is paid from your ETH balance
What it's forPayments, gas, stakingDEX trading, DeFi deposits, NFT offers and bids
Staking in Gem WalletYesNo - unwrap to ETH first
ConvertingWrap to WETH at 1:1 in SwapUnwrap to ETH at 1:1 in Swap

That is the whole WETH vs ETH difference in day-to-day use: same value, same address, different jobs. Nothing is lost in either direction - the only cost of switching is the network gas fee.

## How to Wrap and Unwrap ETH in Gem Wallet

Gem Wallet lets you wrap ETH to WETH and unwrap it back directly in the app through the built-in DEX aggregator - no separate DApp, browser extension, or manual contract interaction needed:

- Open Gem Wallet and tap Swap.

- Select ETH as the asset you pay and WETH as the asset you receive - or the reverse to unwrap.

- Enter the amount and confirm the transaction.

The conversion is always 1:1 - the only cost is the Ethereum gas fee, paid in ETH. Wrapping is one of the lightest transactions on Ethereum, comparable in gas to a standard token transfer. Keep a small ETH balance in the wallet: every WETH operation, including sending and unwrapping, is paid for in ETH.

## How to Buy WETH

Gem Wallet lets you buy WETH with a card through integrated providers in a few taps. In most cases, though, the more convenient route is to buy ETH first and wrap it inside the app - fiat providers quote ETH with deeper liquidity, and the wrap step costs only gas. Either way, the tokens arrive at your own Ethereum address, not an account balance held by someone else.
