Wrap & Unwrap ETH
Ethereum Wrapper
Ethereum Wrapper: turn ETH into WETH and back in one transaction. Wrapped ETH is what pools, routers and lending markets actually hold.
How to use the Ethereum Wrapper
- Connect your Ethereum wallet
- Choose Wrap (ETH to WETH) or Unwrap (WETH to ETH)
- Enter the amount you want to convert
- Confirm the fee transaction and then the wrap transaction
- Your WETH (or ETH) is updated within seconds
Benefits of Wrapper
One transaction
send ETH, receive WETH, or the other way round
Always one for one
the wrapper holds your ETH and issues the same amount
Any amount
wrap what a single trade needs, unwrap part of it later
What contracts expect
Uniswap pools and DeFi protocols hold WETH, not ETH
Nothing custodial
the wrapper contract holds it and you redeem whenever you want
No coding
no router call to compose and no contract to interact with by hand

In value, yes, always one for one and redeemable at any time. In behaviour, no: WETH is an ERC-20 that contracts can move with an approval, and ETH is the network currency that only you can send. That difference is the entire reason WETH exists.
It deposits your ETH into the wrapper contract, which issues you the same amount of WETH, an ERC-20. Unwrapping returns the ETH and burns the WETH. The rate is one for one in both directions and there is no lock-up.
Because ETH is the network currency and not a token: it has no transfer or approve function for a contract to call. Anything written against the ERC-20 standard needs WETH instead, which is most of DeFi.
Yes, any amount at any time. The rest stays wrapped and usable.
The wrapper is one of the most used contracts on any EVM chain and does one thing: hold ETH and issue WETH against it. Your claim is the WETH in your wallet, redeemable whenever you want.
A small fee shown before you sign, plus Ethereum gas. The conversion never takes a cut: what goes in comes out.
Why ETH cannot be traded directly
ETH predates the ERC-20 standard, so it has no transfer, no approve and no allowance. Every contract written against the standard needs a token that does, which is what WETH is: a contract that holds your ETH and issues an ERC-20 against it, one for one. That is why a pool pairs against WETH and not against ETH, and why routers wrap for you behind the scenes.
