What does wrapping ETH do?

Wrapping converts your native ETH into an ERC-20 token (WETH) at a 1:1 ratio. Many DeFi protocols and DEX routers only accept ERC-20 tokens, so they require the wrapped form.

Can I unwrap only part of my balance?

Yes. Unlike some wrapped assets, WETH (WETH9) supports partial unwrapping, so you can convert back any amount up to your wrapped balance.

Is the conversion always 1:1?

Yes. Wrapping and unwrapping are always 1:1. You only pay the flat Smithii fee plus the network gas for the transaction.

Wrap and Unwrap ETH Instantly on Ethereum

A wrapped native token like WETH (WETH, WBNB, WAVAX, WPOL and so on) is an ERC-20 that represents the chain's native coin at a 1:1 ratio. On Ethereum, many DeFi protocols and smart contracts require the ERC-20 wrapped form (WETH) instead of the raw ETH. This tool converts between them without any coding.

Wrapping deposits your ETH into the canonical WETH contract and mints the same amount of the wrapped token. Unwrapping withdraws it back to ETH. Unlike some chains, EVM wrapping supports partial amounts, so you can unwrap exactly what you need.

When Do You Need WETH?

You typically need WETH when providing liquidity, swapping on a DEX, or interacting with lending and staking protocols on Ethereum that only accept ERC-20 tokens. If you're adding liquidity with a ETH pair, most routers work with WETH under the hood. This wrapper handles the conversion for you in a couple of clicks.
