WETH (Wrapped Ether) Overview

When working with WETH, Wrapped Ether, an ERC‑20 version of Ethereum’s native coin designed for seamless use in DeFi protocols. Also known as Wrapped ETH, it bridges the gap between Ether’s native utility and the token standards required by most smart contracts.

To understand why WETH exists, you first need to know Ethereum, the blockchain platform that powers smart contracts and dApps. Ethereum’s native currency, ETH, is not an ERC‑20 token, which means it can’t be directly placed in many automated market makers or lending platforms. That’s where the ERC‑20 token, a standard for fungible tokens on Ethereum comes in. By wrapping ETH into an ERC‑20 wrapper, WETH becomes interchangeable with any other token that follows the same rule set.

In the world of DeFi, decentralized finance, a suite of services like lending, borrowing, and trading that run on smart contracts, the ability to move value quickly and cheaply is crucial. WETH enables users to provide liquidity to liquidity pools, smart contract vaults that hold pairs of tokens for automated market making without the friction of custom bridge contracts. As a result, swapping, staking, and borrowing become as simple as interacting with any other ERC‑20 token.

Why WETH Matters in DeFi

Every major decentralized exchange—Uniswap, SushiSwap, Curve—accepts WETH as a base pair. When you trade ETH for another token, the platform first wraps your ETH into WETH, executes the swap, then unwraps the result back to ETH if you request it. This extra step is invisible to you but essential for the routing algorithms that power optimal trade paths. Beyond trading, lending platforms like Aave and Compound treat WETH just like DAI or USDC, letting you earn interest or use it as collateral for borrowing other assets.

Because WETH follows the ERC‑20 standard, developers can write generic smart contracts that work with any token, including WETH, without writing special case logic for native Ether. This uniformity speeds up the creation of new protocols, from yield farms to synthetic asset issuers. Moreover, cross‑chain bridges often require an ERC‑20 token as the source asset, so WETH becomes the preferred vehicle for moving value from Ethereum to Layer‑2 solutions or other blockchains.

Another practical benefit is gas efficiency. Wrapping and unwrapping ETH only costs a single transaction each, which is cheaper than calling custom adapters on a per‑protocol basis. For high‑frequency traders or bots, that small saving adds up quickly and can make the difference between profit and loss.

All of these reasons—compatibility, ease of use, and cost efficiency—make WETH a foundational piece of the DeFi puzzle. Whether you’re a beginner looking to dip a toe into crypto or an experienced trader optimizing routes, understanding WETH is a stepping stone to deeper participation.
