Key Takeaways
- Tokens vs. Coins: Tokens are customizable assets built on smart contracts (e.g., ERC-20), while coins are native blockchain assets (e.g., ETH).
- Wrapped Tokens: Track the value of another asset 1:1 by locking the original asset in a bridge contract. Examples include WBTC (Wrapped Bitcoin) and WETH.
- Purpose of WETH: Enables ETH to function as an ERC-20 token for DeFi applications (e.g., liquidity pools, auctions) where native ETH isn’t compatible.
- Interoperability: WETH exists on Ethereum and other blockchains (e.g., BNB Chain, Solana), expanding ETH’s utility across ecosystems.
Coins vs. Tokens: Understanding the Basics
Coins
- Definition: Native cryptocurrencies of a blockchain (e.g., BTC for Bitcoin, ETH for Ethereum).
- Use Cases: Gas fees, staking, governance, and direct transactions.
Tokens
- Definition: Smart contract-based assets on an existing blockchain (e.g., USDT, SHIB).
- Standards: ERC-20 (fungible tokens), ERC-721 (NFTs), etc.

What Are Wrapped Tokens?
Wrapped tokens are blockchain-agnostic representations of assets, enabling cross-chain functionality:
- Lock-Mint Mechanism: Original assets (e.g., ETH) are locked in a bridge, and wrapped tokens (e.g., WETH) are minted.
- 1:1 Peg: Each WETH equals 1 ETH in value, maintained by audited smart contracts.
Use Cases:
- Cross-chain trading (e.g., ETH on Solana via WETH).
- DeFi compatibility (e.g., Uniswap LP deposits).
Example: Wrapped Bitcoin (WBTC) brings BTC to Ethereum for DeFi use.
Wrapped Ether (WETH): Explained
Why Wrap ETH on Ethereum?
ETH is a coin, but many dApps require ERC-20 tokens. WETH bridges this gap by:
- Enabling ETH to be used in ERC-20-only protocols (e.g., OpenSea auctions).
- Facilitating seamless swaps in DEXs without manual wrapping.

ETH vs. WETH: Key Differences
| Feature | ETH | WETH |
|------------------|----------------------------------|----------------------------------|
| Type | Native coin | ERC-20 token |
| Usage | Gas, staking | DeFi, dApps |
| Supply | ~120M (circulating) | ~3.4M (wrapped) |
| Liquidity | Lower in DeFi | Higher in DEXs |

FAQ
1. What does WETH stand for?
WETH means "Wrapped Ether" — an ERC-20 version of Ethereum’s native coin (ETH).
2. How do I convert WETH back to ETH?
Swap WETH for ETH on platforms like Uniswap or centralized exchanges.
3. Is WETH safer than ETH?
Both are equally secure, but WETH relies on smart contract integrity. Always verify the contract address.
4. Can I earn interest on WETH?
Yes! Deposit WETH into DeFi protocols like Aave or Compound for yield.
Conclusion
WETH is a pivotal innovation in DeFi, solving interoperability challenges while maintaining ETH’s value. Whether you’re trading cross-chain or participating in Ethereum dApps, understanding WETH unlocks broader crypto utility.
