In plain English
What Wrapped token means
A wrapped token gives an asset a usable form in a different environment. Wrapped Ether, or WETH, represents ETH in the ERC-20 format so applications built for ERC-20 tokens can handle it consistently. Other wrapped tokens are created through bridges to represent assets originally native to another blockchain.
Why it matters
The word “wrapped” explains token functionality, not safety or legal ownership. Before using a wrapped token, users should identify the issuer or bridge, collateral arrangement, redemption process, contract address, and chain. Those details determine whether it can be exchanged for, or remain aligned in value with, the referenced asset.
Example
A user deposits 3 ETH into a WETH smart contract and receives 3 WETH under a one-to-one conversion rule. The WETH can interact with ERC-20-based contracts, while the user needs to keep some native ETH separately to pay Ethereum gas fees. Unwrapping burns WETH and returns ETH under the contract’s rules.
Quick answers
Common questions
Is WETH a different economic asset from ETH?+
WETH is designed as an ERC-20 representation of ETH, commonly convertible one-for-one through its wrapping contract. It differs technically from native ETH, however: native ETH pays Ethereum gas, while WETH is used where ERC-20 compatibility is required.
Are all wrapped tokens backed one-for-one?+
No universal rule applies. Some use onchain lock-and-mint mechanisms, while others depend on custodians or bridge reserves. The relevant question is how the specific token is issued, collateralized, audited if applicable, and redeemed.
