Wrapped Ether: ERC-20 Compatibility, DeFi Uses, and Conversion
Summary
Wrapped Ether (WETH) represents Ether (ETH) in an ERC-20-compatible token format. The document explains that ETH itself does not follow ERC-20 conventions, while many DeFi applications and token services rely on them. WETH is described as maintaining a one-to-one value relationship with ETH, allowing it to be exchanged back through wrapping and unwrapping processes.
The guide outlines uses such as decentralized exchange trading, lending, staking, and liquidity provision, and gives basic Uniswap steps for converting between ETH and WETH. It also explains the general idea of wrapped tokens as representations intended to improve compatibility, sometimes created against assets held by a custodian. Its discussion is introductory rather than a technical assessment: it does not detail contract-specific risks, fees beyond noting network gas, or the mechanics that secure WETH’s peg. It also presents custody as a general feature of wrapping, though the described direct WETH conversion route is not analyzed in depth.
Key ideas
- WETH follows ERC-20 conventions, which can make it usable in applications that do not accept native ETH directly.
- WETH is presented as exchangeable with ETH at a one-to-one value ratio.
- DeFi uses described for WETH include lending, staking, and supplying liquidity.
- Wrapping can improve token compatibility, though some wrapping models rely on custodians.
- The document describes using a decentralized exchange to wrap or unwrap ETH and notes that transactions require gas.
