Wrapped Ether (WETH) is an ERC-20 representation of ETH that lets native Ether participate in token standards requiring a uniform interface, making it a common intermediate asset in DeFi workflows. Users often swap WETH when unwrapping through an exchange is more convenient than going through a smart contract directly, or when moving value out of a DeFi position into another asset. WETH is available on both Ethereum and Polygon, so network selection is a key practical consideration before initiating any swap.
Before swapping WETH, confirm which network your tokens are on — Ethereum or Polygon — and make sure the destination address and network on the receiving side match exactly, since tokens sent to the wrong network can be unrecoverable. Gas fees and settlement times differ between Ethereum and Polygon, so your choice of network affects both the cost and speed of the exchange. The rate and estimated output are shown in the swap widget before you confirm, giving you a chance to review the terms. No memo or destination tag is required for WETH on either supported network.
