Ethereum Virtual Machine · Acts onchain
Wraps native ETH into WETH, or unwraps WETH back to native ETH, on the current chain. Wrap sends the amount by value to the chain's wrapped native contract; unwrap calls its withdraw. Both are one-to-one with no fee. Reach for it before a step that takes only the ERC-20 form, such as a Uniswap V2 pair or a lending market, or after one that pays out WETH when the next step needs native ETH.
Unwrap WETH to ETH
1·Take
Take declares a named parameter called amount whose value the caller supplies when they run the plug, so the quantity is not fixed here but chosen at execution.
2·Wrap or unwrap
Reading [the value in slot "0.0"], the unwrap action converts that amount of WETH at 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 into native ETH at 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, wired to the caller-supplied amount from the prior step.
