A simple utility class that helps wrap and unwrap ETH on compatible networks (Ethereum, Optimism, Arbitrum One...)
npm i ethwrapper
import EthWrapper from "ethwrapper"
const ethwrapper = new EthWrapper({
rpcEndpointUrl: 'http://public-rpc-url.com',
wallet: {
address: '0xYOUR_ADDRESS_HERE',
privateKey: '0xYOUR_PRIVATE_KEY_HERE',
},
wethContractAddress: '0xWETH_CONTRACT_ADDRESS',
})
(async () => {
const wrapHash = await ethwrapper.wrap({ amount: 0.001 })
const unwrapHash = await ethwrapper.unwrap({ amount: 0.05 })
})()
EthWrapper needs three things to work :
- A public or private JSON-RPC url related to the network you want to wrap/unwrap on
- Your public and private keys in order to sign the contract calls
- The WETH contract address on the chain you are working on
