What does it do?
Add functions expected by many contracts interacting with an ERC20 contract representing the native currency.
While on Ethereum it actually creates new tokens (wETH, 1 wETH = 1 ETH), in our case it interacts directly with the native balance. We thus just provide functions that keeps the amount intact.
What important points reviewers should know?

What alternative implementations were considered?
Are there relevant PRs or issues in other repositories (Substrate, Polkadot, Frontier, Cumulus)?
