WETH Gateway

If you need to use native ETH in the protocol, it must first be wrapped into WETH. The WETH Gateway contract is a helper contract to easily wrap and unwrap ETH as necessary when interacting with the protocol, since only ERC20 is used within protocol interactions.
function depositETH(address onBehalfOf, uint16 referralCode)
Deposits WETH into the reserve, using native ETH. A corresponding amount of the overlying asset (bTokens) is minted.
| Parameter Name | Type | Description |
|---|---|---|
function withdrawETH(uint256 amount, address to)
Withdraws the WETH _reserves of msg.sender.
| Parameter Name | Type | Description |
|---|---|---|
function borrowETH( uint256 amount, address nftAsset, uint256 nftTokenId, address onBehalfOf, uint16 referralCode )
Borrow WETH, unwraps to ETH and send both the ETH and DebtTokens to msg.sender, via onBehalf argument in LendPool.borrow.
function repayETH( address nftAsset, uint256 nftTokenId, uint256 amount )
Repays a borrow on the WETH reserve, for the specified amount (or for the whole amount, if type(uint256).max is specified).
function auctionETH( address nftAsset, uint256 nftTokenId, address onBehalfOf )
Auction a borrow on the WETH reserve.
function redeemETH( address nftAsset, uint256 nftTokenId, uint256 amount, uint256 bidFine)
Redeems a borrow on the WETH reserve.
function liquidateETH( address nftAsset, uint256 nftTokenId, uint256 amount)
Liquidates a borrow on the WETH reserve.
