WETHGateway
WETHGateway
The WETH Gateway contract is a helper to easily wrap and unwrap ETH (or native currency of chain eg. MATIC, AVAX etc) as necessary when interacting with the protocol.
Write Methods
depositETH
function depositETH(address pool, address onBehalfOf, uint16 referralCode)
Supplies the msg.value
amount of ETH (or native chain token) into the Themis pool, minting the same amount of corresponding tWETH and transferring them to the onBehalfOf
address.
Ensure that the depositETH()
transaction also includes the amount of ETH you are supplying in the msg.value
.
Call Params
withdrawETH
function withdrawETH(address pool, uint256 amount, address to)
Withdraws amount
of the WETH (or wrapped native chain token), unwraps it and transfers ETH (or native chain token) to the to address.
💡 Ensure you set the relevant aToken
allowance, before calling this function, so the WETHGateway
contract can transfer the associated aWETH.
Call Params
repayETH
function repayETH(address pool, uint256 amount, uint256 rateMode, address onBehalfOf)
Repays onBehalfOf
's debt amount of ETH () which has a rateMode
.
Ensure that the repayETH() transaction also includes the amount of ETH you are repaying in the msg.value .
borrowETH
function borrowETH(address pool, uint256 amount, uint256 interestRateMode, uint16 referralCode)
Borrows amount
of WETH with interestRateMode , sending the amount of unwrapped WETH to msg.sender .
Call Params
withdrawETHWithPermit
function withdrawETHWithPermit(address pool, uint256 amount, address to, uint256 deadline, uint8 permitV, bytes32 permitR, bytes32 permitS)
Withdraws amount
of the WETH (or wrapped native chain token) without a separate approval tx. The ETH (or native chain token) is sent to the to address.
Call Params
emergencyTokenTransfer
function emergencyTokenTransfer(address Token, address to, uint256 amount)
Method for ERC20 recovery in case of stuck tokens due direct transfers to the contract address.
Can be called only by the owner of the contract i.e. Themis Governance
emergencyEtherTransfer
function emergencyEtherTransfer(address to, uint256 amount)
Method for ETH (or native chain token) recovery in case of stuck ETH due selfdestruct or transfer ether to pre-computated contract address before deployment.
Can be called only by the owner of the contract i.e. Governance.
View Methods
getWETHAddress
function getWETHAddress()
Returns the WETH address used by the WETHGateway.
