Implement a leveraged strategy on wstETH using the aave protocol. The vault essentially manages a CDP with
wstETHcollateral andETHdebt.Configuration:
targetLTV: the Loan to Value the vault looks to maintainmaxLTV: the maximum Loan to Value the vault can reach before triggering a rebalanceHigh level view of the flows:
Deposit-> takes wstETH from user and deposits into lending protocolWithdraw-> if the amount requested to withdraw gest the vault abovemaxLTV, repay part of the debt (full repay iftotalAssetswithdraw) and withdraw that amount. If not, simply withdraw amount.Increase leverage-> if vault LTV is lower than target, the vault does a loan of ETH, wraps into wstETH, deposits into CDP.Reduce leverage-> if vault LTV is higher than target, the vault does a flash loan of ETH, repay part of debt, withdraws wstETH, swaps for ETH (needed to repay the flashloan)
