Proposal to Utilize Frontier Reserves to Pay Down Bad Debt

Forum Post: https://forum.inverse.finance/t/use-frontier-reserves-to-pay-down-bad-debt/340

Summary

Utilize the Frontier reserves to reduce the bad debt on the account from the Inverse Finance Frontier price manipulation incident of April 2nd 2022, 0xeA0c959BBb7476DDD6cD4204bDee82b790AA1562.

Background

Frontier, Inverse Finance’s now-deprecated variable-rate lending market, accumulated reserves by taking a 20% fee on the interest paid by borrowers back when it was active. These reserves were/are in the form of DOLA, ETH, WBTC, YFI and xSUSHI. Shortly after the April 2nd 2022 exploit, the interest rate on ETH, WBTC and YFI was set to 0% to stop borrow (and supply) balances from accumulating further, so no further reserves accrued in these assets. Given the vast majority of current DOLA borrows on Frontier are bad debt, in April 2023 the reserve ratio set to 100% in order to direct 100% of borrowers interest to the reserves, this was to stop bad debt from artificially inflating on-chain fed revenue.

The current reserves in Frontier are the following:

Asset	Amount	USD
DOLA	225,908	~$225.9k
ETH	9.763	~$20.0k
WBTC	0.732	~$27.1k
YFI	0.433	~$3.7k
xSUSHI	313.15	~$498
TOT	N/A	$277.2k

Execution

Given there is no liquidity available in the ETH/WBTC/YFI markets to withdraw, this proposal will need to first add liquidity (via bad debt repayment) in order to pull the reserves.

Treasury pays down 9.763 ETH, 0.732 WBTC and 0.433 YFI of bad debt, bringing this liquidity into the markets
Reserves of 9.763 ETH, 0.732 WBTC, 0.433 YFI, 228k DOLA and 313.10 xSUSHI pulled out of the markets into the Treasury
Use 229k DOLA to repay bad debt
The xSUSHI is sent to the TWG in order to be swapped to DOLA and used to repay DOLA bad debt.

Note: More DOLA reserves are pulled down than there are at the current time of writing as DOLA reserves are continuously growing (accruing interest). By the time this proposal is executed, there will be more than 228k available.

Results

This proposal will result in ~$280k of both DOLA and non-DOLA bad debt being repaid in total. The net impact on the DAO Treasury will be 0.
