Mainstreet Responds to MSUSD Depegging: Will Integrate New Proof-of-Reserves Provider and Restore Independent Verification as Soon as Possible

Regarding the MSUSD de-pegging issue, Mainstreet posted a response on X, stating that market concerns have arisen around the Morpho market, proof-of-reserves, and liquidity. However, MSUSD remains fully asset-backed, and the issues at hand do not involve asset losses or insolvency. Mainstreet explained that, due to the discontinuation of the proof-of-reserves service, the oracle supporting the Morpho market is expected to pause within the next 24 hours. This development has triggered market concerns and accelerated position exits by leveraged loop-lending users, causing borrowing rates to rise significantly. From a net asset value (NAV) perspective, its core investment portfolio remains highly certain; however, trading fees, widened bid-ask spreads, market-maker discounts, and liquidity discounts—varying by maturity and position size—are present. Mainstreet added that it is currently implementing several measures: rapidly integrating a new proof-of-reserves service to restore independent verification; redeploying liquidity into the minter/Morpho ecosystem; and, if necessary, stepping in as the ultimate liquidity provider and liquidator to prevent disorderly market fluctuations. Its primary current objective is to safeguard NAV and maximize protocol liquidity. Should borrowing rates continue rising and trigger liquidations, Mainstreet stands ready to intervene as the “ultimate liquidator” to mitigate bad-debt risk. However, as it is currently the weekend, market liquidity is limited, and market-maker quotes are weaker than during regular trading hours—temporarily slowing asset exit velocity. Further clarity is expected over the coming days.
