Alpha USDC Delta V2 vault on Morpho has 27% exposure to mSY with full utilization; Accountable terminated proof-of-reserves verification for Mainstreet due to failed standards.
Security & Exploits ·
The Alpha USDC Delta V2 vault on Morpho holds $17 million in exposure to mSY (Main Street Yield), representing 27% of the vault's total allocation, with the position fully utilized. Mainstreet offered proof-of-reserves verification through por.mainstreet.finance, but Accountable has terminated its agreement with the platform after determining it cannot meet established verification standards.
The mSY market itself is currently at 100% utilization, with borrowers paying rates near 100% annual percentage yield. According to available accounts, large borrowers have not been repaying positions despite the elevated rates. Mainstreet operates as an off-chain strategy claiming to generate 12% returns through box spread arrangements, leaving limited transparency into underlying mechanics or collateral backing.
The verification termination removes an audited layer of attestation for mSY's reserves and operations. The combination of full utilization in a concentrated off-chain strategy, the withdrawal of third-party verification coverage, and the borrower repayment dynamics remain open questions about the vault's actual risk exposure and mSY's operational health.
