Ethereum mainnetTransactions use real assets. Access is KYC-gated; review the legal and risk disclosures before transacting.

How the Vault works

Depositors provide capital through two tokens. Borrowers are financed against specific, named collateral. Between them sits a dual record: legally enforceable off-chain, visible on-chain, kept in sync.

How depositors earn

Two tokens keep the stable dollar separate from the investment. Hold USDfr as a dollar, or stake it into sUSDfr and get invested in the loan book.

The depositor path, end to end.

Minting and redeeming are KYC-gated. Holding and viewing are open to anyone. Redemption settles in fixed windows called epochs, first in, first out, paced by the cash the book receives.
01Connect & verifyConnect a wallet. Minting and redeeming are KYC-gated; holding and viewing are open.
02Mint USDfrDeposit an approved stablecoin, receive USDfr 1:1. Idle reserves sit in short-term instruments.
03Stake to sUSDfrDeposit USDfr into the ERC-4626 vault and receive sUSDfr shares at the current exchange rate.
04Net performance accruesRealized facility and reserve income enters the exchange rate, net of protocol fees. Credit losses can lower the per-share rate. Yield is variable.
05Redeem via the queueRequest redemption. Requests join the redemption queue, which settles in fixed windows (epochs), first in, first out, as loan repayments come in. Then redeem USDfr back to stablecoin.

What the protocol takes, and when.

Fees are charged on realized performance, not on projections. Every rate below is prospective and capped. Final fees are set in definitive documents and may vary by sector and facility.

Fee stack: sUSDfr
Origination feeProposed: up to 2% of funded principal, charged once when a facility is funded.
Share of interestProposed: up to 10% of gross interest received. The balance goes to sUSDfr stakers.
Performance fee10% of vault profit above one protocol-wide high-water mark. Timelocked governance may change this prospectively, up to a 20% cap.
Management feeStarts at 0%. May change prospectively up to 2% per 365-day year. Each change locks in fees owed at the old rate first.
How fees are paidVault fees mint shares to the protocol rather than remove backing assets.
High-water markGlobal, not personal to your entry price. Enter during a drawdown and you share fee-free recovery to the old peak. Crystallized fees are not clawed back after a later loss.

Two records, always in step.

Every facility exists in two synchronized records. Off-chain: an SPV holds the position, the security interest is perfected (UCC-1 and assignment), cash moves through escrow and controlled accounts. On-chain: the loan NFT is the position of record, the lender register is reconstructable from events, and the payment waterfall runs automatically. Neither side may advance without the other. The NFT cannot mint until the legal facts are attested, and escrow cannot release until the NFT exists. In default, both act at once.
