3Jane USD3

USD3 is a yield-bearing ERC-4626 token issued by 3Jane, a credit protocol that connects pooled stablecoin capital with fintech lenders who need warehouse financing for loan origination. Depositors contribute USDC and receive USD3 in return, placing them in the senior tranche of the capital structure, meaning they have a prior claim on repayments relative to junior participants. The protocol addresses the problem of fintech lenders lacking efficient access to programmatic, asset-backed credit facilities, while giving stablecoin holders a structured way to participate in that lending activity.

USD3 is an ERC-4626 tokenized vault on Ethereum, meaning depositing USDC mints USD3 at a ratio governed by the vault's accumulated assets, and redeeming USD3 returns the underlying USDC plus any accrued yield. 3Jane allocates the pooled capital into approved credit facilities — warehouse lines, participations, and forward-flow loan purchases — while the fintech lenders on the other side handle borrower underwriting and servicing. A second token, sUSD3, is created by staking USD3 and sits in the junior tranche, absorbing losses before they reach USD3 holders.

The data provided does not include an explicit fee-rate figure or a breakdown of protocol revenue, so fee-based measures cannot be reported from this source. Yield in the system derives from interest paid by fintech lenders on the credit facilities 3Jane funds; that yield is distributed across the two tranches, with sUSD3 receiving the junior share and USD3 holders receiving the senior share. The absence of a fee-stream entry in the stored metrics means any protocol margin retained by 3Jane itself is not quantified here.
