3Jane Options Review 2026: From Options Vault to Credit Protocol

3Jane is a credit protocol on Ethereum. An aggregate data listing from June 2024 files it under options vaults and describes it as a derivatives protocol using restaking and cash-and-carry. The current homepage presents something different: "cryptonative credit creation", centered on USD3, a credit-backed yieldcoin.

USD3 earns from warehouse facilities, forward-flow programs and credit lines that fund fintech originators. Public reporting report that the project raised $5.2M in a round led by Paradigm and launched with a $10 million senior warehouse facility and a $50 million forward-flow programme. Other snippets name Coinbase Ventures and Wintermute Ventures as backers. These are single-source reports.

The homepage compares USD3 with Aave aUSDC at 4% and Ethena sUSDe at 7%, against 15-20% for sUSD3. TVL under the older options-vault listing is about $105,729, which is small and does not necessarily reflect the current credit product.

Suppliers deposit USDC into the 3Jane protocol and receive USD3. The protocol deploys that capital into credit products: warehouse facilities, forward-flow programs and credit lines for fintech lenders and crypto-native borrowers. Interest paid by borrowers is what backs the yield on USD3.

Suppliers who want more yield can stake USD3 to get sUSD3. The homepage describes sUSD3 as levered exposure to the pool and says it autocompounds. In practice, this suggests it takes more of the credit risk in return for a higher rate.

On the borrowing side, fintechs can sell a loan portfolio or collateralize via an SPV, while cryptonatives can connect credit, DeFi, exchange or bank data for a line of credit. The project's research pages also describe Levered Callable Capital, a way to earn commitment fees by committing capital that is not yet drawn.

The homepage does not publish a fee schedule. It does show headline yields of 6.30% for USD3 and 13.23% for sUSD3, and the documentation and protocol app are where users would find any management, performance or borrowing fees.

On Ethereum, users also pay normal network gas fees when minting, staking or redeeming. Borrower pricing for the credit lines is not stated beyond the claim that economics improve as borrowers scale.

Aggregate data lists two audits, but the homepage does not name the auditors. Smart-contract risk applies to all deposits, and the credit design adds counterparty risk: returns depend on borrowers repaying, and sUSD3 absorbs levered exposure to the pool.

Part of the structure sits off-chain, including underwriting, SPVs and warehouse agreements, so users rely on the protocol's documentation and reports for transparency. The site links Terms of Service and Disclaimers, and regulatory status is not described on the homepage. No hacks or incidents appear.

3Jane is for DeFi users comfortable with credit risk who want yield above standard USDC lending, and for fintech lenders seeking on-chain capital. It is a poor fit for anyone who wants simple, fully collateralized exposure or cannot tolerate losses on a stablecoin-like position.
