Inverse Finance is excited to announce the launch of the new cvxFXS market on FiRM. Our CRV and cvxCRV markets have been very successful and we look forward to a similar uncorking of demand for cvxFXS. 

This new cvxFXS market provides FXS holders with access to liquidity on their FXS assets without locking their FXS as veFXS, which is non-tradeable and not available for use as loan collateral. In addition, cvxFXS deposited on FiRM still receives cvxFXS staking yield, currently more than 9% APY.

cvxFXS is a yield-bearing token that is generated when users stake and lock FXS tokens on Convex Finance. It is a great collateral choice for FiRM because it offers real advantages as a collateral token. 

  • In addition to receiving CVX yield from convex, cvxFXS tokens receive the yield that a user would get from just staking FXS tokens in Frax Finance. This yield can be used to repay loans taken out on FiRM, or it can be used to generate additional income.

  • FiRM Security: Your cvxFXS is never loaned to another user, but rather you maintain custody of your cvxFXS in your Personal Collateral Escrow. This also means that your assets are not pooled together with other assets, which avoids common risks in pooled lending protocols.

Who Are Frax Finance?

FXS is the governance token for the Frax Finance DAO, and it governs parameters for their three stablecoin products: staked ETH, a USD pegged FRAX, and inflation adjusted FPI. Frax Finance is a steadfast “curve wars” partner to Inverse Finance and we’re happy to deepen our ties by opening the cvxFXS market. This market provides a simple way for participants in the curve ecosystem to access liquidity against their FXS portfolio while getting the benefits of locked staking.

How To Borrow with cvxFXS In FiRM

  1. Head to the Inverse Finance website and click "Borrow."

  2. Confirm that there is DOLA liquidity available in the cvxFXS market. Especially for new markets, we add liquidity slowly.

  3. Acquire cvxFXS on the open market or convert FXS into cvxFXS on Convex’s site to use as collateral.

  4. Choose between the regular mode or walkthrough mode (simpler interface) on the FiRM app, depending on your desire for technical detail about your transaction.

  5. Decide the amount of cvxFXS you want to deposit.

  6. Decide how much DOLA you want to borrow and for how long.

  7. Click the “Auto-buy DBR” button.

  8. Review your loan in the “summary” information and confirm that everything is correct.

  9. Approve the interaction in your wallet.

  10. Execute the transaction to deposit, borrow and buy DBR in FiRM.

Enjoy your fixed-rate loan!
