Frankencoin vs Liquity V2: which borrowing protocol fits?

Frankencoin and Liquity V2 both let users borrow stablecoins against crypto collateral on Ethereum, but they serve different needs. Frankencoin issues ZCHF, designed to track the Swiss franc, and describes its backing as over-collateralized and oracle-free. Liquity V2 issues BOLD, a dollar-pegged stablecoin, against ETH, wstETH or rETH. It uses external price oracles.

The choice of currency is a major distinction: ZCHF is for users seeking Swiss-franc exposure, while BOLD is for those seeking a dollar-denominated borrowing asset. Liquity V2 also gives borrowers control over their interest rate. Frankencoin adds a savings module, FCS equity and governance, and listed payment integrations. Both are active Ethereum CDP protocols, and each has two audits listed.

Liquity V2 borrowers choose their own interest rate and can change it at any time. That choice affects their exposure to redemptions: a lower rate makes a position more likely to be redeemed against. The project advertises borrowing up to 91% loan-to-value on ETH, but high borrowing levels increase liquidation risk. Multiply offers leverage, which can amplify losses as well as exposure.

Frankencoin’s borrowing rates and savings yields are market-based, but specific figures are not published. Its full fee schedule is also not published. The homepage advertises buying ZCHF at 0% fees in some cases, while a merchant checkout partner charges a flat 1% fee. Liquity V2 does not publish specific interest-rate figures or details such as one-time fees and liquidation penalties. For both protocols, Ethereum gas costs apply, and Liquity users may also encounter fees from their chosen community frontend.

Both protocols list two audits, but auditor names and audit findings are not published. Frankencoin’s oracle-free design avoids reliance on a collateral price oracle, but its smart contracts, collateral and liquidation or auction mechanisms still carry risk. Its FCS token represents a share in the equity reserve, so holders can absorb protocol losses. Frankencoin also has multiple frontends, making it important to verify an interface before connecting a wallet.

Liquity V2 describes its contracts as immutable and without admin keys. That removes the risk of an administrator changing the contracts, but also means a flaw cannot be patched by upgrade. Its external price oracles remain a dependency, and borrowers can be liquidated if collateral prices fall. Liquity does not operate its own frontend and says it has not vetted community operators. Neither design removes the risks of borrowing or smart-contract use.

Choose Frankencoin if Swiss-franc exposure is your priority, you value an oracle-free stablecoin design, or you want to explore ZCHF’s savings module and payment integrations. Keep in mind that its market is narrower than major dollar stablecoins, its fee details are limited, and FCS holders bear equity-reserve losses.

Choose Liquity V2 if you want to borrow BOLD against ETH, wstETH or rETH and prefer to set your own interest rate. Its immutable, no-admin design may also suit users who value contracts that cannot be changed after deployment. In return, you must monitor your rate and redemption exposure, assess a community-run frontend, and account for oracle and liquidation risk. Neither protocol is the better choice for everyone: the stablecoin you want and the risks you can manage should decide it.
