crvUSD vs Frankencoin: Which stablecoin fits? (2026)

Both protocols let users borrow a stablecoin against crypto collateral, but the currencies they target are different. crvUSD is designed to stay near $1 and is issued on Ethereum. Frankencoin’s ZCHF targets a 1:1 value with the Swiss franc, offering a currency exposure that is less common in DeFi.

Their liquidation approaches also differ. crvUSD uses Curve’s LLAMMA, a lending-liquidating AMM design intended to soften liquidations rather than rely on a plain auction. Frankencoin describes itself as oracle-free and uses liquidation and auction mechanisms to maintain backing. Neither approach removes the risk that falling collateral values can result in losses. Frankencoin is smaller by TVL, at about $60 million compared with roughly $127 million for crvUSD. Those figures indicate relative scale, not a guarantee of liquidity or stability.

crvUSD suits users who want dollar exposure and are interested in Curve’s lending markets. Its savings product, scrvUSD, turns deposited crvUSD into a yield-bearing stablecoin that can be used elsewhere in DeFi. Curve also has Peg Stability Reserves intended to help keep crvUSD near $1, though the peg depends on those contracts and Curve pool liquidity rather than a fiat-backed reserve.

Frankencoin is the more direct fit for someone who specifically wants Swiss-franc exposure. Its ZCHF savings module offers market-based yield, and the project lists payment integrations such as Spar stores, GnosisPay cards and Mt Pelerin IBAN links. These integrations involve third parties, whose terms and eligibility rules apply. The project says it has had no significant peg deviations since 2023, but that does not eliminate peg, collateral or liquidity risk. Its own description of Swiss-law and MiCAR compliance does not detail a licence or regulator.

Neither protocol publishes a complete fee schedule or borrowing rates, so you cannot compare the full cost of borrowing from the published rates alone. crvUSD also does not state minting charges or savings yield publicly; rates and market details can vary by market. Ethereum gas applies to transactions on both protocols.

Frankencoin advertises buying ZCHF at 0% fees for some methods, including bank transfer through Mt Pelerin. That statement does not cover every way to buy, borrow or use ZCHF. Its project information also says Spar payments cost about two-thirds less than Twint or card payments, while PrivCart charges a flat 1% merchant-checkout fee. These are specific payment examples, not a general protocol fee schedule. Compare the terms shown for the particular borrowing, savings or payment service you plan to use, including any third-party charges.

Both systems are non-custodial smart-contract protocols, but that does not make them risk-free. Their collateral is locked in contracts, and falling collateral prices can trigger liquidation. crvUSD’s peg depends on Curve’s Peg Stability Reserves and pool liquidity. Frankencoin’s ZCHF relies on its collateral and liquidation mechanisms, while the FCS share token absorbs protocol income and losses; FCS holders therefore carry equity-reserve risk.

Two audits are listed for each project, but neither publishes the auditors or audit findings in the information described here. Do not treat the audit count as a guarantee against bugs or failed liquidations. Frankencoin also has multiple frontends, so verify that you are using a legitimate interface. With either protocol, check the current market parameters and understand what happens to your collateral before opening a position.

Choose crvUSD if you want a dollar-pegged stablecoin, plan to use Curve’s Ethereum markets, and value its LLAMMA liquidation design or scrvUSD savings option. Its larger TVL of the two may be relevant when assessing scale, but it does not assure that a position can avoid liquidation or that the peg will hold.

Choose Frankencoin if Swiss-franc exposure is the deciding factor, or if its savings and listed payment integrations match your intended use. Be comfortable with the narrower CHF market and understand that FCS holders absorb equity-reserve losses. Frankencoin has a higher ease-of-use rating in this comparison, but neither protocol publishes enough fee and rate details for a complete cost comparison. In either case, review the specific market terms, collateral risks and Ethereum gas costs before depositing or borrowing.
