crvUSD vs Resupply: Borrowing model and risk (2026)

Both protocols are Ethereum CDPs, but they support different borrowing strategies. crvUSD lets users mint a dollar-pegged stablecoin against approved crypto collateral. Its liquidation system uses Curve’s LLAMMA design, and autonomous Peg Stability Reserves aim to keep crvUSD near $1. New collateral requires DAO approval.

Resupply is built around lending positions rather than direct crypto deposits: users put crvUSD or frxUSD positions from Curve Lend or Fraxlend up as collateral and borrow reUSD. They keep earning the underlying lending yield while borrowing. Resupply also offers an Insurance Pool intended to fund liquidations and act as a reserve if approved collateral fails. This structure is more specialized, with risks tied to Resupply and the lending markets it depends on.

crvUSD does not publish a fee schedule. Its borrow rates, any minting charges and savings yield are not stated, and rates vary by market. Check the specific Curve market before opening a position; every Ethereum transaction also incurs gas costs.

Resupply publishes a borrow-rate formula: the rate is the higher of half the market lending rate, half the sfrxUSD rate, or 2%. That establishes a minimum rate, not a fixed borrowing cost. The Insurance Pool earns a fee when used for liquidations, and a share of protocol revenue goes to its depositors. Current rates and fees should be checked in the app and docs before transacting, along with Ethereum gas. Neither protocol’s published material here establishes a single all-in cost that applies to every user or market.

Both protocols involve smart-contract, collateral and peg risks, and both have two audits listed. For crvUSD, crypto collateral can fall far enough to trigger liquidation; the peg also depends on Peg Stability Reserves and Curve pool liquidity rather than a fiat-backed reserve. The audit scope and findings are not detailed.

Resupply adds dependencies on Curve Lend and Fraxlend, plus the risk that reUSD loses its peg. Its Insurance Pool is designed to absorb liquidation losses, but depositors accept the risk of covering losses from distressed collateral. A reported June 2025 exploit took nearly $9.6 million. Resupply does not say how losses were handled or what changed afterward. That incident is a significant reason to examine its official post-mortem and docs before considering the protocol. Neither protocol is risk-free simply because it lists audits or describes its contracts as non-custodial.

Choose crvUSD if you want to borrow a Curve stablecoin directly against approved crypto collateral and value its distinct liquidation design. It also has the larger TVL of the two, about $126.6 million compared with Resupply’s $50.2 million. That difference is a snapshot, not a guarantee of future liquidity or safety. If you want a yield-bearing option, crvUSD also has savings crvUSD (scrvUSD).

Choose Resupply only if its specific structure fits your plan: borrowing reUSD against an existing crvUSD or frxUSD lending position while retaining that position’s yield. Its rate formula is more explicit, but can change with market rates, and the reported exploit adds substantial uncertainty. Do not treat its advertised leverage potential as a reason to borrow more. Compare market terms, liquidation conditions and the risks of each underlying lending market before acting.
