## Summary

Use Resupply at resupply.fi only if you already understand Curve Lend or Fraxlend and you want to mint reUSD against collateral that keeps earning. Skip Resupply as a first protocol — and read the June 2025 exploit first. Resupply Summer (from 3 August 2026) adds emissions, not a buy call. Educational research, not financial advice.

## Should you use Resupply?

Only if Curve Lend or Fraxlend collateral is already a tool you understand and you want extra reUSD liquidity without selling that yield. Skip it as a first DeFi app. Convex and Yearn co-built it; that is provenance, not insurance. Read /corrections/ for the exploit claim we already had to reverse.

Live TVL sits on DeFiLlama. Our rankings table was stamped 2026-08-27. TVL is assets locked — not a safety score and not a reason to deposit.

## What is Resupply and how does positive carry work?

You deposit a Curve Lend crvUSD or Fraxlend frxUSD position. It keeps earning lending yield plus Convex boost. You mint reUSD. The borrow rate is designed around half the collateral yield, floored by documented parameters on the app. That spread is the product. It can invert. Leverage looping is optional and not a beginner step.

## What is Resupply Summer and what is not a benefit?

From 3 August 2026 Convex runs extra RSUP and CVX rewards on Resupply activity. That is a growth campaign: emissions on top of the design. When rounds end, bonus emissions end. We do not treat RSUP tape as a reason to mint or to buy the token. LlamaLend V2 sDOLA/sfrxUSD markets are not Resupply markets.

## Which Resupply risks actually bite?

In June 2025 a new wstUSR market was exploited for about $9.6 million via a donation and oracle-class bug on a thin market. The Insurance Pool took first loss as designed; treasury and partners covered part. New markets can still be dangerous when they are empty. Peg risk on crvUSD, frxUSD and reUSD remains.

## Where is the official Resupply app?

The app we name is resupply.fi. Convex and Yearn are different domains even though they co-built this CDP. LlamaLend V2 sDOLA and sfrxUSD markets are Curve’s, not Resupply’s. Read the June 2025 exploit before you size anything. This page is the decision, not a minting how-to.

## Frequently Asked Questions

- Who built it? Convex and Yearn, launched March 2025. Co-building is provenance, not insurance. Resupply Summer from 3 August 2026 is a Convex-sponsored emissions campaign, not a buy call.
- Has it been exploited? Yes — June 2025, about $9.6 million, wstUSR market. The Insurance Pool absorbed designed first loss. We reversed an earlier clean-record claim on /corrections/.
