## Summary

Use Curve at curve.finance for large stablecoin and LST swaps, or for crvUSD and LlamaLend if you already understand CDPs. Skip Curve as a first DEX if you are swapping volatile alts — that is Uniswap. Skip gauge voting until you understand Convex. Educational research, not financial advice.

## Should you use Curve?

Yes — for pegged pairs (stables, LSTs) where StableSwap keeps slippage low, and for crvUSD/LlamaLend once you can read an isolated market. Skip it as your first ever swap. Convex is how most people take the CRV boost; you do not need to lock CRV yourself.

DeFiLlama snapshot 2026-08-27: about $1.3 billion TVL for this listing. That is lockup, not a safety rating — re-check the live figure before you size anything.

## What is Curve and how does StableSwap work?

Curve’s StableSwap concentrates liquidity near a peg, which is why a large USDC/USDT swap often prints less slippage than a general AMM. That edge dies if the peg breaks. crvUSD is Curve’s CDP stablecoin with LLAMMA soft liquidation. LlamaLend V2 is isolated lending — Inverse sDOLA and Frax sfrxUSD were early Ethereum V2 markets in July 2026.

## Curve vs Uniswap vs Convex vs Resupply — which should you use?

Curve for pegged liquidity. Uniswap for everything else. Convex to take max boost without a four-year CRV lock. Resupply to mint reUSD against Curve Lend or Fraxlend positions — a CDP, not a swap. They share gauges; they do not share one risk engine.

## Which Curve risks actually bite?

Peg breaks in a ‘stable’ pool, gauge emissions leaving your LP, and smart-contract risk — including 2023 Vyper-related exploits on some older pools. New LlamaLend markets start with caps at zero until governance raises them. Read the pool version before you LP.

## Where is the official Curve app?

The app we name is curve.finance. Confirm the pool version and tokens before you LP. Convex is a different domain. Resupply is resupply.fi. This page is which Curve surface you actually wanted — swap, crvUSD, LlamaLend — not a first-wallet tutorial.

## Frequently Asked Questions

- What is Curve? A DEX specialised in pegged assets, plus crvUSD and LlamaLend, at curve.finance. StableSwap keeps slippage low near a peg and loses that edge if the peg breaks.
- Do I need to lock CRV? No. Convex pools veCRV and passes boost to depositors. Lock CRV yourself only if you want personal veCRV and can wait years.
- Is Resupply part of Curve? No. Resupply is a separate CDP that uses Curve Lend and Fraxlend collateral. LlamaLend V2 is Curve’s isolated lending — also not Resupply.
- Does this page recommend CRV? No. Educational research only. We do not recommend LPing, locking CRV, or buying the token.
