What is Curve?
Curve Finance is the leading decentralized exchange for stablecoin and pegged asset trading, known for its extremely low slippage and deep liquidity. Launched in 2020 by Michael Egorov, Curve introduced the StableSwap algorithm, a specialized AMM designed specifically for assets that should trade at similar prices.
With over $2 billion in TVL, Curve serves as critical infrastructure for DeFi, enabling efficient stablecoin swaps and providing deep liquidity for liquid staking tokens like stETH and rETH. The protocol processes billions in monthly volume while maintaining slippage often 10x lower than traditional AMMs.
Curve pioneered the vote-escrow (ve) tokenomics model, where users lock CRV tokens to receive veCRV, granting voting power, boosted rewards, and protocol fee sharing. This model has been widely copied and influenced governance design across DeFi.
Key Metrics
- Total Value Locked: $2B+ across all pools
- Networks: Ethereum, Arbitrum, Optimism, Polygon, Avalanche, Base
- Trading Volume: Billions of dollars monthly
- Total Pools: 100+ across all chains
- Security Audits: Multiple audits from Trail of Bits, Quantstamp
- Governance: veCRV holders control gauge weights and protocol parameters
How Curve Works
The StableSwap Algorithm
Unlike standard AMMs that use x*y=k, Curve uses a specialized bonding curve optimized for assets with similar prices:
- Low Slippage: Trade millions with minimal price impact
- Concentrated Liquidity: Capital efficiency for pegged assets
- Dynamic Fees: Adjust based on pool imbalance
- Pegged Assets: Best for stablecoins, wrapped tokens, and LSTs
The veCRV System
CRV tokenomics center on vote-escrow locking:
- Lock CRV: Lock for 1 week to 4 years to receive veCRV
- Longer Lock = More Power: 1 CRV locked for 4 years = 1 veCRV
- Gauge Voting: Direct CRV emissions to your preferred pools
- Boosted Rewards: Up to 2.5x higher LP rewards with veCRV
- Fee Sharing: Earn 50% of protocol trading fees
Curve Pools
Curve offers several pool types:
- StableSwap Pools: For stablecoins (USDC/USDT/DAI)
- Crypto Pools: For volatile asset pairs using Curve V2
- Tricrypto Pools: Multi-asset pools for major tokens
- Factory Pools: Permissionlessly created pools

Understanding Curve yields requires tracking base APY, CRV rewards, and boost levels across many pools. Fensory simplifies this by aggregating all Curve opportunities and calculating your effective yield based on your veCRV balance.
Curve Fee Structure
| Fee Type | Amount | Description |
|---|---|---|
| . . . . . | . . . . | . . . . . . - |
| Swap Fee | 0.04% | Base fee on trades |
| Admin Fee | 50% of swap fee | Goes to veCRV holders |
| Deposit | 0% | No fee to provide liquidity |
| Withdraw | 0-0.5% | Small fee if imbalanced |
Current Yields (Examples)
| Pool | Base APY | CRV APY | Total |
|---|---|---|---|
| . . . | . . . . . | . . . . - | . . . - |
| 3pool (DAI/USDC/USDT) | 1-3% | 2-5% | 3-8% |
| stETH/ETH | 2-4% | 1-3% | 3-7% |
| Tricrypto | 5-15% | 3-10% | 8-25% |
Risks and Considerations
- Smart Contract Risk: Complex protocol with multiple components
- Impermanent Loss: Less risk for pegged assets, more for Crypto pools
- Depeg Risk: If a stablecoin depegs, pool value can drop significantly
- veCRV Lock Risk: Locked CRV cannot be withdrawn until lock expires
- Governance Risk: veCRV holders control emissions and parameters

Frequently Asked Questions
What is impermanent loss on Curve?For stablecoin pools, impermanent loss is minimal because assets maintain similar prices. For Crypto pools (volatile pairs), IL risk is higher but offset by trading fees. The real risk is depeg events.
How does veCRV boosting work?With veCRV, you can boost your LP rewards up to 2.5x. The boost depends on your veCRV balance relative to the total and your LP position size. Use boost calculators to optimize.
Should I lock CRV for veCRV?Locking provides governance power, fee sharing, and boosted rewards. However, locks are irreversible until expiry. If you are a long-term Curve user, locking makes sense. Short-term users may prefer liquid alternatives like cvxCRV.
How do I track my Curve positions?Between multiple pools, chains, and boost calculations, Curve accounting is complex. Fensory tracks all your Curve positions and calculates real yields including boosts.
