What Is Curve?
Curve is one of the most renowned decentralized finance (DeFi) protocols in the crypto space.
Launched in January 2020 as an Automated Market Maker (AMM), Curve aims to provide liquidity for trades while minimizing slippage and transaction fees.
The platform was created by Michael Egorov, founder of NuCypher and a PhD in physics. Egorov identified a critical issue in DeFi: the imperfect peg of stablecoins to their underlying assets (typically the US dollar).
This problem stems from slippage, the difference between an asset’s theoretical price and its actual execution price due to limited liquidity.
Understanding Slippage: An Example
When selling a crypto asset worth $1,000, you’ll sell to the **highest bidder**. On centralized exchanges, bids are often close to the theoretical price (e.g., $999.99).
However, large sell orders risk exhausting demand at that price, forcing trades at lower bids (e.g., $999.98, $999.97). This gap—slippage—grows with order size and shrinks with liquidity.
AMMs like Curve rely on a constant product formula (explained in our Uniswap guide), which can cause inefficiencies when trading stablecoins unless liquidity is abundant.
Egorov solved this with a stablecoin arbitrage program that improves peg stability. Beyond being a DEX, Curve aggregates liquidity for other DeFi apps.
Since 2020, Curve’s liquidity has surged, securing its place among top DeFi platforms.
Key Features of Curve
1. What Is a DeFi Platform?
A DeFi platform is a decentralized financial application built on a blockchain. DeFi emerged in 2017 with Ethereum’s smart contracts, enabling automation of services like trading, lending, and insurance.

2. How Does a DEX Work?
A DEX (Decentralized Exchange) operates without intermediaries. Unlike centralized exchanges (CEXs), DEXs:
- Are non-custodial (users retain control of their keys).
- Use AMM swaps and liquidity pools for trading.
- Reward liquidity providers (LPs) with fees and platform tokens.
Example: Depositing 1 ETH ($3,000) and $3,000 USDT into a pool earns a 20% APY (~$1,200/year), though volatility and impermanent loss affect returns.
3. Integrating Curve via Hot Wallet
To use Curve.fi, connect a wallet like MetaMask. Select the correct network (e.g., Ethereum, Polygon) and ensure you hold the native token for gas fees.
4. Impermanent Loss on Curve
Impermanent loss (IL) occurs when pooled assets diverge in value.
- Low-risk pools: Stablecoin pairs (USDT/USDC) or wrapped assets (WBTC/RenBTC).
- High-risk pools: Volatile pairs (ETH/BTC).
Tip: Deposit during sideways markets to minimize IL.
How Curve Works
1. Supported Networks
Curve operates on:
- Ethereum (including Arbitrum/Optimism)
- Polygon, Fantom, Avalanche
- Gnosis, Moonbeam, Aurora
2. Swapping Tokens
- Select a pool (e.g., Tricrypto2 for ETH/BTC/USDT).
- Choose input/output tokens.
- Adjust slippage and gas priority.
- Execute the swap.
Fees are competitive (~0.04% for stablecoins).
3. Providing Liquidity
- Click Deposit on your chosen pool.
- Select tokens (bonuses for rebalancing underweight assets).
- Stake LP tokens to earn CRV rewards.
APY includes:
- Base APY: Trade fees.
- Rewards APY: CRV incentives.
4. Withdrawing Funds
- Select Withdraw and enter LP share amount.
- Choose output tokens (avoiding swap fees).
- Confirm the transaction.
The CRV Token
CRV is Curve’s governance token. Holders can:
- Vote on protocol upgrades.
- Boost yields by locking CRV as veCRV (up to 4 years for max multipliers).

FAQs
1. Is Curve safe?
Yes, it’s audited and widely trusted. However, DeFi risks (smart contract bugs, IL) persist.
2. Why use Curve over Uniswap?
Curve offers lower fees for stablecoins and similar assets.
3. How to maximize CRV rewards?
Lock CRV long-term and stake LP tokens in high-yield pools.
Final Thoughts
Curve.fi is a secure, high-liquidity platform for earning passive income. While its retro interface lacks intuitiveness, its functionality excels—especially for stablecoin traders.
The CRV token gained relevance during the "Curve Wars," where protocols competed for governance power. Long-term viability depends on DeFi adoption.
