Curve Decentralized Exchange: Low‑Slippage Stablecoin Swaps & Liquidity Mining

Discover Curve, the Ethereum‑based decentralized exchange built on StableSwap. Swap stablecoins with fees as low as 0.04%, earn CRV rewards, and provide liquidity for extra DeFi yields.

What Is Curve

Curve is a decentralized exchange designed specifically for stablecoins, allowing users to connect their wallets and perform low‑slippage swaps or provide liquidity to earn CRV.

Curve is built on Ethereum’s StableSwap protocol and focuses on swaps between stablecoins that are pegged to $1. The trading fee can be as low as 0.04 %. Liquidity providers (LPs) who contribute assets to the pools receive a share of the platform fees, extra yields from other DeFi protocols (such as Compound, Yearn, Synthetix, RenBTC, etc.), and the governance token CRV that will be minted in the future.

Security Reminder: Curve’s smart contracts have been audited by Trail of Bits, but an audit does not eliminate all risks. Only commit funds you can afford to lose before participating.

In this article we systematically outline Curve’s core mechanisms and usage pathways, helping readers quickly get started with liquidity provision and low‑slippage swaps while highlighting key safety considerations. Once you master these concepts, you can explore potential high‑yield opportunities within the DeFi ecosystem with greater confidence. The following sections will walk you through each step in a hands‑on manner.

Principle Overview

How Does Curve Achieve Low Slippage?

Curve uses the same AMM (Automated Market Maker) mechanism as Uniswap, but on top of that implements the StableSwap algorithm, which is specifically engineered for stablecoins that are anchored to $1.
Unlike Uniswap’s constant‑product model, the StableSwap curve is smoother, allowing it to maintain extremely low price impact even for large‑volume trades.

How Does Curve Offer Relatively High Annualized Returns?

Trading Fees: The fee generated by each trade on the platform is distributed proportionally among all liquidity providers; higher trading volume translates into higher earnings.
Lending Yield: The pooled assets are automatically deposited into lending protocols such as Compound, generating additional interest.
Governance Token Rewards: CRV tokens will be allocated to liquidity providers in subsequent emissions, further boosting returns.

CRV Token Overview

CRV is Curve’s governance token; holders can participate in proposal voting and parameter adjustments on the platform.

Emission Schedule

Total supply: 3.03 billion CRV
Allocation breakdown
62 % → Liquidity providers
30 % → Stakeholders (linear unlock over 2‑4 years)
3 % → Team members (linear unlock over 2 years)
5 % → Community reserve

During the initial issuance, 1.3 billion CRV (43 % of total) were allocated, of which 5 % were earmarked for early liquidity providers with a 1‑year linear unlock.

The initial liquidity mining program ended at block height 10,627,591 (2020‑08‑10 03:24:29 UTC). Users can check the CRV they have earned at https://www.curve.fi/earlyCRV.

At launch, CRV circulation was 0, with a release rate of roughly 2 million CRV per day, primarily sourced from early holders and subsequent liquidity rewards.

How to Acquire CRV

Regular users can obtain CRV through either of the following two methods:

Providing Liquidity: Deposit assets into Curve’s liquidity pools to earn CRV rewards. (See the “How to Become a Liquidity Provider and Earn CRV” section below.)
Purchasing on Exchanges: Buy CRV directly on the exchanges announced in Curve’s official communications. Keep an eye on Curve’s official channels for the latest list of supported venues.

Scam Alert: As of 2020‑08‑13, CRV had not yet been officially released. Verify the contract address at https://www.curve.fi/contracts to avoid counterfeit tokens.

Note for U.S. users: When buying CRV on a centralized exchange, you must use Binance.US or another U.S.-compliant platform; the global Binance site is not available to U.S. residents.

Tax Reminder: Crypto gains, including any earned CRV, may be taxable in your jurisdiction. Consult a tax professional to understand your reporting obligations.

How to Use Curve for Token‑to‑Token Swaps

Open the imToken app and navigate to Curve’s official site at https://www.curve.fi/

DeFi Project and Tutorial: Step‑by‑step guide to using Curve

In the upper‑right corner of the web page click “Connect Wallet” → “Show More” → select the WalletConnect icon.

Scan the QR code that pops up using imToken to complete the DApp connection and grant permission.

Once connected, choose the token you want to swap from the From field and the token you want to receive in the To field, then enter the amount and click “Sell” to execute the swap. The estimated fee will appear at the bottom of the page.

Advanced options let you customize the liquidity pool, set a maximum slippage tolerance, and adjust the gas (miner) fee.
Slippage is the difference between the execution price and the current market price.

In imToken, tap “Next” to authorize the transaction, confirm, and then select “Continue Sending.”

After the approval and swap succeed, you will see the received token (e.g., DAI → USDT) on the assets page.

How to Become a Liquidity Provider and Earn CRV

Below we use the Compound pool as an example to demonstrate the simplest workflow.

Complete the first three steps of “Using Curve for Token‑to‑Token Swaps” to establish a WalletConnect connection.
On Curve’s Pools page, select the Compound pool.

Click the “Deposit” button at the top of the page to open the deposit interface.

By default, the system will use all the DAI and USDC available in your wallet. If you wish to set custom amounts, uncheck “Use maximum amount of coins available” to switch to manual mode.

In manual mode, the input fields for DAI and USDC turn dark blue, allowing you to type the exact quantities you wish to deposit.

Press “Deposit” and confirm the authorization in imToken. The page will display the amount of LP Token (liquidity receipt) you receive, its price per share, and an estimated gas fee. Recent gas prices have been high; depositing a small amount may see fees erode the expected yield, so calculate beforehand.

After approval, click “Continue Sending” → “Next.” Once both the approval and deposit transactions succeed, you will see the corresponding LP Token (e.g., `cDAI + cUSDC`) in your asset list.

Friendly Reminder: Operational details can vary slightly between different pools; always conduct thorough research before interacting. If you are experienced with liquidity mining and wish to boost returns further, you can redeposit the obtained LP Tokens into secondary incentive platforms such as Balancer. Ensure you fully understand the associated protocols to avoid inadvertent risks.
