In this article, Coin98 will guide you on how to use Curve Finance, including swap, add liquidity, and vote on governance. Let's get started!

The DeFi world is rapidly expanding to the extent that can lead to mass adoption in our lives. Curve Finance has become a phenomenon in 2021 since BTC ATH breakout. But getting started with Curve isn’t easy because the UI is somewhat really exotic. No worries, this article will show you how to use Curve Finance and its services.

Curve Finance Overview

Curve Finance is now a leading Decentralized Exchange on the Ethereum blockchain that specializes in trading stablecoins such as USDT, USDC, DAI, etc. In particular, it’s on top of the DeFi world in terms of TVL with more than $12 billion dollars locked.

Curve's TVL

In short, Curve Finance calculates the swapping price based on an AMM protocol to reduce slippage instead of using a traditional Orderbook. The CRV token has several use cases that incentivize the demand. For example, users can provide their tokens in Liquidity Pools in order to earn rewards from others’ trades. Furthermore, Curve Finance improvised the protocol to optimally boost the yield in pools up to x2.5.

Additionally, CRV tokens are also utilized in the governance mechanism that contributes to decentralization. As a result, Curve Finance is the most preferred exchange for trading stablecoins because it is in favor of stability and high liquidity.

Create an Ethereum Wallet on Coin98 Wallet

Users can create an ERC-20 wallet or import an existing wallet from another platform into the Coin98 Wallet.

Since Curve Finance is built on the Ethereum blockchain, users need to create or import Ethereum Wallet to use Curve’s services. 

If users are currently using Coin98 Wallet, they can re-import their multichain wallet to automatically update their own Ethereum (ERC-20) wallet as well as other new wallets available in the latest version!

Remember to transfer all assets to the ERC-20 wallet before trading. 

In case users accidentally transfer money to the TRC20, BEP20, or SPL wallets, Coin98 Wallet’s Cross-chain Bridge function will support converting tokens to ERC20 directly in the app instead of transferring them back to Binance and then withdrawing ERC20 tokens to their wallet. This is one of Coin98 Wallet's technological improvements to make it easier to trade on Curve Finance.

Preparing ETH for the gas fee

Curve Finance uses ETH for gas fee. Therefore, in order to trade on Curve Finance, users must have ETH in their wallets.

Currently, Curve Finance offers daily users a 0.04% fee of the total trading value for stablecoin trades. And the trading fees go to Liquidity Providers.

To become fully decentralized, Curve Finance has a voting system that allows CRV holders to vote on multiple parameter changes and DAO proposals.

Please go to this address to do so:

Step 2: Enter the amount of CRV you want to lock. It is required to have at least 2500 veCRV to be able to create a DAO proposal. However, if you only want to vote, there’s no need to have that much veCRV.

Step 3: Choose lock time. On average, you can lock 1,000 CRV for a year to have a 250 veCRV voting weight.

Step 4: Choose a proposal to vote for.

Step 5: Click Yes if you are in favor of the proposal and confirm your transaction.
