The problem Liquor solves

Centralized exchanges such as WazirX, Coinbase, Binance, etc. have various drawbacks over a decentralized exchange.
A similar protocol called Centralized Exchanges (CEX) is available in centralized wallets for investing in cryptocurrencies that charge higher transactional charges to liquefy and transfer. The involvement of utility tokens causes a lot of inefficiencies.
Centralized Exchanges are always under the radar of governments and regulatory entities. For that reason, the users of such exchanges should pass through the different types of identity verification before starting to use such platforms.
Users of centralized exchanges are not the true owner of their assets. If you decide to hold your assets in these exchanges, you have to be aware that the exchange is the true owner of your private keys, and you choose to trust them with that.

As you see, the clear winner is DEX. This may sound strange, primarily because of the popularity of centralized exchanges between crypto users.
However, these days, the Decentralized Exchange model is gaining more momentum and popularity because:

1. Decentralized Exchanges offer more coins/tokens to trade.
2. Decentralized Exchanges do not need any KYC or similar user identification processes.
3. Decentralized Exchanges do not own users’ assets and are less likely to crash.
4. Decentralized Exchanges takes very less fee compare to CEX

Challenges we ran into

Being a team of newbies in Web 3, we faced various challenges while creating different smart contracts

1. At first we faced issues while connecting the local host to metamask and processing of payments on ETH Network.
2. Earlier we were not able to swap different coins but later on we improvised our prototype to that extent through which we were able to swap around more than 200 different types of coins.
