Description

Mama Exchange is a decentralized exchange (DEX) built on the Flow blockchain that offers many type of trading options: Automated Market Maker (AMM) and Spot Trading and have a plan to open other trading types like Margin Trading, Future Trading.

Inspiration

Uniswap V3(Concentrated liquidity)

Concentrated liquidity acts as a mechanism that lets the market decide the distribution of liquidity. Liquidity Providers can allocate their liquidity to custom price ranges, ensuring higher efficiency of liquidity for the pool and a higher reward for Liquidity providers.

The efficiency of liquidity: Statistics data also shows UniswapV3 has liquidity of 2.4B and a volume is 8.6B per day with the volume being four times greater than liquidity. In comparison, UniswapV2 has liquidity of 786M but the volume is only 98.75M, which is only 1/7 times compared to liquidity. Check the data here.

More reward: Liquidity providers on V3 receive a higher Annual Percentage Rate (APR) compared with V2. For instance, Users provide liquidity for ETH/USDC with a price between 1000USD/ETH to 2000 USD/ETH can receive up to 96% APR. This is an incredibly high reward. Check the data here.

Centralized Exchange

CEX(Centralized Exchange) provides various of trading including Spot Trading(Market Trading, Limit Trading), Margin Trading, and Future Trading which are very convenient for users. Additionally, CEX often offers a range of trading tools, such as charts, technical indicators, and order books, to help users make the right trading decisions. By incorporating these tools into DEX, we can encourage greater user participation in decentralized finance (DeFi) on Flow.

However, users on CEX need to deposit their funds, and many now desire greater control over their funds. By building a DEX on Flow, we can empower users to maintain full control over their assets while enjoying the convenience of CEX's trading tools.

Problem statement

• There is no AMM Concentrated liquidity on Flow.
• There is no Spot Trading, Margin Trading, Future Trading on Flow
• AFAIK, There are no DEX on flow that provides trading tools: Charts, technical indicators and order books ... like a CEX

Proposed solution

Here is summary MamaEx features compared with Blocto and Increment

Features	MamaEX	Blocto	Increment
Trading types	AMM (Concentrated liquidity), Spot Trading	AMM	AMM
Capital Efficiency	AMM (Concentrated liquidity)	Basic	Basic
Pool fee	Different pool fee for token pairs	No	No
Oracle Price	Provides history up to 10 days	No	N/A
NFT Generation	Available for Liquidity Providers	No	No
Trading tools	Charts, technical indicators, and order books, Swap	Basic	Good
Order types	Market Order, Limit Order	No	No
Future Trading	Planned	No	No
Margin Trading	Planned	No	No

Impact

• Spot Trading: (Market Order, Limit Order) increases the diversity of trading options available on the Flow network
• AMM (Concentrated liquidity): Increases the efficiency of capital usage for liquidity providers, resulting in more liquidity being available on the network.
• Pool fee: Provides more flexibility for liquidity providers to choose the most appropriate pool fee for different token pairs, potentially attracting more liquidity to the network.
• Oracle Price: Provides history up to 10 days that allows other DeFi dApps to build on top of MamaEX's Oracle Price, potentially attracting more developers and users to the Flow network.
• NFT Generation for liquidity providers: Flow is one of the best NFT blockchain network. This is another reason why user need an NFT on their wallet.
• Trading tools: Charts, technical indicators, and order books that improves the user experience for traders and makes the Flow network more competitive with centralized trading platform.
