The problem CosmosPool solves

CosmosPool is a decentralized liquidity provision system designed to simplify the process of providing liquidity to Concentrated Liquidity Market Makers (CLMMs) like Uniswap V3. Traditional CLMMs require users to deposit both tokens in a trading pair within a specific price range, which can be complex and inaccessible for many users. CosmosPool solves this by enabling single-sided deposits, automatically matching users with complementary deposits, and managing liquidity provision on their behalf.

The system is built on Unichain, a blockchain optimized for DeFi applications, and integrates with Uniswap V3 for liquidity calculations and pool interactions. By abstracting away the technical complexities of dual-sided deposits and price range management, CosmosPool makes liquidity provision more accessible, efficient, and user-friendly.

The project architecture and development process

Core Functionality:

1.Single-Sided Deposits:

Users can deposit a single token (e.g., WETH or USDC) into the LiquidityManager smart contract.

The contract tracks deposits and matches users with complementary providers.

2.Automated Matching:

The system matches users with complementary deposits (e.g., a WETH depositor with a USDC depositor).

3.Liquidity Provision:
The matched tokens are deposited into a Uniswap V3-style pool on Unichain.

Uniswap's concentrated liquidity formula is used to calculate the optimal liquidity provision.

Key Implementation Details:

Smart Contracts:

LiquidityManager.sol:

Handles deposits, matching, and withdrawals.

Emits events (UsdcDeposited, WethDeposited, LiquidityMatched) to track user interactions.

Integrates with Uniswap's NonfungiblePositionManager for liquidity provision.

MockNonFungibleToken.sol:

Simulates Uniswap's position manager for testing.

Includes functions like mint and withdrawTokens to mimic real-world behavior.

Uniswap Integration:

The system uses Uniswap's concentrated liquidity formula to calculate optimal liquidity

Product Integrations

Uniswap, Unichain, Hardhat, Web3.js, Ethers.js, Coin Gecko API

Key differentiators and uniqueness of the project

Key Features:

Single-Sided Deposits:

Users can deposit a single token (e.g., WETH or USDC) without needing to hold both assets in a trading pair.

Automated Matching:
The system matches users with complementary deposits, ensuring balanced liquidity provision.

Uniswap Integration:
Leverages Uniswap's proven liquidity formulas and infrastructure for optimal liquidity provision.

Mock Testing Environment:
Includes a mock position manager for safe and efficient testing without deploying to mainnet.

Dynamic Reward Distribution:
Rewards are distributed based on a fixed ratio (e.g., 60/40 favoring volatile token providers).

Unique Aspects:
Simplified User Experience: By abstracting away the complexities of dual-sided deposits and price range management, CosmosPool makes liquidity provision accessible to a wider audience.

Unichain Deployment: Optimized for Unichain, a blockchain designed for DeFi applications, ensuring high performance and low transaction costs.

Scalability: Designed to support additional tokens and integrate with other DEXs in the future.

Comparison with Similar Projects:

Unlike traditional CLMMs, CosmosPool eliminates the need for users to hold both tokens in a trading pair.

Compared to other single-sided liquidity solutions, CosmosPool integrates directly with Uniswap V3, leveraging its proven infrastructure and liquidity formulas.

The inclusion of a mock testing environment ensures a safer and more efficient development process.

Trade-offs and shortcuts while building

Mock Position Manager:

Used a mock implementation of Uniswap's position manager for testing, which lacks some real-world complexities but allows for safe and efficient development.

Hardcoded Price Range:
Initially, the price range is fixed at ±10% of the current price for simplicity. This will be expanded to allow customizable ranges in future updates.
