Moai Finance 2.0

Moai Finance 2.0 utilizes Uniswap V3 to provide concentrated and efficient liquidity.

Concentrated Liquidity Concept

What is Concentrated Liquidity?

Concentrated Liquidity allows liquidity providers to:

• Specify precise price ranges for token pairs

• Maximize capital efficiency

• Provide liquidity more strategically compared to traditional AMMs

Key Characteristics

1. Customizable Liquidity Ranges

   • Providers can select specific price intervals

   • Liquidity is concentrated within chosen price bounds

   • More capital deployed near current market price

2. Price Ticks

   • Discrete price points within the liquidity range

   • Enables granular liquidity positioning

   • Similar to order book price levels

3. Active Tick

   • The current price tick where trading occurs

   • Liquidity is most concentrated and active at this point

Technical Implementation

Smart Contract Modifications

solidityCopy// Core Contract Interfaces
contract UniswapV3Pool {
    // Tracking liquidity properties
    uint128 public liquidity;
    uint128 public liquidityStaked;
    
    // Reward and fee tracking
    uint256 public rewardGrowth;
    uint256 public feeGrowth0;
    uint256 public feeGrowth1;
}

contract NonfungiblePositionManager {
    // Liquidity Position Management
    function mint(...) external returns (uint256 tokenId);
    function stake(uint256 tokenId, uint128 liquidityAmount) external;
    function unstake(uint256 tokenId, uint128 liquidityAmount) external;
    
    // Position Information Retrieval
    function positions(uint256 tokenId) external view returns (..., uint128 liquidity, ...);
    function positions2(uint256 tokenId) external view returns (uint128 liquidityStaked, ...);
}

Interaction Workflow

1. Liquidity Provision

   solidityCopy// Provide liquidity to a specific range
   (uint256 tokenId,,) = nft.mint({
       token0: address,
       token1: address,
       fee: uint24,
       tickLower: int24,
       tickUpper: int24,
       amount0Desired: uint256,
       amount1Desired: uint256
   });

2. Staking Liquidity

   solidityCopy// Stake a portion of liquidity
   uint128 liquidityToStake = calculateStakeAmount();
   nft.stake(tokenId, liquidityToStake);

3. Unstaking Liquidity

   solidityCopy// Unstake liquidity
   uint128 liquidityToUnstake = calculateUnstakeAmount();
   nft.unstake(tokenId, liquidityToUnstake);

Unique Features

• Flexible Staking: Partial liquidity can be staked

• Reward Tracking: Continuous Moai rewards for staked positions

• Fee Distribution: Trading fees distributed to Moai stakers

Important Considerations

• Transferring position NFT automatically un-stakes all liquidity

• Staking amount cannot exceed available unstaked liquidity

• Carefully select price ranges to optimize returns

Potential Strategies

• Narrow Range: High capital efficiency, more risk

• Wide Range: Lower capital efficiency, more stability

• Dynamic Range Adjustment: Actively manage liquidity position
