TradingPool

TradingPool is at the heart of the TRADE module. It defines a liquidity pool where NFTs and a designated token (e.g., SUI or another fungible token) interact.

Key Fields:

• id: A unique identifier for the pool.

• collection_id: Identifies which ART20 collection the NFTs belong to.

• nft_reserve: The count of NFTs held in the pool.

• token_reserve: A balance of the fungible tokens paired with the NFTs.

• lp_supply: A supply object representing the total amount of LP tokens minted.

• lp_shares: Balance of LP tokens representing liquidity provider shares.

• fee_percent: The fee charged on trades, distributed among LPs and possibly the pool creator.

• min_price / max_price: Bounds to ensure pricing remains within a certain range.

• is_active: Indicates if the pool is currently operational.

• accumulated_fees / contract_owner_accumulated_fees: Track accumulated and undistributed fees.

• nft_holdings: A table storing the NFTs pooled within the TradingPool.

• last_trade_price: The most recent trade’s price, aiding in historical data and price impact calculations.

Role:
