Multi-pool mechanism

Using a multi-pool strategy, independent pools are built for each NFT series, and the creation of the pool is governed by the DAO method. Users can make proposals in the community to establish an NFT pool for this series.

Liquidity providers choose at least one pool to provide liquidity. The price currently adopts the floor price method (the agreement will adopt a more effective price feeding method after a better price mechanism matures). While providing liquidity, apart from tokens, NFT holders need to submit a corresponding interest rate and collateral rate (the higher risk of the NFT, the lower collateral rate and the higher interest rate). Each NFT pool consists of multiple interest rate, collateral rate and token pairs; Each pool can then be expressed as：

$P=\sum_{i=1}^n x_i$ $x_i$ represents a single token pair $x_i=(m,c,r)$ m represents the number of tokens, c represents the collateral rate, r represents the interest rate
