# Insurance pool

### Insurance pool

### 1. Insurance Pool

The insurance pool contains multiple groups of independent capital pools, such as USDP-AUSDT, PETH-AETH, etc., which do not affect each other.

### 2. Insurance Pool Functionality

The PUMO insurance pool has three functions:

1）Insurance. The policy-holder can stake the underlying assets into the insurance pool to obtain the corresponding insurance share token to earn assets swap fees and liquidation profits, but also need to bear the risk of liquidation losses. When an insurance is redeemed, the underlying or synthetic assets are redeemed in accordance with the insurance share \* net value.（The underlying asset is redeemed first, and the synthetic asset can be redeemed if the underlying asset is insufficient.）

2）Asset Swap. The swap between underlying asset and the synthetic asset.

3）Liquidation. when the liquidator repay the synthetic assets into the insurance pool, the insurance pool will need to destroy the synthetic assets corresponding to its liquidated debts. If the synthetic asset  that liquidator pays back is larger than the debt, the insurance pool remains profitable. Otherwise the insurance pool will incur a loss, and it will be included in the negative account.

### 3. New Insurance Pool

When a new insurance pool is created for a native asset and a synthetic asset, an insurance pool LP token and a synthetic asset token need to be created. For example, when the AETH-PETH insurance pool is added, the synthetic asset PETH needs to be minted and the AETH-PETH insurance pool share LP token is created. PUMO V1.0 will initially support aUSDT-USDP insurance pool.

### 4. 注入保险

作为投保人（LP），可向保险池注入原生资产（如aUSDT等），以赚取保险池收益（包括清算收益、稳定费收益和资产兑换手续费等），同时也需要承担清算亏损风险。

### 5. 赎回保险

投保人（LP）在向保险池注入原生资产（投保）后，可根据持有的保险池份额LP代币赎回注入的原生资产。

#### 1）可赎回份额

* 若当前日期不是指定赎回日，则可赎回份额为0；
* 若当前已解冻的份额\*净值 ≤ 保险池净资产，则可赎回已解冻的份额数量；
* 若当前已解冻的份额\*净值 ≥ 保险池净资产，则最大可赎回份额为保险池净资产数量/净值。

#### 2）指定日期赎回

赎回保险只能在指定赎回日进行操作，每90天一次，按照净值赎回。

* 用户只有在指定日期才可赎回保险，每90天为下一个赎回日，初始赎回日为配置值；
* 每个份额在获取时都会在新增系统总冻结的份额数量，并在成功注入保险池后，开始计时，每个份额冻结时间要求 ≥ 90天，并且在指定日期才能进行赎回。
