提案名称：奖励参与流动性迁移的用户，并重新分配矿池权重

替换提案：无
2 、摘要
本提案中，核心开发团队建议奖励参与第一次流动性迁移的用户，并向社区阐明此次奖励的资金来源。同时，核心开发团队建议在借贷协议上线后，重新分配矿池权重，并阐述具体的执行方案。
3 、动机
借贷协议是 WePiggy 最为核心的部分，而支撑借贷业务正常运行的正是流动性。奖励用户的流动性迁移行为有助于引导用户将资金从其他借贷协议转移到 WePiggy 协议，建立最初的信任关系。为了借贷协议的可持续发展，应该重新分配矿池权重，让代币经济激励与借贷协议的业务发展直接挂钩。
4 、正文
4.1 行动1：WePiggy 第一次流动性迁移奖励
在 WePiggy 之前，目前 DeFi 市场上第二大 DEX，流动性迁移的首创者 Sushiswap 也曾在执行流动性迁移时，额外发放了部分代币奖励，并且有效促成了整个迁移过程的顺利执行。但是，Sushiswap 的迁移奖励，完全以资金体量作为衡量标准。这对资金体量小却一直支持项目发展的用户是不够公平的。
WePiggy 将在执行流动性迁移时，对所有用户进行全面的数据分析，提出更为公平合理的奖励方案，照顾到不同资金体量用户的参与度。
在此，核心开发团队建议从 WePiggy 基金会的 “资源拓展” 部分拨出 10,000 个 WPC，用于奖励参与首次流动性迁移的用户。**截至本提案发出之时，智能合约分配给“资源拓展”的 WPC 约有 3.5 万个，可以满足本次奖励所需的代币数量。
4.2 行动2：WePiggy 流动性挖矿计划的矿池权重调整
1 . 借贷协议上线之后，WePiggy 的流动性挖矿应当优先激励借贷业务规模的扩张。因此，在完成第一次流动性迁移后，当前所有矿池应该暂停产出 WPC。
2 . 借贷协议上线时，将首先支持 WBTC、ETH、DAI、USDT，以及 USDC 这五种借贷资产对应的 pToken* 参与流动性挖矿，重点激励继续为 WePiggy 协议提供流动性的存币用户。
3 . 保留空投奖励储备池（Airdrop）。该矿池权重始终为 1000，用于在 WPC 正式上线交易的第一天，空投奖励给曾经使用过 WePiggy 借贷协议的忠实用户。
4 . 按照 WePiggy 协议的创世文章约定，YFII 将在 Chainlink 支持喂价（预计 2021 年 1 月中旬）后，无需提案投票，立即作为借贷资产上线，并启动对应的 pToken 矿池。
5 . 其他资产将在借贷协议上线并稳定运行一周后，以提案方式由社区投票决定是否可作为借贷资产加入到协议中，并重新启动相应矿池。上线新资产如果处理不当，将会为整个借贷协议引入难以预测的风险。届时，核心开发团队将向社区提交一个完整的借贷资产风险评估框架，帮助社区更好地判断某种资产加入到协议中可能引入的各种风险。
当前各个矿池权重如下：
| 矿池名 | Airdrop | HBTC | SAKE | QUSD | UNI | YFII | cWBTC | cETH | cDAI | cUSDT | cUSDC | aWBTC | aETH | aDAI | aUSDT | aUSDC |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 权重分 | 1000 | 200 | 200 | 334 | 333 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 |
借贷协议上线之后，各个矿池权重调整如下：
| 矿池名 | pETH | pWBTC | pDAI | pUSDT | pUSDC | Airdrop |
|---|---|---|---|---|---|---|
| 权重分 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 |
*pToken 实质即是向 WePiggy 提供资金的所有权证明，用户将某种资产存入 WePiggy 的借贷协议当中，即可获得相应的pToken。

1、支持行动 1 和行动 2
2、支持行动 1，但不支持行动 2
3、不支持行动 1，但支持行动 2

WIP5: Reward users who participate in liquidity migration and redistribute the weight of the mining pool
1. Preamble
Proposal Number: WIP5
Proposal Title: Reward users who participate in liquidity migration and redistribute the weight of the mining pool
Proposal Author(s): Core Devs
Related Proposals / Dependencies: N/A
Replacement Proposal / Replaces: N/A
2. Abstract
In this proposal, the core development team proposes to reward users who participate in the first liquidity migration and clarifies the source of funding for this reward to the community.
At the same time, the core development team proposes to redistribute the weight of the mining pool after the lending protocol goes live, and explains the specific plan.
3. Motivation
Lending protocol is the core part of the WePiggy protocol, and it is liquidity that supports the normal operation of lending business. Rewarding users who participate in the first liquidity migration helps guide users to transfer their funds from other lending protocols to the WePiggy protocol and establish an initial trust relationship.
For the sustainable development of the lending protocol, the weight of the mining pool should be redistributed so that the token economic incentives are directly linked to the business development of the lending protocol.
4. Specification
4.1 Action 1: Reward users who participate in liquidity migration
Before WePiggy, Sushiswap, the pioneer of liquidity migration and the second largest DEX in the current DeFi market, also gave out some token rewards when carrying out liquidity migration, and effectively facilitated the smooth execution of the whole migration process.
However, Sushiswap’s migration rewards are distributed entirely based on the amount of funds. This is not fair enough for users who have been supporting Sushiswap’s development with small funds.
WePiggy will conduct a comprehensive data analysis of all users, and propose a fairer and more reasonable rewarding plan, taking into account the participation of users with different amounts of funds.
Here, the core development team proposes to allocate 10,000 WPC tokens from the " business development " part of the WePiggy Foundation to reward users who participate in the first liquidity migration.
As of the time this proposal is issued, there are approximately 35,000 WPC tokens have been distributed to WePiggy foundation for "business development ". So, the number of tokens required for this reward (10,000 WPC tokens in totoal) can be met.
4.2 Action 2: Redistribute the weight of the mining pool
1 . After the launch of lending protocol, WePiggy’s liquidity mining should give priority to the expansion of the lending business scale. Therefore, after the first liquidity migration was completed, the WPC output from all current mining pools should be suspended.
2 . When the lending protocol goes live, the pTokens* corresponding to the 5 crypto assets of WBTC, ETH, DAI, USDT, and USDC will first be supported to participate in the new liquidity mining program, to focus on incentivizing deposit users who continue to provide liquidity for the WePiggy protocol.
3 . Keep the airdrop reward reserve pool (Airdrop), and the weight is still 1000. It is used to reward loyal users who have used WePiggy protocol by airdrops according to certain rules on the first day when WPC tokens are officially unlocked and traded.
4 . According to WePiggy’s genesis article, YFII will be added into WePiggy’s lending protocol as a lending asset and the corresponding pToken mining pool will be added as well, after Chainlink provides the price feed of YFII (expected in mid-January 2021).
5 . Other assets will be added to the lending protocol through a proposal vote by the community after the lending protocol goes online and runs stably for a week. At that time, the core development team will submit a complete lending asset risk assessment framework to the community to help the community better evaluate the various risks that may be introduced by adding a certain asset to the protocol.
Currently, WePiggy has a total of 16 mining pools, and their weights are as follows:
| Pool | Airdrop | HBTC | SAKE | QUSD | UNI | YFII | cWBTC | cETH | cDAI | cUSDT | cUSDC | aWBTC | aETH | aDAI | aUSDT | aUSDC |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Weight | 1000 | 200 | 200 | 334 | 333 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 |
After the lending protocol goes live, the weights of WePiggy’s mining pools will be adjusted:
| Pool | pETH | pWBTC | pDAI | pUSDT | pUSDC | Airdrop |
|---|---|---|---|---|---|---|
| Weight | 1000 | 1000 | 1000 | 1000 | 1000 | 1000 |
*pTokens are essentially tokenized deposit receipts of WePiggy.
You can get pTokens by depositing your crypto assets in WePiggy’s lending market.
