WIP37:下架部分资产以保障协议安全性 / Delisting Some Assets to Ensure the Security of the Protocol

1 、前言

提案编号:WIP37
提案名称:下架部分资产以保障协议安全性
提案作者:Core Devs
有关提案:无
替换提案:无

2 、摘要

本提案中,核心开发团队建议下架各链上的部分资产,并对标准以及动机进行了详细的阐述。

3 、动机

近期,由于市场趋于熊市,一部分资产在某些链上的交易流动性越来越差,走向枯竭,已经与最初上线时的情况有较大的差异;一部分资产,因其开发团队以及社区进入不活跃状态,资产规模以及用户量大幅度减少。

不仅如此,还有一些其它的安全风险可能发生,诸如:喂价机制,大规模应用状况等因素。

有鉴于此,核心开发团队提议在某些链上下架部分资产,以预防可能出现的安全事故以及清算危机,保障用户的资产安全,保障协议的健康发展,尽一切努力避免黑天鹅的发生。

4 、正文

4.1 下架标准

与 WIP 34 中阐述的下架长尾资产的原因略有不同,即便是这些资产的市值仍然处于较高水平,或者是稳定币资产,为了更好的保障协议的安全,核心开发团队提议根据以下标准对部分资产进行下架处理:

1、该资产在某一条链上的 DEX 中的交易流动性太小,意味着难以在价格大幅度波动时,满足大规模清算需求
2 、该资产的开发团队以及社区已经处于不活跃状态,意味着资产的成长性有限,甚至可能发生大规模的代币抛售
3 、该资产在某一条链上的 WePiggy 中的存款规模小,其它借贷协议中也没有大规模的存款,意味着持有者或使用场景有限

4.2 下架涉及资产

根据 4.1 所列之标准,将下架以下资产:

网络1:ETH
下架资产:RAI

网络2:OKC
下架资产:ETCK、SUSHIK、UNIK、WBTCK、FILK、DOTK

网络3:BSC
下架资产:UNI

网络4:HECO
下架资产:HBCH、HDOT、HLTC、UNI、HFIL

网络5:Polygon
下架资产:SUSHI

4.3 下架流程

第一步:设置该市场的 WPC 分配奖励为 0 WPC/区块

这将有助于推动相关用户取款、还款。

第二步:关闭该市场的存/借功能

关闭市场的存款/借款功能,取款以及还款功能不受影响;借贷协议前端将折叠下架资产,但是用户可以在“我的资产”页面找到下架资产,直至用户没有存入或借取任何该资产。

第三步:准备金率调整为:100%

准备金率提升至 100%,意味着用户的存款将不会有任何的存款收益,以推动相关用户取款。同时,用户取款会推高借款利率,如此将会推动相关用户还款。

第四步:提案通过 3 周后,将该资产的最大质押率调整为:0%

提案通过 3 周内,将尽量通知用户偿还对其它资产的借款,取消该资产作为质押物;

若期间用户已经没有质押该资产进行借款的行为,将立即完成质押率调整;

3 周后,一次性将质押率调整为 0%。

免责声明: 因最大质押率调整造成的清算,属于市场行为,协议没有补偿义务

WIP37:Delisting Some Assets to Ensure the Security of the Protocol

1. Preamble

Proposal Number: WIP37
Proposal Title: Delisting Some Assets to Ensure the Security of the Protocol
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 delist some assets on some chains, and elaborates on the criteria and motivations.

3. Motivation

Recently, as the market tends to be in a bear market, the liquidity of some assets on certain chains is getting worse and worse, which is quite different from the situation when they were originally launched; for some assets, their development teams and communities have become inactive, and the scale of assets and the number of users have been greatly reduced.

Not only that, there are some other security risks that may occur, such as: price feeding mechanism, mass adoption conditions and other factors.

In view of this, the core development team proposes to delist some assets on certain chains to prevent possible security incidents and liquidation crises, ensure the safety of users’ assets, ensure the healthy development of the protocol, and make every effort to avoid black swan events.

4. Specification

4.1 Delisting Criteria

The core development team proposes to delist some assets according to the following criteria:

1 . The trading liquidity of the asset in the DEX on a certain chain is too small, which means that it is difficult to meet the large-scale liquidation demand when the price fluctuates greatly

2 . The development team and community of the asset have been inactive, which means that the growth of the asset is limited, and even large-scale token selling may occur

3 . The deposit market size of the asset in WePiggy on a certain chain is small, and there are no large-scale deposits in other lending protocols, which means that the market demand for the asset is very limited

4.2 Assets Will Be Delisted This Time

Based on the criteria set out in 4.1, the following assets will be delisted:

Network 1: Ethereum
Asset: RAI

Network 2: OKC
Assets: ETCK, SUSHIK, UNIK, WBTCK, FILK, DOTK

Network 3: BSC
Assets: UNI

Network 4: HECO
Assets: HBCH, HDOT, HLTC, UNI, HFIL

Network 5: Polygon
Asset: SUSHI

4.3 Standard Operating Procedure (SOP) of Delisting

Step 1: Set the WPC distribution reward of this market to 0 WPC/block

This will help push the relevant users to withdraw and repay their funds as soon as possible.

Step 2: Disable the deposit/borrow function of the market

Disable the deposit/borrow function of the market, the withdraw/repay functions will not be affected; the delisted assets will be collapsed in WePiggy’s App, but users can easily find the delisted assets in “My Assets” until the user does not deposit or borrow any such assets.

Step 3: Adjust the reserve factor to 100%

Increasing the reserve factor to 100% means that there will be no deposit income from users’ deposits to push relevant users’ withdrawals. At the same time, users’ withdrawals will push up the borrowing interest rate, which will drive the relevant users to repay their borrowings.

Step 4: Adjust the maximum LTV ratio of the asset to 0% 3 weeks after the proposal is passed

As many users still have outstanding borrowings by using that asset as collateral.

Within 3 weeks after the proposal is passed, users will be notified as much as possible to repay their borrowings of other assets and disabled the asset as collateral.

During which time the maximum LTV ratio adjustment will be executed immediately if there are no more users using that asset as collateral for borrowing.

After 3 weeks, the maximum LTV ratio will be adjusted to 0% all at once.

Disclaimer: Liquidation caused by the adjustment of the maximum LTV ratio is a normal market behavior, and the protocol has no obligation to compensate.

Indeed, let’s keep only the most reliable assets. I support this plan.

BSC的fil存款规模排名靠前,存储赛道除了fil也没啥其他更好的币了。建议保留bsc链上该币种。

这些资产其实有不少确实都没啥存在感了,留着反而多一个风险不如下了好。经过这次熊市,才能看出来谁是在裸泳,暴风雨快来的时候,筑城墙,是负责任的做法。期待V2,期待未来的新市场,新玩法 :partying_face: :partying_face:

有道理,可以留个火种?

感谢你的评论,FIL 在 OKC 还有 HECO 上流动性可能有点低了,但在 BSC 上的交易流动性确实还是可以的,如果大家认为 FIL 未来还是有机会的话,那么可以在 BSC 上保留。

支持保留fil,选择最优的链,用户基础还是有的,后期流动性下降,再投票下架。

uni没必要下架!
