## Summary

We would like to register sKSM on Kintsugi as a first step towards the Kintsugi DeFi Hub launch.

## Tabling

We request that TC upgrade this proposal directly to a referendum.


Register SKSM as a foreign asset

### Summary

I propose that we increase the KSM collateral ceiling for vaults from 15.000 KSM to 60.000 KSM

### Proposal

Since vaults have already locked up most of the current 15k KSM collateral, we should proceed to increase the ceiling for KSM to 60.000. This will allow vaults to increase their collateral and be able to accept more kBTC to be minted. I believe this is also beneficial to the Kintsugi ecosystem!

### Request for fast track:
Also, I request that the proposal be fast tracked in order to avoid the existing ceiling being reached and limiting vaults from adding more collateral. Ideally the fast track would allow for the ceiling to be raised before end of next week. 

Why do we need to raise the collateral ceilings?
The ceilings limit how much BTC a vault can host/store. We started on purpose with a low overall ceiling when launching Kintsugi to have time to fix any issues that might come up. However, it is not feasible for scaling the system and allowing users to issue kBTC to keep the ceilings so low.

Increase KSM Collateral Ceiling to 60.000 KSM - public proposal #31

This referendum has not been executed due to a misconfiguration in the fast-track. Fast-track delay was set to 7,200 blocks. Since this change was needed ahead of time, a new referendum was brought forward instead.

NOT EXECUTED: Duplicate of referendum 3 to upgrade Kintsugi to release 1.7.3

<h1>TL;DR</h1>
Interlay is becoming a one-stop-shop for all things Bitcoin DeFi, launching a DEX and lending protocol. It is proposed that the DEX and lending protocols first launch on Kintsugi, Feb/March 2023. This proposal outlines the suggested DEX pools and lending markets. Possible DEX incentives, to be covered by the Kintsugi treasury, are also outlined for community review

<h1>Intro</h1>
As a preparation for the launch of Kintsugi's DeFi hub (https://tinyurl.com/InterlayRoadmap), this post aims to kick off a community discussion around the suggested structure of the decentralised exchange (DEX), the lending markets and parameters as well as possible liquidity incentives provided by the network treasury.

**DEX**
Launching with only 6 pools to concentrate liquidity into key assets: kBTC, KSM, USDT, MOVR and liquid staking derivatives (LSDs) is suggested.

**Lending**
Just like the design of the AMM focuses on high quality tokens, this is even more true for the lending markets, which rely on battle tested and liquid assets for the safety of the protocol and its users. Pools containing the aforementioned tokens are supposed to provide sufficient liquidity to ensure liquidations.

**Incentives**
To achieve deep liquidity for those assets, this proposal suggests that the community considers allocating treasury funding towards liquidity programs. To that end, the program would deploy 190,000 KINT over the course of 3 months. There are discussions around applying for a grant from the Kusama treasury to support liquidity bootstrapping, although applications are currently on hold with no clear timeline due to some legal updates to the program.

<h1>Design</h1>

**DEX**
The pools were designed with the following considerations in mind: minimise slippage for the most demanded assets, minimise risks for LPs and maximise trading volume. See https://tinyurl.com/InterlayDEX for a diagram of interconnection and order flows. Pairs with high trading volume will generate higher yield for LPs and contribute to a sustainable relationship between traders and LPs, reducing the requirement for incentives. An overview of the suggested pools, incentives, and target size can be found in the following table.

According to feedback from the community, the KINT/MOVR pool has been exchanged in favor of a KSM/KINT pool.

Pool #5 is a curve stable pool and will be composed of LKSM, wstKSM, vKSM and sKSM. Pool #6, the KSM-LSD/KSM meta-pool, will allow users to swap KSM into any LSD and vice versa.

**Lending**
Of all available tokens in the Kusama ecosystem, the ones below were identified as being secure and liquid enough to serve as collateral. The max loan-to-value (LTV) ratio enforces the maximum borrowable amount against a user's collateral. If the user's LTV rises above the liquidation LTV, the position can be liquidated. To limit potential damage to user and protocol, the following supply caps are suggested.

Please note, that the suggested max LTV for USDT is close to the liquidation LTV. While this can be a risk for the user, it also improves capital efficiency without adding risk for the protocol. Should a lower max LTV be set to protect the user?

LSDs, including LKSM, vKSM, wstKSM, and sKSM have high demand but lack sufficient liquidity and/or a price feed from DIA or other oracle providers, exhibiting oracle manipulation attack vectors. There is ongoing work with DIA to improve sourcing prices for all LSDs. In addition, the liquidity of LSDs is expected to improve through the LSD-stable-swap pool in anticipation of adding these assets as borrowing collaterals soon.

<h1>Annex</h1>
This part is for the more interested reader and elaborates the process and results of the proposal in more detail. 

**DEX**
While swaps from token A into token B can be routed through multiple pools behind the scenes without affecting the UX of a trader, LPs face a more complex decision process. Some of the key factors that influence an LPs decision are:
- Risks associated with the LP position (volatility, protocol risk, centralization risk, etc.)
- Availability of the token (free float market cap, access within the ecosystem, etc.)
- Utilisation of the pool (real yield from trading fees)
- Alternative investments (other pools or staking)

This proposal focuses on assets that are widely available in the Kusama ecosystem and have shown to create sustainable volumes on other DEXs. The main factors for determining the amount of incentives were the target TVL, as well as the volatility of the token pair. While kBTC/KSM, kBTC/USDT, and kBTC/MOVR have similar annualised volatility in the range of 64% to 72%, KINT/MOVR requires a much higher APR to compensate LPs for the 146% volatility (the same holds true for KINT/USDT or KINT/KSM).

For stable pools, the expected volatility is close to zero. In addition, LPs of the LSD stable pool already generate staking rewards which further reduces the necessity for a high pool APR. For the LSD-KSM meta-pool however, LPs have to give up half of the yield generated via LSDs and thus will likely require a higher, competitive APR.

**Incentives**
The treasury has remained largely untouched, with only a few minor payouts for grants and liquidity incentives on other DEXs: more than 2.48 million KINT remain out of the initial 2.5 million. The recent reduction of Vault rewards has allocated an additional ~230,000 KINT to the treasury budget. Allocating 190,000 KINT to ensure a successful launch and liquidity boost for Kintsugi's DEX seems like a useful spending strategy.  In addition to attracting liquidity, these incentives should also serve to encourage higher kBTC bridging volumes.

**Lending - Risk Parameters**
The estimates for the LTV thresholds that were shown above, were estimated using the same methodology as for the vault collateral, with the same scrutiny and considerations in mind: to safeguard the protocol and its users by ensuring full coverage of the underlying loans. The repository used to arrive at those estimates is publicly available for everyone to confirm the presented estimates or suggest changes to the parameters. A more in-depth description of the methodology and process can be found in the repository: https://github.com/interlay/collateralization-analysis

All thresholds, except for USDT, are estimated against USDT as being the debt, since most loans will likely be raised in USDT. USDT thresholds were estimated against BTC as collateral.
For the launch the analysis outputs a close factor of 50% and a liquidation premium of 110%. This means that a liquidator can close up to 50% of a borrower's position and will receive 110% worth of collateral for the liquidated debt. This should ensure that liquidations are profitable even for larger positions while limiting the potential loss for the borrower. tested. To build up a reserve fund to cover bad debt, 20% of the liquidated amount will go to the treasury's ‘bad weather fund’. Note that for severe under-collateralization, the close factor may cause multiple liquidation transactions to be necessary for clearing bad debt.

**Lending - Interest Parameters**
Following from the above, the proposed calibration of the interest rate parameters at launch is as follows:

Based on the analysis of these exact markets on other protocols, the parameters should, on average, maintain a utilisation close to the optimal rate of 90%. Utilisation close to this rate will limit the spread between supply and borrow rates while maintaining sufficient exit liquidity for suppliers. If the utilisation diverges too much from the optimal rate, this usually creates arbitrage opportunities with other lending protocols.
