Add Market WBTC on Mainnet

Add Market WBTC on Mainnet

The Compound Growth Program proposes the addition of a WBTC market on Mainnet. The recent movements in the BTC assets space where more and more yield-bearing BTC assets are coming up, are generating demand for WBTC as a base asset.

Motivation

Recently Symbiotic announced accepting Bticoin on the platform. Symbiotic, like EigenLayer facilitates recursive looping strategies. Also with Babylon, the BTC LSTs have also come into play. With multiple avenues of utilization of WBTC with opportunities to earn yield on the asset, the demand for the asset is also increasing.

To make sure that Compound becomes the first major protocol to capitalize on this opportunity we propose the addition of a WBTC market on Mainnet.

Additionally, BTC LRT and LST began less than a week ago at the time of writing this proposal. The assets are still new and are working on adding liquidity on Dexes and adding oracles.

Market Details

Base Asset: WBTC

Collaterals:

Asset Company Etherscan Link
uniBTC Bedrock Link
FBTC FireBTC (Mantle) Link
swBTC Swell Link
LBTC Lombard Link
pumpBTC pumpBTC Link

It should be noted that some of these assets may be vault tokens. In that case we would urge the community to consider listing these assets when instant redemption becomes available for these assets.

Next Steps

We look forward to getting community feedback on the idea.

Swell supports this proposal and looks forward to integrating swBTC onto Compound!

swBTC is a yield bearing ERC-20 Liquid Restaking Token that offers liquidity for users who want to stake their WBTC in protocols like Symbiotic, EigenLayer, or Karak without locking up their WBTC. swBTC allows holders to earn native yield from restaking platforms while simultaneously leveraging swBTC across the DeFi ecosystem. It can be used as collateral in lending and borrowing protocols, DEXs, options platforms, and more.

swBTC enables users to earn restaking yields on their WBTC. As a productive asset, swBTC provides opportunities for users to take on extra leverage. It is particularly valuable for users that execute yield strategies, making it a high-demand collateral and will drive utilization in Compound.

Withdrawals for swBTC are LIVE - unlike Babylon LSTs (for now).

We at PumpBTC strongly support this proposal and look forward to supporting Compound.

$pumpBTC is a liquid staking token on Babylon, offering a 1:1 peg to BTC with instant liquidity. Our aim is to help BTC holders maximize yields through various restaking protocols such as Babylon and Symbiotic, essentially rebuilding WBTC/FBTC/BTCB with native yield.

We’ve partnered with chains like Babylon, Symbiotic, Fuel, Zircuit, Berachain, and Mantle, as well as AVSs like Marlin, Drosera, and Rollchains. Users who deposit WBTC/BTCB/FBTC into PumpBTC can not only enjoy Babylon’s native yield but also benefit from utilities from the Symbiotic ecosystem. As a yield-bearing asset, $pumpBTC can be integrated into various DeFi primitives, allowing users to enjoy diverse returns.

Furthermore, PumpBTC is pioneering as the first BTC LST protocol to introduce a transparency dashboard. This feature allows anyone to verify the security of their underlying assets in real-time, ensuring that every $pumpBTC issued is fully backed by a sufficient amount of BTC.

Withdrawals for $pumpBTC will be available soon. Meanwhile, users can freely trade on decentralized exchanges like Pancake and Curve. Given the current significant BTC price fluctuations, this ensures timely access to exit liquidity for users.

@sharp we can use the Asset Analysis Dashboard to get some idea of the collateral assets. ( Asset Analysis Dashboard)

What do you think can be the two reference assets to compare the collaterals listed here?

[Gauntlet] - WBTC Comet Recommendations

Gauntlet recommends initializing a WBTC Comet on Mainnet with the below collaterals and risk parameters:

Collateral Supply Cap Collateral Factor Liquidation Factor Liquidation Penalty
uniBTC 9 82% 87% 10%
swBTC 13 88% 91% 6%
LBTC 37 88% 91% 6%

We do not recommend initializing the following assets due to their lack of DEX liquidity:

  • pumpBTC

Comet Parameters

Storefront Price Factor: 70%

Gauntlet recommends keeping the Store Front Price Factor at the same value as the Ethereum v3 WETH Comet.

Target Reserves: 250

After Gauntlet’s forum post analyzing Target Reserves, Gauntlet recommends the following Target Reserves.

Initial Reserves: 2

Analysis

uniBTC Liquidity

Dex Category TVL (mil) Link
uniswap_v3 3.53 Link

Total TVL : 3.53M

swBTC Liquidity

pumpBTC Liquidity

curve 0.01 Link

Total TVL : 0.01M

Given the low liquidity for pumpBTC across the market we don’t recommend listing it currently and will review this collateral again in future.

Supply Cap and Liquidation Penalty

Given the varied nature of growth across the above BTC-pegged assets and the outstanding liquidity available, Gauntlet recommends setting the caps at 20% of the available TVL for assets with withdrawals enabled and 15% of the available for assets with withdrawals disabled in order to both, capture the upside while also mitigating concentration risk. Due to concentrated nature of liquidity, the slippage tolerance would be pretty low for the suggested cap amounts. Given the precedence of WETH comet for correlated assets, we recommend an LP of 6% across assets with withdrawals enabled and 10% across those with withdrawals disabled. We will continue to monitor withdrawal capabilities and the liquidity of BTC-pegged assets, adjusting liquidation penalties as necessary.

Liquidation Factor and Collateral Factor

The nascency of market and exchange rate data exhibits high noise in determining suitable parameters for Liquidation and Collateral Factor. Gauntlet recommends aligning these parameters to the most conservative parameters across LRTs on the WETH Comet. We therefore recommend a CF of 88% and an LF of 91%. For uniBTC, we recommend a CF of 82% and an LF of 87%, should the withdrawals be enabled, Gauntlet would further revise the parameters to better reflect risk profile of the asset.

Yield Risk

Similar to ETH LRTs, BTC LSTs and LRTs have elevated yields due to points program. Staking and AVS maturity at launch will cause yield shocks and consequentially elevate slippage magnitude and liquidity on DEXs. Gauntlet would like flag this potential risk to the community.

Liquidity Risk

Liquidity Restaking Tokens (LRTs) present inherent uncertainties concerning liquidity profiles and associated slashing risks. While LRTs serve to reserve liquidity for instant in-protocol redemptions, withdrawals are constrained by rate limitations imposed by the underlying protocols once the reserve pool is exhausted. This limitation poses a potential challenge to maintaining liquidity availability.

Slashing Risk

Since this Comet involves different staking products, there is risk from a double slashing event to both assets.

Points program

Given the prevalence of incentives, we encourage the community to confirm the distribution of points to Compound users. This would enable to attract more TVL and offer competitive rates, enhancing user engagement and protocol growth.

Choice of Oracles

The above recommendations are made keeping Exchange Rate Oracles in mind. We would like to confirm the use of these oracles and get more clarity on the calculation mechanism of the getRate() functions.

IR Curve parameters

Gauntlet is aligning the interest rate (IR) parameters for the WBTC Comet with those of the WETH Comets. The supply APY at the kink is set to double the rate typically seen in other lending markets, while the borrow APY is set at 2.19%. Given the novelty of this market, we’ve chosen an 85% kink to ensure a smoother rate gradient, promoting market balance and potentially attracting borrowers seeking higher APYs. This strategic adjustment should support market stability and adapt to the anticipated demand dynamics.

Parameter Recommended Value
Annual Supply Interest Rate Base 0
Annual Supply Interest Rate Slope Low 0.012
Supply Kink 0.85
Annual Supply Interest Rate Slope High 1
Annual Borrow Interest Rate Base 0.01
Annual Borrow Interest Rate Slope Low 0.014
Borrow Kink 0.85
Annual Borrow Interest Rate Slope High 1.15

Considering the market equilibrium assumption of reaching 85% utilization, the following chart forecasts annualized reserves corresponding to various borrowing amounts. At $300k borrowed, the Comet would generate annual reserves of $3500. We believe these values will tend to grow more as result of increasing liquidity followed by increasing supply caps.

Comp Rewards

Due to the novelty and the current Borrowing capacity of this comet, we recommend setting COMP rewards low. Gauntlet will continue to monitor the incentives and calibrate them depending on market conditions.

COMP Type COMP
Supply Rewards 1
Borrow Rewards 0

I (random comp holder and user) support adding wBTC. Despite the negative hype around it currently it’s been fairly stable/reliable for long enough that it can be reasonably trusted.
