Add cbBTC Market to Moonwell on Base

Summary

I propose the addition of a cbBTC (Coinbase wrapped BTC) market to Moonwell’s Base deployment. This proposal aims to initiate the process of listing cbBTC, allowing the Moonwell community and risk managers like Gauntlet to prepare for its imminent launch. By positioning Moonwell as an early adopter of this significant asset, we align ourselves with Base’s vision of becoming a major hub for Bitcoin DeFi and further catalyzing the growth of the world’s largest onchain economy.

Background

  • cbBTC is an upcoming wrapped Bitcoin derivative expected to launch on the Base network very soon.
  • It aims to become the dominant Bitcoin variant on Base, replacing WBTC as the trusted solution for Bitcoin DeFi following the announcement of WBTC custodian BitGo’s new ownership structure.
  • Jesse Pollak, creator of Base, has emphasized his desire to build a massive Bitcoin economy on the network.

Objectives

  1. Initiate the listing process for cbBTC on Moonwell.
  2. Prepare the Moonwell community and risk managers for the asset’s launch.
  3. Ensure Moonwell is among the first onchain finance apps to support cbBTC on Base.

Benefits to the Moonwell Community

  1. Early Adoption Advantage: Position Moonwell as a leader in supporting Coinbase’s onchain initiatives and work to build substantial liquidity for cbBTC early in the asset’s life cycle.
  2. Market Diversification: Expand Moonwell’s offerings, introducing the first Bitcoin-based lending market on Moonwell’s Base deployment.
  3. Increased TVL and Revenue Potential: Leverage the popularity of Bitcoin collateralization, as evidenced by WBTC’s performance on Moonbeam, which is the largest Moonwell market by TVL on the network.
  4. Strategic Alignment: Support Base’s vision of becoming a hub for Bitcoin DeFi and further building out of the onchain economy.

Implementation Roadmap

  1. Community Engagement
  • Gather feedback and refine the proposal based on community input.
  • Update with new information about cbBTC as it becomes available.
  1. Preliminary Approval
  • Conduct a Snapshot signal vote vote to gauge community support.
  1. Risk Assessment
  • Engage Gauntlet to perform risk analysis if Snapshot vote is successful and once cbBTC is deployed onchain.
  • Develop initial risk parameters based on this assessment.
  1. Formal Onchain Proposal
  • Submit a Moonwell Improvement Proposal to activate the cbBTC market.
  • Incorporate Gauntlet’s recommended initial risk parameters.

Token Details

  • Asset Name: cbBTC (Coinbase Bitcoin)
  • Network: Base
  • Purpose: To serve as a liquid, trusted Bitcoin representation on Base, enabling people to utilize their BTC holdings in the onchain economy.

Market Risk Factors

As cbBTC is not yet live onchain, we currently lack specific data for traditional risk metrics. However, as a community we recognize the importance of these factors in assessing the asset’s suitability for listing on the Moonwell Protocol. I commit to providing additional market risk information as soon as it becomes available post-launch.

Key metrics will include:

  • Market Capitalization
  • Total Supply and Circulating Supply
  • CEX/DEX Trading Volume and Liquidity Depth
  • Oracle Information
  • Price Volatility
  • Number of Holders
  • Distribution of Holdings
  • Slippage Analysis on DEXs

Conclusion

While we eagerly await cbBTC’s launch on Base, initiating this proposal now is critical to cementing Moonwell’s position as a leader in the rapidly evolving onchain economy. This proactive approach not only demonstrates our commitment to innovation but also ensures we are fully prepared to integrate cbBTC swiftly and safely once it goes live.

The addition of cbBTC to Moonwell represents more than just another new market—it’s a strategic move that aligns our community with Base and our protocol with the future of Bitcoin DeFi. By being among the first to support cbBTC, we have the opportunity to help shape the landscape of onchain finance and further establish Moonwell as a cornerstone of the Base ecosystem.

Upon passing the snapshot vote and asset going live on-chain, Gauntlet will be happy to provide expedited risk recs for this new market.

I am voting in favor of this proposal once it hits Snapshot. The addition of cbBTC to Moonwell would promote safe capital growth on Moonwell and help align us with Base’s future moving forward. It’ll add a new listing that could increase revenue and TVL.

I will be a yes on this.

Tentative yes. It feels premature to be discussing adding a product that Coinbase has not released any details .

The history with cbETH, the partnership with Coinbase smart wallet; the general success and momentum with Base means it is likely to be a positive outcome, but there is nothing to analyze today.

Supporting Data

Market Specifications

cbBTC is Coinbase’s wrapped version of BTC, given the strong success of cbETH on Base, we believe likely outcomes for cbBTC given the overarching speculation and skepticism regarding WBTC’s custodial process. At this point there aren’t any relevant markers for market data, however, due to the similar nature of cbBTC to WBTC, Gauntlet can recommend risk parameters that mirror WBTC.

Supply and Borrow Caps

Given no liquidity data, Gauntlet recommends supply and borrow caps that are sufficient to initialize the market. Depending on the prevailing liquidity conditions, Gauntlet will use Cap Guardian to adjust caps further. We currently recommend a supply cap of 0.001 cbBTC and borrow cap of 0.0005 cbBTC. These caps would be sufficient to initialize the market, while capping any risk to the protocol.

IR Parameter Specifications

We recommend setting the initial IR curves matching those of WBTC on Optimism. Gauntlet will monitor this asset and adjust IR parameters based on prevailing conditions.
