Add tBTC to Moonwell Core Market on Base

We propose listing tBTC in Moonwell’s Core lending markets to strengthen BTC liquidity and provide a secure, trust-minimized alternative to traditional wrapped assets. This listing aligns with Moonwell’s mission of making onchain finance secure, accessible and user-friendly for everyone

General

Token Asset Name: tBTC

A description of the project and the token

tBTC is a gateway between Bitcoin and Decentralized Finance. tBTC provides Bitcoin holders open access to the thriving DeFi ecosystems available cross-chain. tBTC allows you to unlock your Bitcoin’s value to borrow and lend, mint stablecoins, provide liquidity and much more.

Existing solutions that bridge Bitcoin to Ethereum require users to send their Bitcoin to an intermediary, in exchange for an ERC-20 token that represents the original asset. This centralized model requires you to trust a third party and is susceptible to censorship, threatening the premise of Bitcoin as a sovereign, secure, permissionless digital asset.

Instead of centralized intermediaries, tBTC uses a randomly selected group of beta node operators running tBTC nodes on the Threshold Network to secure deposited Bitcoin through threshold cryptography. That means tBTC requires a threshold majority agreement before beta operators perform any action with your Bitcoin.

• tBTC is live on 9 chains beyond Bitcoin.
• 340 tBTC active on Base.
• Native minting on Ethereum and Arbitrum with Base coming in Q1.
• tBTC is the only fully permissionless BTC bridge.
• MCAP sitting at 430m
• Live on Aave with 115m TVL.
• Newly added as a collateral asset for SolvBTC on Base.

Benefits to the Moonwell Community

• Further decentralization and trust minimization in the Moonwell stack.
• Give users further opportunity to earn with their Bitcoin on Base.
• Collaboration with the Threshold Network DAO, opening up co-marketing opportunities to boost Moonwell’s reach.

List all of the privileged roles in the token contract. This can include whitelisted EOAs, Multi-sigs, or DAOs.*

Multi-sigs:

tBTC contracts are secured by the Threshold Council’s 6-of-9 multisig on Ethereum Mainnet. The tBTC bridge includes a 24-hour timelock for any upgrades which is also under Councils supervision ensuring transparency and review time. The Threshold DAO contracts are governed by the Governor Timelock Contract which prioritize security and decentralized control within the community.

Collateral Contract	Upgradeable	Threshold Council Multisig	Certain aspects of collateral logic may be adjustable, like collateral ratio thresholds.
Proxy Contracts	Upgradeable	Threshold DAO + Council Multisig	If proxies are used, they can be upgraded via DAO decisions or Threshold Council multisig.
Off-chain Relayers	Upgradeable	DAO Governance	Off-chain components can be swapped or reconfigured.
Frontend (App UI)	Upgradeable	Threshold DAO Devs	Frontend apps, like the mint/burn interface, are fully upgradable and not part of on-chain logic.
Parameter Adjustments	Upgradeable	Threshold Council Multisig	LTV Ratios, collateralization changes, and fee adjustments are upgradeable via the DAO or council.
Governance Contracts	Upgradeable	DAO + Council Multisig	Protocol governance contracts (like proposal logic) can be upgraded.

tBTC is a 1:1 wrapped Bitcoin token on Ethereum. The tBTC token is minted only after the Bitcoin is locked, the system relies on a multi-party custody model (MPC), so no single party controls minting or redemption. Anyone can verify reserves in real time on-chain using Bitcoin and Ethereum explorers. Tools like Dune Analytics and Threshold dashboards give visual transparency on collateralization.

Proof of reserves are shown in: https://tbtcscan.com/

In the period between 1st June 2024 to 10/12/2024, tBTC’s price deviation from BTC was:

Average Deviation: 0.26%

Max Deviation: 1.38%
