Threshold, a decentralized finance (DeFi) protocol, has put forward a proposal to merge its Bitcoin wrapper token, tBTC, with Wrapped Bitcoin (WBTC) to prevent a potential takeover by Justin Sun. The proposal, introduced on August 29, aims to protect WBTC following concerns over a possible shift in control of the widely used Bitcoin wrapper. These concerns arose from a recent announcement by BitGo, the custodian managing the Bitcoin reserves backing WBTC, regarding a partnership with BiT Global, a Hong Kong-based cryptocurrency exchange. This partnership involves BiT Global taking partial control of the multisignature wallet holding the Bitcoin reserves for WBTC, sparking fears within the community about potential misappropriation of collateral associated with Sun’s projects.
In response to these concerns, Threshold’s proposal suggests replacing WBTC’s current centralized custody and merchant-based minting and burning model with Threshold’s decentralized custody and permissionless mint/redeem mechanism. By doing so, control of WBTC would be transferred to the Threshold decentralized autonomous organization (DAO), which promises a more secure and transparent management model. This move aims to decentralize WBTC and bring a trustless two-way bridgeable version via tBTC, as highlighted by proponents of the proposal. WBTC is the most popular Bitcoin wrapper token, with a market capitalization of approximately $9 billion, and plays a crucial role in allowing BTC to be utilized in DeFi applications on the Ethereum blockchain.
Under the proposed plan, the DAO would gain full control of WBTC’s minting and redeeming processes, with existing merchants losing their privileges. Additionally, Threshold plans to deprecate its tBTC wrapper, offering tBTC holders the option to redeem their tokens 1:1 for WBTC or native BTC. MakerDAO, a prominent DeFi platform, is also evaluating whether to halt the minting of its DAI stablecoin using WBTC as collateral amidst the restructuring plans. Concerns have been raised about Sun’s involvement in the new WBTC management structure, with fears of potential risks to MakerDAO highlighted by BA Labs. Currently, around 10% of DAI’s token supply is backed by WBTC, and MakerDAO’s vaults hold a significant amount of the token.
Furthermore, with $289.3 million worth of WBTC deposited in SparkLend, accounting for 7% of the protocol’s total value locked, the implications of Sun’s involvement are far-reaching. Sun has addressed concerns about his role in WBTC, clarifying on social media that his involvement is strategic and that he does not control the private keys to WBTC reserves. Threshold’s proposal signifies a push towards decentralization in response to potential centralized control risks, aiming to safeguard WBTC and offer a more transparent and secure management model. It remains to be seen how the DeFi community and involved parties will respond to this proposal and its implications for the broader DeFi ecosystem.
