Concerns about WBTC custody at MakerDAO

BitGo's recent announcement about transferring control of the Wrapped Bitcoin (WBTC) product to a joint venture with BiT Global has raised concerns

BitGo recently announced that it will be transferring control of the Wrapped Bitcoin (WBTC) product to a joint venture with BiT Global. This move has raised concerns within the MakerDAO community.

The restructuring is set to be completed in 60 days and will see a collaboration with Justin Sun and the Tron ecosystem. Notably, WBTC custody will be moving to multiple jurisdictions, including Hong Kong and Singapore, in a significant shift from its current custody in the United States.

Justin Sun's involvement in this new control structure has raised particular worries, especially given his past experience with the control of the TrueUSD (TUSD) stablecoin. Since TUSD was transferred to their control, the currency has faced issues with operational transparency and deteriorating processes, including the suspension of real-time proof of reserves and several disruptions in redemption services.

Against this backdrop, BA Labs, a web3 risk analysis team, has warned of the potential risks that MakerDAO could be opening itself up to by continuing to allow WBTC to serve as collateral for the minting of its DAI stablecoin. To mitigate these risks, BA Labs has proposed several actions.

Among their recommendations is a reduction of the debt limits on WBTC core vaults to zero and the disabling of WBTC lending on the SparkLend protocol. These measures are intended to limit MakerDAO’s exposure to any potential issues arising from the change of control of WBTC and ensure the stability of the protocol.

The MakerDAO community is now engaged in a discussion regarding these recommendations, with some members supporting the caution suggested by BA Labs and others viewing the proposed measures as extreme.

Given the importance of WBTC collateral in the decentralized finance (DeFi) ecosystem, any such decision is bound to be taken with great care. Meanwhile, BitGo has sought to allay concerns by assuring that the underlying security of WBTC will not change with the new structure. BitGo CEO Mike Belshe has emphasized that the company will continue to co-sign transactions and that custody will be adequately secured.

However, BA Labs has pointed out that critical information is missing from BitGo's announcement, including the corporate details of BiT Global and the reasoning behind the restructuring. Additionally, Galaxy Digital's recent failed acquisition of BitGo has raised concerns about BitGo's financial stability, heightening worries about the counterparty risk that BitGo could pose to MakerDAO and other protocols relying on WBTC as collateral.

As the MakerDAO community continues to deliberate on the best course of action, the DeFi ecosystem is keeping a close watch on the developments concerning WBTC and its future governance. Whatever decision is made by MakerDAO could have significant implications for the stability of DAI and the role of WBTC within the crypto space at large.
