Sky, the platform formerly known as MakerDAO, is making waves with its latest proposal to offboard Wrapped Bitcoin (WBTC) as collateral. This move has sparked a heated discussion in the DeFi community, especially considering the involvement of Justin Sun and some allegations surrounding him. At the heart of this proposal are concerns over transparency and security in custodial setups. As Sky gears up for a crucial governance vote on September 26, 2024, we might be witnessing a pivotal moment that could reshape the DeFi landscape.
The proposal to remove WBTC from Sky comes from BA Labs, a risk management firm that has raised red flags about BitGlobal, WBTC’s custodian. According to their report, there are serious transparency issues regarding who controls it. They allege that Justin Sun may have control over it through some obscure ownership structures involving shell companies and nominee directors.
BitGo's CEO had previously dismissed such claims but with new information surfacing, it seems like Sky's governance is taking no chances. The proposal also suggests that if Justin Sun can control BitGlobal today, he could control something else tomorrow.
The implications of this proposal are huge. With around $200 million in loans backed by WBTC currently on Sky, removing it as collateral could lead to significant market disruptions. Users are being urged to close their positions or risk liquidation as the platform prepares for an orderly exit.
This isn't just a problem for Sky; other platforms like Aave are also considering similar moves. If everyone rushes to close their positions at once, we might see some serious liquidity issues across DeFi.
Coinbase’s cbBTC seems to be stepping into the spotlight as an alternative. However, it's important to note that while cbBTC offers some advantages—like being backed by one of the most reputable exchanges—it also has its own set of concerns.
For one, its custody model lacks transparency compared to WBTC; we don’t even know which addresses hold the Bitcoin backing it! And while having Coinbase as a custodian might seem safe now, what happens if regulatory conditions change?
Sky’s proposal raises important questions about collateral integrity and custodial risks in DeFi. While moving away from WBTC may address some immediate concerns—especially those revolving around Justin Sun—it feels like we could be trading one set of risks for another with cbBTC.
