The New wBTC Custody Model and How It Compares with dlcBTC

Key Takeaways

• BitGo recently revised the custody model for wBTC, initially proposing a multi-jurisdictional setup that raised concerns over centralization and regulatory risks. Following community backlash, BitGo introduced a third key holder to improve decentralization, but questions about transparency and regulatory compliance remain.
• The recent changes to wBTC's custody model highlight the ongoing challenges of using wrapped Bitcoin in DeFi. The situation underscores the critical need for secure, transparent, and decentralized custody solutions in the crypto space to maintain trust and stability.
• dlcBTC offers a more secure and transparent alternative to wBTC by focusing on self-custody, on-chain transparency, and minimal regulatory risks. With its decentralized approach, dlcBTC addresses the vulnerabilities of traditional custodial models, providing a safer option for using Bitcoin in DeFi.

Since 2019, BitGo has been the primary custodian and token issuer of Wrapped Bitcoin (wBTC), a token that has played a crucial role in enabling Bitcoin to be utilized in DeFi ecosystems. Recently, BitGo announced changes to its wBTC custody model, sparking concerns among industry players due to the potential risks introduced. 

Although BitGo quickly revised its proposal, the debate over wBTC's centralized custody model continues, raising questions about its security, regulatory compliance, and transparency. This article explores the developments surrounding wBTC's custody model and how it compares with dlcBTC, a more decentralized alternative.

What Exactly Happened? 

wBTC was a groundbreaking innovation that brought Bitcoin liquidity to DeFi, growing into a top-15 token with over $10 billion in TVL. However, its reliance on BitGo as the sole custodian has always been a point of vulnerability. Despite BitGo's strong reputation, concerns over the lack of on-chain transparency and potential regulatory risks persist.

BitGo's recent announcement to transition wBTC's custody to a "multi-jurisdictional and multi-institutional" setup raised alarms in the crypto community. 

The proposal effectively gave BiT Global, an entity associated with the TronDAO ecosystem, control over two of the three keys, raising concerns about centralization, regulatory uncertainty, and trust issues. The proposal led to significant backlash, including MakerDAO halting new borrowing against wBTC and Coinbase announcing a competing product, cbBTC.

In response to the outcry, BitGo revised its proposal on August 14, 2024, as follows:

• 3 jurisdictions: United States, Hong Kong, and Singapore.
• 3 institutions: BitGo Inc., BiT Global, and BitGo Singapore Ltd.
• 2-of-3 cold-storage multi-signature setup: Each institution holds one key.

While this revision addressed the immediate centralization concern, questions about BiT Global's role, regulatory compliance, auditability, and emergency procedures remain.

The Implications of BitGo's Proposal on DeFi 

BitGo's updated proposal has far-reaching implications for the DeFi ecosystem:

1. Decentralization Concerns: The continued reliance on centralized entities for custody in wBTC might prompt the development of more decentralized BTC wrapping solutions.
2. Increased Scrutiny: DeFi projects may demand more rigorous vetting of custody arrangements for all wrapped assets, potentially leading to a diversification of BTC-based collateral options.
3. Trust and Transparency: The situation underscores the importance of transparency and trust in custody models, which can significantly impact the stability and growth of the DeFi ecosystem.
