Proposal
Ensure the continued stability of WBTC, the sanctity of its collateral, and the safety of the users and protocols that rely on it by hot swapping the centralized custody and merchant-based mint and burn model with Threshold’s decentralized custody and permissionless mint/redeem mechanism. Make BitGo the largest holder of T via a grant by minting an additional 15% of the current fully diluted supply ($36,415,500 at today’s price).
Background
WBTC is one of the most liquid and widely adopted assets in crypto with a TVL of ~$9B and widespread integrations across DeFi and CEXes. BitGo is the trusted custody provider behind WBTC. Threshold Network’s tBTC is a permissionless and decentralized Bitcoin bridge with a TVL of ~$200M and bridge volume of >$1B since inception.
Recently, BitGo announced their plan to transfer control of the WBTC product to a joint venture with BiT Global to expand the jurisdictional and institutional custody of the underlying BTC. This announcement has proven controversial due to the involvement of Justin Sun, with many in the ecosystem, expressing concern over his “affiliated projects show worrying signs of possible misappropriation” of collateral. The most recent example being the removal of 12,000 BTC from the USDD stablecoin, as reported by Protos.
In response, major DeFi protocols have taken steps to limit or reduce their exposure to WBTC. The day after BitGo’s announcement, MakerDAO proposed to disable further WBTC borrowing (which has since been ratified) and potentially fully offboard the asset in the future. Similarly, Aave is closely monitoring the situation and is prepared to take steps “necessary to ensure the market’s safety and stability.”
There is a better way
Combining WBTC’s user base, integrations, liquidity, and brand recognition with tBTC’s decentralized custody and permissionless bridging mechanism can better achieve BitGo’s stated objective of multi-jurisdictional and multi-institutional custody.
Benefit to ecosystem
This alternative approach would ensure the safety and stability of the underlying collateral, reassure market participants and users of WBTC, and protect the many DeFi protocols that have significant exposure to the asset as collateral.
Benefit to BitGo
Threshold DAO will mint an additional 15% (1,655,250,000 tokens) of the fully diluted supply (currently 11,035,000,000 tokens) with an agreed vesting schedule as a grant for BitGo via a one-off token mint. This grant is worth $36,415,500 at today’s price of $0.022/T and would make BitGo the largest stakeholder in Threshold Network while preserving the decentralized nature of the bridge.
Logistics
The token mint can be executed via an on-chain Governor Bravo proposal.
The merge can be implemented across several stages to ensure a secure and seamless transition for users, partner protocols, BitGo, and Threshold.
-
Stage 1: Threshold is given merchant (mint/redeem) privileges for WBTC and other merchants are removed. The WBTC DAO privileges (e.g. freeze function, etc.) are transferred to Threshold DAO. tBTC minting is disabled and the existing tBTC supply made redeemable 1:1 for WBTC (and remains redeemable for native BTC).
-
Stage 2: Current WBTC TVL migrates to Threshold’s decentralized custody in chunks, with deposits spread across multiple wallets to ensure forward security.
Fallback (if the offer is declined): Facilitating a safe and orderly exit from WBTC
If BitGo declines the offer and proceeds with the new custody arrangement, the DeFi ecosystem will require a safe and orderly offboarding of WBTC. In this case, the token mint can be repurposed to subsidize the costs of offboarding WBTC from the ecosystem and migration to alternatives like tBTC and cbBTC. The exact details can be deferred to Threshold’s Treasury Guild but obvious examples could include covering users’ WBTC redemption fees, subsidizing other protocols’ migration/development work, etc.
