On April 8, the decentralized stablecoin USDD announced the official launch of two WBTC Vaults, allowing users to mint USDD using WBTC as collateral. This adds high-quality collateral options to USDD’s existing TRX, sTRX, and USDT Vaults. The introduction of WBTC Vaults further diversifies USDD’s collateral assets, enhancing the overall security and stability of the protocol, while providing users with more reliable cross-chain yield opportunities.
The USDD team stated, "The launch of WBTC Vaults is a significant step toward diversifying USDD's collateral assets, enhancing security, and improving user experience. We will continue to deepen our integration with the Bitcoin ecosystem to provide global users with safer, more flexible, and higher-yielding stablecoin solutions."
WBTC Vault is live—participate with low entry barriers and earn dual rewards.
It is reported that the two newly launched WBTC Vaults are WBTC-A and WBTC-B. Among them:
The minimum collateralization ratio for WBTC-A is 150%, the minimum loan amount is $1,000, and the debt ceiling is $10 million;
The minimum collateralization ratio for WBTC-B is 130%, the minimum loan amount is $2,500, and the debt ceiling is $10 million.
Currently, WBTC Vaults support only the TRON network, with plans to expand to other major blockchains in the future. TRON network users can connect their wallets via the official website and deposit WBTC directly to receive USDD. Cross-chain users can transfer WBTC to the TRON network using the official cross-chain bridge or custodial services, and once the WBTC is in their TRON wallet, they can mint USDD through either of the two WBTC Vaults.
Additionally, users can increase their earnings through two efficient strategies. First, they can use leveraged long cycling: by pledging WBTC to borrow USDD, then exchanging USDD for WBTC on a DEX to pledge again, they can amplify their BTC exposure without adding additional funds. Second, they can engage in cross-platform arbitrage: by borrowing USDD and depositing it into high-yield mining pools, users can earn the net interest spread.
USDD's collateral assets are more diversified.
As the largest and most market-recognized tokenized Bitcoin asset, WBTC holds over 119,000 BTC with a market capitalization of $8.5 billion, capturing over 60% market share. The integration of WBTC significantly enhances the diversity and stability of the USDD collateral pool.
USDD Vaults have long been known for advantages such as industry-low stability fees, the lowest participation threshold, and a flexible exit mechanism (PSM 1:1 lossless exchange for USDT). The launch of WBTC Vaults further strengthens USDD’s diversified collateral strategy, offering users a broader range of cross-chain investment options.
On January 22 of this year, BitGo, the custodian of WBTC, listed on the New York Stock Exchange, signifying a strong connection with traditional finance and comprehensive recognition of its compliance, transparency, and security. As BitGo’s custodied asset, WBTC now benefits from dual trust derived from both cryptocurrency and traditional finance.
This year, another U.S.-listed company, TRON.INC, has also been continuously increasing its holdings of TRX. The addition of WBTC has made the collateral assets in the USDD Vault primarily composed of assets ranked among the top ten in the crypto market and high-quality assets recognized by traditional financial markets. Through the security and stability of these collateral assets, USDD enhances its position in the stablecoin market with greater transparency and stability.
The security and robustness of the USDD protocol have been further strengthened.
Including WBTC as collateral will further enhance the security and stability of USDD, marking another milestone for the protocol and providing a comprehensive boost to the future development of the USDD ecosystem.
With the implementation and expansion of this strategy, USDD will expand its collateral assets from primarily TRON ecosystem assets to globally core assets, reducing reliance on a single ecosystem. This results in more stable collateral overall during market fluctuations, lowers concentration risk, and significantly enhances system robustness.
Additionally, as a safe-haven asset, Bitcoin has established deeper global liquidity and broad market consensus. When other categories of collateral assets experience significant volatility and liquidity pressure, WBTC’s resilience will help USDD maintain its price peg during extreme market conditions, mitigating the impact of black swan events and significantly reducing the likelihood of systemic risk.
The addition of WBTC also means that USDD can attract a broader range of market capital, particularly from Bitcoin holders, bringing high-quality external assets into USDD Vaults. This optimizes the collateral backing, enhancing long-term security and stability.
Since completing its brand upgrade in 2025, USDD has rapidly achieved multi-chain deployment across major public blockchains, making it a decentralized stablecoin product easily accessible to users. Following collaborative launches of diverse and ongoing yield-generating initiatives with leading exchanges and DeFi protocols, the USDD ecosystem has expanded rapidly, continuously validating and reinforcing its positioning as the “interest-bearing USDT.” Driven by its strong peg stability, consistent yield strategy, and robust self-sustaining capabilities, USDD’s market penetration and share have steadily grown. To date, USDD’s TVL has reached $2.19 billion, with a circulating supply exceeding $1.54 billion, ranking it 8th in the stablecoin market and establishing it as one of the most outstanding stablecoin brands since 2025. The launch of the WBTC Vault will further propel USDD’s advancement toward becoming a leading stablecoin product.
