On April 8, the decentralized stablecoin USDD announced the official launch of two WBTC Vaults, allowing users to use WBTC as collateral to mint USDD. This adds a premium collateral option to the existing TRX, sTRX, and USDT Vaults of USDD. The introduction of the WBTC Vault further enriches the variety of USDD collateral types, enhances the overall security and robustness of the protocol, and provides users with more stable cross-chain income opportunities.

The USDD team stated, "The launch of WBTC Vaults is an important step for the USDD protocol in diversifying collateral assets, enhancing security, and improving user experience. We will continue to deepen our integration with the Bitcoin ecosystem to provide global users with a safer, more flexible, and more profitable stablecoin solution."

WBTC Vault Launch: Low Barrier to Entry and Dual Income Strategy

It is reported that the two newly launched WBTC Vaults are WBTC-A and WBTC-B. Among them:

WBTC-A has a minimum collateral ratio of 150%, a minimum borrowing amount of $1,000, and a debt ceiling of $10 million;

WBTC-B has a minimum collateral ratio of 130%, a minimum borrowing amount of $2,500, and a debt ceiling of $10 million.

Currently, WBTC Vaults only support the TRON network, and may be expanded to other mainstream public blockchain platforms in the future. TRON network users can connect their wallets on the official website to deposit WBTC directly for USDD. Cross-chain users can operate cross-chain to the TRON network through the official cross-chain bridge or custodial channels, transferring to TRON wallets to mint in the two WBTC Vaults.

Additionally, users can enhance returns through two efficient strategies. The first is leveraging to do a circular long, where users collateralize WBTC to borrow USDD, then exchange WBTC on a DEX for re-collateralization, amplifying BTC exposure without introducing additional funds; the second is cross-platform arbitrage, where users borrow USDD and deposit into high-yield mining pools to earn net interest spread.

USDD Collateral Asset Diversification

Being the largest and most recognized asset for Bitcoin tokenization, WBTC holds over 119,000 BTC, with a market capitalization of $8.5 billion, capturing over 60% market share. The addition of WBTC significantly enhances the diversity and robustness of the USDD collateral pool.

USDD Vaults have long been known for their industry-low stability fees, low participation thresholds, and flexible exit strategies (PSM 1:1 no-loss exchange for USDT). The introduction of the WBTC Vaults further strengthens USDD's diversified collateral strategy, providing users with a richer array of cross-chain wealth management options.

On January 22 of this year, WBTC's custodian BitGO went public on the New York Stock Exchange, meaning it has established a close connection with traditional finance, achieving comprehensive recognition in compliance, transparency, and security. As a custodial asset of BitGo, WBTC possesses dual trust from both crypto finance and traditional finance.

Since the beginning of this year, another U.S. listed company, TRON.INC, has also been continuously increasing its TRX holdings. The addition of WBTC makes the collateral assets in the USDD Vault primarily consist of top ten assets in the crypto market and high-quality assets recognized by traditional financial markets. Through the security and stability of collateral assets, USDD advantages with more transparency and stability, enhancing its position in the stablecoin sector.

Further Strengthening the Security and Robustness of the USDD Protocol

Incorporating WBTC as collateral will further enhance the security and robustness of USDD, marking another milestone for the protocol and comprehensively improving the future development of the USDD ecosystem.

With this layout implemented and expanded, USDD will broaden its collateral assets from a focus on TRON ecosystem assets to global core assets, reducing reliance on a single ecosystem, making the overall collateral more stable amidst market fluctuations, and lowering risk concentration, greatly enhancing system robustness.

Additionally, Bitcoin, as a safe-haven asset, already possesses deeper global liquidity and widespread market consensus. When other types of collateral assets encounter significant volatility and liquidity pressure, the resilience of WBTC will help USDD maintain price anchoring in extreme market conditions, reducing the likelihood of systemic risk caused by black swan events.

The addition of WBTC also means USDD can attract wider market funds, particularly inflows from Bitcoin holders, bringing external high-quality assets into the USDD Vaults, optimizing the results of collateral assets, and thus improving security and stability over the long term.

Since completing a brand upgrade in 2025, USDD has rapidly achieved multi-chain deployment on mainstream public blockchain platforms, making it a decentralized stablecoin product easily accessible to users. After launching diversified and continuous wealth management yield activities in collaboration with mainstream exchanges and DeFi protocols, the USDD ecosystem has rapidly expanded, continually validating and strengthening its positioning strategy as the "income-generating USDT." With its anchoring performance, stable yield strategies, and strong self-generating capability, USDD's market penetration and share continue to rise; as of now, USDD's TVL has reached $2.19 billion, with a circulation exceeding $1.54 billion, ranking 8th in the stablecoin market and becoming one of the most outstanding stablecoin brands since 2025. The launch of the WBTC Vault will continue to propel USDD forward on its path as a leading stablecoin product.
