USDD Officially Launches WBTC Vault to Diversify Collateral Assets and Enhance Security and Stability

On April 8, the decentralized stablecoin USDD officially launched two WBTC Vaults, enabling users to mint USDD using WBTC as collateral. This marks a new high-quality collateral option added to USDD’s existing TRX, sTRX, and USDT Vaults. The introduction of WBTC Vaults further diversifies USDD’s collateral portfolio, enhances the protocol’s overall security and robustness, and provides users with more reliable cross-chain yield opportunities.

The USDD team stated: “The launch of WBTC Vaults represents a significant step forward for the USDD protocol in diversifying collateral assets, strengthening security, and improving user experience. We will continue deepening integration with the Bitcoin ecosystem to deliver safer, more flexible, and higher-yielding stablecoin solutions to global users.”

WBTC Vault Launch: Low-Entry Participation and Dual-Yield Strategies

The two newly launched WBTC Vaults are named WBTC-A and WBTC-B. Their parameters are as follows:

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

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

Currently, WBTC Vaults are only supported on the TRON network, with potential future expansion to other major public blockchains. Users on the TRON network can connect their wallets via the official website and directly deposit WBTC to mint USDD. Cross-chain users may utilize the official cross-chain bridge or custodial channels to transfer WBTC onto the TRON network; once the WBTC arrives in their TRON wallet, they can mint USDD in either WBTC Vault.

In addition, users can adopt two efficient strategies to boost yields. First is leveraged long recycling: users deposit WBTC to borrow USDD, then swap USDD for WBTC on a DEX and re-deposit the newly acquired WBTC—effectively amplifying BTC exposure without adding additional capital. Second is cross-platform arbitrage: users borrow USDD and deposit it into high-yield liquidity pools to capture net yield spreads.

Greater Collateral Diversity for USDD

As the largest and most widely recognized tokenized Bitcoin asset, WBTC holds over 119,000 BTC in custody, with a market cap of $8.5 billion and over 60% market share. Its integration significantly enhances the diversity and resilience of USDD’s collateral pool.

USDD Vaults have long been distinguished by industry-low stability fees, minimal participation thresholds, and flexible exit mechanisms—including the Peg Stability Module (PSM), which enables lossless 1:1 swaps with USDT. The launch of WBTC Vaults further strengthens USDD’s multi-asset collateral strategy and expands users’ cross-chain wealth management options.

On January 22, BitGo—the custodian of WBTC—listed on the New York Stock Exchange (NYSE), signifying its deep integration with traditional finance and broad recognition in compliance, transparency, and security. As a BitGo-custodied asset, WBTC benefits from dual trust anchored in both crypto and traditional financial systems.

This year, TRON.INC—a publicly traded U.S. company—has also been steadily accumulating TRX. With WBTC’s inclusion, the collateral assets in USDD Vaults now consist primarily of top-10 crypto-market assets and high-quality assets recognized by traditional financial markets. By transmitting the safety and stability of these underlying assets, USDD reinforces its position in the stablecoin space through greater transparency and reliability.

Enhanced Security and Robustness of the USDD Protocol

Incorporating WBTC as collateral further bolsters USDD’s security and robustness—marking another milestone for the protocol and delivering comprehensive improvements to the USDD ecosystem’s future development.

With this strategic expansion, USDD broadens its collateral base beyond TRON-native assets to include globally recognized core assets, reducing overreliance on any single ecosystem. This makes the overall collateral portfolio more resilient amid market volatility and lowers concentration risk—significantly enhancing system robustness.

As a proven safe-haven asset, Bitcoin enjoys deeper global liquidity and broader market consensus. When other collateral types face sharp price swings or liquidity stress, WBTC’s inherent resilience helps USDD maintain its peg during extreme market conditions, mitigating black-swan impacts and substantially lowering systemic risk.

WBTC’s inclusion also positions USDD to attract broader market capital—particularly funds held by Bitcoin holders—bringing high-quality external assets into USDD Vaults. This optimization of collateral composition improves 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 an easily accessible decentralized stablecoin. Following collaborative yield-generating initiatives with leading exchanges and DeFi protocols, the USDD ecosystem has expanded rapidly—continuously validating and reinforcing its positioning as the “yield-bearing version of USDT.” Driven by strong peg performance, reliable yield strategies, and robust self-sustaining capabilities, USDD’s market penetration and market share continue to grow. To date, USDD’s Total Value Locked (TVL) stands at $2.19 billion, with a circulating supply exceeding $1.54 billion—ranking eighth among stablecoins and standing out as one of the most impressive stablecoin brands since the start of 2025. The launch of WBTC Vaults will further propel USDD’s ascent among top-tier stablecoin products.
