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 is a new high-quality collateral option added to the existing TRX, sTRX, and USDT Vaults. The launch of the WBTC Vault further enriches the types of collateral for USDD, enhancing the overall security and robustness of the protocol, and providing users with more and stable cross-chain income opportunities.

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

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

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

The minimum collateral rate for WBTC-A is 150%, the minimum loan amount is $1,000, and the debt ceiling is $10 million;

The minimum collateral rate for WBTC-B is 130%, the minimum loan amount is $2,500, and the debt ceiling is $10 million.

Currently, the WBTC Vaults only support the TRON network, and may later expand to other mainstream public chain platforms. Users of the TRON network can connect their wallets on the official website to directly deposit WBTC to obtain USDD. Cross-chain users can transfer WBTC to the TRON network through the official cross-chain bridge or custodial channels, and after transferring to the TRON wallet, they can mint in the two WBTC Vaults.

Additionally, users can utilize two efficient strategies to increase returns. First is leveraging to cycle long, where users can deposit WBTC as collateral to borrow USDD and then exchange WBTC on DEX for further collateralization, enlarging their BTC position exposure without additional funds; second is cross-platform interest arbitrage, where users can lend USDD and deposit it into high-yield mining pools to earn the net interest spread.

Diversification of USDD Collateral Assets

WBTC, as the largest and most market-recognized Bitcoin tokenized asset, holds over 119,000 BTC, with a market cap of $8.5 billion and a market share exceeding 60%. The inclusion of WBTC significantly enhances the diversity and robustness of the USDD collateral pool.

USDD Vaults have always been known for their low stable fees, minimum entry barriers, and flexible exit mechanisms (PSM 1:1 lossless exchange for USDT). The launch of the WBTC Vaults further strengthens USDD's diversified collateral strategy, providing users with richer cross-chain financial options.

On January 22 of this year, BitGO, the custodian of WBTC, was listed on the New York Stock Exchange, indicating that it has established a close connection with traditional finance, gaining comprehensive recognition in compliance, transparency, and security. As a custodied 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 holdings of TRX. The inclusion of WBTC makes the collateral assets in the USDD Vault mainly consist of assets in the top ten of the crypto market and high-quality assets recognized by traditional financial markets. By transmitting the security and stability of collateral assets, USDD benefits from enhanced transparency and stability, which will significantly elevate its position in the stablecoin sector.

The Security and Robustness of the USDD Protocol Are Further Strengthened

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

With the implementation and expansion of this layout, USDD will extend its collateral assets from those inclined towards the TRON ecosystem to global core assets, reducing dependence on a single ecosystem. This makes the overall collateral assets more stable in market fluctuations, lowers the concentration of risks, and significantly improves the system's robustness.

Moreover, Bitcoin, as a safe-haven asset, already has deeper global liquidity and wide market consensus. When other categories of collateral assets experience significant volatility and liquidity pressure, the resilience of WBTC will help USDD maintain price anchoring during extreme market conditions, preventing impacts caused by black swan events and greatly reducing the likelihood of systemic risks.

The addition of WBTC also means that USDD can attract broader market funds, especially inflows from Bitcoin holders, bringing external quality assets into USDD Vaults and optimizing the results of collateral assets, thereby enhancing safety and stability in the long run.

Since completing its brand upgrade in 2025, USDD has rapidly achieved multi-chain deployment on mainstream public chain platforms, making it a decentralized stablecoin product accessible to users. After launching diversified and sustainable financial yield activities in conjunction with mainstream exchanges and DeFi protocols, the USDD ecosystem has rapidly expanded, continuously validating and reinforcing its positioning strategy as the "interest-bearing version of USDT." Driven by its anchoring performance, stable income strategies, and strong self-sustaining capabilities, USDD's market penetration and share continue to rise, with a current TVL of $2.19 billion and a circulation exceeding $1.54 billion, ranking 8th in the stablecoin market and becoming one of the best-performing stablecoin brands since 2025. The launch of the WBTC Vault will continue to propel USDD forward on the path of leading stablecoin products.
