The decentralized stablecoin USDD has launched two WBTC Vaults on the TRON network, enabling users to use Wrapped Bitcoin (WBTC) as collateral to mint USDD. This move expands USDD's collateral options, which already include TRX, sTRX, and USDT, enhancing the protocol's asset diversity and stability. The newly introduced WBTC-A and WBTC-B Vaults require minimum collateralization ratios of 150% and 130%, respectively, with borrowing minimums set at $1,000 and $2,500. Users can leverage these vaults through strategies like leveraged long cycling and cross-platform arbitrage to optimize yields. The USDD team emphasized that this development is a significant step in diversifying collateral assets and strengthening USDD's market position as an "interest-bearing version of USDT."
