According to an official announcement, Bitget’s staking and borrowing platform has added stock tokens (rTokens) as collateral assets. The first batch includes 26 popular U.S. stocks and ETF tokens, such as rNVDA, rAAPL, rGOOGL, and rQQQ, covering sectors including technology, semiconductors, and index funds. Users holding these stock tokens can now use them as collateral to borrow mainstream assets like USDT and USDC, unlocking capital liquidity without selling their positions. The web-based feature is already live, while the app version will launch next week. For specific collateral parameters and more details, please refer to Bitget’s official platform. It is noted that rTokens, identified by the format of the letter 'r' plus the stock ticker (e.g., rNVDA for Nvidia), are issued by Reality, Bitget’s licensed Real-World Asset (RWA) protocol. Via a partnership with regulated broker Alpaca, they directly connect to global liquidity pools including the Nasdaq and New York Stock Exchange. Their key features include: 1:1 reserve of underlying assets held by licensed custodians, stock dividends distributed on a 1:1 basis in token form, synchronized mapping of corporate actions (such as stock splits and consolidations), and eligibility as combined margin for unified accounts and U.S. dollar-denominated contracts, enabling users to flexibly manage their funds while holding global stock assets.
