Backpack has introduced its Borrow/Lend feature in Japan, allowing users to earn variable returns by lending assets without selling them. The service also enables borrowing against collateral such as BTC, ETH, SOL, XRP, and USDC. This new feature is integrated into the Backpack Point rewards system. Backpack cautions users about the liquidation risks associated with lending and borrowing, noting that the service does not currently cover spot and futures trading.
