Upbit opened Bifrost’s BFC trading against the South Korean won and USDT on September 10, 2026, expanding the token beyond its existing Bitcoin-denominated market. Trading in the BFC/KRW and BFC/USDT pairs began at 13:45 Korea Standard Time, or 04:45 UTC. Upbit initially restricted purchases for approximately five minutes, blocked sell orders priced more than 10% below the previous BTC-market closing price, and accepted only limit orders during the first two hours. The exchange specified Bifrost Network as the only supported blockchain for BFC deposits and withdrawals, warning that transfers through unsupported networks would not be automatically credited and could require a lengthy recovery process. Bifrost describes BFC as a utility asset for its multichain infrastructure and BiFi decentralized-finance services, including BTCFi, which allows users to mint BtcUSD against Bitcoin collateral. Upbit did not report a delay or verified sustained price reaction after the launch.
