BounceBit has launched V3 of its platform, now branded as "Big Bank," featuring a native integration of a perpetual contract decentralized exchange (DEX) and a new interest-bearing token standard. The upgrade introduces BB tokens, such as BBTC and BBETH, which automatically rebase to increase user balances as earnings accumulate. Users can deposit directly on BTC and ETH chains, with the system minting corresponding BB tokens on the BounceBit chain, streamlining cross-chain transactions. The new perpetual DEX includes a liquidity provider token, BLP, enabling holders to earn fees as counterparties. Platform-generated fees will support the native BB token through a buyback mechanism, enhancing its value proposition.
