ما هو BOUNCEBIT USD(BBUSD)؟

BB-tokens are rebasing, yield-embedded voucher tokens on BounceBit Chain. They are minted when you subscribe to a V3 vault and burned when you withdraw. Each BB-token corresponds 1:1 (intent) to an active position in a specific vault/strategy. Rebasing yield: yield is paid by increasing balances pro-rata, not by changing price per token. Voucher semantics: each BB-token represents a live position in a specific V3 vault/strategy. Restricted mint/burn: only the vault/strategy can mint or burn; transfers are permissionless. Composability: usable in DEXs, money markets, perps, and staking.
