# BB-Token Standard (V3)

### What they are

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.

Currently there are 6 BB-Tokens corresponding to specific vaults.

> Before V3 there were no user-facing tokens; positions were tracked internally. V3 standardizes positions as transferable tokens.

### Key properties

* 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.

### Lifecycle

1. Subscribe → Mint: deposit into a V3 vault; receive the BB-token.
2. Accrue → Rebase: vault performance credits holders via periodic positive rebases (total supply and per-holder balances rise).
3. Withdraw → Burn: burn BB-tokens; receive proceeds per vault rules (including accrued yield).

### Staking for stBB rewards

You can stake BB-tokens in the [Farm](https://portal.bouncebit.io/farm) module to earn additional stBB rewards.

* Staking does not change redemption rights; you can unstake and withdraw via the vault.
* Rewards accrue and can be manually claimed from the staking contract.

### FAQ

**Are BB-tokens yield-bearing?**&#x20;

Yes, yield is embedded via rebasing (your balance grows).

**Can I trade or use them as collateral?**&#x20;

Transfer is permissionless. BB-Tokens will soon be integrated in the BounceBit Perps platform to be used as collateral.

**Do stBB rewards replace the rebase?**&#x20;

No, rebasing continues; stBB is an additional incentive layer.

**Where do I find the token address?**&#x20;
