### What changed in V3?

* The old “Manual / Auto / Fixed” products are gone. You now interact with **one vault per currency**: USDT, BTC, ETH, BNB, SOL.
* Your vault position appears as a **BB-token** on **BB Chain**:
  * Deposit USDT → receive **BBUSD**
  * Deposit BTC → receive **BBTC**
  * (and so on for ETH/BNB/SOL)
* BB-tokens **rebase weekly** so balances automatically reflect accruals.

> **USDC note:** New USDC deposits aren’t accepted in V3. Legacy USDC positions were consolidated into USDT management.

***

### Depositing (Subscribe)

**Goal:** Get a BB-token that represents your vault position.

1. **Choose currency** (USDT, BTC, ETH, BNB, SOL) on a supported origin chain.
2. **Deposit** in the app. A matching **BB-token is minted** to your **BB Chain** address.
3. Optional: **Stake** during subscribe to start earning **stBB** immediately (see lock below).

**Lock window:** If you stake during subscribe—or stake later—the staked portion is **locked for 28 days**. (Unstaked balances are transferable and redeemable after their own initial lock ends.)

***

### BB-tokens at a glance

* **What they are:** Receipt tokens on BB Chain (BBUSD, BBTC, BBETH, BBNB, BBSOL) that represent your vault position.
* **Why they change:** They **rebase weekly**, adjusting your balance to reflect accruals. You don’t need to take action.
* **Transfers:** You can **transfer** BB-tokens on BB Chain; the **underlying position moves with the token** to the new holder.

***

### Staking & stBB rewards

To **continue earning stBB rewards**, **stake your BB-tokens** on BB Chain.

* We **airdropped 0.1 BB** to **eligible addresses** to help cover gas for staking.
* **Rewards:** stBB rewards are **issued daily** on BB Chain. You **claim** them in the app.
* **Lock:** Staked amounts are **locked for 28 days** from each stake action. You can stake later if you didn’t stake at subscribe (that new stake has its own 28-day lock).
* **APR:** May vary by currency and market conditions.

**How to stake**

1. Open **Portfolio** → choose your **BB-token** (e.g., BBUSD).
2. Click **Stake** → confirm.
3. Track **stBB** accruals and **claim** when you like.

***

### Weekly rebase (automatic)

* Happens **once per week** to align BB-token balances with accruals.
* No action required; you’ll see your BB-token amounts **adjust automatically**.

***

### Redeeming (Withdraw)

**Goal:** Burn your BB-token and receive funds on your target chain.

1. In the app, click **Redeem**, choose **amount** and **target chain**.
2. Your BB-tokens are **burned**; the request enters the **weekly processing** queue.
3. After processing, you **claim funds** on the target chain when the **withdrawal time** is reached.

**Notes**

* If part of your position is staked, the app will **close staking** for that portion as part of the redeem flow.
* Any **stBB** you’ve earned remains **claimable**.

***

### Solana users

* You’ll need an **associated EVM address** for some actions and for redemptions back to EVM chains.
* If you transfer your BB-token on BB Chain, the **position and its accruals move with it**.

***

### Migration from V2

* Your V2 positions and unclaimed rewards were **migrated 1:1** into V3 **BB-tokens**.
* Some legacy features (wrap/unwrap, certain bridges, old LP pools) were **retired** as part of the cleanup.
* **Ethena-related** legacy positions were converted to **USDT V3** positioning; any earned third-party rewards were delivered to users as applicable.
