# V3 FAQ *** > **TL;DR** > > * V3 consolidates everything into **five currency vaults**: USDT, BTC, ETH, BNB, SOL. > * Depositing mints a **rebasing BB-token** on BB Chain (BBUSD, BBTC, BBETH, BBNB, BBSOL). > * **To keep earning stBB rewards, you must stake your BB-tokens.** > * We **airdropped 0.1 BB** to eligible addresses to help cover gas for staking. > * **Rebase is weekly**; **redemptions process weekly**; **stBB rewards issue daily** (you claim). > * V2 positions and unclaimed rewards were **migrated 1:1** into V3. *** ### 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. *** ### What happened to Perps/Trade • Perps and Trade are paused until BLP launches (later this year) • You can withdraw your balance anytime via your profile page. ### How to add more tokens into the swap? You can simply add using the following smart contract:\ symbol: 'AUCTION',\ '0xA9B1Eb5908CfC3cdf91F9B8B3a74108598009096', symbol: 'BSSB',\ '0xda31D0d1Bc934fC34F7189E38A413ca0A5e8b44F', symbol: 'MUBI',\ '0x38e382F74dfb84608F3C1F10187f6bEf5951DE93', symbol: 'AMMX',\ '0xC881255e4D639B42E326158c7b8ccb7F33459261', symbol: 'MBA',\ '0x8492ec2845ae5961394f478F58382C8FDdA6739b', ### Key cycles (for planning) * **stBB rewards:** **Daily** issuance (you claim anytime). * **Rebase:** **Weekly** (balances auto-adjust). * **Redemptions:** **Processed weekly**; you’ll **claim** when the withdrawal window opens. *** ### Quick troubleshooting * **I don’t see my BB-token:** Check you’re viewing your **BB Chain** address. * **My redeem isn’t available yet:** Wait until the shown **withdrawal time**, then claim on the target chain. * **A step failed in subscribe/redeem:** Re-submit in the app; ensure you have **sufficient gas**. Most issues resolve with a retry. *** ### Glossary * **BB-token:** Your position on BB Chain (BBUSD, BBTC, BBETH, BBNB, BBSOL). * **stBB:** Reward token earned by **staking** a BB-token; **claimed** by you. * **Rebase:** Weekly auto-adjustment of BB-token balances to reflect accruals. * **iBBTC:** Institutional receipt for BTC positions; **staking-only**, no rebase. *** ### Need help?
