# Earning with USDB

This guide covers **USDB Stablecoin Savings**—a two-layer flow for stablecoin holders:

* **Layer 1 — sUSDB (BSR):** stake USDB to receive **sUSDB** and earn via the Base Savings Rate (BSR).
* **Layer 2 — sUSDB Savings Pool:** depoist sUSDB to earn **additional Sui rewards**.
* Total APR = BSR + Sui rewards APR

**Entry point:** go to **Earn → Stablecoin Savings** to start.

***

### Deposit

1. **Choose deposit asset & amount**
   * Select **USDB** to deposit directly, or pick a supported stablecoin.
   * If non-USDB, the app will **swap to USDB** first (Route and **swap rate** shown).
2. **Review the preview(Route)**
   * See swap simulation, **minted sUSDB** (from USDB) and the **Savings APR** you’ll earn after depositing into the Savings Pool.
3. **Confirm(Deposit)**
   * Atomically performs:\
     Swap for **USDB → stake USDB for sUSDB → deposit sUSDB into the sUSDB Savings Pool**.
4. **Track**
   * Your Savings position and **claimable Sui rewards** appear on the page and on the **Dashboard**.

> Notes: **No deposit/withdraw fee. No lockup.**\
> Claims are available from both **Stablecoin Savings** and **Dashboard** when you have a Savings position.
