# Single-Asset Pools

> Deposit one asset into a lending pool, receive b-Tokens, and earn yield from borrower interest.

Single-asset pools let you deploy one asset from your Margin Account into an external lending pool and earn yield passively. When you deposit, you receive **b-Tokens** - receipt tokens that track your share and accrue interest automatically.

## Understanding b-Tokens

b-Tokens work similarly to vTokens in the Earn section, but they come from a different external protocol. The key concept is the **b-Rate** - the exchange rate between your b-Token and the underlying asset.

**Example:** If `1 bXLM = 1.33 XLM`, depositing 593.99 XLM gives you 447.65 bXLM. As borrowers pay interest, the b-Rate increases - so when you withdraw, your 447.65 bXLM redeems for more than 593.99 XLM. The difference is your earned yield.

Your b-Token balance stays constant. The b-Rate goes up. That's how yield accrues.

  </Step>

  <Step title="View your position">
    After confirming, go to the **All Transactions** tab. Your position chart shows your supplied value over time. The position table shows your b-Token balance, current value, APY, and b-Rate.
