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.
