### Exchange Rate

The svBTC:cbBTC exchange rate appreciates as yield accrues:

| ------------ | ---------------------- | --------------------------------------- |
| Deposit Day  | 1 svBTC = 1.0000 cbBTC | 1.0000 svBTC                            |
| After 1 Year | 1 svBTC = 1.0850 cbBTC | 1.0000 svBTC (redeems for 1.0850 cbBTC) |

Your svBTC balance remains constant. Its redemption value increases.
