The interest rate on Boxes isn't set by Bitso. It's set by the market, based on lending demand within the Morpho protocol, so it can go up or down over time. The USDC rate currently varies roughly between 4% and 8% annually. The rate shown in the app is always the current rate, updated in real time.

MORPHO rewards

Besides the yield your USDC earns, Boxes may distribute MORPHO tokens as an additional reward. Claim these tokens directly on your Boxes detail page. They're sent straight to your Bitso account. Like the yield itself, MORPHO rewards are variable and aren't guaranteed.

Tax on your earnings

You're responsible for reporting and paying any tax on your Boxes yield and on any MORPHO rewards you claim. Bitso doesn't provide tax advice. If you have questions about how tax applies to your situation, speak with a qualified professional.
