FAQ
Frequently asked questions
Everything you need to know about Castar
No. Castar is a financial technology platform, not a bank. It lets you verify ownership of tokenized real-world assets you already hold and put them to work — hold, borrow against, earn on and spend them.
Your assets stay yours. Castar verifies on-chain ownership of the tokenized assets in your own wallet — you remain in control of what you hold rather than handing custody to us.
Borrowing against your assets is not the same as selling them, so it generally isn’t a disposal. This is general information, not tax advice — check your own situation with a qualified adviser.
You get early warnings well before any risk of liquidation, with time to top up collateral or repay part of what you’ve borrowed. Managing your buffer keeps your positions safe.
Top U.S. equities, tokenized end-to-end, plus major tokens across the leading chains. The supported list keeps growing as we add coverage.

Idle balances can earn from selected tokenized asset classes — illustratively up to ~32% a year. That figure is illustrative, not guaranteed, and past performance is no promise of future returns.
