Q&A

Answers about safety, controls & treasury operations

What is Byzantine Prime?

Byzantine Prime lets you earn a stable return on your money, and our infrastructure gives you seamless access. Your assets stay in a segregated structure and earn interest from over-collateralised borrowers who pay for short-term liquidity.

How is interest earned?

Interest is earned from borrowers who post more collateral than they borrow. They pay to access short-term liquidity, and that payment is passed on to you as a stable return.

Is the interest rate fixed?

No. The rate varies slightly over time, but it has remained consistently positive because it comes from real demand for short-term liquidity - not from market movements or speculation.

How is my money protected?

Your money is protected because every borrower must deposit extra collateral to access liquidity. This keeps your funds fully covered at all times. The only remaining risk is technical, which can be optionally insured.

How fast can I withdraw my money?

There are no lockups. Most withdrawals arrive within minutes.

Where is my money held?

Your funds stay in your segregated account, separate from company funds or trading activity. You always remain in control of your balance.

What happens if Byzantine becomes unavailable?

Your money stays in protected, segregated accounts and is never mixed with company assets. Even if Byzantine went offline, you would still retain access through the underlying system that holds the funds.
