Q&A

Answers about safety, controls & treasury operations

What risks should I be aware of?

Byzantine's infrastructure is designed to mitigate market risk, bank counterparty risk, and borrower default risk through over-collateralisation and automated liquidation. The primary remaining risk is technical - related to smart-contract or protocol infrastructure. This is mitigated through multiple audits, continuous monitoring, automated kill-switches, and an optional Aon insurance policy that can compensate for covered technical incidents.

Is my principal protected in all market conditions?

Yes. All credit is over-collateralised and positions are liquidated automatically if collateral value deteriorates. This structure virtually eliminates borrower default risk. Very limited technical risk remains, which can be optionally insured through Aon.

How long do withdrawals take in practice?

Withdrawals have no lockup and typically settle within minutes. During high-activity periods, settlement may take slightly longer as liquidity buffers refill, but the process remains intraday. Treasurers retain continuous access to their funds.

What happens to my funds if Byzantine becomes unavailable?

Client assets sit in segregated product accounts and never touch Byzantine’s balance sheet. Even in an operational disruption, treasury assets remain accessible, supported by continuity procedures.

Can returns ever turn negative?

No. Byzantine does not invest in rate-sensitive instruments. Returns are driven by short-term liquidity demand from institutional borrowers. Credit markets cannot produce a negative return, and even the worst historical monthly performance has remained positive.

How do accounting, reconciliation, and reporting work?

Users receive clear statements, real-time dashboards, and monthly reports for accounting and audit purposes. All transactions are fully traceable, simplifying reconciliation with existing finance systems.
