Borrower counterparty risk
Borrower counterparty risk
Definition
Borrower fails to repay loan.Mitigation strategy
All loans are over-collateralised with minimum collateral ratios of 120-150%. If that ratio is breached, collateral is automatically liquidated to make lenders whole.To ensure the functioning of this liquidation mechanism, only battle-tested, heavily audited credit marketplaces with an excellent operating history are used - in this case Morpho, Aave, and Maker/Sky.On Friday, Oct 10 2025, Morpho, Aave, and Maker saw liquidations of over $400m in a few hours - with no bad debt and no outages.Details on the liquidation mechanism are found in the upcoming sections.Byzantine counterparty risk
Byzantine counterparty risk
Definition
An insider at Byzantine corrupts the smart contract.Mitigation strategy
Byzantine has no ability to upgrade the smart contract that administers user funds. Additionally, Byzantine never touches or routes user funds. In other words, there is no Byzantine insider risk.Byzantine has the ability to change the asset manager (Keyrock), but this is subject to a lengthy timelock - a period during which Byzantine and third-party monitors can veto this change, or, in the worst case, during which clients have ample time to withdraw their assets.Marketplace counterparty risk (bankruptcy)
Marketplace counterparty risk (bankruptcy)
Definition
Credit marketplace goes bankrupt.Mitigation strategy
This risk is not relevant for the operation of the product. Smart contracts by design fulfil their intended function indefinitely. If the organisation around any of these credit marketplaces goes bankrupt, the smart contracts will continue to operate.Once deployed, even these organisations themselves have no control over their smart contracts. This ensures bankruptcy-remoteness - not just financially, but also operationally.Marketplace counterparty risk (criminal)
Marketplace counterparty risk (criminal)
Definition
Insider at credit marketplace corrupts smart contracts to steal funds.Mitigation strategy
None of the credit marketplaces that Byzantine uses have the unilateral right to alter any of the code in their deployed smart contracts.They physically cannot edit deployed smart contracts even if they wanted to.Liquidity risk
Liquidity risk
Definition
Sudden mass withdrawals or stress event delays redemptions.Mitigation strategy
The credit marketplaces Byzantine works with are extensively battle-tested and have an excellent operating history. Loans are short-term and callable. Even in the rare case that an underlying market runs into liquidity constraints, the market’s automatic withdrawal queue executes withdrawals the second that liquidity is available again.Additionally, Keyrock has the duty to monitor the portfolio for full liquidity, entering and exiting markets based on their ability to allow clients to redeem in full at any time.Custody risk
Custody risk
