# Over-collateralized zBTC Over-collateralized zBTC represents an approach to creating a Bitcoin-pegged token on the Zayn Network that is backed by more collateral value than the tokens it represents. This method is intended to provide a buffer against volatility and ensure that holders can redeem their zBTC for actual Bitcoin even under adverse conditions. Research in this area focuses on determining optimal collateralization ratios and types of assets that should be accepted as collateral to maintain liquidity and stability without compromising security. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
