To streamline protocol-level CDP management, Giga CDP is considered a decentralized portfolio. This portfolio comprises collateral in various tokens and liabilities in various gigaAssets, all across multiple blockchains. Collateral weights are positive, while liability weights are negative.
The protocol operates an internal accounting system built on top of this decentralized portfolio, which serves as the foundation for all liquidity management within the Giga CDP. This accounting system breaks the overall portfolio into segregated virtual markets parametrized by the $C-$D pair ($C - collateral asset, $D - synthetic gigaAsset). In simple words, the system links a specific part of the gigaAsset $D supply to a defined fraction of a particular vault containing the collateral asset $C. The diagram below illustrates the relationship between vaults and virtual markets:
Each virtual market is characterized by its market LTV parameter, defined as the ratio of the total gigaAsset $D issued in this market to the total amount of collateral asset $C virtually allocated to it. Other essential parameters that Giga CDP constantly tracks include average system LTV, total collateral, and total synthetic debt.
A combination of these parameters lay in the foundation of the portfolio management system. Its central feature is ensuring the protocol solvency and targeting a certain level for the overall portfolio LTV.
