Collateral Fragmentation
Collateral fragmentation occurs when an investor's capital is locked into isolated silos across different decentralized protocols, preventing the efficient use of that capital as margin. Each protocol requires its own collateral to secure positions, meaning a trader must deposit assets in multiple places rather than using a single, unified pool.
This reduces capital efficiency because the trader cannot easily move assets from a low-risk position to cover a high-risk position on another platform. It also complicates risk management, as the trader must monitor several different health factors and liquidation prices simultaneously.
In periods of market stress, this fragmentation makes it difficult to quickly inject liquidity to save a position, leading to avoidable liquidations. It is a common challenge in the fragmented landscape of DeFi where interoperability between protocols is often limited.
Solving this requires the use of cross-chain or cross-protocol margin accounts.
