## Collateral Callability

Collateral callability refers to the specific capability of a protocol to demand additional assets or redeem existing collateral based on predefined smart contract rules. In derivative trading, this ensures that the protocol remains solvent by maintaining the necessary backing for outstanding positions.

If the value of the collateral falls below a certain threshold, the call provision triggers a margin call, requiring the borrower to deposit more assets or face liquidation. This mechanism is the cornerstone of decentralized lending, ensuring that risk is managed autonomously without the need for traditional intermediaries.

It relies on accurate price feeds from oracles to trigger the provision in real-time, making it highly sensitive to network latency and data integrity. Effective collateral callability designs prevent bad debt from accumulating within the system and ensure the stability of the protocol's underlying tokenomics.
