External Call Security

External call security focuses on the risks associated with a contract interacting with other contracts on the blockchain. Because the state of an external contract can change unexpectedly, these calls are a major source of vulnerabilities like reentrancy.

In derivatives, external calls are used to interact with price oracles or collateral tokens, making them essential but dangerous. Developers must implement strict checks, use try-catch patterns, and limit the gas forwarded to external calls to prevent them from causing failures or draining funds.

Securing these interfaces is a prerequisite for building reliable cross-protocol financial systems.
