Alchemix Transmuter

Description

The StrategyOp contract interacts with external contracts like ITransmuter and IVeloRouter based on assumed interfaces. If these external contracts change their interfaces or implementations, it could lead to unexpected behaviors or failures.

Impact

• Compatibility Issues: Changes in external contracts' interfaces may cause the strategy contract to malfunction.

• Security Risks: If external contracts are upgraded to malicious versions, it could pose security threats.

Recommendation

• Implement Interface Checks: Use mechanisms to ensure that the external contracts conform to the expected interfaces.
