Alchemix Transmuter

Description: The interfaces lack comprehensive input validation for critical functions.

In ITransmuter:

• No checks for zero addresses

• No minimum/maximum amount restrictions

• Potential for manipulation in deposit(), claim(), withdraw()

In IVeloRouter:

• No validation for route array length

• No checks for valid token addresses in routes

Impact:

• Potential for DoS attacks

• Risk of economic manipulation

• Unexpected contract behavior

Proof of Concept:

Recommended Mitigation:

• Add input validation checks

• Implement minimum/maximum amount constraints

• Use require() statements for address and amount validation
