token and owner Should Be Immutable in VestedAirdrop

0xshaedyw

Summary

The token and owner variables are declared as mutable but are set only during deployment.

Vulnerability Details

  • Mutable token and owner waste gas and allow unintended modifications if not properly restricted.

  • These variables should be immutable to save gas and enforce immutability.

token: public(address) # Should be immutable
owner: public(address) # Should be immutable

Impact

  • Increased gas costs and potential security risks if variables are accidentally modified.

Recommendations

  • Declare token and owner as immutable:

TOKEN: public(immutable(address))
OWNER: public(immutable(address))

  • Initialize them in the constructor:

TOKEN = token
OWNER = msg.sender
