Contract security measures

SWC-103 (Floating pragma)

Specific compiler pragma 0.8.6 used in Balancer contract to avoid accidental bug inclusion through outdated compiler versions.

SWC-105 (Unprotected Ether Withdrawal)

withdraw is protected by checking that the balance amount doesn't exceed the sender balance in the contract

SWC-135 Code With No Effects

There are a good amount of unit tests that verify correct behaviour of the smart contract code.

Modifiers used only for validation

All modifiers in Balancer contract only validate data with require statements.
