In the Ask! framework documentation here it says Ask! doesn't provide any "overflow protection", whereas ink! does, but it doesn't explain why. Why doesn't Ask! framework provide any "overflow protection"?

    ink! is written in rust and rust provides overflow/underflow protection, that's why by default ink! support overflow protection. May be AssemblyScript which is used by Ask! doesn't support overflow protection.

Built-in overflow protection doesn't exist in AssemblyScript as of now: https://github.com/AssemblyScript/assemblyscript/issues/447.

You should be able to use a safe arithmetic library though.
