* Use `delete` on arrays to delete all its elements.
* Use shorter types for struct elements and sort them such that short types are grouped together. This can lower the gas costs as multiple SSTORE operations might be combined into a single (SSTORE costs 5000 or 20000 gas, so this is what you want to optimise). Use the gas price estimator (with optimiser enabled) to check!
* Make your state variables public - the compiler will create [getters](#accessor-functions) for you for free.
* If you end up checking conditions on input or state a lot at the beginning of your functions, try using [modifiers](#function-modifiers)
* Make your state variables public - the compiler will create :ref:`getters <visibility-and-accessors>` for you for free.
* If you end up checking conditions on input or state a lot at the beginning of your functions, try using :ref:`modifiers`.
* If your contract has a function called `send` but you want to use the built-in send-function, use `address(contractVariable).send(amount)`.
* If you want your contracts to receive ether when called via `send`, you have to implement the [fallback function](#fallback-functions).
* If you do **not** want your contracts to receive ether when called via `send`, you can add a throwing fallback function `function() { throw; }`.
* Initialise storage structs with a single assignment: `x = MyStruct({a: 1, b: 2});`
