* Make your state variables public - the compiler will create :ref:`getters <visibility-and-getters>` for you automatically.
* 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)``.
* Initialise storage structs with a single assignment: ``x = MyStruct({a: 1, b: 2});``
* Initialize storage structs with a single assignment: ``x = MyStruct({a: 1, b: 2});``

.. note::
If the storage struct has tightly packed properties, initialize it with separate assignments: ``x.a = 1; x.b = 2;``. In this way it will be easier for the optimizer to update storage in one go, thus making assignment cheaper.
