 You can also take a look at the two contract interfaces that make up the GSN protocol: {IRelayRecipient} and {IRelayHub}, but you won't need to use those directly.

 == Receiving a relayed call
 
 The first step to writing a recipient is to inherit from our GSNRecipient contract. If you're also inheriting from other OpenZeppelin contracts, such as ERC20 or Crowdsale, this will work just fine: adding GSNRecipient to all of your token or crowdsale functions will make them GSN-callable.
