Too Long; Didn't Read

In the case of a metatransaction, the user creates a structure describing a transaction, and then digitally signs it with their private key. It is similar to writing a check for someone. The digitally signed transaction is then sent to a relay node, which submits it to a smart contract. The contract verifies the signature, and if it is valid, executes the transaction. The relay node pays for the execution of the contract.
