# How transaction work

## Relayers and Meta Transactions

Sef wallet uses meta transactions which are signed and submitted to the blockchain via a relayer. The relayer pays the gas fee and the wallet refunds the relayer up to the amount signed by the wallet's owner.  This process provides convenience to the user by not requiring a separate account to pay the fee, and yet another account to manage and backup.
