A Gasless Transaction is a blockchain transaction in which the end user does not directly pay the network’s gas fee, because a relayer, paymaster, or sponsoring contract covers the cost on their behalf, typically in exchange for an off-chain signature authorising the action. It removes the requirement that a wallet hold the native gas token before it can transact, lowering the barrier to onboarding new users. Account abstraction standards such as ERC-4337 provide the infrastructure that makes gasless transactions practical at scale.
