Zero-Fee Transactions

Definition

Zero-fee transactions are operations on a blockchain or digital asset network that incur no cost to the sender for their processing. While uncommon in many major proof-of-work blockchains, some protocols or layer-2 solutions are designed to offer transactions without direct user-paid fees. This can be achieved through various mechanisms, such as subsidized fees, different consensus models, or off-chain processing. The aim is to improve user experience and encourage microtransactions.
