Definition ∞ Gasless transactions are operations on a blockchain network where the transaction fees, commonly known as “gas,” are not paid by the user initiating the transaction. Instead, a third party, such as a decentralized application (dApp) or a relay service, covers these costs. This mechanism simplifies user experience by abstracting away the complexity of managing native tokens for fee payments. It is often employed to improve the accessibility of blockchain applications.
Context ∞ The discourse around gasless transactions frequently addresses their implementation strategies and their impact on dApp adoption and user retention. Key debates involve the economic models for subsidizing these transactions and the potential for abuse or centralization risks. Future developments are likely to concentrate on optimizing relay networks and exploring alternative fee structures to ensure the sustainability and decentralization of gasless transaction models across various blockchain ecosystems.
