Gas Fee Subsidy
A gas fee subsidy is a mechanism used by decentralized applications or protocols to reduce the barrier to entry for users by covering the cost of transaction fees on the underlying blockchain. In many cases, users interacting with smart contracts must pay gas in the network's native token, which can be expensive and complex for those unfamiliar with blockchain mechanics.
To improve user experience and drive adoption, projects may implement meta-transactions or relayer services that pay these fees on behalf of the user. The protocol then recovers these costs through internal fee structures or by subsidizing them from the project treasury.
This approach makes decentralized finance platforms feel more like traditional web applications, as users can perform actions without holding native gas tokens. However, this introduces a central point of dependency where the entity providing the subsidy must remain operational and funded to keep the service accessible.
