Frequently Asked Questions
Common questions from CTOs and technical leads evaluating our Solana gasless transaction infrastructure.
Our framework uses a sponsor-and-relay model. Your application's backend acts as a sponsor, pre-funding a relayer account. When a user initiates a transaction, our SDK signs it with a session key, and our relayer submits and pays for the Solana network fees. The end-user never needs SOL in their wallet, enabling true frictionless onboarding.
