Core Capabilities of Our Fee Abstraction Protocol
Our DePIN Fee Abstraction Layer eliminates gas friction for end-users, enabling seamless onboarding and predictable operational costs for your network. We deliver production-ready infrastructure, not just concepts.
01
Gasless Transaction Sponsorship
End-users interact with your DePIN network without holding native tokens. We sponsor gas fees via meta-transactions, removing the #1 barrier to adoption. Integrates with Account Abstraction (ERC-4337) wallets.

Frequently Asked Questions on DePIN Fee Abstraction
Get clear answers on how our DePIN Fee Abstraction Layer integrates, scales, and drives user growth for your network.
Our layer acts as a smart contract middleware deployed on your DePIN's native chain. It intercepts user transactions requiring network fees (e.g., for data writes, device interactions), validates a sponsored payment method (like a credit card via Stripe or a stablecoin), and pays the gas fees on the user's behalf. The core protocol uses meta-transactions with signature verification and secure relayers, abstracting the entire crypto payment flow from the end-user.
