UltraRelay
Remove gas from the critical path
UltraRelay helps teams sponsor fees, support flexible gas payments, and keep smart account transactions moving without forcing users to acquire native tokens first.
Why It Matters
Gas should not block the moment of action
Users should not have to stop, bridge, swap, or acquire native tokens before they can use your product. UltraRelay helps teams move transaction costs into the background so onboarding, trading, deposits, and repeat actions can feel immediate.
Gasless UX
Sponsor gas for first-time users, repeat users, or high-value actions
No Bridging
Let users pay fees with assets they already hold
Reduce User Drop-off
Reduce drop-off in conversion-critical transaction flows
How It Works
One layer for sponsorship, payment, and execution
UltraRelay brings the pieces required to sponsor, price, and execute smart account transactions into one production-ready layer. Teams can design gas experiences around the product flow instead of stitching together separate paymaster and execution services.
Sponsor transaction fees directly
Let users pay fees their way
Align execution with smart accounts, permissions, and orchestration
Product Benefits
A better fee experience for users and operators
Gas sponsorship is a product and economics lever. UltraRelay helps teams reduce first-use friction, control sponsorship rules, and create more predictable transaction experiences.
Instant Activation
Remove the need for native-token setup at the moment of action
Latency Shield
Reduce transaction delays with relay infrastructure built for speed-sensitive embedded wallet and fintech flows.
Sponsorship Policies
Support policy-driven approaches to when sponsorship is allowed
Built for teams that need more than a paymaster endpoint
UltraRelay is strongest as part of the ZeroDev smart account stack. Embedded wallets, permissions, policies, and orchestration all become easier to operate when sponsorship and execution are designed to work together from the start.
