ENTERPRISE-GRADE INFRASTRUCTURE
Core Capabilities of Our Subscription Sponsorship Engine
A purpose-built engine that handles the complexity of Web3 subscription billing, enabling your product to offer seamless, gasless user experiences while you maintain predictable revenue.
01
Gasless Transaction Sponsorship
We sponsor all gas fees for your users' subscription actions—sign-ups, renewals, and upgrades—removing the primary friction point for mainstream adoption. No more requiring users to hold native tokens.

THE VALUE OF FEE SPONSORSHIP
Business Outcomes: Predictable Costs, Better UX, Higher Retention
Subscription-based fee sponsorship isn't just a technical feature—it's a product strategy. By abstracting away gas fees, you unlock predictable operational costs and a seamless user experience that directly drives growth and retention.
01
Predictable & Scalable Cost Structure
Replace volatile, user-paid gas fees with a fixed monthly subscription. This transforms your cost of acquisition (CAC) and user onboarding from an unpredictable variable into a stable, scalable line item, enabling accurate financial forecasting and unit economics.

For End Users
02
Frictionless User Onboarding
Eliminate the #1 barrier to entry for mainstream users: needing native tokens for gas. Users can sign and execute transactions with a single click, no wallet funding required. This reduces drop-off rates and accelerates user activation.

Higher User Retention & Engagement
A seamless, fee-free experience keeps users coming back. By removing the cognitive and financial friction of gas payments, you encourage more frequent interactions, higher session times, and stronger product stickiness.

Architectural Comparison
Subscription Sponsorship vs. Traditional Paymaster Models
A technical breakdown of how Chainscore's subscription-based fee sponsorship model provides superior predictability, cost control, and user experience compared to legacy paymaster implementations.
| Feature / Metric | Traditional Paymaster (Gas Station Network) | Chainscore Subscription Sponsorship |
|---|---|---|
Pricing Model | Pay-per-transaction (volatile) | Flat monthly fee (predictable) |
Cost Predictability | Low (tied to gas price spikes) | High (fixed operational cost) |
User Experience | Session keys or per-tx approval | Seamless, gasless interaction |
Developer Overhead | High (integrate & manage relayers) | Low (simple API/SDK integration) |
Multi-Chain Sponsorship | Complex, chain-specific setup | Unified, single subscription |
Custom Sponsorship Rules | Limited to basic whitelists | Advanced (time, amount, NFT-gated) |
Settlement & Reconciliation | Manual, post-hoc | Automated dashboard & reporting |
Typical Time to Integrate | 3-6 weeks | < 1 week |
Annual Cost for 100K Users | $50K - $200K+ (variable) | $24K - $60K (predictable) |

Frequently Asked Questions on Subscription Fee Sponsorship
Get clear answers on how our subscription-based fee sponsorship service works, from implementation to pricing and ongoing support.
We deploy a smart contract system that allows your project to sponsor user transaction fees (gas) on a recurring basis. Users connect their wallets and sign a permission, after which their eligible transactions are automatically paid for from a dedicated sponsor wallet you control. You fund the sponsor wallet via subscription, and we provide the dashboard to monitor usage, set spending limits, and manage user cohorts.
