Core Components of Our Gasless Sponsorship System
A modular, enterprise-grade system designed to abstract gas fees from your users, removing the primary barrier to Web3 adoption. Each component is built for security, scalability, and seamless integration.
Smart Contract Relayer Network
Our decentralized network of relayers submits and pays for user transactions on-chain. Built with EIP-2771 and ERC-2771 standards for secure meta-transactions, ensuring user intent is preserved and gas sponsorship is trustless.
Paymaster Abstraction Layer
Flexible payment logic that allows you to sponsor gas fees in native tokens or stablecoins. Supports ERC-20 and ERC-4337 (Account Abstraction) standards, enabling complex sponsorship rules and subscription models.
User Operation Bundler
High-performance service that aggregates user-signed operations into single transactions, drastically reducing gas costs per user action. Optimized for speed and cost-efficiency on Ethereum L2s and sidechains.
Policy & Rate-Limit Engine
Granular control over who gets sponsored and how much. Define rules based on user tier, transaction type, or daily caps. Prevents abuse and manages your gas budget predictably with real-time analytics.
Developer SDK & APIs
Comprehensive toolkit for seamless integration. Includes client SDKs for React, Unity, Unreal Engine, and RESTful APIs for backend services. Get your game or dApp live with gasless UX in under 2 weeks.
Security & Audit Framework
Every component undergoes rigorous security review. Our smart contracts are audited by leading firms and follow OpenZeppelin best practices. Includes monitoring, alerting, and multi-sig administration for enterprise-grade safety.
Business Outcomes for Game Studios
Implementing gasless transactions isn't just a feature—it's a strategic lever for growth. See the tangible business metrics our sponsorship infrastructure delivers.
Boost Player Onboarding
Remove the #1 friction point for new users. Eliminate the need for players to purchase and manage native tokens before playing, leading to a 90%+ reduction in drop-off at the sign-up stage.
Increase Session Depth & Retention
Enable frictionless micro-transactions for in-game actions like crafting, trading, or upgrades. Players engage more deeply without worrying about transaction costs, directly improving Daily Active User (DAU) and session length metrics.
Monetize Through Premium Models
Shift from pay-to-play to sustainable Web3 models. Sponsor gas for all players and monetize via NFT sales, premium subscriptions, or marketplace fees. We handle the complex sponsorship logic and reimbursement.
Guaranteed Infrastructure Reliability
Focus on game design, not node ops. Our sponsored transaction relayer network offers a 99.9% uptime SLA, automatic failover, and real-time analytics so you never miss a player's action.
Reduce Operational Complexity
We manage the entire gas sponsorship lifecycle: multi-chain paymaster contracts, real-time fraud detection, detailed cost analytics, and automated reimbursement. Deploy a production-ready system in under 2 weeks.
Build vs. Buy: Implementing Gasless Transactions
A detailed comparison of the costs, risks, and time commitments between developing a gasless transaction system internally versus leveraging Chainscore's managed service.
| Factor | Build In-House | Chainscore Managed Service |
|---|---|---|
Time to Initial Deployment | 4-6 months | 2-4 weeks |
Initial Development Cost | $150K - $300K+ | $25K - $75K |
Smart Contract Security Audit | Required (Adds $30K-$80K & 4-8 weeks) | Included & Pre-Audited |
Ongoing Infrastructure & Maintenance | DevOps team & cloud costs (~$5K/month) | Fully Managed (Included) |
Paymaster & Relayer Management | Your team's operational overhead | Automated & Monitored 24/7 |
Multi-Chain Support (EVM) | Custom integration per chain | Native support for 10+ chains |
Developer Experience (SDK/API) | Build from scratch | Production-ready SDK & comprehensive docs |
Uptime & Reliability SLA | Your responsibility | 99.9% Guaranteed |
Total Cost of Ownership (Year 1) | $210K - $476K+ | $25K - $75K |
Strategic Focus | Diverts core team to infrastructure | Enables focus on core product & users |
Our Delivery Methodology for Paymaster Integration
A structured, four-phase process designed to deliver a production-ready gasless experience for your players in weeks, not months. We focus on security, performance, and seamless integration from day one.
Discovery & Architecture Design
We conduct a deep-dive workshop to analyze your game's transaction patterns, user flows, and economic model. The outcome is a tailored Paymaster architecture with defined sponsorship rules, cost models, and security parameters.
Smart Contract Development & Auditing
Our engineers build custom, gas-optimized Paymaster contracts using Solidity 0.8+ and OpenZeppelin libraries. Every contract undergoes a mandatory internal security review before being submitted for a formal audit with partners like Spearbit or Code4rena.
Relayer Infrastructure Deployment
We deploy and configure our high-availability relayer network with automatic failover, ensuring 99.9% uptime for sponsoring user transactions. This includes setting up monitoring, alerting, and integration with your backend for real-time policy enforcement.
Integration, Testing & Go-Live
We provide SDKs and comprehensive documentation for your frontend and backend teams. The phase includes load testing, user acceptance testing (UAT), and a staged rollout plan to ensure a smooth launch of the gasless experience for your players.

Gasless Transaction Sponsorship: Key Questions
Get clear answers on how Chainscore Labs implements and manages gasless transactions to remove friction for your players.
We deploy a secure, custom Paymaster smart contract on your target chain (EVM-compatible). This contract holds a balance of the native token (e.g., ETH, MATIC) and automatically pays the gas fees for transactions initiated by your approved users. Players sign meta-transactions, which our off-chain relayer network submits and sponsors, making the experience completely gas-free for the end user. We provide a dashboard for you to monitor and top up the sponsor wallet.
