Gasless Transaction Sponsorship for Players

We implement paymaster systems and meta-transaction protocols that allow game studios to cover network fees, abstracting blockchain complexity for end-users.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the foundation of your Web3 product. Our development process is built for security and audit-readiness from day one, using Solidity 0.8+ and OpenZeppelin libraries to ensure robust, battle-tested code.

Deliver a secure, functional MVP in as little as 2-4 weeks, with full audit support included.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 contracts with tailored minting, vesting, and governance logic.
  • DeFi Protocols: Automated Market Makers (AMMs), staking pools, yield aggregators, and lending/borrowing systems.
  • Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and compliant KYC/AML integration modules.
  • Full Lifecycle Support: From initial architecture and development through to deployment, verification, and post-launch maintenance.

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.

01

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.

02

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.

03

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.

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.

01

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.

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.

01

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.

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.
