Secure, production-ready smart contracts built by Web3 experts to power your decentralized application.
We architect, develop, and deploy audit-ready smart contracts on EVM and Solana ecosystems. Our code is built with OpenZeppelin standards, gas optimization patterns, and comprehensive test suites to ensure security and efficiency from day one.
Deliver a secure, functional MVP in as little as 2-3 weeks.
ERC-20, ERC-721, staking, vesting, and automated market makers (AMMs).Ownable, Roles, and custom governance modules.We design and deploy modular, secure paymaster systems tailored to your application's unique tokenomics and user experience requirements. Each component is built for performance, security, and seamless integration.
We deploy and manage high-availability relayers to submit user operations, and bundlers to package them for the blockchain. Includes monitoring, failover, and gas price optimization to minimize costs and latency.
Paymaster logic designed for interoperability across EVM chains and Layer 2s (Optimism, Arbitrum, zkSync Era, Base). We handle chain-specific gas mechanics and bridge integrations.
A real-time dashboard to monitor subsidy spending, user adoption metrics, and gas cost trends. Provides APIs for programmatic budget management and detailed reporting.
A generic paymaster is a cost center. A Chainscore-designed, app-specific paymaster is a strategic asset that drives user growth, reduces operational overhead, and creates defensible business models.
We design paymasters that sponsor gas fees for your target users, removing the #1 barrier to onboarding. Drive adoption with seamless, gasless transactions for specific actions like minting, trading, or voting.
Replace unpredictable, volume-based gas sponsorship with a fixed-cost model. We architect paymasters with smart subsidy rules and batch processing to cut your gas overhead by up to 60% versus blanket sponsorship.
Enforce transaction-level policies to prevent abuse and comply with regulations. Our designs include whitelists/blacklists, spend limits, and geo-fencing, giving you full control over sponsored activity.
Monetize your infrastructure. We build paymasters that can sponsor transactions for partner dApps or offer fee-based gas services, turning a cost center into a profit center.
Deploy a high-availability paymaster service with 99.9% uptime SLA, built for your expected TPS. We ensure seamless integration with your stack and automatic failover to prevent user transaction failures.
A bespoke paymaster is a core product differentiator that competitors cannot easily replicate. It creates a superior, frictionless user experience that defines your brand in the market.
A phased approach to paymaster design, from proof-of-concept to production-ready infrastructure with full operational support.

A structured, four-phase approach designed to deliver a secure, scalable, and business-aligned paymaster solution, from initial strategy to full production deployment.
We analyze your AppChain's tokenomics, user flows, and business model to design a custom paymaster architecture. This phase defines sponsorship rules, fee abstraction logic, and integration points with your existing stack.
Our team builds the core paymaster contracts in Solidity/Vyper, implementing gas sponsorship, batch transactions, and whitelist logic. All code undergoes rigorous internal review and is prepared for external security audits.
We integrate the paymaster with your AppChain's RPC endpoints, frontend SDKs, and wallet providers. The system is deployed to a staging environment for comprehensive testing, including load testing and simulated attack vectors.
We manage the mainnet deployment, configure monitoring dashboards for gas usage and sponsorship costs, and provide operational runbooks. Includes 30 days of post-launch support to ensure stability.
Choosing the right gas abstraction infrastructure is critical for user experience and operational cost. This table compares the key differences between a custom-built, app-specific paymaster and using a generic, third-party relayer service.

Common questions from CTOs and technical founders about our specialized paymaster development service.
From initial design to mainnet deployment, a standard AppChain-specific paymaster project takes 3-5 weeks. This includes 1 week for architecture and specification, 2-3 weeks for core development and unit testing, and 1 week for security review and deployment. Complex integrations (e.g., multi-token subsidies, custom sponsor logic) can extend this by 1-2 weeks.
