We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process is built for security and speed, delivering a production-ready MVP in as little as 2 weeks.
AppChain & Layer 3 Sponsorship Solution Design
Smart Contract Development
Secure, audited smart contract systems built for production at scale.
- Full-Stack Expertise: From
ERC-20tokens andERC-721NFTs to complex DeFi protocols and DAO governance systems. - Security-First Development: Built on
Solidity 0.8+withOpenZeppelinlibraries and internal audit patterns before formal review. - Measurable Outcomes: Achieve >99.9% uptime, gas-optimized transactions, and modular code for future upgrades.
We don't just write code; we deliver the secure, auditable digital agreements your business runs on.
Core Components of a First-Principles Sponsorship Design
We design your AppChain or Layer 3 sponsorship system from the ground up, focusing on security, scalability, and developer experience. Each component is engineered for production readiness.
Gas Abstraction & Paymaster Integration
Seamless integration of ERC-4337 Account Abstraction and custom Paymaster contracts. We handle gas sponsorship logic, user onboarding, and fee management so your users never need native tokens.
Multi-Chain Relayer Infrastructure
Deploy a high-availability relayer network with automatic failover and load balancing. We ensure sub-second transaction propagation and 99.9% uptime for your sponsored transactions.
Policy Engine & Fraud Prevention
Implement granular sponsorship policies (whitelists, rate limits, spend caps) with real-time fraud detection. Our systems prevent Sybil attacks and manage operational costs.
Developer SDK & API
Receive a production-ready SDK (TypeScript/Python) and REST APIs for easy integration. Includes documentation, code samples, and webhook support for event-driven workflows.
Analytics & Cost Dashboard
Gain full visibility with a custom dashboard tracking gas spend, user adoption, transaction success rates, and ROI. Make data-driven decisions to optimize your sponsorship strategy.
Security Audit & Deployment
Our sponsorship smart contracts undergo rigorous security audits following OpenZeppelin standards. We manage the full deployment lifecycle on your chosen L2 or AppChain.
Business Outcomes of a Custom Sponsorship Architecture
Our sponsorship architecture design delivers concrete, quantifiable improvements to your core business metrics, moving beyond technical features to drive real growth.
Eliminate User Onboarding Friction
We design and implement gas sponsorship and session key systems that remove the need for users to hold native tokens, increasing conversion rates by up to 40% for new user actions.
Predictable & Scalable Cost Structure
Replace volatile, user-borne gas fees with a fixed, enterprise-managed operational expense. Our architecture provides real-time analytics and cost controls for predictable scaling.
Enhanced Security & Compliance Posture
Implement audited, non-custodial sponsorship contracts with configurable policies (spend limits, allowlists). Maintain full user sovereignty while mitigating protocol risk.
Accelerated Time-to-Market
Leverage our battle-tested, modular sponsorship frameworks for AppChains and L3s. Deploy a production-ready system in weeks, not months, with full integration support.
Superior Developer Experience
Provide your engineering team with simple SDKs and clear APIs for managing sponsorship flows. Reduce internal development overhead and focus on core product logic.
Sustainable Competitive Advantage
A tailored sponsorship model becomes a core product differentiator, locking in user loyalty and creating defensible moats through superior UX and economic alignment.
Custom Design vs. Generic Paymaster: A Strategic Comparison
A detailed comparison of building a custom, application-specific paymaster versus using a generic, one-size-fits-all solution. This table highlights key operational, financial, and strategic factors critical for CTOs and product leads.
| Key Factor | Generic Paymaster | Custom Paymaster Design |
|---|---|---|
Architecture Alignment | ||
Gas Abstraction Logic | Fixed, rigid rules | Programmable & dynamic |
User Onboarding Friction | High (wallet prompts) | Zero (sponsored UX) |
Cost Efficiency | Low (pays for unused ops) | High (optimized for your app) |
Time to Implement | < 1 week | 2-4 weeks |
Security & Audit Surface | Shared risk (public contract) | Isolated, audited specifically for you |
Custom Business Logic | Not possible | Full support (e.g., subscription gating, loyalty) |
Ongoing Maintenance | Vendor-managed | Optional SLA from Chainscore |
Typical Annual TCO | $10K - $50K+ in fees | $50K - $150K (design + optional ops) |
Strategic Control | Vendor-locked | You own the contracts & strategy |
Our Methodology for Sponsorship System Design
We deliver production-ready, gas-efficient sponsorship systems through a structured, security-first development lifecycle designed for AppChains and Layer 3s.
Architecture & Strategy Session
We analyze your tokenomics, user flows, and chain architecture to design a sponsorship model that aligns with your business goals and technical constraints.
Smart Contract Development
Build secure, auditable sponsorship contracts in Solidity/Vyper using OpenZeppelin libraries. Features include paymaster integration, batch processing, and multi-token support.
Security Audit & Formal Verification
Every contract undergoes rigorous internal review and optional third-party audits (e.g., CertiK, Halborn) to ensure fund safety and logic correctness before mainnet deployment.
Integration & Deployment
We handle the end-to-end deployment of your sponsorship system, including paymaster configuration, RPC endpoint setup, and integration with your existing dApp frontend and backend.
Monitoring & Analytics Dashboard
Gain real-time visibility into sponsorship usage, gas expenditure, and user adoption with our custom Grafana dashboards and alerting systems.
Ongoing Support & Optimization
We provide continuous support, gas fee optimization updates, and feature enhancements based on network upgrades and your evolving product needs.
Frequently Asked Questions on AppChain Sponsorship
Get clear answers on timelines, costs, and technical requirements for launching your dedicated blockchain with Chainscore's sponsorship solution.
A standard AppChain deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for architecture design and tokenomics, 2-3 weeks for core development and testing, and 1-2 weeks for security audits and final deployment. We provide a detailed Gantt chart at project inception.
