The Infrastructure Decision
Build vs. Buy: Fee Abstraction Layer
Compare the total cost, risk, and time investment of developing a gas sponsorship system in-house versus using Chainscore's production-ready solution.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production | 4-9 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Smart Contract Security | High Risk (Requires audit) | Low Risk (Pre-audited, battle-tested) |
Ongoing Maintenance | Dedicated DevOps & Dev Team | Fully Managed Service |
Protocol Coverage | Custom, limited scope | EVM, Solana, 15+ chains |
Paymaster Flexibility | Fixed logic, hard to modify | Fully customizable sponsorship rules |
User Experience Features | Basic | Advanced (Session Keys, Batch TX, Bundling) |
Uptime & Reliability SLA | Your responsibility | 99.9% Guaranteed |
Total Cost of Ownership (Year 1) | $300K - $750K+ | $50K - $150K |

PROVEN PROCESS
Our Delivery Methodology
A structured, four-phase approach designed to deliver production-ready fee abstraction layers with security, speed, and scalability at the core.
01
Discovery & Architecture
We begin with a deep technical audit of your existing dApp and tokenomics. We define the optimal fee model (sponsored, pay-with-token, or hybrid) and architect the smart contract system using battle-tested patterns from OpenZeppelin and Solmate.

Smart Contract Development
Our engineers write, test, and optimize the core abstraction contracts (ERC-4337 Account Factory, Paymasters, Relayers). Every line is peer-reviewed and undergoes static analysis with Slither and Foundry fuzzing before deployment.

CORE INFRASTRUCTURE
Blockchain Infrastructure Development
Build and scale secure, high-performance blockchain infrastructure tailored for your Web3 application.
We architect and deploy the foundational infrastructure your dApp needs to operate at scale. Our team handles the complex backend so you can focus on product and user experience.
- Custom RPC Node Clusters: High-availability setups for
EVMandSolanawith 99.9% uptime SLAs. - Indexing & Data Pipelines: Real-time blockchain data ingestion and structured APIs for on-chain analytics.
- Validator & Staking Services: Secure, non-custodial node operations for
Ethereum,Cosmos, and other PoS networks.
We deliver production-ready infrastructure in 2-4 weeks, eliminating months of DevOps overhead and reducing your cloud costs by up to 40%.
Our approach is built on security-first principles, utilizing infrastructure-as-code (Terraform, Ansible) and comprehensive monitoring (Prometheus, Grafana) to ensure reliability and performance from day one.
Fee Abstraction & UX
Frequently Asked Questions
Get clear answers on how our dApp Fee Abstraction & UX Layer service works, from implementation to ongoing support.
Fee abstraction is the mechanism that allows your users to interact with your dApp without needing to hold the blockchain's native token (like ETH for gas). This is critical for user growth because it removes the single biggest onboarding friction: requiring users to first acquire and manage gas tokens. By implementing our UX layer, you can sponsor transactions, accept stablecoin payments for fees, or use meta-transactions, leading to a 70-90% reduction in user drop-off during the first transaction.
