ENTERPRISE-GRADE FEATURES

Core Protocol Capabilities We Deliver

Our fee delegation protocol development delivers production-ready infrastructure with measurable performance and security guarantees, built for high-volume FinTech and Web3 applications.

Gas Abstraction & Sponsorship

Deploy user-friendly dApps where transaction fees are paid by the application, not the end-user. We implement ERC-2771 and ERC-4337 standards for seamless, gasless experiences that drive adoption.

MEASURABLE RESULTS

Business Outcomes of a Custom Fee Delegation Protocol

A tailored fee delegation protocol is more than a feature—it's a strategic asset that directly impacts user acquisition, operational costs, and market competitiveness. Here are the concrete outcomes you can expect.

Zero-Friction User Onboarding

Eliminate the primary barrier to entry for new users by covering their gas fees. This leads to a 70-90% increase in first-time transaction completion rates and significantly faster user base growth.

70-90%

Higher Conversion

Gas Cost for Users

Reduced Operational & Support Costs

Automate gas sponsorship for specific actions (e.g., first mint, governance vote) with programmable rules. This cuts manual support overhead and reduces customer acquisition cost (CAC) by streamlining the user journey.

40-60%

Lower Support Tickets

Automated

Sponsorship Rules

Enhanced Protocol Security & Control

Implement secure, non-custodial architectures using meta-transactions or paymasters (ERC-4337). Our development includes formal verification and audits to prevent subsidy abuse and protect your treasury.

Security Standard

Competitive Market Differentiation

Offer a superior user experience that competitors without fee abstraction cannot match. This becomes a key feature in marketing and a defensible moat, attracting both users and developers to your ecosystem.

METHODOLOGY

Our Protocol Development Process

A structured, security-first approach to building robust, production-ready fee delegation protocols that accelerate your time-to-market and ensure long-term reliability.

Architecture & Design

We design modular, gas-efficient protocol architectures using battle-tested patterns like EIP-2771 for meta-transactions and EIP-2612 for gasless approvals. This ensures your protocol is scalable and future-proof from day one.

2-3 weeks

Design Phase

Smart Contract Development

Our engineers write clean, auditable Solidity 0.8+ code with OpenZeppelin libraries. We implement core delegation logic, fee management, and secure upgrade paths using transparent proxies (UUPS).

> 95%

Test Coverage

Security & Auditing

Every line of code undergoes rigorous internal review followed by a formal audit from a leading security firm like Trail of Bits or ConsenSys Diligence. We provide a comprehensive vulnerability report and remediation plan.

2 Audits

Standard

Testing & Simulation

We deploy to testnets (Sepolia, Holesky) and run extensive simulations using Foundry and Hardhat. This includes stress testing under high load, edge-case validation, and gas consumption profiling.

Deployment & Mainnet Launch

We manage the secure deployment to Ethereum Mainnet or your chosen L2 (Arbitrum, Optimism, Base). This includes multi-sig wallet setup, contract verification on Etherscan, and initial parameter configuration.

Monitoring & Maintenance

Post-launch, we provide 24/7 monitoring with alerts for failed transactions or anomalous fee patterns. We offer ongoing support for upgrades, parameter tuning, and integration of new EIPs.
