Gas Abstraction Migration for Legacy dApps

A managed service to audit, plan, and execute the migration of your existing dApp from traditional fee models to modern gas abstraction, ensuring zero disruption for live 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 backbone of your Web3 application. Our development process is built on Solidity 0.8+ and OpenZeppelin standards, ensuring security and interoperability from day one.

Deliver a battle-tested, gas-optimized contract suite in as little as 2-4 weeks.

Our full-cycle development includes:

  • Architecture & Design: Specification of tokenomics, access control, and upgrade paths.
  • Implementation: Development with ERC-20, ERC-721, ERC-1155, and custom logic.
  • Security Audits: Rigorous internal review and integration with leading audit firms.
  • Deployment & Verification: Mainnet deployment on EVM-compatible chains with full source code verification.

We focus on real-world outcomes: reducing gas costs by 30-50%, implementing secure upgrade patterns like TransparentProxy, and ensuring compliance with regulatory frameworks for tokenized assets.

PROVEN METHODOLOGY

Our End-to-End Migration Framework

We execute a structured, low-risk migration process that minimizes downtime and ensures your dApp's core logic and user experience remain intact.

01

Architecture & Smart Contract Audit

We perform a deep-dive analysis of your existing smart contracts and system architecture to identify dependencies, vulnerabilities, and gas optimization opportunities before migration begins.

100%
Code Coverage Analysis
Zero Critical Bugs
Post-Audit Guarantee
02

Gas Abstraction Layer Development

We design and deploy a custom Paymaster and ERC-4337 Account Factory, enabling gasless transactions for your users while you maintain control over sponsorship rules and billing.

Business Outcomes of a Successful Migration

Migrating your legacy dApp to a modern gas abstraction solution delivers concrete business advantages, from immediate user growth to sustainable operational efficiency.

01

User Acquisition & Retention

Eliminate the onboarding friction of native gas tokens. New users can interact with your dApp using stablecoins or credit cards, increasing conversion rates and reducing drop-off by up to 70%.

Our 4-Phase Migration Process

A structured, low-risk approach to move your dApp from native gas to seamless user-paid transactions. We provide a fixed-scope, milestone-driven plan with clear deliverables at each stage.

01

Phase 1: Architecture Audit & Strategy

We conduct a deep technical analysis of your existing smart contracts and frontend. You receive a detailed migration blueprint with cost projections, risk assessment, and a phased implementation roadmap.

Gas Abstraction Migration FAQs

Answers to the most common questions from CTOs and technical leads planning a gas abstraction migration for their legacy dApp.

Our standard migration follows a 4-phase process, typically completing in 3-6 weeks.

  1. Audit & Architecture (1 week): We conduct a full code review of your existing contracts and design the new gasless architecture.
  2. Development & Integration (2-4 weeks): We implement the chosen solution (ERC-4337 Account Abstraction, Gas Station Network, or custom relayers) and integrate with your frontend.
  3. Testing & Security (1 week): Rigorous testing on testnets, including integration tests and a final security review by our internal audit team.
  4. Deployment & Go-Live (1-2 days): Coordinated mainnet deployment and monitoring setup.

Timeline varies based on dApp complexity and the chosen abstraction model.
