Legacy Contract Gas Efficiency Migration

We refactor and migrate your older, gas-inefficient smart contracts to modern, optimized patterns and compiler versions, preserving all functionality while slashing transaction costs.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production on EVM and Solana.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built for security and scale from day one.

  • Production-Ready Code: Built with Solidity 0.8+ or Rust, leveraging battle-tested libraries like OpenZeppelin.
  • Security-First: Every contract undergoes rigorous internal audits before deployment, with optional third-party audit coordination.
  • Gas Optimization: We write for efficiency, targeting up to 40% lower gas costs for end-users.

We don't just write code; we deliver the secure, audited foundation your dApp needs to launch with confidence.

Our full-service development includes:

  • Token Standards: ERC-20, ERC-721, ERC-1155, and SPL token implementations.
  • DeFi Primitives: Custom vaults, staking pools, lending logic, and automated market makers (AMMs).
  • Upgradeable Architecture: Proxies and diamond patterns (EIP-2535) for future-proof systems.
  • Full Deployment & Verification: We handle mainnet deployment and block explorer verification.

PROVEN METHODOLOGY

Our Migration & Refactoring Process

A systematic, security-first approach to modernizing your legacy smart contracts. We deliver audited, gas-optimized code with zero downtime, ensuring your protocol's integrity and user trust remain intact.

TANGIBLE ROI

Business Outcomes of Gas Optimization

Migrating legacy contracts for gas efficiency delivers measurable improvements to your bottom line and user experience. We focus on outcomes, not just code changes.

01

Reduced Transaction Costs

Directly lower the cost of every user interaction. We achieve 50-90% gas savings on core functions by refactoring storage patterns, logic, and leveraging modern compiler optimizations.

Improved User Retention

Lower fees and faster transactions directly improve user satisfaction and retention. We eliminate gas-related friction that causes drop-offs during critical actions like minting, swapping, or staking.

Enhanced Protocol Competitiveness

A gas-efficient contract is a market advantage. Attract more users and liquidity by offering lower fees than competitors, directly impacting your Total Value Locked (TVL) and adoption metrics.

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that power your dApp's core logic. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and formal verification to mitigate risks before deployment.

  • End-to-End Development: From ERC-20/721/1155 tokens to complex DeFi protocols and DAO governance systems.
  • Security & Audits: Rigorous internal review, automated testing with Hardhat/Foundry, and preparation for third-party audits.
  • Gas Optimization: We write efficient Solidity 0.8+ code to minimize transaction costs for your users.
  • Mainnet Deployment & Verification: Full support for deployment, Etherscan verification, and initial monitoring setup.

Deliver a secure, auditable, and performant smart contract foundation in as little as 2-4 weeks for an MVP.

Technical & Process Questions

Legacy Contract Migration FAQs

Answers to common questions about migrating your existing smart contracts to more gas-efficient implementations. Based on our experience with 50+ migration projects securing over $500M in TVL.

A standard migration from audit to mainnet deployment takes 2-4 weeks. This includes: 1 week for code analysis and planning, 1-2 weeks for development and internal testing, and 1 week for client review and final deployment. Complex protocols with extensive state or multi-chain deployments may require 6-8 weeks. We provide a detailed project plan with milestones at kickoff.
