Legacy Web2 to Web3 Frontend Migration

We refactor and extend your existing web application to integrate blockchain functionality, managing the hybrid state and user transition with minimal disruption.

overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts for DeFi, NFTs, and enterprise applications. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.

  • Full Lifecycle Development: From initial audit-ready code to mainnet deployment and post-launch monitoring.
  • Protocol Integration: Seamless compatibility with ERC-20, ERC-721, ERC-1155, and cross-chain standards.
  • Security-First: Every contract undergoes static analysis, manual review, and is prepared for third-party audits.

Deliver a secure, auditable, and scalable foundation for your Web3 product in as little as 3 weeks.

We focus on measurable outcomes: reducing gas costs by up to 40%, achieving 99.9% uptime post-deployment, and providing clear documentation for your team and users.

A PROVEN METHODOLOGY

Our Migration Development Process

Our systematic, four-phase approach de-risks your Web3 migration, ensuring a secure, scalable, and user-centric frontend delivered on time and within budget.

01

Discovery & Architecture Audit

We conduct a comprehensive analysis of your existing Web2 frontend, user flows, and backend APIs. We map out the optimal Web3 architecture, identifying smart contract interactions, wallet integrations, and data indexing requirements.
