CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Custom Tokenomics: Design and deploy
ERC-20,ERC-721, andERC-1155tokens with vesting, staking, and governance modules. - DeFi & DEX Logic: Build automated market makers (AMMs), liquidity pools, and yield strategies.
- Security-First Process: Every contract undergoes internal review and is prepared for third-party audits from firms like CertiK or Quantstamp.
We guarantee functional correctness and security best practices, reducing your time-to-audit by weeks and mitigating critical risks before mainnet deployment.

A STRUCTURED APPROACH
Our Proven Migration Methodology
We follow a rigorous, four-phase framework designed to de-risk your legacy system migration, ensure data integrity, and deliver a production-ready blockchain solution on schedule.
01
Discovery & Architecture Design
We conduct a deep-dive analysis of your existing data models, APIs, and business logic. We then design a target blockchain architecture (e.g., EVM, Solana, Cosmos) with optimized data schemas and smart contract interfaces.

Legacy System Migration: Key Questions
Answers to the most common technical and operational questions CTOs ask when evaluating a blockchain migration partner.
Our proven 4-phase process delivers production-ready systems in 4-8 weeks. Phase 1 (1-2 weeks) is a technical audit and architecture design. Phase 2 (2-3 weeks) involves core smart contract development and data mapping. Phase 3 (1-2 weeks) is integration testing and security review. Phase 4 (1 week) is deployment and handover. We provide a fixed-scope timeline after the initial audit.
