CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From token standards to complex DeFi logic, we deliver contracts that are secure, scalable, and ready for mainnet.
- Full Lifecycle Development: Strategy, architecture, coding (
Solidity/Rust), testing, and deployment. - Security-First Approach: Mandatory audits using tools like Slither and MythX, plus integration with OpenZeppelin libraries.
- Gas Optimization: Every line of code is reviewed for efficiency, targeting 20-40% lower transaction costs.
- Real-World Ready: Includes upgradeability patterns, multi-sig admin controls, and comprehensive event logging.

PROVEN METHODOLOGY
Our Migration Framework
A systematic, security-first process for migrating NFT identity and metadata from legacy platforms to Flow. We deliver predictable timelines, zero data loss, and production-ready contracts.
01
Discovery & Architecture
We analyze your existing NFT collection, metadata schema, and smart contract logic to architect a migration blueprint. This includes mapping token IDs, traits, and ownership data to Flow's Cadence model.

Technical & Process Questions
Flow NFT Identity Migration FAQs
Get clear, specific answers to the most common questions about migrating your NFT identity system to Flow. We cover timelines, costs, security, and our proven methodology.
A standard migration for a collection of 10,000 NFTs with core metadata and on-chain traits takes 3-5 weeks from kickoff to mainnet deployment. This includes 1 week for architecture and smart contract development, 1-2 weeks for data migration and testing, and 1 week for final audits and deployment. Complex projects with custom logic, multi-chain bridging, or large-scale collections (100K+) may extend to 8-12 weeks.
