NFT Upgrade Smart Contract Maintenance

overview

FULL-STACK ENGINEERING

Custom Blockchain Development

End-to-end blockchain solutions from smart contract architecture to full-stack dApp deployment.

We build production-grade blockchain systems tailored to your business logic. Our full-cycle development delivers secure, audited smart contracts on EVM or Solana, integrated with custom frontends and scalable backends.

Smart Contract Development: Solidity/Rust with OpenZeppelin standards and formal verification.
dApp & Frontend: React/Next.js interfaces with ethers.js/wagmi for seamless Web3 interaction.
Backend & Infrastructure: Node.js APIs, indexers, and managed node services for 99.9% uptime.

Go from concept to mainnet in as little as 6-8 weeks with a dedicated engineering pod.

We provide comprehensive technical ownership, including:

Security Audits & Testing: Multi-stage reviews with unit, integration, and fuzz testing.
DevOps & Deployment: CI/CD pipelines, monitoring, and alerting for Ethereum, Polygon, Base, and other L2s.
Post-Launch Support: Ongoing maintenance, upgrades, and performance optimization.
