CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 veterans.

We architect and deploy audit-ready smart contracts on Ethereum, Solana, and EVM-compatible L2s. Our process ensures gas-optimized, upgradeable, and secure code from day one.

Reduce your time-to-market from months to weeks with our battle-tested development framework.

  • Custom Logic: ERC-20/721/1155, DeFi protocols, DAOs, and bespoke business logic.
  • Security-First: Built with OpenZeppelin libraries and formal verification patterns.
  • Full Lifecycle: Development, testing, deployment, and post-launch maintenance with 99.9% uptime SLA.

We deliver production-grade smart contracts that power real-world applications, not just proofs-of-concept. Get a secure foundation for your token, NFT collection, or DeFi protocol.

ARCHITECTURE & EXECUTION

Core Technical Capabilities

We deliver production-ready, secure cross-chain NFT membership infrastructure. Our modular approach ensures rapid deployment and seamless integration with your existing systems.

01

Multi-Chain Smart Contract Development

Custom ERC-721/1155 contracts with cross-chain extensions (CCIP, LayerZero). We implement gas-optimized minting, soulbound logic, and upgradeable proxy patterns for future-proofing.

Frequently Asked Questions

Get clear answers on timelines, costs, security, and support for your NFT membership bridge project.

A standard cross-chain NFT membership bridge from specification to mainnet deployment typically takes 4-8 weeks. This includes 1-2 weeks for architecture design and security planning, 2-4 weeks for core smart contract development and internal testing, and 1-2 weeks for third-party audit integration and final deployment. Complex multi-chain integrations or custom governance features can extend this timeline, which we scope and agree upon before project kickoff.
