Multi-Network NFT Marketplace Wallet Plugin

A plug-and-play wallet module that enables NFT marketplaces to support listings, purchases, and collections spanning multiple blockchain ecosystems from a single user wallet interface.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the foundation of your protocol. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment to EVM or Solana.

  • From Specification to Mainnet: We handle the full lifecycle—design, development, testing, and deployment—ensuring gas efficiency and upgradeability.
  • Security as Standard: Every contract undergoes static analysis, formal verification, and peer review to mitigate risks before audit firms like CertiK or Quantstamp.
  • Protocol Integration: Seamlessly connect your contracts with oracles, bridges, and decentralized storage for a fully functional dApp.

Deliver a secure, auditable, and performant smart contract suite in 4-6 weeks, reducing your technical risk and accelerating time-to-market.

Frequently Asked Questions

Common questions from CTOs and product leads about integrating a secure, multi-chain NFT wallet plugin.

A standard multi-network NFT wallet plugin with core features (connect, view, transfer) takes 2-4 weeks from kickoff to production deployment. Complex integrations, such as adding batch operations, custom chain support, or advanced security modules, can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial scoping call.
