NFT Aggregator Cross-Chain Messaging
Frequently Asked Questions
Common questions from CTOs and technical leads about integrating cross-chain messaging into NFT marketplaces and aggregators.
A standard integration takes 4-6 weeks from kickoff to production deployment. This includes protocol selection (e.g., LayerZero, Axelar, Wormhole), smart contract development, security audit, and testnet validation. Complex multi-chain logic or custom bridging mechanisms can extend this to 8-10 weeks. We provide a detailed project plan within the first week of engagement.
