The Story

This project aimed to enhance our client's service by implementing token gating and NFT minting with custom metadata, including airdropping NFT collections. The goal was to create a robust system for controlling access to services and minting NFTs across multiple blockchain networks, making digital experiences more secure and engaging.

Our client specializes in creating interactive, immersive experiences for live events, integrating features like polls, chats, VR/AR elements, and social media to foster community engagement during broadcasts.

Challenges

• > Contract Address Validation: Ensuring contract addresses existed on selected networks.

• > Token Ownership Verification: Verifying user access for NFTs with specific attributes.

• > NFT Minting Configuration: Dynamically configuring network types and contract instances.

• > Multi-NFT Minting Functionality: Addressing the absence of bulk minting capabilities.

• > Testing Limitations: Navigating scarcity of test network coins, deprecated test networks, and high costs of using real coins.

The Solution

Our solution implemented contract address validation through Web3, preventing the creation of chat rooms with invalid contracts. We enhanced token ownership verification by adding Enumerable support to the smart contract, streamlining token ID retrieval. For NFT minting, we crafted a provider using ethers for network switching and contract creation. We developed a custom "bulkMintNfts" function for efficient mass minting with custom metadata, and implemented off-chain collection creation to mitigate gas fees. Finally, we integrated a custom event filter to retrieve specific collection token IDs.

The Outcome

The project successfully delivered secure token gating and efficient NFT minting capabilities across multiple networks. This implementation ensured robust access control for service owners while enhancing user engagement through NFT ownership. The solution's resilient design overcame testing challenges, resulting in a cost-effective, production-ready system that significantly elevated our client's blockchain capabilities and user experience value proposition.
