Last year, my team and I decided to create a metaverse social platform focusing on 'multi-chain user interaction'—the core idea is to allow users from different public chains to interact in the same virtual space. For example, Ethereum users can bring their NFT avatars and participate in virtual parties with Solana users, and they can also gift on-chain assets to each other. However, we hit a roadblock in the early stages of development: the NFT metadata formats of different public chains are not compatible, and Ethereum's 3D avatars cannot be displayed properly on Solana users' interfaces. Users wanting to gift tokens across chains have to exit the platform to switch wallets, leading to a particularly fragmented experience. After three months of development, the core 'multi-chain interaction' feature had not yet been implemented, and the team was at a loss. It wasn't until our technical partner learned about Boundless Network's cross-chain development kit at an industry salon that we approached it with a trial mindset, and unexpectedly, it completely broke down the interactive barriers of multi-chain scenarios.
At the beginning, our most urgent need was to solve the issue of 'interoperability of multi-chain NFTs.' The technical team at Boundless Network helped us integrate the 'cross-chain NFT adaptation SDK.' This SDK can automatically convert the metadata formats of NFTs from different public chains—whether it is the ERC-721 standard on Ethereum or the SPL standard on Solana, it can be uniformly adapted to the virtual scenes of our platform after integration. During the first test, I logged in with my Ethereum wallet and loaded my 3D NFT avatar, while my colleague using a Solana wallet entered the virtual room simultaneously. Not only did they clearly see the details of my avatar, but they could also click on the avatar to view the on-chain information of the NFT; conversely, when my colleague set a 2D illustration NFT from Solana as their avatar, I could also see it normally without any lag or format distortion. At that moment, we finally saw the possibility of 'multi-chain user interaction on the same screen.'
Next, the implementation of the 'cross-chain asset gifting' feature has enhanced the social attributes of the platform. Previously, we wanted users to mutually send tokens at virtual parties, but we could only guide them to jump out of the platform and operate on other cross-chain tools, which many users found troublesome and gave up. With the help of Boundless Network's 'embedded cross-chain interface,' we directly integrated the cross-chain functionality into the platform's 'gift box' module: if a user wants to send USDT to friends on other chains, they just need to select 'cross-chain gifting' in the gift box, enter the recipient's platform ID (without manually inputting complex wallet addresses), and the system will automatically recognize the recipient's frequently used public chain, recommend the optimal cross-chain route, and allow custom gift messages. In the first week of launch, there were over 1,200 records of cross-chain asset gifting, and a user in the community said, 'No need to switch back and forth, just a few clicks in the virtual room can send gifts, it's so convenient.'
What surprised us even more is that Boundless Network's 'multi-chain data synchronization' feature has helped us solve the challenges of user operations. Previously, user data from different public chains was isolated, and the activity levels of Ethereum users and the asset holdings of Solana users had to be counted separately, making it impossible to conduct unified operational activities. However, through the platform's data middle office, we can synchronize the behavioral data of all on-chain users in real-time, such as 'a certain user holds 3 NFTs on the Ethereum chain and has participated in 2 virtual activities on the Base chain,' based on which we can push personalized content to users—recommending virtual outfit activities for NFT holders and cross-chain asset reward tasks for high-frequency interacting users. In March of this year, we held a 'multi-chain user team challenge' activity where users could team up across chains, and upon completing tasks, they could receive cross-chain NFT rewards, with the number of participants exceeding 50,000, three times the participation of previous single-chain activities.
Now, our metaverse social platform has adapted to 8 mainstream public chains, with registered users surpassing 300,000, among which 40% of users actively initiate cross-chain interactions. The platform's average daily online duration has also increased from the initial 20 minutes to 45 minutes. Many NFT projects have proactively approached us for collaboration, wanting to use our platform to hold cross-chain virtual exhibitions for their holders across different chains, which has also shown us the commercial potential of the platform.
For our team, Boundless Network has not only provided cross-chain technology but has also helped us realize the initial concept of 'multi-chain metaverse social'—allowing users from different public chains to interact freely and share assets in virtual spaces without being restricted by chain barriers. In the future, we plan to utilize the platform's RWA cross-chain services to tokenize offline concert, exhibition, and other event scenarios, crossing them into the multi-chain metaverse, allowing users to participate in virtual sub-venues of offline events; we also look forward to the platform supporting more public chains that accommodate 3D assets, making our metaverse scenes richer and attracting more users to join this 'boundary-less social interaction.'@Boundless
