The problem Xstro: Game of Memes solves

1. Skin-to-Earn (Staking NFTs as game skins)
   NFT holders can stake their NFTs as skins in our game to earn token airdrops, adding a new gaming utility for NFTs. Currently, we have over 1800 NFT stakers with 6800 NFTs staked, totaling $28M in value, surpassing Blur and Paraspace in the number of NFTs staked.

2. MemeFi
   Meme community members can use their meme avatars as game characters and earn meme tokens, including our $GAME token (https://basescan.org/token/0x8e0e798966382e53BFb145d474254CbE065c17dc).
   We've collaborated with and integrated several meme projects such as Brett, Toshi, AYB, Daddy, DOG, and Zack into our game. The memecoin communities can engage in community battles and earn rewards.

3. Web3 IP-as-a-service (Promotion of Web3,Base and meme Culture)
   Games typically don't solve industry problems, but we strive to provide utility for NFTs and memes. We're also pioneering Web3 IP-as-a-service to promote Web3,Base and meme culture to gamers worldwide.

Daily quests encourage players to engage with various Base projects like Brett, Degen, and AYB to earn rewards. We introduce the Web3 Premier League concept through the Game Cup, allowing different Web3 communities to compete in a premier league format. Through our game, many gamers may learn more about the Base ecosystem, Web3 and meme culture.

Challenges I ran into

1. Integration of blockchain features into Unity
   Typically, integrating blockchain features such as wallet integration into Unity is handled by the game developer rather than the blockchain engineer. However, game developers often lack familiarity with blockchain features.

This results in prolonged coordination between game developers and blockchain developers for these integrations. However, we still successfully integrated on-chain features like staking NFT as game skins, $GAME token launch, token airdrop and claim function through merkle tree. And we are going to integrate more on-chain features.

2. Web version vs App version
   Initially, we aimed to provide a web version as it is more accessible and secure for crypto users. However, as a multiplayer game, WebGL has inherent latency and server stability issues. Consequently, we had to shift to developing an app version after spending significant time on the web version, leading to increased development costs.

Currently, we have submitted both the web and app versions for Onchain Summer.
