The problem Openverse solves

A metaverse which is chain-agnostic and truly web3.
It aims in solving the

1. Need of cross-chain token transfers for easy liquidity.
2. Cross-chain asset transfers using a bridge.
3. Conditional Token gated spaces in metaverse to stop spammers in public rooms.
4. Web3 communication system that is privacy preserving and also sensorship resistant.

Challenges I ran into

1. As the project was built in Unity, SDK compatability issues arised which took a lot of time to fix.
2. Had to implement own AES decryption function as no safe libraries were available on solidity.
