There are still so many developers that don't understand how important multichain is, just because your project is on solana network doesn't mean everyone will want to use your project or play the game, there are few projects that I decide to let go because of their smart contract, I am a ERC 20 projects fan not solana or matic, make sure your project is available of every chains out there for easier adoption...
In the near future only multichain can bring all good projects together either in the payment field, layer 1 or gaming field, this is the definition of a fulfilled crypto future.
