If compared to Ethereum which already has Layer2, it means that Solana also cannot be completely equated with Ethereum.
Ethereum is already expensive and has very expensive fees too, that's why the Ethereum community created Layer2 to reduce transaction fees.
For the Solana coin, I'm not sure the community created Layer2 because the Solana coin transaction fee is still cheap and affordable.
It is also possible that if one day the Solana coin transaction fee reaches 3 dollars, then I'm sure the community will also create Layer2 for the Solana coin.
