After using the easy-to-use web3 wallet, you will realize that when the threshold for use is lowered in the future, it must be protocol > chain. A good protocol can retain users and cover multiple chains at the same time. Which chain is used specifically depends on the user. In fact, the sensitivity is not high (when the gas level is the same), so the future is likely to be a fat protocol + multi-chain model, rather than the unification of all chains that everyone is pursuing.
