After researching countless "seemingly useful" features, I have come to realize that simplicity and reliability are the foundation of long-term products. The anxiety that lingered in my heart finally dissipated, and I began to understand why @0xpeterpan_ had to be non-custodial as soon as he came up, "otherwise I wouldn't be able to sleep at night." I personally think UX has passed its hardest time. The rest is to make fewer mistakes, apologize more, and live a long life, so that users can have more.
