Once again, Ethereum’s Vitalik Buterin is setting the tone for the future of crypto infrastructure. This time, it is about the design philosophy behind wallets and their role in the browser stack.
The conversation began after a new wave of tools was introduced that allow wallets to live directly inside web pages, eliminating the need for browser extensions, separate apps and passwords.
Though many in the Ethereum ecosystem are celebrating the reduction in friction and smoother user flows, Buterin is pushing back. He cautions that this approach might be too simplistic.
It is clear these tools solve real onboarding pain, and he does not dismiss the convenience angle. Nonetheless, according to the ETH visionary, the long-term direction should move in the opposite way: not toward more invisible integration but rather toward stronger interfaces that users can choose and that work on their behalf.
I get the convenience benefits but I also see risk from going in this direction.
We need more sophisticated software that is chosen by the user and incentive-aligned with the user to stand in between the user and apps and stand up for the user’s interests, not less.
In-app…

That means browsers that are not just passive windows into apps, but active participants — doing security checks, enforcing decentralization standards like IPFS-hosted UIs and stripping out the crypto equivalent of surveillance trackers.
Vitalik’s vision
To Buterin, building wallets into apps just postpones the real problems. Such an approach centralizes too much, gives apps more control than they should have and reduces the chances of users being protected when things break.
Buterin’s perspective is informed by years of advocating for what he calls “minimum viable decentralization” — tools that not only make Web3 more usable but also defend its principles.
This perspective does not aim to slow down innovation. Instead, it aims to redirect it. The goal is not fewer steps; it is better ones — ideally, steps that do not require trusting every site you interact with.
As the Web3 UX wave matures, Buterin’s message is clear: convenience is great but not at the cost of autonomy.
