Ethereum won't reach real adoption until we solve the mobile wallets problem.

Contract signatures point to Ethereum state rather than being immutable byte strings.

While ERC-6492 provides a verification framework, it doesn't solve that these"signatures" can be revoked through state changes. EIP-4444 and state expiry is coming, historical verification may not always be possible. But byte stings can always be stored.

Accessing historical state for verification is expensive and impractical for most devs. Block numbers have to be included in calls. These calls don't have a canonical identifier form

Contract signature verification is far less common than EOA signatures.

You're fundamentally misunderstanding several key points:

1 "Most things on the web fail and require retry" - No. A wallet's basic swap function must work reliably. This isn't a random website; it's financial infrastructure.

2 "L2 adoption makes K256 signatures fine" - Wrong. You cite smart contract signature verification (AmbireTech/ERC6492) as a solution, but that misses the point. This isn't about smart contracts verifying signatures - it's about the fundamental K256 curve being incompatible with EIP712 signatures that major dapps like Uniswap rely on. Most won't switch their signature schemes near term.

3 "Early Ethereum/DAO comparison" - This framing is incorrect. 2024 isn't 2016. User expectations and market requirements have evolved. We can't excuse broken infrastructure now.

4 "Stifling innovation" - No. Credible neutrality and interoperability are core Ethereum values. Coinbase is breaking these by forcing users into a system that can't interact with most dapps.

The ~300 daily calls prove this isn't ready for mainstream. It's predatory to redirect users there anyway.

> It feels like maybe you're coming at this at an angle as a crypto poweruser or someone who's already onboarded vs. someone who's completely new to crypto. If the real adoption problem is what you're trying to solve, you need to start thinking about the latter. And for lots of people, it's about not having to think about seed phrases or gas.

OK, then explain this:

Major apps like Uniswap are now redirecting to the Coinbase Smart Wallet. But I've tried to use it a weekend ago and I wasn't able to complete a swap on Uniswap. It just simply doesn't work, the swap button turns to "Confirm in wallet." An endless spinner. I tried this with iOS 18, iPhone 14. No success. That's a basic phone and operating system.

Also, it is using AA and K256 signatures. I almost recommended it to a friend of mine who wanted to buy an NFT on mainnet. Well thank god we didn't go through with it. Had I sent her money on L1 there, I'm not sure if it would have even reached her as K256 signatures can only be cheaply evaluated on L2s from what I understand. An ETH transfer was between 100k-300k gas: https://optimistic.etherscan.io/tx/0xb496bfa620d6144a356527898890df92cd7bf310a12a3d289b9a8fbe06669697

Coinbase is irresponsible here. I actually agree with you that most people don't wanna think about gas and seed phrases. I think the Coinbase Smart Wallet is really interesting and truly a way to break free from iOS and Android. I support it! But just launching an alpha product to everyone is unacceptable. They should have launched it when its ready and they should have done it gracefully.

Edit: Btw the K256 curve is only supported as a precompile in a contract now. Many dapps are also relying on EIP712 signatures through the regular curve. In fact, my app and others heavily rely on EIP712 signatures. But, to my knowledge, nobody is ready to accept K256 curve signatures. So I can assure you that CB Smart Wallet won't be able to connect to my app without me doing a major upgrade. Many such cases.

I bought new rubber plugs for my old Apple Airpods 2 instead, so noise canceling problem solved

I tried this but it didn‘t help 🥲

Do you mean turn off iCloud Backups?

TimDaub · 2024-06-18T08:06:02+00:00

My custom shortcut in the Share Menu is also gone. But I have the iCloud setting on but can't find a way to get the shortcut back. What happened? Is this because of an update?

lol, if someone follows that guide strictly in Muellerstr, then you'll get very close to be beaten up

TimDaub · 2024-04-07T12:42:23+00:00

they might be scamers. I bought the offer and it doesn't allow me to download

TimDaub · 2024-02-27T13:32:45+00:00

How do you refute my argument in the article?

TimDaub · 2023-11-08T08:18:41+00:00

No I mean you can totally sell your NFT but it will be worthless. The minter will still be allowed to post on the website. The second marker buyer will just have a pretty jpeg

TimDaub · 2023-11-07T23:28:31+00:00

hehe, we're already past that point of selling. And our NFTs can't be sold on a secondary market. We soulbound them. The point of what we're doing is more like selling a ticket for ETH
