Ethereum

What features would a maximally "Ethereum-aligned" wallet have?

Censorship resistance requires privacy.

Some ideas:
- Open-source (obviously)
- Doesn't leak (IP, pubkey)-pairs to a centralized service
- Built-in light client
- Account abstraction (?) with social recovery
- A bunch of EIPs for JS integration
- Transparent support for L2 force-inclusion transactions
- ???

Supporting testnets and having a way to connect reliably to a dapp via qr code would already be beating ⅔ of wallets on the market I've used at least

Testnets are a developer-only feature; the subset I'm looking for is "things end-user wallets should have if Ethereum is maximally successful and adopted, and all of its values are preserved".
QR connectivity is good! (But only if it doesn't involve privacy leaks to centralized entities; *cough* WalletConnect *cough*)

testnets could be lumped in with supporting BYO chain info, providing your own RPCs etc I guess. I don't know if people value not having the chains they're allowed to use prescribed to them in the app but could be a rephrasing of the same thing :)
