None of todays crypto wallets will ever reach PMF.

First, by PMF I mean ~100 million users in 5 years. By crypto wallets, I mean literally every wallet that is live now, including both incumbents like Metamask and fresh contenders like Rainbow, Family, or Uniswap Wallet.

My retort is always: we can't abstract over credit cards today. Chains are much more heterogeneous than those - and it's worse for bridges. I doubt we can abstract over those - it just wouldn't be safe or wise.

Or you need something like crypto FDIC insurance.

Would something like Gnosis Pay (https://gnosispay.com/) be enough abstraction over credit cards? Or what else do you find missing? Multi-chain support?

Perpetual soldier of fortune, occasional internet slacker.

Cooking 0xFable — the fully on-chain trading card game for nerds

You're way in the future: amex is not accepted in a lot of places & two of the three cards (Visa & Mastercard) I carry get routinely rejected in places accross the world (not the same). It happened once they wouldn't take any of the three 😅

My point was that the heterogeneity problem is not fully solved outside crypto, so I'm not sure why people insist it *must* be solved in crypto.

In crypto, the security assumptions have a lot more variation than Visa-Amex-Mastercard too.

There are solutions, but you certainly will want to know where your assets are.

Gotcha, so your point was to accept crypto directly at the POS, to bypass credit card networks altogether, right?

That was Bitcoin's intent as described in the abstract of its whitepaper. I find it sad that 15 years later and no meaningful progress has been made.
