What's the real endgame here? Total decentralization.

The crypto payment game just shifted. Now there's this thing where you actually hold your own keys—no intermediaries, no custodial headaches—but still swipe anywhere that takes Mastercard or Visa. Yeah, you read that right.

No more choosing between self-custody security and real-world usability. Your wallet, your rules, but the infrastructure works exactly like any traditional card network. Tap at coffee shops, online checkouts, gas stations—wherever plastic works, this works.

That's the promise of these new self-custodial payment cards. Full control meets mainstream adoption. Pretty wild when you think about it.
