My focus as an engineer is to improve self custody UX so that users don't feel the difference. I cannot blame users for it. LN failed to achieve this for several reasons:
1. Channel management
2. Intiial liquidity
If organizations like HRF keep supporting custodial solutions things can take time. However, I am hopeful Ark will provide better alternatives for application developers and users.

2025-06-06 20:11:03

- reply

Users don't need to give up self custody for privacy.
Keep misleading users about the "freedom tech" in which users don't own keys and need permission from mints to transact.

2025-06-06 20:06:10

HRF wants people to vibe code wallets that are used for payments. What could go wrong?
I am assuming most of these wallets will use ecash because HRF doesn't like freedom for users.
