Knowingly, using common sense, we’ve concluded that a Bitcoin “piggy bank” can’t live on-chain with a self-custody setup. At ~600 sat/vB, self-custody fees eliminate about 99% of use cases, and the remaining 1% is already covered by plenty of existing wallets. This is a long-term project, and we’re sure fees won’t remain as low as they are today and self-custody will become unaffordable for many. It’s not a question of if, but when.
