You trust a company with your keys. You call it self-custody. It is not.
Coldcard users trusted a company. They got a 72-bit entropy bug and a $38 million bill.
Ledger users trusted a company. They got their seed database leaked and a class action.
Every black-box wallet is a trust company wearing a Bitcoin t-shirt.
The only real self-custody is verifiable self-custody.
Blockstream Jade is open source. You can build it yourself if you want. You can read the firmware. You can check the math.
That is not trust. That is verification. That is actually yours.
