Questions about each
CoolWallet
How much does a CoolWallet cost?+
CoolWallet is a hardware wallet, so the cost is the device price of $39 to $149. There is no account or monthly charge attached to holding coins on it, and the keys stay with you. Expect to pay for the hardware once rather than per year.
Does CoolWallet hold my coins for me?+
No, custody is self custody, and self-custody also appears in the listed features under self custody. You hold the wallet and the seed phrase, so losing either one means losing access. That is the trade for keeping control.
GridPlus Lattice1
How much does the GridPlus Lattice1 cost?+
The device is priced at $397 as a one-off purchase. That is a far bigger outlay than the €69.28 typical of hardware wallets, so the budget matters as much as the security design. There is no ongoing account fee attached to the hardware itself.
Who holds the coins on the Lattice1?+
Keys stay with the holder, and the device works in self custody. Nothing sits with a provider on your behalf, so there is no third party to ask if a seed is lost. You also cannot lean on a provider's support team to restore access, because recovery starts with your own backup.
