Really? Will pick one up and play with it. I am shocked this isn’t standard on all hardware wallets. I wrote Trezor and they didn’t reply. I wrote cold card and they said “we are working on the idea.”
Discussion
I skimmed the original post. They offer a login countdown on Coldcards to achieve the same goal: preventing transaction signing for up to 28 days, without technically time-locking UTXOs at a block height.
This assumes seed phrases are stored separately. An attacker could still use the seed on another signer to move the Bitcoin.
Yah you don’t want to technically lock anything. You simply want to restrict the ability to send. Using block height is my idea for tracking time in a way that can’t be hacked.
By technically I meant the configuration of the wallet itself not allowing for UTXOs to be moved unless certain conditions are met. You can restrict spending without doing this using login countdown features.
