For the Coldcard, we expect a PSBT to be 'uploaded' over USB (can also be provided on MicroSD card) and we work in-place with it, scanning over it a few different times. If the user approves the transaction, we produce a signed PSBT or final transaction and that gets downloaded. We support 256k byte PSBT files with hundreds of inputs/outputs (IIRC, and exact limits still TBD) and are operating in a system with only 25k free RAM after startup. > Furthermore, I forget to mention in my last mail, that registering (or defining) > a mime-type for PSBT would probably a great usability feature. > (Send PSBT by email/messanger and with dbl-click to open feature, etc.) +1 for mimetype, especially since it's a binary format. --- Peter D.
