Stellar makes offline signing feel native.
SEP-7 gives a Stellar transaction a clean QR-shaped request format. Better Wallet Pi uses that to keep signing offline without hiding the handoff from the person approving it.
Notes from the air gap.
Short, practical essays on why Better Wallet Pi centers Stellar, how SEP-7 fits an offline workflow, and where the prototype still needs scrutiny.

Field notes for Stellar-first offline signing.
Product notes, security decisions, and build logs for the wallet. Stellar leads the publication because SEP-7 is the clearest demonstration of the air-gapped flow.
An air gap is a product decision, not a decoration.
The useful part of being offline is not the theatre. It is the boring, repeatable fact that every transaction crosses a visible human checkpoint.
The Raspberry Pi is a good prototype, not a magic vault.
Commodity hardware makes the design approachable and auditable. It also means the security story has to be plain about what has not been hardened yet.
