// SAFETY MODEL

Offline is a boundary, not a promise.

BitFloppy is a testnet/signet proof of concept. Its primary safety boundary is the separation between a networked wallet application and the private signing material on the board.

DEFAULT STATE

Locked

  • Public wallet files are available.
  • Private material stays unavailable.
  • Use this state for normal operation.

SIGNING STATE

Unlocked

  • Private material is exposed to the device workflow.
  • Required for transaction signing.
  • Keep this period short and controlled.

Practical safety checklist

✓

Use testnet or signet only. Do not use this proof of concept with real funds.

✓

Verify transaction details in your wallet application before creating a PSBT.

✓

Safely eject the USB drive before restarting the board.

✓

Restart the board after signing to return to the locked state.
