How it works
PSF is transformed into OSF using shifts d(i) = len(P[j]) + i, based on the Passphrase (P). OSF looks like a normal seed but leads to an empty wallet.
Advantages
- Works completely offline
- No software needed — just paper
- Plausible deniability — OSF looks like real seed
- Protection against physical access
Risks
- Forgot Passphrase = lost access
- Calculation errors
- Not standardized
Wallet support
- Any wallet (method is external)
Try it yourself
