Seed16: Roll Your Own Keys
An offline, open-source tool that turns rolls of a physical 16-sided die into a 12- or 24-word BIP-39 recovery phrase.
Field notes
The tool records each physical d16 result as a hexadecimal digit, avoiding the base-conversion problem associated with six-sided dice. Its stated targets are 32 rolls for a 12-word phrase and 64 rolls for a 24-word phrase, followed by automatic checksum calculation. The page also explains how to supply the phrase through a wallet’s Restore or Import flow rather than its new-wallet flow. A Windows release and build-from-source path are linked, while the extract does not verify the software itself.
