Hello bitcoin-dev, I’m Ben Westgate, a contributor interested in deterministic wallet backups and seed management. Per BIP-0002, I propose listing *BIP-0093 (codex32)* as an application of *BIP-0085 (Deterministic Entropy from BIP32 Keychains) *, similar to the existing BIP39 application. This allows wallets to derive codex32 backups from BIP-0032 master keys. *Summary* - Application number: 93' - Derivation path: m/83696968'/93'/{hrp}'/{threshold}'/{n}'/{byte_length}'/{id0}'/{id1}'/{id2}'/{id3}'/{index}' Codex32, defined in BIP-93, is a human-readable encoding with checksumming and share indexing designed for SSS backups of BIP-0032 seeds. This PR proposes a deterministic way to generate codex32 strings using BIP-85. *Rationale* - Mirrors the existing BIP-85 application for BIP-39. - Codex32 offers error correction, hand verification, identifiers, and secret sharing features compared to BIP-39. - Adds a standardized way for wallets to generate codex32 backups from BIP-85-derived entropy - Test vectors and reference implementation are linked to in the PR. *Risks and alternatives* - Wallet adoption of codex32 is still limited, though a draft PR #32652 for importing codex32 strings to Bitcoin Core has support. - Codex32 implementers could use the BIP-85 dice application, but defining a direct application improves interoperability.
