BIP-85 PR adds Codex32 as application 93
Bitcoin BIPs PR #1958, submitted by BenWestgate in April 2026, proposes adding Codex32 as application 93 in BIP-85. The draft also adds a derivation path, references BIP-0093, bumps the BIP-85 version to 1.4.0, and points to reference implementations in benwestgate/bip85 and benwestgate/bipsea.
Mechanically, this would put Codex32’s checksummed base32 encoding and Shamir-style secret sharing inside the BIP-85 derivation model, using BIP-32 master keys to deterministically derive share material for backups with error correction.
Caveat: the PR is still labeled “Pending acceptance” and “PR Author action required.” The open design question is whether BIP-85 should remain focused on entropy derivation from keychains, or also absorb Codex32/BIP-93 semantics despite stated concerns around BIP-93 maturity, test coverage, interoperability, and backward compatibility.
