Majik Key is a next-generation seed phrase account library for creating and managing mnemonic-based identities. It provides a post-quantum ready, high-security bridge between BIP39 mnemonics and the Majikah ecosystem.

Majik Signature is a hybrid post-quantum content signing and verification library for the Majikah ecosystem. Built on top of Majik Key, it provides tamper-proof, forgery-resistant digital signatures for any content format — using a dual-algorithm architecture that combines classical Ed25519 with post-quantum ML-DSA-87 (FIPS-204).

Convert Ed25519 public keys between various encoding formats.

Ruby FFI binding to the Networking and Cryptography (NaCl) library (a.k.a. libsodium)

Ed25519 signature verification for Solana programs

Guardrails for AI agents, with a receipt. Blocks destructive tool calls before they run and signs every decision into a hash-chained record anyone can verify with an open-source tool.
