§ docs

where the docs live.

OC Vault docs are split intentionally: this site hosts the product landing, the unified docs site hosts the SDK and integration reference, and the protocol repository hosts the normative spec. Three surfaces, one family.

quick orientation

who is oc vault for?
Anyone with secrets — passwords, seed phrases, TOTP seeds, API keys, secure notes, small files. Bitcoiners storing their seed phrase is the wedge audience, but the product is broad.
what's the trust model?
OC holds ciphertext only. The cryptographic contract — "only the wallet can decrypt" — is the product contract. No master password, no recovery backdoor, no KDF policy promises.
is this the same as a hardware wallet?
Complementary. Your hardware wallet protects your sats; OC Vault uses that same wallet's BIP-322 signature to gate access to your encrypted secrets. One wallet, both jobs.
can I self-host?
Yes. The protocol is open and the SDK is MIT-licensed. Run your own relay, or skip the cloud entirely and live on local + manual export. vault.ochk.io is a paid convenience, not a requirement.
