## What is Coconut Vault Lite?

Coconut Vault Lite — Stateless Offline Bitcoin Signer for Self-Custody

Coconut Vault Lite is designed for users who primarily need offline Bitcoin transaction signing without permanently storing seeds on the device.

Unlike Coconut Vault, "Coconut Vault Lite" does not support persistent seed storage or inheritance wallet functionality. It is intentionally designed to remain a focused Bitcoin signer rather than provide the advanced vault features available in the full version of Coconut Vault.

Coconut Vault Lite keeps your private keys secure in a fully air-gapped environment.
Sign PSBTs (Partially Signed Bitcoin Transactions) without any internet connection.

Designed for those who take Bitcoin security seriously, Coconut Vault Lite uses hardware-backed security (HSM / Secure Enclave) to protect sensitive key material.

Key Features
• QR-based PSBT signing in a fully offline environment
• Supports standard single-sig and multisig transaction signing
• No persistent seed or wallet storage — wallet data is cleared when the session ends
• Seeds and passphrases are encrypted in memory, with encryption keys protected by the device’s hardware-backed security and accessible only after device authentication
• Compatible with Coconut, Sparrow, BlueWallet, and Nunchuk watch-only wallets
• Auto lock and memory zeroization when a network connection is detected

If you want to securely store your seed on an offline device for long-term use, or if you need inheritance functionality, choose the full version of Coconut Vault (not Coconut Vault Lite).
