What It Is

LiberVault is an open-source, non-custodial, multi-chain browser extension wallet positioned around the idea of “Hold your keys.” It supports Chrome, Brave, and Edge. Users do not need an account, email address, or KYC; they can generate a local 12-word BIP-39 seed phrase and derive ETH, BTC, SOL, DOT, Liberland, and XMR addresses from the same seed.

Core Features and Supported Assets

LiberVault lists support for ETH, BTC, SOL, DOT, LLD, and XMR, and notes that EVM support can cover RPC endpoints such as Polygon, BSC, Arbitrum, and Base. What stands out compared with typical browser wallets is its Monero support: it implements full RingCT via monero-javascript WASM, with the spend key never leaving the extension and the view key used only for scanning. The current roadmap shows that ERC-20 tokens, SPL tokens, Substrate assets, transaction history, fiat pricing, custom RPCs, and other features are still planned for later stages. For now, it is more focused on basic sending, receiving, and balance viewing.

Security and Compliance

Its security design centers on local storage and key isolation: the password is used to derive an AES-256-GCM encryption key through 600K rounds of PBKDF2-SHA256, and the encrypted vault is stored in chrome.storage.local. Private keys are used only in the memory of the MV3 background service worker; the popup and content scripts do not access keys and only receive signatures. LiberVault uses the noble/scure cryptography libraries and implements EIP-6963 to avoid conflicts with wallets such as MetaMask. Note that an independent security audit is listed on the future roadmap; the main text does not show that a third-party audit has been completed, nor does it disclose licenses, insurance, or any cold-wallet custody arrangements.

Pricing, Pros, and Cons

The project is marked as Forever free, GPL v3 open source, with no servers and no telemetry. No platform fees are disclosed. On-chain transfers may still incur network fees, but the page does not provide fee-rate details. Its strengths are that it is free, transparent, requires no KYC, uses one seed phrase across multiple chains, and offers relatively rare Monero support. Its drawbacks are that it is still early-stage and lacks built-in trading, fiat on/off-ramps, token asset support, transaction history, hardware wallet support, and information on a completed audit.

Who It’s For and Access from China

LiberVault is suitable for users who value self-custody, open-source auditability, privacy-coin support, and basic multi-chain sending and receiving. It may also interest developers studying GPL wallet implementations. It is not ideal for beginners looking for one-stop crypto purchases, leveraged contract trading, custodial customer support, or fiat payment channels. The source text does not specify accessibility from China; as a browser extension, installation may depend on access to the Chrome Web Store. Possible alternatives include MetaMask, Rabby, OKX Wallet, Trust Wallet, Phantom, Keplr, and Cake Wallet.
