Overview
Eternl is a non-custodial Cardano light wallet distributed as a browser extension for Chrome, Edge, Brave, and Opera. Developed by Tastenkunst GmbH and formerly known as CCVault, Eternl targets users who want a feature-dense wallet for managing ADA, native tokens, NFTs, and DApp interactions on Cardano1. Encrypted private keys are stored locally on the user's device rather than on company servers, keeping custody with the user2.
The extension serves as a primary interface for the Cardano DApp ecosystem, exposing a CIP-30 connector that lets web applications request signatures, query balances, and submit transactions. Eternl sits alongside other browser wallets such as Lace, Yoroi, and Typhon, and is one of the longer-running options in the category.
Key Features
- Multi-account management. A single seed phrase can host multiple independent accounts in the same extension, letting users separate funds, identities, or use cases without juggling installations1.
- Multi-signature support. Eternl supports creating and participating in native multi-sig wallets directly in the interface, useful for teams, treasuries, and DAOs that require multiple approvals1.
- Hardware wallet integration. Ledger, Trezor, and Keystone devices can be paired with Eternl so signing happens on the hardware device while the extension handles balances and DApp connectivity1.
- DApp connector and browser. A CIP-30 connector and in-wallet DApp browser route users into Cardano applications without leaving the extension, covering DEXs, lending markets, and NFT venues.
- Liquid staking. Built-in delegation lets users browse Cardano stake pools and delegate ADA per account, with rewards accruing while funds remain spendable3.
What to Expect
The marketing site at eternl.io is intentionally minimal and routes users into a single-page app where most of the wallet experience lives. First-time setup walks through seed generation, password creation, and optional hardware wallet pairing, with separate flows for restoring an existing wallet. Account switching, address management, and delegation are surfaced inside the extension popup and the full-page wallet view.
Day-to-day use leans heavily on the DApp connector. Connecting to a Cardano application produces a permission prompt, and subsequent transactions show a structured signing screen with the requested outputs and metadata before the user confirms. Power users tend to favor Eternl for the granular controls, multi-account layout, and willingness to expose lower-level transaction details that other wallets hide.
The closed-source codebase is the most consistent caveat. Eternl does not publish a public GitHub repository, and no third-party audit has been identified, so trust rests on Tastenkunst GmbH's track record and the wallet's long-running deployment rather than independent code review. Users seeking an open-source alternative can compare Eternl against Lace or Yoroi within the same category.
