Overview
Eternl is a free Cardano wallet that runs as a browser add-on for Chrome, Edge, Brave, and Opera. Everything you need to use Cardano (ADA storage, native tokens, NFTs, staking, swaps, and signing into apps) is packed into one extension. Originally launched as CCVault, it's built by Tastenkunst GmbH and is one of the longer-running browser wallets in the Cardano ecosystem1.
You hold the recovery phrase, which means only you can move your coins. The keys are encrypted and stored on your computer, not on the company's servers2.
Key Features
- Several separate accounts under one wallet. One recovery phrase can host multiple independent accounts inside the same extension, useful for keeping savings, spending, and DeFi activity apart without installing different wallets1.
- Shared wallets that need multiple sign-offs. Set up a wallet that requires more than one person to approve a transaction. That's useful for couples, business partners, DAOs, or any group treasury1.
- Pair with a hardware wallet. Connect a Ledger, Trezor, or Keystone device so the recovery phrase stays offline while you use Eternl for everyday actions1.
- A built-in browser for Cardano apps. Open Cardano DEXs, lending platforms, and NFT marketplaces inside the wallet itself, with the same approval flow used for normal payments.
- Stake ADA per account. Each account in Eternl can delegate to a different stake pool, giving you fine control over your staking strategy. Your ADA stays liquid the whole time3.
What to Expect
Setting up Eternl takes a few minutes. You install the browser add-on, create a wallet, write down a recovery phrase on paper, and set a spending password. From there you can either use the small popup interface or open the wallet in a full-page view for more room.
Eternl is one of the most feature-rich Cardano wallets, which means newcomers may find it a bit busy at first. Approving a transaction inside a Cardano app shows you exactly what's being signed, including the amounts and any extra notes attached, so you can confirm everything before clicking.
There's no public GitHub repository, and no independent security audit has been published, so trust rests on Tastenkunst's long operating history rather than third-party review. Users who prefer open-source code may want to compare Eternl with Lace or Yoroi in the same browser wallet category.
