Overview
Seedelf Wallet is a Chrome extension wallet that lets you hold, send and stake ADA in the open, and keep a private balance whose owner the chain doesn't show, though moving money in or out links your public account1. It suits people who want one everyday wallet without each payment they receive pointing back to them on the chain. Both sides open with the same recovery phrase (the list of words that backs up a wallet), so there is no second wallet to manage1.
Seedelf Wallet runs on Cardano and is made by Logical Mechanism LLC1. Its private side uses Seedelf, a stealth wallet contract: a program on the chain that holds money without saying who owns it. Each payment to a Seedelf reaches its owner under a fresh copy of their key, and spending is proven with a zero-knowledge proof, a way to show you own the money without revealing which money is yours1. The code is open source under the MIT license2. Cardano's developer documentation lists Seedelf among the experimental zero-knowledge applications built on the network and describes it as a research wallet3.
Key Features
- Private payments by name. You share your Seedelf's name, and a payer pastes it so the wallet finds it. Logical Mechanism says the payment can't be linked to the Seedelf it pays, and that payments to the same Seedelf can't be linked to each other1.
- A public account for everyday use. The public account sends, receives, stakes ADA with a pool and delegates voting power to a DRep, a representative who votes on Cardano governance decisions4.
- DApps without your public account. A private session funds a one-time account from the private balance, so a site such as Minswap sees only that account, and what comes back returns to the private balance1.
- Optional mixing on the way back. Spare ADA from a private session can pass through Lovejoin, a mixer that pools equal 10 ADA amounts from many users so returns are harder to trace, and a Settings switch turns it off5.
- Warnings before you sign. Seedelf Wallet warns you before a payment ties your accounts together, and it decodes each transaction on your device so you can read it first1.
What to Expect
After adding it from the Chrome Web Store, you create a wallet, or restore one from a 12, 15 or 24-word recovery phrase, and lock it with a password4. A phrase from Lace or Eternl opens that wallet's accounts, so switching does not mean moving funds4. The wallet runs on Cardano's main network with real ADA. A switch on the welcome screen or in Settings moves it to preprod, Cardano's test network, where test ADA has no value4. Screens come in English, Spanish and Japanese1.
Day to day, the home screen has two sides, Public and Private. Money in the public account can stay staked and earn rewards. Money in the private balance earns none, by design, because staking it under one key per user would link that user's Seedelfs together5. The wallet's privacy guide spells out what Seedelf hides and what stays visible on the chain6.
Sites can't see the wallet until you turn on connecting in Settings1. After that, any site can connect over CIP-30, the standard way Cardano websites talk to wallets, either to a private session or to the public account1.
A separate terminal tool, seedelf-cli, runs Seedelf on Linux, macOS and Windows and keeps its own key apart from the wallet's recovery phrase1. Support runs through GitHub issues and the project's Discord. A bug bounty pays in ADA for reported flaws that could lead to a loss of funds7.
