Yes. There’s no charge to use it, no premium tier and nothing behind a paywall, and wwwallet adds no fee to anything you send or swap. The only unavoidable cost is the network’s own transaction (gas) fee, which goes to the network rather than to wwwallet. Swap quotes come from the 0x exchange aggregator (or LI.FI, on networks 0x doesn’t cover), which can include its own fee on some trades — any such fee is listed on the review screen before you confirm.

No. wwwallet shows no ads, runs no analytics or tracking scripts, and doesn’t build a profile of you. There’s no account, so there’s nothing to attach one to.

No. There’s no sign-up, email address, phone number or identity check — you create a wallet on your device and start using it.

It doesn’t make money from its users — no fees, no ads, no data sales. Running costs are kept small by design: the app itself runs in your browser, and the backend only relays public blockchain and price data.

There’s no account, so there’s nothing for wwwallet — or anyone else — to freeze. Your keys never leave your device, and transactions are signed there before they’re sent to the network. Your funds live on Ethereum, not in wwwallet: you can view any account’s private key or recovery phrase from its menu and import it into any other Ethereum wallet app whenever you like.

Not by itself. Your recovery phrase unlocks your encrypted vault, but the vault itself lives only on your device. If you lose or wipe that device without ever taking a backup, there’s nothing left for the phrase to unlock. Always pair your recovery phrase with a Google Drive or file backup — see the next question.

From Settings, back up your encrypted vault to your own Google Drive or as a file you download and keep yourself. A Drive backup goes in a private app folder, and wwwallet can’t see anything else in your Drive. Back up when you first set up, and again whenever you add accounts.

Yes, but it doesn’t sync automatically — each device holds its own local vault. To use wwwallet on a new device, restore it there from a Drive or file backup, then unlock with your recovery phrase.

Your funds are unrecoverable. That’s by design: wwwallet has no account system and keeps no copy of your vault anywhere, so nobody — including us — can restore it for you. It’s the trade-off for keys nobody but you can access.

No. A passkey is tied to the device it was created on. After restoring a backup on a new device, unlock with your recovery phrase and you can set up a fresh passkey there.

No — it’s source-available. The full source is public on GitHub so anyone can read, review, and audit it, but it isn’t open source: the code is licensed under the PolyForm Strict License 1.0.0.

You can read and audit all of it, and run an unmodified copy for noncommercial purposes such as personal study, research, and testing. You can’t distribute it, modify it or build derivative works (including forks), or use it commercially. If you need something the license doesn’t allow, contact the copyright holder for a separate license.

wwwallet is non-custodial software provided “as is”, without warranty of any kind. You alone control your keys and funds — nobody, including us, can recover a lost recovery phrase or backup, reverse a transaction, or compensate you for losses. Only use funds you can afford to lose, double-check addresses and networks before you send, and nothing here is financial, investment, legal, or tax advice.

Ethereum mainnet, plus Arbitrum, Base, Optimism, Polygon, Robinhood Chain, World Chain, Ink, Linea, Gnosis, Celo, ZKsync Era, Ronin, Unichain, and Scroll — all from the same set of accounts.

Open an account, choose “View QR code” to see its address, and send funds to that address from an exchange or another wallet. Make sure you send on the right network (such as Ethereum, Base, or Arbitrum) — the same address works on every supported network, but funds sent on one network only appear on that network. You’ll also want a little of the network’s native coin (such as ETH) to pay transaction fees.

Send: transfer ETH or any token to an address you paste, scan from a QR code, or pick from your own accounts, and review the details before you confirm. Swap: exchange one token for another on the same network from the Swap tab, with a quote and fee estimate shown up front. Receive: show your address as a QR code. You can also see your balances with USD values and your transaction history across all supported networks.

Nothing that identifies you. There’s no account, login, or database. Balance and price data is fetched through wwwallet’s own backend rather than your browser calling third-party providers directly, and that backend never sees your keys, passwords, or recovery phrase.
