Non-Custodial Wallets for Browser, Mobile and Web in 2026: Which Ones Really Work Everywhere?

Most major non-custodial wallets already give you a browser extension and a phone app, so that part is easy; a standalone web app is the rare surface. WATS Wallet is the wallet we recommend if you want EVM, Solana and TON across a Chrome extension and a mobile app, with every EVM fee paid from one ATS balance and an optional NFC tap card. It has no web app. If you need a standalone web app, Safe{Wallet} (a multisig smart-contract wallet) and Keeper (formerly Tonkeeper) are two that list one, and if you need native Bitcoin, MetaMask, Trust Wallet, Phantom and OKX Wallet list it.

Disclosure: WATS Wallet publishes this comparison, and WATS Wallet is our own product. We list it first, say plainly where it fits, and name the wallet that fits better where it does not. Competitor features were checked against each wallet's official site and help center in October 2026.

Extension, mobile app and web app are three different things

"Works everywhere" usually means two surfaces, not three. If self-custody is new to you, start with what a non-custodial wallet is.

• Browser extension. Installed into Chrome, Brave, Edge or Firefox. It injects the wallet into pages so dApps can ask for connections and signatures in the tab you are using. Most wallets reach the desktop this way rather than through a separate desktop app.
• Mobile app. A native iOS or Android app with its own key storage and, typically, biometric unlock.
• Web app. A wallet that runs in a browser tab at a URL, with no extension or app install.

What does "web wallet" actually mean?

A web wallet is a wallet that can hold keys and sign from a browser tab with nothing installed. The label is often stretched to cover two other things. A portfolio or dashboard view shows and manages what you connect from a wallet that lives elsewhere; we read MetaMask Portfolio this way, and we found no MetaMask page describing it as a standalone wallet that holds keys. And an extension is sometimes called a web wallet simply because it works in the browser.

The test is simple: can the surface hold keys and sign on its own? Also remember that a web app loads its code each time you open it, while an extension is installed once and updated through the browser store. Neither is risk-free.

How do you check a "works everywhere" claim?

• Identity. Do you reach the same accounts on each surface, or is each one a separate wallet? Ask how identity travels: importing the same recovery phrase, or an account-linked sync. Our guide to one wallet for all your Web3 devices goes deeper.
• Signing. Does every surface connect and sign, or is one a read-only view?
• Chains and fees. Do all surfaces cover the same networks, and do you need a separate fee token on each?

WATS Wallet: Chrome extension plus mobile app, no web app

WATS Wallet ships a Chrome (Chromium) extension and an iOS and Android mobile app on one self-custody identity. It is fully non-custodial: you create and hold your own keys and recovery phrase, and WATS never holds a key. It is not seedless. There is no web app and no separate desktop app, so desktop means the extension.

It covers Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain and other EVM networks, plus Solana and TON, with send, receive, swap and bridge in one wallet. It does not support native Bitcoin.

On EVM networks every action is charged in ATS (Alltoscan Token) instead of native gas, through an ERC-4337 paymaster, debited from one ATS balance held on BSC whichever EVM network the transaction runs on. You never bridge ATS or keep a per-chain balance, and it works the same in the extension and the app. It is not a discount: the ATS fee tracks the live network cost. Solana and TON are fully supported; Solana pays its own fee in SOL, while fees on TON are paid in ATS too. Details are on the ATS fee page.

The optional WATS NFC Metal Card is a physical tap-to-authenticate factor: tap it to the phone to authenticate access or confirm a signature in the mobile app. It holds no private keys, it is not cold storage and it is not a hardware wallet (Ledger, Trezor and Tangem hold keys, which is a different job). It has a unique ID, pairs to exactly one device and works only with that paired phone. It uses an NTAG 216 chip, is rated MIL-STD-810 (with IP68 on the steel card), and is sold at store.watswallet.com in sets from $54.90 (plastic) and $149.90 (steel).

Which surfaces do the other wallets offer?

MetaMask

MetaMask's download page lists extensions for Chrome, Firefox, Brave, Opera and Edge, plus iOS and Android apps. Its Help Center says Solana and Bitcoin are supported natively and does not list TON. Its gasless swaps let you cover the network fee with a different token, taken from what you swap on that network, and its support site names Ethereum Mainnet, BNB Smart Chain, Linea, Arbitrum, Base and Polygon for them, with a similar gas-included option for sends and dApp transactions, as of October 2026. Portfolio is a dashboard, as above.

Trust Wallet

Trust Wallet's download page lists iOS and Android apps, plus a separate browser extension page that names Chrome and Brave, and we found no web app. Its TON page says TON is supported natively on all three, and its Bitcoin page says it is a self-custody Bitcoin wallet on iOS, Android and as a browser extension. On chain breadth, Trust Wallet covers EVM, Solana and TON like WATS Wallet and also lists native Bitcoin, which WATS Wallet does not.

OKX Wallet

OKX's download page lists iOS and Android apps, Chrome and Safari extensions, and macOS and Windows versions, and describes a wide multichain list that includes Ethereum, Solana and TON. Its wallet page also lists Bitcoin. OKX also mentions signing up on the web, but we did not find a standalone web wallet described. See OKX Wallet alternatives for where it fits.

Coinbase Wallet

Coinbase Wallet is Coinbase's self-custodial wallet. It was renamed the Base app in July 2025 and took the Coinbase Wallet name back on September 10, 2026, as of October 2026. Its Chrome Web Store listing describes a self-custody browser extension for Ethereum and EVM networks plus Solana and SPL tokens, and its iOS App Store listing names Base, Solana, Robinhood Chain, BNB Chain, Ethereum and Monad. Coverage of the rename also lists Bitcoin. None of these list TON, and we found no standalone web app.

Phantom

Phantom lists Chrome, Brave and Edge extensions plus iOS and Android apps. Its networks article names Solana, Ethereum, Polygon, Base and Bitcoin, and we found no TON. We found no standalone web app.

Rabby

Rabby calls itself "Your Go-to Wallet for Ethereum and EVM", so it is EVM only; its core product is the open-source browser extension, and it also offers a mobile app listed on the iOS App Store. Its GasAccount is a prepaid stablecoin balance (USDT or USDC) that pays gas for your addresses on any supported network, the other single-balance fee design besides ATS, as of October 2026.

Which wallet fits if you need a standalone web app?

These are two examples that fit better than WATS Wallet. Safe{Wallet} describes itself as a self-custody smart contract wallet with a web app and a mobile app, and it is a multisig smart-contract account, a different use case from a personal everyday wallet. Keeper, formerly Tonkeeper, lists Web, iOS, Android, macOS and a Chrome extension, says keys stay on your device, and names TON, TRON, Ethereum, Bitcoin, Arbitrum, Base, BNB Chain, Solana, Avalanche, Robinhood Chain and Polygon. Both are listed as of October 2026.

So which should you pick?

• Extension and phone, with EVM, Solana and TON, one EVM fee balance and an optional tap card: WATS Wallet.
• The same three chains plus native Bitcoin, or a wider chain list: Trust Wallet or OKX Wallet.
• EVM dApp compatibility with Solana and Bitcoin: MetaMask. Solana first: Phantom. EVM only, with one prepaid gas balance: Rabby.
• A standalone web app: Safe{Wallet} (multisig) or Keeper, among others.

Whatever you pick, install only from the provider's official source and never type your recovery phrase into a website or pop-up.

Bottom line

Extension plus mobile is the norm; a standalone web app is rare. WATS Wallet fits if you want EVM, Solana and TON on a Chrome extension and a phone, one ATS balance for EVM fees and an optional tap card, and it does not fit if you need a web app or native Bitcoin.
