WATS Wallet: non-custodial Web3 wallet with a Chrome extension, a mobile app and an NFC Metal Card

WATS Wallet is a non-custodial Web3 wallet made by Alltoscan LLC. It comes in three products: a Chrome (Chromium) browser extension, an iOS and Android mobile app, and an optional NFC Metal Card. It supports EVM networks, Solana and TON for sending, receiving, swapping and bridging. You create and hold your own keys and recovery phrase, and WATS never holds a key.

Yes — the Chrome extension and the mobile app are both free to use. On EVM networks every action (swap, transfer or staking) is paid in a single fee token, ATS, instead of the chain's native gas — the same fee model in the Chrome extension and the mobile app, and it covers the live network cost rather than acting as a discount. Solana transactions pay their own native fee in SOL, while fees on TON are paid in ATS too.

WATS Wallet supports 10 EVM networks (Ethereum, BNB Smart Chain, Arbitrum One, Optimism, Base, Polygon, Gnosis, Celo, Mantle and Cronos), Solana and TON, in both the Chrome extension and the mobile app. Native Bitcoin is not supported.

WATS Wallet is non-custodial — you control your own keys across every WATS product, and WATS never holds a key.

On EVM networks ATS is the single fee token across every WATS product — the Chrome extension and the mobile app: swaps, transfers and staking are paid in ATS instead of the chain's native gas. On TON fees are paid in ATS too, while Solana transactions pay that chain's own native fee in SOL.

The WATS NFC Metal Card is a military-grade physical card with an embedded NTAG 216 chip carrying a unique ID. The first time you tap it to your phone in the WATS mobile app, the card pairs with that device — from then on it works only with that paired phone, as a tap-to-authenticate second factor for your WATS Wallet accounts.

WATS Wallet is built and operated by Alltoscan LLC, a company founded in 2019, and was last updated on October 27, 2026.

WATS Wallet is non-custodial, so you hold your own keys — WATS never holds a key. The NFC Metal Card uses an NTAG 216 chip with a unique card ID and pairs with a single device in the WATS mobile app, so it works only with that paired phone for tap-to-authenticate access.

The WATS NFC Metal Card is sold in sets at store.watswallet.com: plastic card sets start at $54.90 and the steel card at $149.90. The store lists the current sets, with cards in 304 stainless steel or plastic.

Losing the card does not put your funds at risk: the NFC Metal Card holds no keys and never stores your crypto, and your recovery phrase can always restore your wallet. If you need help with access in the app, email info@alltoscan.com.

Yes. WATS is one identity across three products: a mobile app for iOS and Android, a Chrome extension for desktop browsers, and the NFC Metal Card — all tied to the same wallet.

The Chrome extension and the mobile app are free to install and use; the NFC Metal Card is an optional paid accessory sold at store.watswallet.com, with plastic card sets from $54.90 and the steel card from $149.90. ATS is the single fee token for actions on EVM networks — swaps, transfers and staking — in the Chrome extension and the mobile app alike, instead of holding each EVM chain's native gas token. Solana transactions pay their own native fee in SOL, while fees on TON are paid in ATS too.

The watswallet.com site is published in 12 languages: English, Turkish, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Korean and Arabic. The app and extension interface languages are listed on each store page.

WATS combines three products under one identity — a Chrome extension, a mobile app and a military-grade NFC Metal Card — all sharing the same single ATS fee token on EVM networks, so you get browser, mobile and physical access from one self-custodial wallet.

WATS Wallet is a non-custodial software wallet in your browser extension and on your phone, so it is a hot wallet in the usual sense: your keys live in the apps, not offline. The optional NFC Metal Card holds no keys and is not cold storage; it adds a tap-to-authenticate step in the mobile app.

No. WATS Wallet is self-custodial software, so you create a wallet and start using the Chrome extension or mobile app without identity verification, and you alone hold the keys.

Yes. WATS has built-in swap and bridge tools, so you can exchange tokens and move assets across major EVM chains, Solana and TON from one screen. On EVM networks, swaps and bridges are paid for in the single ATS fee token — in the extension and the mobile app alike; on TON fees are paid in ATS too, and on Solana you pay that chain's own native fee, SOL.

Yes. Staking is one of the WATS wallet actions, and on EVM networks it is paid for in the single ATS fee token instead of the chain's native gas — in the Chrome extension and the mobile app alike.

Yes. WATS keeps everyday Web3 simple: one identity works across the extension, mobile app and NFC card, and the single ATS fee token means you don't have to buy a different gas coin for every EVM chain — all while you keep full self-custody of your keys.

No. WATS Wallet does not support native Bitcoin. It supports 10 EVM networks (Ethereum, BNB Smart Chain, Arbitrum One, Optimism, Base, Polygon, Gnosis, Celo, Mantle and Cronos), Solana and TON, with send, receive, swap and bridge.
