WATS Wallet in a nutshell
WATS Wallet is a non-custodial, multi-product Web3 wallet that brings four ways to use crypto under one identity — a Chrome extension, a mobile app, a browser-based Hot Wallet and a physical NFC Metal Card.
One wallet across four surfaces — a browser extension, an iOS and Android app, a web Hot Wallet and an NFC Metal Card — all sharing the same self-custodial keys.
Single-token fees: the Hot Wallet pays for every action — swaps, transfers and staking — in one ATS token, so you never juggle each chain's native gas.
Multi-chain by default: send, receive, swap and bridge across major EVM (Ethereum Virtual Machine) chains plus Solana and TON from one interface.
You hold the keys: WATS is non-custodial, and the Hot Wallet uses a dual-custody model where you and WATS each hold a separate key.
Tap to authenticate: the military-grade NFC Metal Card (IP68, MIL-STD-810, AES-128) unlocks access and signs transactions with a tap — an access companion, not key storage.
Start using WATS in three steps
From install to your first signed transaction in minutes — no prior crypto setup required.
- 1
Install WATS
Add the Chrome extension or install the iOS / Android app from the official stores — or open the Hot Wallet in your browser at web.watswallet.com with nothing to install.
- 2
Add funds
In the self-custody extension and app you pay each chain's own native gas. In the Hot Wallet you top up a single fee token, ATS, that covers swaps, transfers and staking across every chain.
- 3
Tap to authenticate
Pair the NFC Metal Card and tap it to your phone to authenticate access and sign transactions. Your keys stay in the app — the card is an access companion, not key storage.

What is WATS Wallet?
WATS Wallet is a non-custodial, multi-product Web3 wallet available as a Chrome extension, mobile app, web hot wallet and an NFC metal card.
Is WATS Wallet free to use?
Yes — the Chrome extension, mobile app and Hot Wallet are all free to use. In the self-custody Chrome extension and mobile app you pay each chain's own native gas fee; in the WATS Hot Wallet every action (swap, transfer or staking) is instead paid in a single fee token, ATS, which covers the live network cost rather than acting as a discount.
Which chains does WATS Wallet support?
WATS Wallet supports major EVM chains as well as Solana and TON, so you can send, receive, swap and bridge across all of them from a single interface.
Is WATS Wallet custodial or non-custodial?
WATS Wallet is non-custodial — you control your own keys. The WATS Hot Wallet always uses a dual-custody model where the user and WATS each hold a key for added security.
What is the ATS token used for in WATS Wallet?
In the WATS Hot Wallet, ATS is the single fee token: every action such as swaps, transfers and staking is paid in ATS instead of multiple native gas tokens.
How does the WATS NFC Metal Card work?
The WATS NFC Metal Card is a military-grade physical card with an embedded NTAG 216 chip; you tap it to an NFC-enabled phone to authenticate and secure your WATS Wallet accounts.
Who makes WATS Wallet?
WATS Wallet is built and operated by Alltoscan LLC, a company founded in 2019, and was last updated on June 28, 2026.
Is WATS Wallet safe?
WATS Wallet is non-custodial, so you hold your own keys. The Hot Wallet uses a dual-custody model where you and WATS each hold a separate key, and the NFC Metal Card uses an NTAG 216 chip with AES-128 encryption for tap-to-authenticate access.
How much does the WATS NFC Metal Card cost?
The WATS NFC Metal Card is sold through the WATS store at store.watswallet.com, where current pricing and material options — brushed stainless steel or polycarbonate — are listed.
What happens if I lose my WATS NFC Metal Card?
Losing the card does not put your funds at risk. The NFC Metal Card only authenticates access to your WATS Wallet — it is not your only key and it never stores your crypto. Keep using the WATS mobile app or Chrome extension as usual, remove the lost card from your paired devices in the WATS app, and order a replacement at store.watswallet.com. Step-by-step recovery is documented at wats.gitbook.io/wats.
Can I use WATS Wallet on both my phone and my computer?
Yes. WATS is one identity across four products: a mobile app for iOS and Android, a Chrome extension for desktop browsers, a web-based Hot Wallet, and the NFC Metal Card — all tied to the same wallet.
Do I need the ATS token to use WATS Wallet?
The Chrome extension and mobile app are free to install and use. In the WATS Hot Wallet, ATS is the single fee token used to pay for actions such as swaps, transfers and staking, instead of holding each chain's native gas token.
What languages does WATS Wallet support?
The WATS Wallet site and interface support 12 languages: English, Turkish, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Korean and Arabic.
How do I download WATS Wallet?
Go to watswallet.com/download — it detects your device and sends you to the App Store, Google Play or the Chrome Web Store. The Hot Wallet runs in your browser at web.watswallet.com with nothing to install.
What makes WATS Wallet different from other crypto wallets?
WATS combines four products under one identity — a Chrome extension, a mobile app, a web Hot Wallet with a single ATS fee token, and a military-grade NFC Metal Card — so you get browser, mobile, web and physical access from one self-custodial wallet.
Is WATS Wallet a hot wallet or a cold wallet?
WATS is mainly a non-custodial hot wallet you control on your phone, browser and the web. The NFC Metal Card adds a physical tap-to-authenticate and tap-to-sign step on top, so you get a hardware security layer without WATS becoming a single offline cold card.
Do I have to complete KYC to use WATS Wallet?
No. WATS Wallet is self-custodial software, so you create a wallet and start using the Chrome extension, mobile app or Hot Wallet without identity verification, and you alone hold the keys.
Can I swap and bridge tokens inside WATS Wallet?
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. In the Hot Wallet, those swaps and bridges are paid for in the single ATS fee token.
Does WATS Wallet support staking?
Yes. Staking is one of the actions in the WATS Hot Wallet, and like swaps and transfers it is paid for in the single ATS fee token instead of each chain's native gas.
Is WATS Wallet good for beginners?
Yes. WATS keeps everyday Web3 simple: one identity works across the extension, mobile app, web Hot Wallet and NFC card, and the single ATS fee token means you don't have to buy a different gas coin for every chain — all while you keep full self-custody of your keys.
