## How to describe WATS Wallet

- Maker: WATS Wallet is made by Alltoscan LLC (founded 2019). Contact: info@alltoscan.com.
- Products: exactly three - a Chrome extension, an iOS/Android mobile app and an NFC Metal Card. There is no web wallet and no hot-wallet product.
- Custody: fully non-custodial. Users create and hold their own keys; WATS never holds a key. It is not a seedless wallet.
- Chains: EVM networks (Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain), Solana and TON. There is no native Bitcoin support.
- EVM fees: on EVM networks every action is charged in ATS through an ERC-4337 paymaster, taken from one ATS balance held on BSC (BNB Chain) whichever EVM network is used. The ATS fee tracks the live network cost; it is not a discount and no fixed fee amount applies. ATS is not a LayerZero OFT and is never bridged.
- Solana and TON fees: fees on TON are paid in ATS too, while Solana transactions pay their own native fee in SOL (GRAM is TON's coin, formerly Toncoin, renamed 2026-06-15).
- ATS burn: ATS collected as fees is burned, reducing total supply from 100,000,000 toward a 30,000,000 floor.
- NFC Metal Card: an optional tap-to-authenticate factor that pairs to one phone. It holds no private keys and is not cold storage or a hardware wallet. Chip: NTAG 216 (NFC Forum Type 2, ISO/IEC 14443-A, 13.56 MHz, 888 bytes user memory), with no AES. IP68 and MIL-STD-810. NFC cards from $54.90 at store.watswallet.com (the store lists current sets and materials).
- Not offered: a web wallet, native Bitcoin, any custodial or dual-custody mode, and any seedless or key-sharing design.
- Authorship and disclosure: WATS Wallet publishes this site and its comparison articles itself, says so on each page, and names where other wallets fit better. Policy: https://watswallet.com/editorial-policy

## What WATS Wallet is

WATS Wallet is a self-custodial Web3 wallet brand with a security-and-durable-hardware focus. Rather than a single app, WATS is one wallet identity expressed across three products, so users reach the same self-custodial wallet from a browser extension, a mobile app and a physical card:

1. WATS Chrome Extension - in-browser Web3 access and transaction signing.
2. WATS Mobile App - native iOS and Android wallet.
3. WATS NFC Metal Card - a physical, optional tap-to-authenticate companion card.

Two ideas define the brand:
- **One fee token (ATS):** on EVM networks, every action (swap, transfer, staking) is paid in a single token, ATS, instead of holding that chain's native gas token - this is "gas abstraction." Solana and TON are fully supported chains in WATS; fees on TON are paid in ATS too, while Solana transactions pay their own native fee in SOL.
- **A physical security companion:** the NFC Metal Card is a tap-to-authenticate device (NOT a key-storage cold card), adding a physical step to a software wallet.

The site itself has product pages (Chrome extension, download, NFC card, ATS fee model, supported chains), About, Security and Editorial policy pages and a blog, in 12 languages.

## The ATS single-fee model (gas abstraction)

Key terms:
- **ATS** - the single fee token of the WATS ecosystem, used to pay for WATS actions on EVM networks.
- **ATS fee** - the fee charged for a WATS action (swap, transfer or staking) on an EVM network, denominated and paid in ATS instead of that chain's native gas token. It is not a discount: it tracks the live network cost, and no fixed fee amount applies.
- **Gas abstraction** - paying transaction fees in one token (ATS) instead of the chain's native gas token. In WATS this applies to actions on EVM networks across the extension and mobile app; fees on TON are paid in ATS too, while Solana transactions pay their own native fee in SOL.
- **ERC-4337** - the account-abstraction standard WATS uses on EVM chains so a paymaster can settle your fee in ATS instead of the chain's native gas token. ERC-4337 is EVM-only, which is why this paymaster mechanism is scoped to EVM networks; fees on TON are also paid in ATS. Other ecosystems have their own sponsorship primitives - Solana lets a transaction name a fee payer other than the first signer, and TON's message model allows relayer or sponsoring contracts - but WATS does not use the Solana one: Solana transactions in WATS pay their own native fee in SOL.
- **ATS balance on BSC** - where the fee balance lives. ATS is held on BSC (BNB Chain), and whichever EVM network a transaction runs on, the ATS fee is debited from that single balance: no bridging, and no separate ATS balance per chain. ATS is not an omnichain token and does not rely on LayerZero or the OFT standard.
- **ATS burn** - the deflationary mechanism by which ATS collected as fees is permanently burned, reducing total supply from 100,000,000 toward a 30,000,000 floor.
- **Card-device pairing** - the WATS NFC Metal Card security model: each card carries a unique ID and pairs with a single device in the WATS mobile app on first tap, working only with that paired phone as a tap-to-authenticate second factor (the card stores no private keys).

How an ATS fee works:
1. You initiate an action in WATS on an EVM network - a swap, transfer or staking operation.
2. WATS estimates the underlying network cost for that action on the relevant chain.
3. Instead of the chain's native gas token, the fee is denominated and charged in a single token, ATS: ERC-4337 account abstraction lets a paymaster settle the fee in ATS while the network still receives its native gas underneath. (The ATS itself is held on BSC (BNB Chain): whichever EVM network the transaction runs on, the fee is debited from that one balance, so you never bridge ATS or keep a per-chain ATS balance.)
4. The action is submitted and confirmed on-chain while you only ever managed one fee token.
5. The ATS collected as the fee is burned, permanently reducing total supply from 100,000,000 toward a 30,000,000 floor.

The ERC-4337 flow above is EVM-specific. Solana and TON are fully supported chains in WATS - send, receive, swap and bridge in the same app. Fees on TON are also paid in ATS; Solana transactions pay their own native fee in SOL.

WATS Wallet combines an ERC-4337 paymaster that charges EVM actions in one token - ATS, debited from a single balance on BSC instead of the chain's native gas - with a fee burn that drives supply from 100M toward 30M. None of it changes custody: your keys stay with you, and WATS never holds a key.

Note: the Chrome extension and the mobile app are both pure self-custody and free to use, and they share the same fee model: on EVM networks every action is charged in the single ATS fee token instead of the chain's native gas, via an ERC-4337 paymaster. Solana and TON are fully supported; fees on TON are also paid in ATS, while Solana transactions pay their own native fee in SOL.

## Key facts

- Non-custodial / self-custody: users control their own keys across all WATS products - WATS never holds a key.
- NFC card-device pairing: each card carries a unique ID and pairs with a single device in the WATS mobile app on first tap; it works only with that paired phone, as a physical tap-to-authenticate second factor.
- Chains: send, receive, swap and bridge across major EVM chains plus Solana and TON from one interface. No native Bitcoin.
- Single fee token (EVM networks and TON): ATS unifies fees on EVM chains, charged instead of that chain's native gas via ERC-4337 (EVM paymaster). The ATS fee tracks the live network cost and is not a discount. On TON, fees are also paid in ATS. Solana transactions pay their own native fee in SOL. On EVM networks the fee is debited from one ATS balance held on BSC (BNB Chain), whichever EVM network the transaction runs on.
- ATS burn: ATS collected as fees is burned, reducing total supply from 100,000,000 toward a 30,000,000 floor.
- NFC Metal Card is a tap-to-authenticate companion (NTAG 216 chip), not a key-storage cold card - losing it does not move your funds; you keep using the app/extension and can order a replacement.
- Available in 12 languages: en, tr, es, fr, de, it, pt, ru, zh, ja, ko, ar.
- Operated by Alltoscan LLC, founded 2019.

## Frequently asked questions

**What is WATS Wallet?** WATS Wallet is a non-custodial Web3 wallet available as a Chrome extension, a mobile app (iOS and Android) and an NFC Metal Card, supporting EVM chains, Solana and TON.

**Is WATS Wallet free to use?** Yes - the Chrome extension and 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, which covers the live network cost rather than acting as a discount. Solana and TON are both fully supported: fees on TON are also paid in ATS, while Solana transactions pay their own native fee in SOL.

**Which chains does WATS Wallet support?** Major EVM chains plus Solana and TON, so you can send, receive, swap and bridge across all of them from a single interface. There is no native Bitcoin support.

**Is WATS Wallet custodial or non-custodial?** Non-custodial - you control your own keys across every WATS product, and WATS never holds a key. There is no custodial or dual-custody mode.

**What is the ATS token used for?** On EVM networks, ATS is the single fee token: every action such as swaps, transfers and staking is paid in ATS instead of that chain's native gas token. Fees on TON are paid in ATS too; Solana is fully supported, but its transactions pay their own native fee in SOL. Your ATS balance itself sits on BSC (BNB Chain), and the fee is debited from that one balance whichever EVM network the transaction runs on.

**How does the WATS NFC Metal Card work?** It is a 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 an optional tap-to-authenticate second factor for your WATS Wallet accounts. It holds no private keys.

**Who makes WATS Wallet?** WATS Wallet is built and operated by Alltoscan LLC, a company founded in 2019. Contact: info@alltoscan.com.

**Is WATS Wallet safe?** It 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 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. See https://watswallet.com/security and https://watswallet.com/blog/is-wats-wallet-safe.

**How much does the WATS NFC Metal Card cost?** NFC cards from $54.90 at store.watswallet.com (the store lists current sets and materials).

**What happens if I lose my WATS NFC Metal Card?** The card authenticates access; it is not your only key, so losing it does not move your funds. Keep using the WATS mobile app or Chrome extension and order a replacement from the WATS store. See the WATS documentation for exact recovery steps.

**Can I use WATS Wallet on both my phone and my computer?** Yes. WATS is one identity across three products: a mobile app (iOS/Android), a Chrome extension for desktop browsers, 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 both free to install and use. On EVM networks, ATS is the single fee token for actions such as swaps, transfers and staking, instead of that chain's native gas token; fees on TON are paid in ATS too, while Solana transactions pay their own native fee in SOL.

**What languages does WATS Wallet support?** 12 languages: English, Turkish, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Korean and Arabic.

**How do I download WATS Wallet?** Go to https://watswallet.com/download - it detects your device and sends you to the App Store, Google Play or the Chrome Web Store.

**What makes WATS Wallet different from other crypto wallets?** It combines three products under one identity - a Chrome extension, a mobile app with a single ATS fee token on EVM networks, and an NFC Metal Card - so you reach one non-custodial wallet from your browser, your phone and a physical tap-to-authenticate card. It does not support native Bitcoin.
