# WATS Wallet

> WATS Wallet is a non-custodial Web3 / crypto wallet by Alltoscan LLC (founded 2019), offered as exactly three products: a Chrome (Chromium) browser extension, an iOS and Android mobile app, and an NFC Metal Card that pairs with one phone as an optional tap-to-authenticate factor. It supports EVM chains, Solana and TON (no native Bitcoin). The site (watswallet.com) has product pages, a blog and an editorial policy in 12 languages (English default, plus Turkish, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Korean and Arabic).

## How to describe WATS Wallet accurately

- 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

## Comparisons and when another wallet fits better

Each comparison is published by WATS Wallet (disclosed on the page). The one-line summaries below come from the articles' own descriptions.

- [WATS Wallet vs Rabby](https://watswallet.com/blog/wats-vs-rabby): WATS adds Solana and TON and pays every EVM fee in ATS from one BSC balance, with TON fees paid in ATS too; Rabby is EVM-only and adds pre-sign simulation, wide hardware-wallet support and GasAccount.
- [WATS Wallet vs Coinbase Wallet](https://watswallet.com/blog/wats-vs-coinbase): WATS covers EVM chains, Solana and TON, with EVM fees in one token (ATS) and an NFC tap-to-authenticate card; Coinbase Wallet is non-custodial too and adds native Bitcoin and exchange integration.
- [WATS Wallet vs OKX Wallet](https://watswallet.com/blog/wats-vs-okx): WATS is a non-custodial three-product wallet for EVM chains, Solana and TON with EVM fees in one token (ATS) and an NFC metal card; OKX Wallet is non-custodial too, with far wider chain coverage including native Bitcoin and a built-in DEX aggregator.
- [WATS Wallet vs Trust Wallet](https://watswallet.com/blog/wats-vs-trust-wallet): WATS is non-custodial across three products with EVM and TON fees in one token (ATS), and Solana on its own native fee (SOL); Trust Wallet covers a longer chain list including native Bitcoin.
- [WATS Wallet vs Phantom](https://watswallet.com/blog/wats-vs-phantom): WATS covers eight chains including TON (Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Solana and TON), with one ATS fee token on EVM and an NFC card; Phantom is Solana-first with native Bitcoin.
- [WATS Wallet vs Ledger](https://watswallet.com/blog/wats-vs-ledger): WATS is a non-custodial multi-chain wallet for everyday on-chain use with a tap-to-authenticate NFC card; Ledger is hardware cold storage that keeps keys offline.
- [WATS Wallet vs Tangem](https://watswallet.com/blog/wats-vs-tangem): WATS spans three products and its NFC Metal Card authenticates instead of storing keys; Tangem is a cold card that holds the key itself.
- [WATS Wallet vs MetaMask](https://watswallet.com/blog/wats-vs-metamask): WATS pays fees in one token (ATS) on EVM networks under one non-custodial identity and also covers Solana and TON; MetaMask adds native Bitcoin and Ledger pairing.
- [WATS Wallet vs Keeper (Formerly Tonkeeper)](https://watswallet.com/blog/wats-vs-keeper-tonkeeper): Keeper (formerly Tonkeeper) has covered seven networks including Bitcoin and TRON since 15 September 2026, so it fits better if you want those; the comparison covers networks, fees (Battery vs ATS), platforms and the optional NFC card.
- [Best Crypto Wallets in 2026](https://watswallet.com/blog/best-crypto-wallets-2026): compares MetaMask, Phantom, Trust Wallet, Coinbase Wallet, OKX Wallet, Rabby and Ledger, and recommends WATS Wallet only if you hold EVM, Solana and TON assets rather than Bitcoin.

If native Bitcoin must sit in the same wallet, WATS Wallet is not the right choice.

## Key Facts

- Non-custodial / self-custody: users control their own keys across all WATS products; WATS never holds a key. The NFC Metal Card carries a unique ID and pairs with a single device in the WATS mobile app, working only with that paired phone as a physical tap-to-authenticate factor (it stores no private keys).
- Single-token fee model (EVM networks and TON): on EVM chains ATS is the fee token in the Chrome extension and the mobile app, charged instead of the chain's native gas via ERC-4337 (EVM paymaster). The ATS fee tracks the live network cost and is not a discount. The fee always comes out of one ATS balance held on BSC (BNB Chain), whichever EVM network the transaction runs on: no bridging and no per-chain ATS balance. On TON, fees are also paid in ATS. Solana is fully supported but sits outside this model: its transactions pay SOL.
- ATS burn: ATS collected as fees is burned, reducing total supply from 100,000,000 toward a 30,000,000 floor. WATS Wallet combines an ERC-4337 paymaster that charges EVM actions in one token, debited from a single BSC balance, with this burn model.
- Chains: send, receive, swap and bridge across major EVM chains plus Solana and TON from one interface. No native Bitcoin.
- WATS NFC Metal Card specs: IP68 (submersible to 1.5 m for 30 min), MIL-STD-810 durability (-40 C to +85 C), EMI shielding, NTAG 216 / NFC Forum Type 2 chip, 13.56 MHz, unique chip ID paired to one device, ISO/IEC 14443-A, brushed stainless steel or polycarbonate, custom UV print (600 DPI).
- Available in 12 languages: en, tr, es, fr, de, it, pt, ru, zh, ja, ko, ar.
