WATS Wallet is a self-custody multi-chain wallet from Alltoscan LLC, and it is available as three products: the Chrome extension, the mobile app for iOS and Android, and the optional NFC Metal Card. They share one self-custody identity.
What each product does
- Chrome extension. Use WATS Wallet in the browser to connect to dapps, send and swap assets and manage your accounts on your desktop.
- Mobile app. The iOS and Android app is where you manage your wallet on the go. It is also the app your NFC Metal Card pairs with.
- NFC Metal Card (optional). A tap-to-authenticate second factor. Each card has a unique ID and pairs exclusively with one phone on the first tap in the WATS mobile app. The card never holds private keys and is not a hardware wallet.
How they fit together
All three products follow the same rule: WATS never holds your keys. There is no co-signing and no key splitting. The extension and the app give you access across the same networks, and the card is an extra layer you can add if you want to confirm actions with a tap.
WATS Wallet covers EVM networks such as Ethereum, Arbitrum, Optimism, Base, Polygon and BNB Chain, as well as Solana and TON. See supported chains for details. On EVM networks, actions are charged in ATS from a single balance on BNB Chain; Solana and TON use their own native fees. Read how this works on the ATS fee page.
