The ATS single-token fee model
The ATS fee model is the WATS Hot Wallet's single-token fee system: every action — swaps, transfers and staking — is paid in one token, ATS, instead of each chain's native gas token. This is gas abstraction, so you no longer hold separate gas for every network, and it pairs with WATS dual-custody security.
How an ATS fee works
- 1
Start an action in the Hot Wallet
Begin a swap, transfer or staking action in the WATS Hot Wallet at web.watswallet.com.
- 2
WATS estimates the network cost
The Hot Wallet calculates what your action will cost on the underlying chain.
- 3
The fee is charged in ATS
Instead of the chain's native gas token, the fee is settled in the single ATS token.
- 4
The action confirms
Your transaction completes while you only managed one fee token across every chain.

Frequently asked questions
What is the ATS fee model in WATS Wallet?
The ATS fee model is the WATS Hot Wallet's single-token fee system: every action — swaps, transfers and staking — is paid in one token, ATS, instead of each chain's native gas token. This gas abstraction means you do not need to hold separate native gas for each network.
Why does WATS use a single ATS fee token instead of native gas?
A single ATS fee token gives you gas abstraction: you pay every Hot Wallet action in one token rather than holding ETH, SOL, TON and other native gas separately. It simplifies multi-chain use and pairs with WATS dual-custody security.
How is the ATS fee calculated?
When you start an action in the Hot Wallet, WATS estimates the underlying network cost and then charges the fee in ATS instead of the chain's native gas token. WATS does not publish a fixed amount or formula here; current fee details are in the WATS documentation at wats.gitbook.io/wats.
Does the ATS fee model change who controls my keys?
No. WATS is non-custodial, so you control your keys. The ATS fee model pairs with the Hot Wallet's dual-custody security, where the user and WATS each hold a separate key — paying fees in ATS does not change that arrangement.
