# Fees and Gas

> Platform fees, network costs, routing costs, and gas sponsorship in o1 Mobile.

Every swap quote can include several types of cost. Review the quote before
confirming a transaction.

## Platform fee

The current o1 Mobile platform fee is **1% of the swap amount**.

The mobile platform fee does not change based on:

* cashback or referral programs;
* points or reward tiers;
* holding or staking \$O;
* a \$O balance;
* access to web-only tools; or
* a \$O-based feature tier.

o1 Mobile does not use rewards, points, referrals, cashback, or \$O to unlock
functionality or change the mobile platform fee. Mobile swaps do not generate
a claimable crypto-asset reward.

## Network and routing costs

Other costs can vary by transaction:

* blockchain network fees;
* decentralized liquidity-provider fees;
* bridge or cross-network routing costs; and
* third-party service costs.

These costs are not fixed by the mobile platform-fee rate. The available quote
and route determine which costs apply.

## Gas sponsorship

Some routes support sponsored transaction costs. When sponsorship is
available, the app identifies the route as sponsored and the user may not need
the source network's native gas asset for that transaction.

When sponsorship is unavailable, the wallet may need enough native currency
to cover the network fee.

<Note>
  Gas sponsorship is route-dependent and is not guaranteed for every network,
  token, amount, or transaction.
</Note>

## Before confirming

Review:

1. the input amount;
2. the estimated output;
3. the platform fee;
4. any network or routing cost shown by the app; and
5. the minimum expected result after price movement or slippage.

Quotes can expire or change before execution.
