# Swap Fees

## One fee, and it pays you back

onchain.cc charges **0.50%** per swap — and **25% to 50% of every fee comes back to you as** [**cashback**](/onchain-docs/colosseum/cashback.md), set by your Colosseum rank and claimable in USDC. The same fee and cashback apply to [Trenches](/onchain-docs/trenches/trading.md) trades.

| Rank      | Cashback | Net cost of a 0.50% fee |
| --------- | -------- | ----------------------- |
| Recruit   | 25%      | 0.375%                  |
| Warrior   | 30%      | 0.35%                   |
| Gladiator | 35%      | 0.325%                  |
| Champion  | 40%      | 0.30%                   |
| Warlord   | 45%      | 0.275%                  |
| Immortal  | 50%      | 0.25%                   |

The fee is shown in the swap panel before you confirm, and each trade's cashback lands in your Cashback panel live — see [Cashback](/onchain-docs/colosseum/cashback.md) for how accrual, claiming, and expiry work. Traders active before the September 2026 restructure are automatically grandfathered onto a better cashback ladder that preserves their previous net rates.

{% hint style="info" %}
Most competing terminals charge around 1% per trade with nothing back. Counted net of cashback, onchain.cc remains among the cheapest ways to trade on any terminal — and the more you climb, the wider the gap gets.

## Network fees (gas)

Every on-chain transaction also carries the network's own gas fee — paid to the chain, not to onchain.cc.

* **Sponsored on most EVM chains** — Base, Arbitrum, Optimism, Polygon, Linea, Scroll, Gnosis, Berachain, and Robinhood swaps don't need you to hold the native token.
* **Solana, Ethereum, and BNB** — keep a small native-token balance (fractions of a cent per transaction on Solana; more on Ethereum mainnet).

{% hint style="info" %}
Scope: this schedule covers **Swap and Trenches**. [Spot](/onchain-docs/spot/fees.md), [Perps](/onchain-docs/perps/fees.md), and [Predictions](/onchain-docs/predictions/overview.md) have their own fee structures — and cashback applies to all of them.
