What part of a swap fee goes to the exchange and what goes to the network

05 September 2026

None of the fee you pay for a swap is paid to the blockchain. Every bit of it goes to the exchange. The network fee is a separate charge, not a slice of the swap fee.

The confusion is understandable. When you see a number labelled "fee" on a swap page, it is almost always the exchange's markup. The network fee is listed elsewhere, often under "gas" or "network cost." They are two different payments for two different services.

Why the exchange takes all of the swap fee

The swap fee is the price the exchange charges for finding you a counterparty and executing the trade. It covers the exchange's operating costs: servers, staff, liquidity sourcing, and profit. The blockchain does none of that work. The blockchain only validates and records the final transaction. It does not find a buyer, match an order, or hold your funds in escrow while the trade settles. So the network gets none of that fee.

Think of it like paying a broker to buy stock. The broker's commission pays for their service. The stock exchange (the venue where the trade clears) charges a separate clearing fee. The two are not the same pot of money.

What the network fee actually is

The network fee (gas) is paid to miners or validators for including your transaction in a block. It is a payment for computational work and for the opportunity cost of using block space. You pay it regardless of whether you are swapping, sending, or interacting with a smart contract. The exchange does not control this fee. It passes through the exchange to the network.

On some swap interfaces, the network fee is bundled into a single displayed cost. That can make it look like the swap fee is being split. It is not. The interface is simply showing you the total you will spend: exchange markup plus gas. The gas still goes entirely to the network. The markup still goes entirely to the exchange.

The spread is also the exchange's money

A separate cost is the spread: the difference between the market price of an asset and the price the exchange actually gives you. That spread is also exchange revenue. It is not a fee in the formal sense, but it is money you lose to the exchange by accepting a worse price. The network sees none of that either.

This is important because a swap that advertises "zero fees" may still be costing you money through a wide spread. The exchange is still taking its cut; it just calls it something else.

Where your total cost really goes

When you complete a swap on seapresale.xyz, your total outflow breaks into three parts:

1. The exchange's swap fee - goes entirely to the exchange.
2. The spread - goes entirely to the exchange (or to the liquidity provider, depending on the model, but never to the network).
3. The network fee - goes entirely to the blockchain's validators or miners.

None of these overlap. None of them are shared. The network is paid exactly for confirming the transaction, nothing more.
