Sparkling fees, every cost shown before you sign
Crypto costs often hide in spreads, slippage and network charges that appear only after you click. Sparkling puts all of it on the confirmation card. This page explains each part, what drives it and how to keep it down.
What makes up the cost of a swap
| Part | Who receives it | What drives it |
|---|---|---|
| Network fee (gas) | Blockchain validators or miners | Network demand and transaction complexity |
| Service fee | Sparkling | Applied when a swap executes |
| Price impact and slippage | Not a fee, a price difference | Trade size and available liquidity |
Opening an account, asking the agent questions, getting quotes and holding coins in the wallet cost nothing.
What are gas fees in crypto?
Gas is what you pay a blockchain to process a transaction. It goes to the network, not to Sparkling, and it varies with demand: Ethereum is usually the most expensive of the supported networks, while Solana and TON typically cost a fraction of a cent to a few cents. Bitcoin fees depend on how busy the network is. The agent shows the current network cost for each route.
How to keep swap costs low
- Ask the agent which network is cheapest for the move you want to make.
- Use Solana or TON for frequent small transfers of stablecoins.
- Avoid very small trades on Ethereum, where gas can be a large share of the amount.
- Split large orders if the card shows high price impact.
- Check the total on the card and cancel if it doesn’t make sense.
Questions about how quotes are built can go straight to the AI trading agent inside the app.
Are crypto fees tax deductible?
In the US, transaction costs are generally added to your cost basis when you buy and subtracted from proceeds when you sell or swap, rather than deducted separately. The Sparkling history lists each confirmed swap so the figures are easy to find. Ask a tax professional how this applies to you.
Why fees are shown, not promised
Network fees change minute to minute, so a fixed number on a web page would be wrong by the time you trade. That is why Sparkling shows the actual figure for your trade at the moment you review it. For background on who runs the service, see is Sparkling legit.
