Sparkling Crypto: the trading app that comes with an agent
Sparkling Crypto is the trading app that comes with an agent: swaps, perps and prediction markets from one self-custodial balance. The agent prepares every move, you confirm it, and your keys stay with you.

One balance for swaps, perps and prediction markets
Sparkling brings three kinds of market activity into one app, all drawn from the same self-custodial balance. Swaps between tokens are routed through Bebop. Perpetual futures execute on Hyperliquid, an onchain exchange. Prediction markets are included as a third market type. The idea behind the Sparkling crypto app is that a trader does not have to move funds between separate tools to reach each of these markets.
Crypto can also be bought with a bank card in supported regions. Deposits are gasless, so crypto can be brought in from a supported network without holding a separate gas balance, and trading on perps and prediction markets is gasless as well. Availability of individual features depends on the jurisdiction.
The agent prepares every move and you confirm
In Sparkling you describe what you want in plain words, for example “swap 200 USDT into ETH”. The agent then prepares a trade card that shows the asset, the amount, the venue, the price, the slippage, the fees and a risk check, and the card ends with a Confirm button. Nothing is executed until Confirm is pressed.
The agent does not decide for you and does not give investment advice. The language model behind it never sees your keys and cannot sign a transaction. If a card cannot be built, Sparkling shows an error and nothing is executed. That is the meaning of the line “AI preps every move. You confirm.”
In practice, the agent takes over the legwork of finding the right venue, filling in the order and checking the numbers, while the decision and the signature stay with the user. A card can be read, changed by rephrasing the request, or closed with nothing having happened.
The trade card puts everything in view before confirmation
Every move in Sparkling Crypto goes through the same card, so the same information appears each time. The table lists what the card contains and why each line matters.
| Card line | What it tells you |
|---|---|
| Asset | What is being bought, sold or traded |
| Amount | How much is being traded |
| Venue | Which market the trade goes to |
| Price and slippage | The expected price and how far it can move before the trade executes |
| Fees | What the trade costs, shown before confirmation |
| Risk check | A summary of the main risks of this specific trade |
| Confirm | The only step that executes the trade |
Sparkling charges a fee on trades, and every card shows the fees before confirmation.
Self-custody keeps the keys with the user
Sparkling is self-custodial: every account is created with a seed phrase that can be exported at any time, the keys are secured through Turnkey, and the user signs every transaction. With the exported seed phrase, funds remain accessible in compatible software independently of Sparkling. Sparkling is a self-custodial software interface operated by Swarming Labs Ltd (BVI). Sparkling never holds user funds.
Self-custody also means responsibility. Whoever has the seed phrase controls the funds, so it should be written down offline, never shared, and never kept in a screenshot or a cloud note. If a seed phrase is lost and no backup exists, nobody can restore access, and that is true of any self-custodial setup.
How Sparkling works
This section describes the flow in general terms. Availability of individual features depends on the jurisdiction. The web app is available, so the same flow can be used in a browser.
-
An account is created with a seed phrase, which can be exported at any time.
-
Crypto is brought in from a supported network, or bought with a bank card in supported regions. Deposits are gasless.
-
The user tells the agent what they want to do, for example a swap.
-
The agent prepares a trade card with the asset, amount, venue, price, slippage, fees and risk check.
-
The user reads the card and either confirms it or closes it.
-
On confirmation, the user signs and the trade is sent to the venue. If anything fails, nothing is executed.

Swaps, perps and prediction markets compared
The three market types behave differently and carry different risks. The table summarises the main differences in general terms.
| Market type | What it is | Main thing to watch |
|---|---|---|
| Swaps | Exchanging one token for another, routed through Bebop in Sparkling | Slippage and the price at execution |
| Perps | Perpetual futures, which let you take a position on an asset price with leverage, executed on Hyperliquid | Leverage can magnify losses, up to the loss of all funds |
| Prediction markets | Markets where you take a side on whether an event happens | The outcome can be binary, so a position can lose its full value |
Perps and prediction markets are not available everywhere. Availability of individual features depends on the jurisdiction, and Sparkling applies IP-based geoblocking in line with the terms of the markets it connects to and applicable restrictions. Using a VPN or other means to circumvent these restrictions violates our Terms of Service.
Risks to understand before trading anything
Sparkling Crypto is a tool for preparing and confirming trades, not a way to remove risk. Crypto prices can move sharply. Perpetual futures and prediction markets carry substantial risk, including the loss of all funds. Trades prepared by the agent are not recommendations, and the risk check on a card is a summary, not a guarantee.
Third-party markets can also have their own rules, outages and restrictions. Tax rules may apply to crypto activity, so check official guidance or a professional. Nothing on this page is investment, tax or legal advice.
