Sparkling: the trading app that comes with an agent

Sparkling 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 from the same self-custodial balance. Swaps between tokens use Bebop. Perpetual futures execute on Hyperliquid, an onchain exchange. Prediction markets are offered generically as a third market type. The idea is that you do not have to move funds between separate apps to reach each of them.

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 too. 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 it ends with a Confirm button. Nothing happens until Confirm is pressed.

The agent does not decide for you and does not give investment advice. It cannot see your keys and cannot sign a transaction. If the card cannot be built, Sparkling shows an error and nothing is executed. That is the point of the line "AI preps every move. You confirm."

In practice the agent saves the legwork of finding the right venue, filling in the order and checking the numbers, while the decision and the signature stay with you. You can read the card, change your request, or close it with nothing having happened.

Agents

Agents prepare. You decide.

Each agent specializes in one type of trade — you always decide which one to use.

Perpetuals Leveraged long and short positions with built-in risk limits.
Predictions Take a position on the outcome of real-world events.
Agent-prepared execution Prepare and rebalance your positions across perpetuals, predictions, and swaps as markets move — you approve every trade.
Swaps Find your route across DEXs, bridges, and swaps.

The trade card puts everything in view before you confirm

Every move in Sparkling 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 you confirm
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 you confirm.

Your keys stay with you

Sparkling is self-custodial: every account is created with a seed phrase that you can export at any time, the keys are secured by Turnkey, and you sign every transaction yourself. With the exported seed phrase, funds stay accessible in compatible software independently of Sparkling. Sparkling is an interface to third-party markets and 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.

How Sparkling works

This section describes the flow in general terms. Availability of individual features depends on the jurisdiction.

  1. An account is created with a seed phrase, which can be exported at any time.
  2. Crypto is brought in from a supported network. Deposits are gasless.
  3. You tell the agent what you want to do, for example a swap.
  4. The agent prepares a trade card with the asset, amount, venue, price, slippage, fees and risk check.
  5. You read the card and press Confirm only if you agree with every line.
  6. The seed phrase is kept safe, because it is the only way to recover funds outside Sparkling.

The web app is coming soon.

Swaps, perps and prediction markets: the basics

A swap exchanges one token for another at the current market price. In Sparkling, swaps use Bebop.

A perpetual future, or perp, is a contract that tracks the price of an asset without an expiry date. Perps usually use leverage, so a small move in price can change the result by much more than the move itself. In Sparkling, perps execute on Hyperliquid, and the risk check on the trade card summarises the main risks of each trade.

A prediction market lets you take a position on the outcome of an event, with a price between 0 and 1 dollar that reflects the probability the market assigns to it. Each of these products has its own risks, summarised below.

Product Where it executes What it is for Main risk
Swaps Bebop Moving from one token to another Slippage and price moves
Perps Hyperliquid Tracking the price of an asset, often with leverage Leverage magnifies losses
Prediction markets Third-party markets Taking a position on the outcome of an event The position can lose its full value

Risks and availability

Trading swaps, perps and prediction markets involves substantial risk, including the loss of all funds, and it is not suitable for everyone. Perpetual futures use leverage, which can magnify losses. Prices can move quickly, and a trade can execute at a different price than expected because of slippage. Tax rules may apply to crypto; check official guidance or a professional.
