Sparkling, a self-custodial trading platform, has launched its web application at app.sparkl.ing, extending its trading terminal and AI-assisted features to browser-based users. The move aims to cater to traders who prefer the larger interface and comprehensive data display that a desktop browser offers, while retaining the platform's core principles of self-custody and user-controlled execution.
The web version provides a wider trading layout, including an order book and more market data on a single screen. This design gives traders a fuller view of market conditions, enabling them to size positions, set leverage, place orders, and manage open trades without switching between apps or wallets. The platform supports perpetual futures, prediction markets, tokenized US stocks, and token swaps, all accessible from one unified account.
Sparkling's key differentiator is its optional AI agent, which can assist in trade preparation but never executes transactions autonomously. Users can either trade directly through the interface or instruct the agent to prepare a trade, which then presents a transaction card with all parameters filled in. The user reviews, adjusts, or rejects the proposal before confirming, ensuring that every transaction is user-approved. Private keys remain under the user's control, and the agent has no access to them.
“The browser is still where many traders feel at home, so that is where Sparkling had to be. On the web they get the room they are used to, and the agent steps in only when they call it,” said Daniil Kotlov, CEO of Sparkling.
The platform offers two distinct trading flows: the Pre-Executed Flow, where users type their intent in plain language and receive a ready transaction card, and a manual mode for those who prefer to handle every detail themselves. This flexibility allows traders to switch between approaches trade by trade, depending on their preference for convenience or control.
“Some traders want to type what they need and get a ready trade back. Others want the order book in front of them and every setting in their own hands. Most products pick one of those people. Sparkling now serves both from the same account, and the trader decides which way to work, trade by trade,” said Aleksei Voiutskii, founder of NODES, Sparkling’s exclusive marketing partner.
Under the hood, Sparkling's self-custodial accounts are built on Turnkey wallet infrastructure, allowing users to export their seed phrase at any time. Perpetual futures are executed on Hyperliquid, prediction markets come from Polymarket (where Sparkling is a verified builder), tokenized US stocks are provided by xStocks, and swaps run on Bebop's RFQ-based execution. These integrations are designed to provide broad coverage across tokens and chains.
“The safest agent is one that cannot move your money. In Sparkling, it can prepare a trade, but only the user can approve it,” said George Kaspar, Head of AI at Sparkling.
The launch comes amid growing interest in AI-assisted trading tools and unified platforms. Sparkling's approach emphasizes safety and user control, distinguishing it from fully automated solutions. The web app is available now, with a Telegram bot also offered for mobile access.
