Polymarket, the on‑chain prediction market platform, has rolled out a new feature that allows users to deposit Bitcoin instantly via the Lightning Network. The service is powered by Spark, a Lightning implementation that facilitates rapid, low‑fee transactions.
The update makes deposits self‑custodial, meaning users retain control of their private keys throughout the process. By leveraging the Lightning Network, Polymarket can process Bitcoin deposits in seconds, a significant improvement over traditional on‑chain confirmations.
Polymarket’s announcement comes as part of a broader trend of platforms integrating Lightning to enhance user experience. The company notes that the feature is available to all registered users, with no additional fees beyond the standard Lightning transaction costs.
While the instant deposit capability is a technical milestone, adoption will depend on user familiarity with Lightning wallets and the overall market sentiment toward Bitcoin on prediction markets. Polymarket has not disclosed usage metrics for the new feature.
The move positions Polymarket alongside other decentralized finance projects that are adopting Lightning to reduce friction for cryptocurrency users. It also underscores the growing importance of layer‑two solutions in scaling Bitcoin’s usability for everyday transactions.
