Polymarket Integrates Spark, Enabling Instant Deposits via Bitcoin Lightning Network

Odaily reported that Polymarket has integrated Spark, a Bitcoin Layer 2 payment protocol, allowing users to make instant deposits via the Bitcoin Lightning Network.

According to the report, Spark will provide underlying payment infrastructure for Polymarket, enabling users to deposit directly with BTC, with funds arriving in seconds. Compared to traditional on-chain Bitcoin transfers, which take 30 minutes to 1 hour for confirmation, this offers faster speed, lower costs, and greater privacy. This integration is also part of Polymarket's ongoing efforts to enhance the Bitcoin payment experience, following its earlier move to support Bitcoin deposits. (Digital Assets)
