Polymarket integrates Lightning Network via Spark for instant BTC deposits, eliminating 10-60 minute onchain confirmation delays.
DeFi & Yields ·
Polymarket has integrated Bitcoin Lightning Network deposits through Spark, enabling users to fund accounts instantly rather than waiting for traditional onchain confirmations. The integration eliminates the 10–60 minute delays associated with standard Bitcoin settlement, allowing deposits to be credited immediately upon Lightning transaction completion.
Spark is a decentralized lending platform built within the Sky ecosystem, originally launched in 2023 by Phoenix Labs as a development arm seeded by MakerDAO governance. The protocol functions as a specialized money market for borrowing USDS stablecoins against crypto collateral, with deep integration into Sky's monetary policy framework. SparkLend, its core product, forks Aave v3's lending architecture and supports collateral including Ethereum, liquid staking tokens, and wrapped Bitcoin.
The mechanics of how Polymarket specifically implemented Lightning deposits through Spark's infrastructure remain unclear from available reporting. The extent to which this integration may expand to other platforms or represent a broader strategic partnership between the projects has not been specified.
